Abstract

Abstract:

Most existing hand tracking systems have restrictions on human motion. This paper presents a wireless, wearable, and unobstructive wrist-finger tracking system, which uses a small magnet affixed on each fingernail as a position marker and a set of small magnetic sensors attached to an electronic wristband as a detector array. As the wrist and the finger move, the combined magnetic field from all magnets is detected by each sensor at a specific wrist location. The detected data are fed into a hand posture estimator to inversely calculate the hand posture based on a mathematical system model. The measurability and trackability of hand movements in the system are validated, respectively, by measurement and hand tracking experiments.

Key words: human computer interaction, hand movements, permanent magnets
