The basic principle is to display appropriate images accompanied by user's interaction, using position data. For this methodology, a huge image database indexed by position data must be sampled from the real world. A prototype of a vehicle-mounted image capturing system is developed for this purpose. The relationship between image distortion and the error of sensors when applying the morphing technique to this system is also discussed. At the end of this paper, an image-based walk-through system is actually demonstrated and the potential advantages of this methodology are discussed as an example.","PeriodicalId":105542,"journal":{"name":"Proceedings.

It is shown that the mapping from displacements of the finger surface to displacements of the mechanoreceptors is a one-to-one mapping. Therefore, it is necessary to create the same displacements of the finger surface as in actual exploration for tactile virtual reality (VR). However, the mapping from shapes of objects to displacements of the finger surface is shown to be a many-to-one mapping because of the mechanical properties of skin. So, we use the envelope of the amplitude-modulated Lamb wave on an elastic plate as an alternative shape to the real object, because its shape can be easily controlled. The generation of the wave is confirmed with an experimental device of silicon rubber vibrated by voice coils.","PeriodicalId":105542,"journal":{"name":"Proceedings.

In order to lessen these burden, good mastering of data flows is required. Host information needs mostly depend on how local observers perceive the virtual world surrounding them. The authors propose a structure storing a hierarchical description of the world as a basis for host information needs identification. The information rejection criterion is currently an approximation of the projected area along an axis toward the observer on a perpendicular plane. It can be applied to sources such as visual objects or sound sources. This structure, used to dynamically reference sources based on their position and scale, is called a space scale structure (SSS); an octree is the actual storing structure. The SSS is traversed in order to retrieve sources, with respect to the rejection function. Optimizations of SSS traversal and SSS update for moving sources, based on temporal coherency, are presented. A possible distributed architecture using the SSS is also proposed. This architecture makes use of multicast and client/server network topologies. The implementation of the SSS is evaluated locally in the context of large database culling.","PeriodicalId":105542,"journal":{"name":"Proceedings.

The image data (a B/W photograph taken carefully) of surface textures proved to be compatible with the surface geometry data-a height map-by an experiment with two simple-shape real texture patches. As a raw geometry data-hence a raw image-was not suitable for the texture display, they proposed to apply a histogram transformation to make the sensation produced by the data close to the real one. They obtained two histogram transformations out of fifty, by which the geometry data were adjusted so that they could best produce texture sensations regarding six real patches. The data adjusted by the transformations proved to present appropriate sensations to novice users who compared the data and the real patches tactually.","PeriodicalId":105542,"journal":{"name":"Proceedings.

Unlike previous efforts, this design focuses on the ability of the system to dynamically configure itself without explicit user interaction, allowing applications to take on new functionality after execution. In particular, this framework facilitates the discovery of virtual environments on the network at runtime. Fundamentally, Bamboo offers a compatible set of mechanisms needed for a wide variety of real-time, networked applications. Also included is a particular combination of these mechanisms supporting a dynamically extensible runtime environment. This paper serves as a general introduction to Bamboo. It describes the system's architecture, implementation and future directions. It also shows how the system can facilitate the rapid development of robust applications by promoting code reuse via community-wide exchange.","PeriodicalId":105542,"journal":{"name":"Proceedings.

In this paper, we propose a method to display such tactile feeling of fine texture with reality. We create the feeling by selective stimulation to each kind of mechanoreceptor using the elastic transfer property of the skin. Our system is composed of four small magnet tips attached on the hand in a line, which are controlled with precise force. The two driving modes, the common phase mode and the reversed phase mode, stimulate the deep receptors and shallow receptors in the skin, respectively. The system could give several types of tactile feeling with reality. The principle and experimental results are shown.","PeriodicalId":105542,"journal":{"name":"Proceedings.
