Combined Force Display System of EMG Sensor for Interactive Performance

This is a report of research and some experimental applications of human-computer interaction in computer music and interactive media arts. In general, many sensors are used for the interactive communication as interfaces, and the performer receives the output of the system via graphics, sounds and physical reactions of interfaces like musical instruments. I have produced many types of interfaces, not only with mechanical/electrical sensors but also with biological/physiological sensors. This paper is intended as an investigation of some special approaches: (1) 16-channel electromyogram sensing system called "MiniBioMuse-III" and its applications, (2) 8-channel electric-feedback system and its applications, (3) combination of EMG sensor and biofeedback system sharing same electrode to construct the "force display" effect of live control with EMG sensors.
