This application is related to U.S. patent application Ser. No. 11/129,164 titled “Sign Based Human-Machine Interaction” filed on May 12, 2005 by Fujimura et al. and published as U.S. Patent Application Publication No. 2005/0271279, which is incorporated herein by reference in its entirety.
1. Field of the Invention
The present invention relates generally to human-machine interaction, and more particularly to recognizing hand signs in sign language.
2. Description of Background Art
With the advent of super-fast computing systems and highly efficient digital imaging systems, the field of computer vision based man-machine interaction has undergone a period of significant technological advancements. From simple motion detection systems where motion triggers a response from a machine (e.g., surveillance systems) to highly complex three-dimensional (“3D”) imaging sign recognition systems have been the subject of significant development in the last few years. For example, in the area of sign based human-machine commun ...
