Importance sampling techniques significantly reduce variance in physically based rendering. In this article, we propose a novel online framework to learn the spatial-varying distribution of the full product of the rendering equation, with a single small neural network using stochastic ray samples. The learned distributions can be used to efficiently sample the full product of incident light. To accomplish this, we introduce a novel closed-form density model, called the Normalized Anisotropic Spherical Gaussian mixture, that can model a complex light field with a small number of parameters and that can be directly sampled. Our framework progressively renders and learns the distribution, without requiring any warm-up phases. With the compact and expressive representation of our density model, our framework can be implemented entirely on the GPU, allowing it to produce high-quality images with limited computational resources. The results show that our framework outperforms existing neural path guiding approaches and achieves comparable or even better performance than state-of-the-art online statistical path guiding techniques.

Room-scale VR has been considered an alternative to physical office workspaces. For office activities, users frequently require planar input methods, such as typing or handwriting, to quickly record annotations to virtual content. However, current off-the-shelf VR HMD setups rely on mid-air interactions, which can cause arm fatigue and decrease input accuracy. To address this issue, we propose UbiSurface, a robotic touch surface that can automatically reposition itself to physically present a virtual planar input surface (VR whiteboard, VR canvas, etc.) to users and to permit them to achieve accurate and fatigue-less input while walking around a virtual room. We design and implement a prototype of UbiSurface that can dynamically change a canvas-sized touch surface's position, height, and pitch and yaw angles to adapt to virtual surfaces spatially arranged at various locations and angles around a virtual room. We then conduct studies to validate its technical performance and examine how UbiSurface facilitates the user's primary mid-air planar interactions, such as painting and writing in a room-scale VR setup. Our results indicate that this system reduces arm fatigue and increases input accuracy, especially for writing tasks. We then discuss the potential benefits and challenges of robotic touch devices for future room-scale VR setups.

We present a framework that captures sparse Lagrangian flow information from a volume of real liquid and reconstructs its detailed kinematic information in real time. Our framework can perform flow reconstruction even when the liquid is disturbed by an object of unknown movement and shape. Through a large dataset of liquid moving under external disturbance, an agent is trained using reinforcement learning to reproduce the target flow kinematics with only the captured sparse information as inputs while remaining oblivious to the movement and the shape of the disturbance sources. To ensure that the underlying simulation model faithfully obeys physical reality, we also optimize the viscosity parameters in Smoothed Particle Hydrodynamics (SPH) using classical fluid dynamics knowledge and gradient-based optimization. By quantitatively comparing the reconstruction results against real-world and simulated ground truth, we verified that our reconstruction method is resilient to different agitation patterns.

Abstract Research efforts have previously explored various components of physical/virtual workspaces that adaptively interact with knowledge workers in order to support them in their work. In this paper, we propose an encompassing framework for these efforts, which we refer to as Human-Workspace Interaction (HWI), with the goal of increasing awareness and understanding of the research area and encouraging its further development. Specifically, we present a taxonomy of HWI focusing on the types of components, research approaches, interaction targets and objectives, and then review the prior research efforts over the past two decades based on these criteria. Finally, we discuss challenges to further advance the development of HWI and future prospects, taking into account the impact of the societal changes caused by the COVID-19 pandemic.

TetraForce: A Magnetic-Based Interface Enabling Pressure Force and Shear Force Input Applied to Front and Back of a Smartphone

We propose a novel phone-case-shaped interface named TetraForce, which enables four types of force input consisting of two force directions (i.e., pressure force and shear force) and two force-applied surfaces (i.e., touch surface and back surface) in a single device. Force detection is achieved using the smartphone's built-in magnetometer (and supplementary accelerometer and gyro sensor) by estimating the displacement of a magnet attached to a 3-DoF passively movable panel at the back. We conducted a user study (N=12) to investigate the fundamental user performance by our interface and demonstrated that the input was detected as intended with a success rate of 97.4% on average for all four input types. We further conducted an ideation workshop with people who were involved in human-computer interaction (N=12) to explore possible applications of this interface, and we obtained 137 ideas for applications using individual input types and 51 possible scenarios using them in combination. Organizing these ideas reveals the advantages of each input type and suggests that our interface is useful for applications that require complex operations and that it can improve intuitiveness through elastic feedback.
HandyGaze: A Gaze Tracking Technique for Room-Scale Environments using a Single Smartphone

We propose HandyGaze, a 6-DoF gaze tracking technique for room-scale environments that can be carried out by simply holding a smartphone naturally without installing any sensors or markers in the environment. Our technique simultaneously employs the smartphone’s front and rear cameras: The front camera estimates the user’s gaze vector relative to the smartphone, while the rear camera (and depth sensor, if available) performs self-localization by reconstructing a pre-obtained 3D map of the environment. To achieve this, we implemented a prototype that works on iOS smartphones by running an ARKit-based algorithm for estimating the user’s 6-DoF head orientation. We additionally implemented a novel calibration method that offsets the user-specific deviation between the head and gaze orientations. We then conducted a user study (N=10) that measured our technique’s positional accuracy to the gaze target under four conditions, based on combinations of use with and without a depth sensor and calibration. The results show that our calibration method was able to reduce the mean absolute error of the gaze point by 27%, with an error of 0.53 m when using the depth sensor. We also report the target size required to avoid erroneous inputs. Finally, we suggest possible applications such as a gaze-based guidance application for museums.

