The appeal of computer games may be enhanced by vision-based user inputs. The high speed and low cost requirements for near-term, mass-market game applications make system design challenging. The response time of the vision interface should be less than a video frame time and the interface should cost less than 50 Dollars U.S. We meet these constraints with algorithms tailored to particular hardware. We have developed a special detector, called the artificial retina chip, which allows for fast, on-chip image processing. We describe two algorithms, based on image moments and orientation histograms, which exploit the capabilities of the chip to provide interactive response to the player's hand or body positions at 10 msec frame time and at low-cost. We show several possible game interactions.2nd International Conference on Automatic Face and Gesture Recognition, Killington, VT, USA This work may not be copied or reproduced in whole or in part for any commercial purpose.

The results of recent research on our implantable CMOS biomedical devices are reviewed. Topics include retinal prosthesis devices and deep-brain implantation devices for small animals. Fundamental device structures and characteristics as well as in vivo experiments are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
