Abstract
We shall present some results of our research on hand tracking and
gesture recognition in the last decade. This research is motivated by
applications in human-computer interaction such as display control in
virtual environments and the manipulation of virtual objects. Although
we have studied both Appearance-Based and 3D Model-Based approaches,
this talk will concentrate on the latter.
At any given time instant, the hand configuration - 6 parameters for the
global hand "pose" and 21 finger joint angles (the hand "posture") - is
a point in the 27-dimensional configuration space. We track the
trajectory of this point over time using a 3D model-based and
analysis-by-synthesis approach. The challenge is to represent the
constraints on hand posture and finger movement in a compact way and use
this representation to speed up the search in the 21-dimensional space.
The tracking results can then be used to do gesture recognition. Some
results will be shown on constraint representation and its use in
tracking.
Short Bio
Thomas S. Huang received his B.S. Degree in Electrical Engineering from
National Taiwan University, Taipei, Taiwan, China; and his M.S. and
Sc.D. Degrees in Electrical Engineering from MIT. He was on the Faculty
of the Department of Electrical Engineering at MIT from 1963 to 1973;
and on the Faculty of the School of Electrical Engineering and Director
of its Laboratory for Information and Signal Processing at Purdue
University from 1973 to 1980. In 1980, he joined the University of
Illinois at Urbana-Champaign, where he is now William L. Everitt
Distinguished Professor of Electrical and Computer Engineering, and
Research Professor at the Coordinated Science Laboratory, and Head of
the Image Formation and Processing Group at the Beckman Institute for
Advanced Science and Technology and Co-Chair of the Institute's major
research theme Human Computer Intelligent Interaction.
Dr. Huang's professional interests lie in the broad area of information
technology, especially the transmission and processing of
multidimensional signals.