Head-mounted displays (HMDs) increase immersion into virtual worlds. The problem is that this limits headset users' awareness of bystanders: headset users cannot attend to bystanders' presence and activities. We call this the HMD boundary. We explore how to make the HMD boundary permeable by comparing different ways of providing informal awareness cues to the headset user about bystanders. We adapted and implemented three visualization techniques (Avatar View, Radar and Presence++) that share bystanders' location and orientation with headset users. We conducted a hybrid user and simulation study with three different types of VR content (high, medium, low interactivity) with twenty participants to compare how these visualization techniques allow people to maintain an awareness of bystanders, and how they affect immersion (compared to a baseline condition). Our study reveals that a see-through avatar representation of bystanders was effective, but led to slightly reduced immersion in the VR content. Based on our findings, we discuss how future awareness visualization techniques can be designed to mitigate the reduction of immersion for the headset user.

Building higher-quality image classification models requires better performance analysis (PA) to help understand their behaviors. We propose ConfusionLens, a dynamic and interactive visualization interface that augments a conventional confusion matrix with focus+context visualization. This interface allows users to seamlessly switch table layouts among three views (overall view, class-level view, and between-class view) while observing all of the instance images in a single screen. We designed and implemented a ConfusionLens prototype that supports hundreds of instances, and then conducted a user study (N \(=\) 14) to evaluate it compared to the conventional confusion matrix with a split view of instances. Results show that ConfusionLens achieved faster task-completion time in observing instance-level performance and higher accuracy in observing between-class confusion. Moreover, we conducted an expert interview (N \(=\) 6) to investigate the applicability of our interface to practical PA tasks, and then implemented several extensions of ConfusionLens based on the feedback. Feedback on these extensions from users experienced in image classification (N \(=\) 5) demonstrated their general usefulness and highlighted their beneficial use in PA tasks.

Abstract With the advancement of AI‐generated human motion, it is of increasing importance to think about how we distinguish real human motion from machine‐generated movements. In this study, we recruited professional performers to use the whole body to make a short movement to inform potential observers that they are real humans (instead of machines). Their movements were captured with a motion capture system (Vicon) and later reduced to dynamic point‐like displays (biological motion). They were interviewed after the recording to provide their acting strategies. Naive observers who did not participate in the motion data collection were recruited to watch these videos and judge whether the biological motions looked human‐like or not (YES/NO), as well as to report their judging criteria. The major factors extracted from these reports include kinematics, context, body mechanics, and principles of physical laws. We discuss the impact of these criteria and how they may possibly help improve the future generation of human‐like motions.

This paper proposes TransformTable, an interactive digital table, whose shape can be physically and dynamically deformed. Shape transformations are mechanically and electrically actuated by wireless signals from a host computer. TransfomTable represents digital information in a physically changeable screen shape and simultaneously produces different spatial arrangements of users around the table. This provides visual information while changing the physical workspace to allow users to effectively handle their tasks. We implements the first TransformTable prototype that can deform from/into one of three typical shapes: round, square, or rectangular. We also discuss implementation methods, further application designs and scenarios. A preliminary user study shows fundamental and potential social impacts of the table transformation on users' subjective views in a group conversation.

We present a media art work "Mysterious POND", which gives a mysterious illusion for multiple users on a digital table using a revolving polarizer. It normally shows users a waving water surface, but only the users embodying "Sansai ", an oriental philosophy, can watch carps in underwater by illuminating the water surface with a magic lantern. For embodying "Sansai", the user needs to be under the sun or the moon, and wear glasses. This paper describes the theory and its implementation of Mysterious POND, followed by some sceneries of the demonstrations. Finally, the future extensions of the work are discussed from the results of the demonstrations.

We propose an umbrella-like device called Funbrella that entertains people with many types of rain by focusing on an umbrella as a user interface that connects humans and rain. Generally, people experience rain with sound, sight, or sometimes smell; however, in our proposed system, we exploit the vibration perceived through an umbrella's handle so that people can feel the rain. We implemented a vibration-giving mechanism based on a dynamic microphone and a dynamic speaker whose structures are almost identical. With this structure, Funbrella records the vibrations caused by raindrops and plays them. We implemented two applications: Crazy Rain and Tele-rain. One is to feel various kinds of rain, and the other transmits rain to different places in real time. With such applications, people can enjoy rain that is usually annoying.

We propose a system that allows multiple groups of users at remote locations to naturally share a 3D image of real objects. All users can interactively observe a 3D stereoscopic image without distortion from their own viewpoints. The system basically consists of a combination of systems: imaging and display. The imaging system generates images of the real object observed from arbitrary viewpoints based an image-based rendering technique implemented on GPU. The display system generates a 3D virtual image of the real object based on the IllusionHole technique. Users at one place just put the real object on their imaging system to capture a set of its images from sparse viewpoints around it; other groups of multiple users at remote places connected by networks observe its virtual image from arbitrary viewpoints, as if there is a copy of the real object, on their display systems.

Rain changes its complexion based on the time and the place. Each aspect of rain provides a unique impression, so experiencing it in distant places and different times would be a new way of sharing information. To represent rain, we focused on an umbrella as a user interface to connect humans and rain. Generally, people experience rain with sounds, sights, or sometimes smells; however, in our proposed system, we exploit the vibration perceived through an umbrella's handle to let people feel the rain. With Funbrella, you will find how many complexions rain has because it gives you opportunities to feel and enjoy various kinds of rain that is recorded as real vibration data with itself.

