We address human factors and technology issues for the design of stereoscopic display systems that are natural and comfortable to view. Our title “just enough reality” hints at the contrast between the popularly perceived requirements for strict “virtual reality” and the expert’s pragmatic acceptance of “sufficient reality” to satisfy the human interface(More)
Many traditional designs consist of some geometrical properties of symmetry, periodicity/repetition, recursion or cycle with an endless stroke, especially in Tamil Kolam, Celtic knots, African Sona, Vanuatu Nitus, Arabesque or Asian knot etc. People like to feel infinity, recurrency and dynamism especially of trace animation in these cycle patterns, and are(More)
The Stereoscopic Haptic Acoustic Real-Time Computer (SHARC) is a multi-sensory computer system which integrates technologies for autostereoscopic display, acoustic sensing and rendering, and haptic interfaces into the same computing environment. This paper describes the system organization and the interface between diierent sensory components. This paper(More)
Using Java as the implementation language and the Netscape Communicator package, a client/server environment is established to allow requests from client stations to download the selected virtual environment to be run on the client. Various security measures, such as certiication, are included in the environment to ensure proper transfer of les and data(More)
Virtual environments can be useful in many applications. For one, they allow designers to carry out design tasks without actually creating a physical prototype. This virtual prototyping approach leads to lower cost and a shorter time-to-market product development cycle. In order for virtual environments to be useful, it must include and integrate a variety(More)
