This paper presents work carried out for a project to develop a new interactive technique that combines haptic sensation with computer graphics. The project has two goals. The first is to provide users with a spatially continuous surface on which they can effectively touch an image using any part

, and has potential to be a practically useful tool for graphics applications. 1 Introduction Computer renderings of objects with surface texture are more interesting and realistic than those without texture. Texture mapping [15] is a technique for adding the appearance of surface detail by wrapping

Integrating force feedback with a complete real-time virtual environment system presents problems which are more difficult than those encountered in building simpler force-feedback systems. In particular, lengthy computations for graphics or simulation require a decoupling of the haptic servo loop

This paper describes preliminary work in a project to add force feedback to user interface elements of the X Window System in an attempt to add true "feel" to the window system's "look and feel". Additions include adding ridges around icons and menu items to aid interaction

’s easier and faster to position an object against a constraining surface. 1 Such considerations have lead researchers to add physical props to virtual environments. 2 For example, Lindeman et al. added a paddle that users physically held in their left hand and saw in the virtual environment as a

The goal of this project is to automatically synthesise contact sounds that can be easily added to existing and future haptic applications without the need for extensive sound design, sampling or programming. Contact sounds are caused by interactions with objects such as scraping a surface

that consists of two projectors with two horizontally and vertically polarizing filters, and the Disney projection screen. Our system has a distributed rendering architecture where a server computer is dedicated to haptic interaction force rendering and client computers are dedicated to a visual rendering

be added and enlarge the range of haptic perception of a virtual environment. This paper is an extension of [1].

Texture mapping is a popular rendering technique used in three-dimensional computer graphics. It allows textures represented as digital images to be mapped across surfaces in a 3D scene, providing a simple method for adding realistic detail to computer generated imagery. The process of transforming

-of-the-art algorithms, but in most cases the interaction part is limited to 2D mouse/keyboard, despite the tasks being highly 3D oriented. This project involves interactive medical image visualization and segmentation, where true 3D interaction is obtained with stereo graphics and haptic feedback. Well-known image