We are proposing the IllusionHole system, which allows three or more moving people to simultaneously observe individual stereoscopic image pairs from their own viewpoints. With a simple configuration, it provides intelligible 3D stereoscopic images free of flicker and distortion. Based on the idea of the IllusionHole, a prototype is established with two short throw DLP projectors and polarization filters. Since the prototype has no obstacles on the chassis, every side has an equal capability of being used to observe 3D objects. This paper describes details of the prototype.

We propose a system design including the architecture, data flows, and communication protocols etc. to realize a seamless multi-display environment (MDE). Our interaction architecture combines distributed input and position tracking data to generate perspective-corrected output in each of the displays, allowing groups of users to manipulate existing applications from current operating systems across a large number of displays. To test our design we implemented a complex MDE prototype and measured different aspects of its performance. Then we discuss the results of the measurements and the potential availabilities.

We propose a modeling system that enables users to create tree models with 3D gesture input. It generates tree models by using growth simulation based on the trunk or silhouette shapes of trees given by user gestures. The system carefully addresses the fragile balance and tradeoff between the freedom of user interaction and the autonomy of tree growth. Users intuitively and easily create tree models that have the exact features of branching structures or the silhouette shape of trees according to user intentions and imagination.

This paper presents a method of interactively generating whole body animation using reduced dimensionality from multiple captured data sequences of whole body motions. The proposed method is achieved by two techniques; automatic motion segmentation and estimation of the posture using multiple regression analysis. Even when the skeletal structure of the user who inputs the motion is different from that of the shape model in the computer, the motion that the user imagines is generated. The proposed method generates animation naturally, just as users would expect.

We propose the Delphian Desktop which enables to predict spatial user intensions to reduce the time required to point to faraway targets in GUIs. Predictions are calculated by tracking cursor movement and estimating the user goal location using inexpensive online algorithm based on the linear peak cursor velocity-distance to target relationship. Once the system detects the peak velocity during pointing movement, the automatic cursor jump toward predicted point is performed. In testing the Delphian Desktop effectively shortened pointing time for 800 pixel or longer target distance and reduced the physical mouse movement.

We propose a method of generating tree models which enables users to generate, manipulate and edit the shape of tree models based on growth simulation by using direct three-dimensional (3D) input. For this purpose, three-dimensional (3D) spatial information is introduced to the well-known L-system as an attribute of the growth simulation. Moreover, we propose an efficient data structure of L-strings in order to speed up the generating process of tree models.

We propose a method of skeleton generation for 3D models. The proposed method works in real time. It consists of five steps: 1) transformation into the low polygon model from the original model that composed a large number of polygons, 2) calculation of the sum of geodesic distances from specific points to all vertices on the 3D model, 3) subdivision of the 3D model using the sum of geodesic distances, 4) generation of skeleton joints (skeleton node) on the each boundary surface between those subdivision areas, and 5) connection of each skeleton nodes. We also propose the method for flexible skeleton generation using boundary shapes and the sum of geodesic distances. By using this method, the skeletons can be generated in the area where the user specified. Accordingly, it is expected that user can create flexible animations of 3D models in real time.

In this paper, we describe a novel function of ActiveCube that realizes intuitive interaction with multimedia contents. First we realize a new method that reduces the host PC's load by distributed control between the host PC and cubes. Secondly, we reduce unnecessary packets in the network between the host PC and cubes using autonomy and encapsulation of each cube. Then we conducted experiments to evaluate the performance of the proposed system. Finally, we developed an example application for children and observed children's actual actions.

We propose a real-time method to generate character animation of whole body while holding stick-like tools by using only three 6DOF trackers. This method is achieved by introducing estimation with regression analysis based on the variables obtained from the 6DOF trackers attached to the subject's shoulder, waist, both elbows, both knees and the tool. On the execution period, the animation of character is generated by estimating the unknown DOFs such as joints of elbow and knee, by using the established regression formula with three 6DOF trackers attached to the shoulder, the waist, and the tool as the inputs. Here, the method assumes the fixed foot position and holding tools with his both hands as constraints, and joint angles of both elbows and both knees are calculated by inverse kinematics. As the result, we could generate natural character animation of whole body by using the proposed method.

This paper presents a method of interactively generating natural hand animation using reduced dimensionality from multiple captured data sequences of finger motions conducting specific tasks. This method is achieved by introducing an estimation with multiple regression analysis. Even when the skeletal structure of the user who inputs the motion is different from that of the shape model in the computer, the motion that a user imagines is generated. Moreover, by introducing a real-time recoginition of hand motions with DP matching, the user is able to conduct multiple finger motions one after another. This method enables us to make input devices that require minimal user training and computer calibration, and helps to make the user interface intuitive and easy to use.

We propose a method to extract the motion individuality from the form of a sport expert and to apply it to the characters that have different segment length. For this purpose, a standard motion is established by removing a subjective motion from an actor who conducts a sport skillfully, and the surface features (angular velocity and torque of the joint) is extracted for each joint angle difference in the each animation frame between the original motion of the sports expert and the standard motion. The surface features and relative timing in the deep structure are transmitted to the characters having different segment length by applying them to the standard motion of the characters whose subjective motion is also removed in advance.

This paper proposes a method of consolidated manipulation of virtual and real objects using a "magnetic metaphor". The method reduces the difference of behavior between the virtual and real objects. Therefore, it enables a user to manipulate virtual and real objects in the similar manner by expecting the same response and behavior according to the same physical laws. Experimental results show that the proposed method improves the task performance of the manipulation of virtual and real objects.

