                                ABSTRACT:

We describe a system that can track a hand in a sequence of video frames and
recognize hand gestures in a user-independent manner. The system locates the
hand in each video frame and determines if the hand is open or closed. The
tracking system is able to track the hand to within 10 pixels of its correct
location in 99.7% of the frames from a test set containing video sequences
from 18 different individuals captured in 18 different room environments. The
gesture recognition network correctly determines if the hand being tracked is
open or closed in 99.1% of the frames in this test set. The system has been
designed to operate in real time with existing hardware.
