wissenschaftliches Toningenieur-Projekt

The project investigates the usability of muscle contractions detected
by surface electromyography (EMG) sensors as an input channel for the gestural,
or subtle control of electric devices. A wearable hardware prototype is
presented that consists of a sensor strap and a signal conditioning
(amplification and filtering) unit. Signal detection techniques are discussed
and an evaluation framework is presented based on signal detection theory.
Using the framework common envelope tracking techniques are compred in a user
study that uses the prototype. This work forms the basis for further research on
using EMG signals for controlling, regulation, and navigation purposes as well
as music performance.