This paper describes a simplified real-time 3D modeling technique for objects extracted from video images by an efficient algorithm in order to produce multimedia contents. An object contained in video images which is extracted at a reasonable speed is reconstructed in a proposed augmented virtuality system with sufficient accuracy. Moreover, real object interactions that meet such criteria must be established using techniques for manipulating objects in virtual worlds. The proposed technique has potential to generate novel multimedia contents without using complicated shape modeling. An interactive digital fishtank is described as one example application of the proposed technique. In this application, the user is able to obtain augmented virtuality world of fishtanks from the original video sequence.

The recent progress in graphics computations has created opportunities to construct various virtual environments, such as urban or natural scenes. Furthermore, such environments can be enriched with a photograph from the world as a texture image. In walk-through of a virtual environment, it is important to represent motion parallax following viewpoints according to user's movement. This paper describes a method to create a realistic distant scenery in a virtual environment using panoramic real images taken by an omnidirectional stereo imaging sensor.

We propose an efficient and simple method for finding a collision-free path and orientation for a rigid robot in a 3-D environment for Unmanned Aerial Vehicles (UAVs) . The method uses an octree for representing every object (robot and static/dynamic obstacles) in the environment without any distinction of the movability of objects; therefore, all objects are dealt with in the same way. The path of a robot from its starting position to the given goal with arbitrary motion (i.e., translation and rotation) in a 3-D environment is efficiently searched for in successive adjoining regions (octree white nodes) by using the potential field generated from each black node of the octree. The algorithm is simple, so it can easily be accelerated by using parallelization techniques. Experimental results obtained under several conditions are reported, and finally, the efficiency of the proposed method against the complexity of the environment are discussed.

We propose a parallel algorithm that efficiently generates an octree from a polyhedral shape representation. The algorithm is simple and applicable to general (non-convex) objects. The parallelized algorithm is based on two ideas for the assignment of multiple processors. The algorithm was implemented and tested on MIMD multi-processors having a shared memory. Experimental results demonstrate the effectiveness and efficiency of the proposed method : for example, only 2.5 seconds are required to generate an octree shape representation from a polyhedral object having 148 polygons. We discuss the performance of the proposed parallel algorithm and the features of the parallelism.

We propose an accurate and efficient method for detecting potential collisions among multiple objects with arbitrary motion (translation and rotation) in three-dimensional (3-D) space. The algorithm can be used directly for both convex and concave objects. The method consists of two main stages. In the first, coarse stage, an approximate test is performed to identify interfering objects in the entire workspace using octree representation of object shapes. In the second, fine stage, polyhedral representation of object shapes is used to more accurately identify any object parts that might cause interference and collisions. For this purpose, specific pairs of faces belonging to any of the interfering objects found in the first stage are tested, thus performing detailed computation on a reduced amount of data. Experimental results, which demonstrate the efficiency of the proposed collision detection method with adequate octree are given.

Because vitrual reality techniques can be used to provide an intuitive user interface using human spatial perception, they are promising methods for implementing a sophisticated user interface. Limitations in computational power, however, make it difficult to present a perfect virtual environment, and a simple task in a real environment therefore often becomes a skilled operation in a virtual environment. This paper describes a method enabling an operator in a virtual environment to place an object on a surface without any force-feedback tool. When a grabbed object comes to close to another object, it is attached. Experimental results show that the method is efficient in decreasing the time required for object placement when precise placement necessary.

For recognition of 3-D shape and measurement of 3-D position of objects, it is important that a vision system can measure the 3-D data of dense points in the scene. One approach is to measure the distance on the basis of triangulation principle from the disparity of two images. This binocular vision method has, however, a difficult problem that is to find correspondence of features between two images. This correspondence problem can be solved geometrically by adding one more camera, that is, by trinocular vision.<BR>This paper presents the principles and implementation details of this trinocular vision. Based on the proposed method, we have made several experiments. By these experiments, it is found that many correct correspondence can be established even for images of complex scene by only geometrical constraint of the trinocular vision. However, when there are dense edge points in the image, multiple candidate points are found and unique correspondence cannot be established. To solve this problem, we will discuss two approaches in this paper.

We explored effects of interactive content visualization with dynamic layouts and two kinds of context-adapted content in public settings. Two field studies were conducted based on video analysis and post-questionnaire in order to investigate how the visualization design engages people and how the two kinds of social-event-adapted content can have different impacts on passerby's engagements. The first study focused on event-oriented content (introduction of the event) in an academic exhibition with 585 visitors while the second study investigated user-oriented content (floor map of the venue) in a similar-style industrial exhibition with 3500 visitors. Result showed that our dynamic visualization successfully engaged 12% of passersby into interaction and further led to overall positive interaction experiences. Our video analysis revealed clear differences between the two types of the content. We also discuss some challenges of content and visualization design for public touch surface.

This work validated effects of improvisation workshop on group discussion by analyzing subjective ratings from participants and objective measurements of their non-verbal behaviors by sensors during the discussion tasks. We compared two group discussion tasks with 8-person which were held before and after the improvisation workshop. The subjective evaluation confirmed positive effects of the improvisation on the subsequent discussion in terms of participants' encoding ability, decoding ability, assertiveness, satisfaction with group discussion, and intragroup conflict (task conflict). Also, an analysis of the non-verbal behaviors showed that volume of voices and hand gestures of participants increased after the workshop.

