Abstract

The human hands are the major means through which we gain our primary connection to the world. The modeling of human hands is a very important issue in virtual environments, however little research has been done to support higher levels of abstraction of using hands beyond that of just capturing raw data.

In this paper we present an alternative view of hand modeling, i.e., a point-based hand model, and then investigate 3D static hand gestures in detail. Thereby, we develop a device-independent and general-purpose logical hand device, which supports the use of comprehensive 3D gestural input in virtual environments. Based on our logical hand device, not only can the implementation of ``point, reach, and grab'' interaction be facilitated, but also American-Sign-Language-like static gestures can be conceived easily.
