Improving the Usability of a Wearable Input Device SCURRY TM

Abstract

In this paper, a finger-click recognition method is proposed to improve the recognition performance for finger-clicking of a wearable input device, called SCURRY™. The proposed method is composed of three parts including feature extraction part, valid click discrimination part, and cross-talk avoidance part. Two types of MEMS inertial sensors are embedded into the wearable input device to measure the angular velocity of a hand (hand movement) and the acceleration rates at the ends of fingers (finger-click motion). The experiment applied to the SCURRY ™ device shows the improved stability and performance