In this paper. we examine an interpersonal communication support method that produces user's spatial behaviors by using dynamically a self-propelled digital table. In our method, the digital tables are automatically moved according to an estimated conversational activity in order to provide a comfortable and more dynamic conversational space through changing their positions and group structures. An evaluation revealed that the movement of the table significantly influenced their spatial behaviors. We discussed the possibility of application of the self-propelled digital table in conversational situations.

This study experimentally examines relationships between such nonverbal behaviors as degree of speech, hand gestures, head direction and body distance, and subjective evaluation of an activity of atmosphere created during a six-person conversation, in order to establish an estimation model of atmosphere in interpersonal communication. A conversation group consisted of three males and females who met for the first time, and they talked for 12 minutes overall and rated the activity of atmosphere during conversation. Our results with regression analysis shows that speech time, crosstalk with 4 persons, hand gestures, and size of conversational space had high correlation with the subjectively rated atmosphere. Throughout some analyses, we discussed fitness of the several regression models compared to the estimation model for triadic conversation.

The purpose of this study was to examine how a transition of the conversation would occur among strangers, when they were to engage in multiple conversations and also to investigate how the transition would be associated with the atmosphere, and nonverbal behavior, such as the number of gesture, .head turning toward partner, the amount of utterance. In the experiment, 66 university students an unacquainted with one another participated as one of three-person group participated in dyadic and triadic conversations. Then, the influence of dyadic conversation on following triadic conversation was analyzed particularly in regard with the perceived activation level of atmosphere and nonverbal behavior.

The purpose of this study was to examine correlations among skill of building relationships, nonverbal behaviors (i.e. hand movements, interpersonal distance, head direction and the amount of utterance) and personality in a dyadic conversation. A total of 66 undergraduates (51 males and 15 females) participated in this experiment. The results were that skill of building relationships was positively correlated with ACT, self-monitoring and hand movements, and it was also negatively correlated with LSO-U. In addition, LSO-U was positively correlated with the amount of utterance.

From a Brunswikian lens model approach, this study examined relationships between nonverbal cues (i.e. hand movements, interpersonal distance, head direction and the amount of utterance) and skill of building relationships. A total of 66 undergraduates (51 males and 15 females) participated in this study. Participants rated their own skill of building relationships and were also rated by their conversational partners. Moreover, independent raters, who were not in this experiment, rated all participants on the skill. As a result, hand movements were perceived as a good indicator of the skill by those who actually exhibited as well as by their conversational partners and the independent raters.

This study also investigated effect of information (topic) presentation by a display located in the conversation situation. Three participants who were the same generation and met for the first time talked for 8 minutes overall and then rated the activity of atmosphere of their own conversation presented by video every two minutes. Out results showed that the degree of speech and the hand gestures had a high correlation with subjective atmosphere while the head movement and the speech bias had a low correlation. Our results also revealed that the information presentation affected conversation and these correlations.

We are developing a display system named IllusionHole which provide stereoscopic images for multiple users. It allows three or more collocated users to share a stereoscopic image. Users can work cooperatively in face to face situation around this system. We carried out an experiment to examine how users' collocation and conversation affect task performance and user's behavior in the collaborative work. Results show that the collocation and conversation do not affect task performance but affect behaviors of cooperative work.

We often work in an office or a meeting room with multiple displays simultaneously or collaborate with several persons. In these environments, however, displays are not always located facing to the user ; as a result, a user often find difficulties in correctly understanding spatial relationships of objects on the display, reading texts, manipulating objects, and so on. In this paper, we carried out an experiment to compare perspective correction regarding locations of a user and displays and traditional flat display method in five basic interaction tasks. The results show that the perspective correction significant and substantial performance in all the tasks.

We propose a method for generating realistic, controllable animation by splicing motion graphs. In our method, we represent the motion as upper-body action and lower-body locomotion. The method first constructs action motion graphs and locomotion motion graph. It next generates lower-body locomotion along user's paths and splices the upper-body action using spatial relationships between the action and the locomotion motion graph of the upper-body. By this approach, we realize controllable animation generation while reducing the number of motions.

Photorealistic image synthesis in computer graphics is formulated as light transport problem. Path tracing algorithm is basic method to solve the light transport problem. And that algorithm is most efficient method to solve the problem with a scene whose indirect illumination and whole domain of integration are important. The path-tracing algorithm generates sample paths, and to decide a path length the algorithm uses some random-walk strategy. This article proposes a new random walk strategy based on particle filter to reduce variance of Monte-Carlo estimator.

Strategic negotiations in digital tabletop displays have not been well understood. There is little reported in the literature on how users strategize when group priorities and individual priorities conflict and need to be balanced for a successful collaboration. We conducted an observational study on three digital tabletop systems and a real-world setup to investigate similarities and differences in real-world and digital tabletop strategic collaborations. Our results show that in the real world, strategic negotiation involves three phases : identifying the right timing, using epistemic actions to consider a task plan and evaluating the value of the negotiation. We repeated the real-world experiments with different digital tabletops and found several differences in the way users initiate and perform strategic negotiations.

In this paper, we investigate pointing tasks in a three-dimensional environment. We focus on the kinematic characteristics during pointing movement in order to evaluate difficulty of depth perception in the environments. Experiments are conducted to investigate effects of target distaces, size, angles, and visual feedback on velocity profile during pointing movement. Results from user study show that peak velocity is scaled by depth distance user perceives whether absence or presence of visual feedback. The peak velocity is affected by target angle as a depth cue. Movement time follows typical Fitts' law and target angle is also effective for reducing pointing time.

