Abstract 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 compared 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.
