A disciplined investigation of "whole-hand interfaces (often glove based, currently) and their appropriate use for the control of complex task domains is embodied by the design method for whole-hand input.This is a series of procedures-including a common basis for the description, design, and evaluation of whole-hand input, together with an accompanying taxonomy-that enumerates key issues and points for consideration in the development of whole-hand input.The method helps designers focus on task requirements, isolate problem areas, and choose appropriate whole-hand input strategies for their specified tasks.Several experiments were conducted to validate and demonstrate the use of the design method.The results of the experiments are summarized and discussed.

In this paper we describe the evolution of a whole-hand interface to our virtual-environment graphical system. We present a set of abstractions that can be used to implement device-independent interfaces for hand measurement devices. Some of these abstractions correspond to known logical device abstractions, while others take further advantage of the richness of expression in the human hand. We describe these abstractions in the context of their use in our development of virtual environments.

Specialized computer architectures can provide better price/performance for executing image processing and graphics applications than general purpose designs. Two processors are presented that use parallel SIMD data paths to support common graphics data structures as primitive operands in arithmetic expressions. A variant of the C language has been implemented to allow high level language coding of user applications on these processors. High level programming support is designed into the processor architecture that implements parallel object data typing and parallel conditional evaluation in hardware.