A video of a few minutes length is used as an input and it is managed as a unit by the database. The unit of the database is composed of the extracted target's images and features of the target. Agents are created by combining demands given by a user. The agent autonomously decides its action and generates query by its cognitive sensors and emotional model. The most felicitous sequence of images of the agent is retreved from the database and then presented.

We propose a voxelization method of a polyhedral model using uniformly point-sampled representation in 3D shape model retrieval. Because the original vertices are generally biased, it is difficult to voxelize a polyhedral model. In order to solve the problem, we use point-sampled representation for the polyhedral model, and voxelize the model. Thus, it is not dependent on original vertices density. Finally, we compare the voxel data which are defined by using the original vertices and uniformly point-sampled representation for the polyhedral model.

IllusionHole is an interactive display system that allows three or more moving observers to simultaneously observe stereoscopic image pairs from their own viewpoints. One of the drawbacks of the IllusionHole is the fact that image drawing areas of multiple users sometimes overlap each other when they stand at closed positions even if the design parameters are carefully set. In this paper we propose two solutions to this problem based on the consideration to the design parameters. The one is to dynamically change the size of the users' image drawing areas according to the users' motions, and the other is to integrate image drawing areas when their corresponding viewpoints come within a certain threshold of proximity to each other.

Blinking has a dramatic impact on our impression of a fellow person. Synthetic blinking is widely used in virtual characters and avatars, in animated cartoons, movies, and video games. Correctly controlling the virtual blinking can possibly create more (or less) attractive characters and directly influence the impression these characters leave with the media users. We designed a blinking control system that allows simple dynamic changes of virtual human blinking patterns using a realistic and physiologically-valid computer graphics (CG) model. We evaluated our virtual blinking system in a controlled psychological experiment comparing the impression it left on users with the impression a blinking human actor left. In this paper, we describe our system and the psychological evaluation we conducted. We discuss the possibilities and limitations of attempting to control human impressions by direct control of our virtual blinking model.

We propose a method of generating tree models by using growth simulation from trunk shapes given by gestures. Growth simulations enable users to generate realistic shapes of tree models. However it is difficult to generate the shapes of them which are imaged in user's mind, because these shapes depend on production rules which are defined beforehand. In order to generate tree models efficiently, our method generates the shapes of tree models by using growth simulation which generates models based on trunk shapes given by gestures. Also our method corrects the trunk shapes which user makes and avoids the collision of trunks. This enables users to make intuitively complex shapes of tree models which image in user's mind.

Active-Cube allows users to construct and interact with three dimensional (3D) environments using physical cubes equipped with input/output devices. We have developed various applications using ActiveCube that utilize sophisticated I/O devices or require much CPU power of the host PC. In this paper, we propose and implement a new method that reduces the burden of the host PC by sharing the procedure between the host PC and cubes. Furthermore, we propose and implement a method that restricts unnecessary packets in the network between cubes and host PC by realizing the autonomic movement of each cube.

We propose a model that generates emotions of autonomous agents in an interactive environment where multiple agents live. The model consists of three modules, I.e., cognitive process, emotional process and behavior process, and generates a variety of natural emotions of each agent. In the cognitive process, environmental information is obtained by using adequate software sensors and sent to the emotion process. Here, the emotion of each agent is generated by a fuzzy technique and a memory module. Both generated emotions and transitions of these emotions are quite natural because we employed an improved technique of Minsky's social theory. The actions or behaviors of each agent and their strengths are determined by using the generated emotions and the physiological parameters which expresses the condition of each agent. In this paper, we describe details of the proposed model. In addition, an application example of the proposed model applied to autonomous control of video objects is explained.

The adequate presentation of environmental overviews from multiple viewpoints in different scales assists the user in accurately recognizing the spatial environment. In order to achieve an intuitive control of viewpoint and orientation of multiple cameras, we describe a method for intuitively controlling multiple additional viewpoints using Multiple Interlocked Motion of Coordinate Pairs. We classify manipulation of viewpoints introducing properly three kinds of restrictions into the pairs of coordinate systems, and we investigate some examples of manipulation of multiple viewpoints control method with the pairs of coordinate systems.

To realize a novel user interface which allows a user to interact with a computer intuitively, we have proposed the ActiveCube system. With this system, a user can construct and interact with a 3D environment by using cubes equipped with an input/output device. In this paper, we describe a method to realize constructing more flexible structure by controlling recognition signals of each face of each cube. And we propose a method to implement sophicticated input/output devices, which require more I/O ports, by adding another microprocessor into cubes.

In order to form human relationships between strangers, it is necessary to deepen mutual understanding by talking about their interests and individual information. Moreover, in many cases, these topics depend on the place and space where they are talking. However, in virtual space, there is a problem that human relationships could not be formed smoothly because conversation does not become lively for the unfamiliar surroundings and poverty of information about a partner. Thus, we propose the communication support system that promotes formation of human relationships. In conversation, it offers topics to users by presenting the spatial information relevant to the contents of their conversation. This paper describes implementation details and results of evaluation on the proposed system.

In this paper, we propose a new technique based on recent neuroimaging studies as a tool for the assessment of interface. For this purpose, we analyze the learning process by two different approaches. One is an experiment on task performance based on the conventional testing method of a user interface, and the other is a method based on recent neuroimaging studies that estimate the process of interaction through the observation of the human brain activities. The result showed the possibility that the observation of the human brain activities become a new technique for assessmentof interface.

