A prototype of gesture-based interface

Abstract

This paper introduces a novel gesture-based human-machine interface prototype, which consists of a wearable belt embedding with four surface electromyography (SEMG) sensors, a tri-axis accelerometer and an application program running on NOKIA 5800XM. The sensor belt captures hand gestures by acquiring SEMG and acceleration (ACC) signals from forearm, and sends the m out via Bluetooth. The application program receives the data and translates them into control commands of a given interaction application. Experimental results of two test schemes conducted on hand gesture recognition and media player operation demonstrate the validity of the proposed gesture-based interface prototype.
