    We present a system of help to the conception, creation and visualization in 3D of operation rooms in hospitals using the virtual reality. According to the type of surgery exercised, we define a better adapted solution to choose and to position surgical lights. This system can generate automatically an operating room in 3D while seizing the geometric measurements directly via a graphic interface. ... View full abstract»

    Exposure therapy is a clinical treatment based on gradual and systematic exposure of phobic people to the feared object or situation a little at a time. Through repeated rehearsals, their fear decreases little by little and they become more comfortable with the stimuli. For this purpose, we developed V-Theme Park-an immersive virtual environment, in which the patients themselves construct virtual ... View full abstract»

    After studying what is being developed in the interactive TV (iTV) field, we wanted to point out what we consider bad interface design and terrible interaction choices that the industry is currently on its way to make. In this paper, we propose new, more natural and more "interactive", approaches for iTV applications. And since we have already implemented most of them using our own distributed arc...

    The effect of improved cognition on algorithm performance and evaluation is an exciting area of research. Virtual reality is becoming increasingly popular as a tool for interacting with data and steering the optimization process, rather than simply displaying results. Constantly evolving haptic technology allows people to directly interact with digital objects and data as they do in the real world... View full abstract»

    We discuss the use of a mathematically based tool, function representation (FRep), for modeling complex 3D objects such as sculpture, showing an improved dynamically modifiable viewing and presentation. FRep uniquely allows smooth metamorphosis between structurally dissimilar objects, even with different mathematical connectivity. We apply FRep's modeling and metamorphosis capabilities to the mult... View full abstract»

    This paper proposes to clarify the popular term "virtual reality" through a historical and systematic analysis of the terms involved. Its main philosophical claims are that virtuality is itself a bonafide mode of reality, and that "virtual reality" must be understood as "things, agents and events that exist in cyberspace". These proposals resolve the incoherences found in the ordinary uses of thes... View full abstract»

    The "greenhouse effect" polemic demonstrates how cultural dispositions can isolate perceptions from physical reality. The cost of this isolation is a suspension of the perception of cause and effect. Without cause and effect, we cannot reliably link our actions to their effects on our environment. I present design considerations for a project which displays the causal relation between humans and t... View full abstract»

    Cyberspace is quickly becoming an alternative 'place' for everyday economic, cultural, and other human activities. Yet, cyberspace designers have not capitalized on the theories, experiences, and practices that have been guiding physical place-making. Rather, they have adopted the woefully inadequate 'document metaphor': instead of 'web-places' we find 'web-pages'. 3D environments that have closel... View full abstract»

The proposed system is constructed with a wearable computer and a head mounted display (HMD). A pair of cameras is attached to HMD positioned as a pair of eyes. Using the stereo measurement, the finger's postures are ca... View full abstract»

    The roles of computers, multi-media, virtual environments, and rapid prototyping in the design of abstract geometrical sculptures are explored. The techniques described in this paper are the outgrowth of a six-year collaboration between Brent Collins, a wood sculptor, and Carlo Sequin, a computer scientist. They are particularly applicable to abstract geometrical sculptures, where precisely define... View full abstract»

    Recent advance in computer hardware and Internet technology makes more realistic images affordable on our computer systems. However, the image creation by using conventional geometry modelling have limitations in terms of rendering time and image quality to be used in interactive rendering applications. Image-based rendering (IBR) technique is a good solution to reducing those limitations in such ... View full abstract»

    When a certain task exists, it is often performed by a method corresponding to the situation and the purpose from various requirements. Although there are many researches on motion planning for obstacle avoidance, there are only few researches investigated about the technique of preparing two or more motion plans corresponding to the situation and the purpose. In this study, the method which can e... View full abstract»

    Colors need to be corrected to minimize the discrepancy in the appearance of adjacent images such as in the applications of panoramic images. In this paper, we proposed a color correction technique that constructs a mapping from the registered overlapped regions based on a color histogram. Since the color histogram can reflect the overall color distribution, experiments prove that it can efficient... View full abstract»

    We focus on the communication between the human and robot. In the case of interactive communication, the first step is an eye contact. Therefore, we constructed a robot, which has eyes that work as an active vision. The eyes are always controlled to see the communicating person by using stereo camera images. We compare our proposed method with other known methods. Our system is capable to detect a... View full abstract»

    An escape-time method was introduced to generate the images of Julia and Mandelbrot sets and has been applied to visualize attractors of iterated function systems (IFS). Rendering deterministic fractal shapes by IFS escape-time methods suffer from some problems: the intersection of a ray with a fractal surface is not easy, surface normals are undefined, and the object aliases at all sampling resol...