Steering law is a performance model of trajectory-based task, however it is only examined in 2D indirect pointing environment with small enough objective pointer and trajectory of certain width. This paper discusses about the extension of the steering law. We prove the steering law in 2D direct pointing environment. Furthermore we explore the three conditions of the pointer and trajectory, i. e., the small enough pointer and the trajectory of certain width, the pointer of certain size and the thin enough trajectory, and the pointer of certain size and the trajectory of certain width.

This paper presents a method of interactively generating natural hand animation using reduced dimensionality from multiple captured data sequences of finger motions conducting specific tasks. This method is achieved by introducing an estimation with multiple regression analysis. Even when the skeletal structure of the user who inputs the motion is different from that of the shape model in the computer, the motion that a user imagines is generated. Moreover, by introducing a real-time recoginition of hand motions with DP matching, the user is able to conduct multiple finger motions one after another. This method enables us to make input devices that require minimal user training and computer calibration, and helps to make the user interface intuitive and easy to use.

This paper describes a real-time morphing technique in virtual environment. The proposed technique automatically makes features of source object to correspond to those of target one. Textures and shapes are deformed separately, because source and target objects are renewed frame by frame. The proposed morphing technique can replace the virtual object with the other in database without influencing others in virtual worlds. And it is implemented in the supporting system to creat real-time contents. Then, the morphing technique proposed in this paper is evaluated, and validity is checked.

This paper describes a real-time morphing technique in virtual environment. The proposed technique automatically makes features of source object to correspond to those of target one. Textures and shapes are deformed separately, because source and target objects are renewed frame by frame. The proposed morphing technique can replace the virtual object with the other in database without influencing others in virtual worlds. And it is implemented in the supporting system to creat real-time contents. It is shown that the proposed technique is able to deform objects in real-time.

This paper proposes a method to manipulate objects with chopsticks in a virtual environment. Here, the exact interactions in multiple stages are introduced, i.e., between hand and chopsticks, and chopsticks and object. For the interaction between hand and chopsticks, constraints coming from the correct table manner are implemented to operate chopsticks correctly. An exact real-time interference detection algorithm for polygonal objects is also used to prevent interference between hand and chopsticks. On the other hand, two methods to pick up virtual objects are proposed for the interaction between chopsticks and object, i.e., an approximated test using a chopsticks-pointer and a bounding box of an object, and exact test using polygonal shape representations.

This paper describes navigation and manipulation methods in a virtual nature environment. We propose a technique to use a "birds eye" overview display of entire large-scale virtual environment. It enables user to navigate efficiently even in enormous and complicated environments. A user is able to maintain a sense of relative size compared with his body in the immersed virtual environment. Multiple overview images taken by virtual cameras at multiple viewpoints and scales efficiently assists the user to obtain accurate spatial perception of the virtual environment. Moreover, a user can efficiently manipulate virtual objects in enormous and complicated environments through both life-size images and "birds eye" overview images. Promising results in a virtual nature environment implemented on a graphics workstation show the possibility of our proposed system.

A natural method is proposed to help a user manipulate an object in a virtual environment using visual- and haptic-feedback-based methods. It uses visual constraints among object faces that are dynamically selected while the user manipulates the object. At the same time, the user's hard motion are restricted with a force feedback device which generate a reaction between two faces touching each other. 6 DOF for precise object manipulation with 3 DOF force display is possible by using a visual-feedback-based manipulation aid. In addition, by using a haptic-feedback-based manipulation aid, the user does not get a sense of incompatibility caused by differences between his hand motion and visually constrained object motion. The properties of manipulation aid based on these two feedbacks are discussed. Experimental results show the effectiveness of our proposed method of manipulation aid using visual- and haptic-feedbacks.

We propose an efficient method for detecting potential collisions among multiple objects with arbitrary motion(translation and rotation)in three-dimensional(3-D)space.The method is useful for on-line monitoring and path planning in a 3-D environment in which there are multiple independently moving objects.The method consists of two main stages.In,the first,coarse stage,an approximate test is performed to identify interfering objects in the entire workspace using octree representation of object shapes.In the second,fine stage,polyhedral representation of object shapes is used to more accurately identify any object parts that might cause interference and collisions.For this purpose,specific pairs of faces belonging to any of the interfering objects found in the first stage are tested,thus performing detailed computation on a reduced amount of data. Experimental results,which demonstrate the efficiency of the proposed collision detection method are given.

This study aimed at assessing the effects of block play on salivary alpha-amylase activity (sAMY) in children who lived in affected or less affected area by the 2011 Great East Japan Earthquake. The experimental group was thirty-six 5-year-old children who lived in the affected area by the tsunami, and the control group was thirty-five 5-year-old children who lived in the less affected area. The participants played with blocks in unstructured playtime. The mean sAMY values of the experimental group and the control group were 31.1 and 31.4, respectively, before the playtime, but they were 41.4 and 24.1, respectively, after the playtime. A two-way mixed ANOVA was performed for the mean sAMY value with time of sampling as the within-subject factor and residential area as between subject factor. There was significant interaction between time of sampling and residential area. The results indicate that block play might reduce the stress-related anxiety of the children in less affected area.

After a catastrophe, accidents and incidents, PTSD and stress due to such the experience is manifestation as human emotion. Such emotions are generally sensed by sweating, heart rate, and amylase. There are a number of those using the physiological indices like those, they take a time to measure, and require installations of the equipment and burdens for young children. In this study, we develop a block shaped UI named AssessBlock with built-in sensor and a microprocessor, and uses this as a plaything of building blocks play. It is possible to record the children’s interaction with the blocks and analyze children’s emotion, without being aware of the sensing, without wearing any devices. We aim to establish a technology that can be applied to the assessment and treatment of PTSD with analyzing acquired data.

