A ring-shaped EMG measurement system for applying to user interface

This paper proposes a ring-shaped EMG measurement system to be worn on one or more fingers for a new user interface that relies on EMG measurements. A preamplifier is mounted on each electrode to suppress the effect of noise. The system is truly wearable since the main amplifier is designed to be worn on the wrist. The proposed EMG measurement system is implemented and evaluated. The experiments confirm that the proposed electrode is superior to conventional electrodes in terms of stability and usability while offering excellent long term performance. The effectiveness of the proposed electrode system is confirmed by the test in which the interface realizes highly accurate speech recognition via EMG.
