Design Exploration of a Human-machine Interface Application
Francis Li, Samuel R. Madden · 2000
A data glove is a human-machine interface designed to capture the motion of a computer operator's hand for realtime input. Current implementations of such devices are commonly bulky, wired, and have high power requirements. It has been proposed that a data glove could be implemented with low power, integrated sensing and processing components with wireless communications. In this paper, we evaluate an existing lower-power data-glove implementation. Then, with minimizing power requirements as a goal, we evaluate design alternatives that tradeoff application specific local processing with communication. Finally, we compare the performance of those software alternatives on several general purpose microcontrollers and DSPs.

Both existing and new applications are being developed that take advantage of a rapidly ...