This study aimed at assessing the stress-reducing effects of block play. The experimental group was younger children affected by the tsunami and the control group was younger children not affected by the tsunami. Before and after the playtime, their salivary alpha-amylase activity (sAMY) was measured. Operational definition of block play was to manipulate the blocks in such a way as to conform to or explore one’s own conceptions in the process. Four of the 17 children in the experimental group and 11 of the 17 children in the control group engaged in block play meeting the operational definition (Fisher’s exact test, p=.0366). sAMY decreased in 10 of the 15 participants who met the operational definition of block play. sAMY did not decrease in 23 of the 24 participants who did not meet the operational definition (Fisher’s exact test, p=.0002). The results suggested that qualitative differences in block play may affect children’s post-play stress state.

The assessment of cognitive spatial and constructional ability is an important clinical tool in the diagnosis and monitoring of brain disease or injury. It is also indispensable in scientific study of cognitive brain function. Techniques for assessment include asking patients or participants to perform purely cognitive tasks such as mental rotation, as well as constructional tasks involving arrangement of blocks and puzzle pieces into a target configuration. These constructional tasks have the advantage of probing not only pure spatial ability, but also the ability to perceive, plan, and act in the world. Studies suggest that assessment with three-dimensional (3D) forms of these tasks may be most demanding and sensitive. However, use of 3D tasks in assessment has been limited by their inherent complexity, which requires considerable examiner training, effort and time if scoring is to consistent and reliable. To overcome the limitations of existing 3D spatial cognitive assessments, we designed an automated tool for examination of 3D spatial cognitive ability. As a prototype of this user interface, we implemented by use of ActiveCube. In the evaluation, users attempt to construct a target 3D shape, while each change of shape they make is automatically recorded and scored for assessment. In order to evaluate this prototype system, we conducted several experiments. As a result, it is enough sensitive to distinguish subjects' cognitive and constructional abilities. Moreover, we have acquired knowledge to improve our prototype system. As a result of the comparisons between pre-experiment and post-experiment scores of mental rotation tests, our prototype user interface could improve users' 3-D spatial cognitive ability.

For an establishment of the basic human interface technology, this research proposed the object-oriented multi-modal interface which allows users to manipulate various objects by making use of user's intuition and user's senses to the full. And it was evaluated by using the interaction system that makes the virtual environment by using our proposed interface. In this research, we developed the interface which consists of special blocks as the object-oriented interface. This interface can secure consistency between real and virtual environment for realizing the user's intuition to the system directly. We measured the detailed characteristics of this interface. From this result, we made an interface for. cognitive assessment and a system which allows users to retrieve 3D object by using this interface by making use of the characteristic of our proposed interface fully. Furthermore, we developed an interaction method of natural object like tree models which have complex shapes and growth factor. This method is reconstructing data structure of tree models in accordance with user's operational intention by using two-handed manipulation. Moreover, we developed an interactive system which allows users to generate, manipulate and edit shapes of tree models based on a growth simulation.

In this research, we discussed the method of cooperative virtual reality system which harmonize the virtual objects and real world. The proposed system does not model all the real scene into the virtual world, but take it in to the system as the images. Moreover, virtual objects are generated and edited with the use of multimodal interface system. Our goal is to establish the essential technology for the proposed system. The main results are as follows : Manipulation in the virtual nature environment As a first step towards the system, in which the user is able to operate plant models inside the virtual environment freely with natural interface, we explore the method about dynamic object data reconstruction. So, we can arrange the operations of plant in order and investigate the method that is able to divide plant models according to their parts. Navigation in an enormous virtual environment We propose a manipulation technique to intuitively control the "bird's eye" overview display of an entire large-scale virtual environment in a display system that present a user with both overviews (global views) and a life-size virtual environment (local view) simultaneously. It enables efficient navigation even in enormous and complicated environments using both global and local views. The motion of the bird's eye viewpoint interlocks with the relative motion of the user's viewpoint and his/her hand, therefore, the user can control the "bird's eye" viewpoint by intuitive manipulation. Panoramic real images for real-time walk-through We proposed a method to create a realistic distant scenery in a virtual environment using panoramic real images taken by an omnidirectional stereo imaging sensor. The system can represent motion parallax following viewpoints according to user's movement.

立体画像共有型協調作業システムに関する研究と開発

More details Close

立体画像を複数人で共有し、皆で協調して作業をすることができる立体画像共有型協調作業システムを試作した。まず、CTで撮影したデータをボリュームレンダリングして立体表示し、複数人でこの3次元画像を観察して操作するシステムを試作し、評価した。具体的な応用例として、肺癌の手術支援と経過観察のための立体画像共有型協調作業システムを試作した。さらに、医療以外の応用例として、エンタテインメント向けのインタラクティブマルチメディアコンテンツを表示して体験するシステムについても検討した。加えて、複数人が対面して行う協調作業の中の人間関係についても考察し、複雑な状況下での対面型協調作業の精度と効率を高めることを目指して，新しいアイデアに基づく協調作業用ディスプレイ方式を考案した。最後に、3次元環境のみならず一般のGUI環境でも効率的で快適に作業できるインタフェースについて検討し、ターゲット予測を用いたポインティングインタフェースを考案した。
