Abstract

The FingerMouse is a gumstick-sized (43 mm times 18 mm) visual input system for wearable computers. Worn on the body, the system captures the user´s hand and outputs in real-time the coordinates as well as a 1-bit image of the hand segmented from a (moving) background. It integrates cameras and vision processing using a custom designed FingerMouse-ASIC, processing images at 20 GOp/s, using only 78 mW power. This paper describes how the architecture of the FingerMouse outperforms PC-based implementations in efficiency and latency, while operating under strict size and power consumption constraints.
