A step towards multi-level human interface devices: a system that responds to EEG/SEMG triggers

Abstract

This project forms the basis of our wider project scope which is to develop a multi-level interface device, which can increase the levels of interaction at the human machine interface (HMI). This paper describes the work done so far to establish a viable, practical, low equipment and low computation cost system which is responsive to electroencephalogram-surface electromyogram (EEG-SEMG) triggers. The system consists of the user required to perform tasks for our system to achieve four states of switching. The system then uses this as a trigger in order to help the user operate everyday equipment. It is intended that the device can be worn or carried around easily, whether the person is able-bodied or disabled. The setup of the equipment, the process of the experiments, the types of mental tasks that the user was required to perform, signal processing and corresponding trigger output commands that were generated are described.
