Development and evaluation of interface using masseter muscle potential and head posture

IoT has been rapidly spreading in recent years. In particular, the spread of IoT to the socially vulnerable is expected to realize advanced social inclusion. However, it is difficult for the physically handicapped people to operate the IT terminal. In this research, we developed a pointing device that does not require limb movement. In this device, the cursor is operated by swinging the head, and the click is operated by surface-EMG. Moreover, pointing performance was evaluated according to ISO 9241-9. Experimental results show that the Throughput value is about 1.5 bits/sec and has pointing performance according to the remote mouse for presentation. In addition, the malfunction rate was different among individuals. This cause is presumed to be due to individual differences in occlusion, suppressing malfunction by training is expected. From these result, it is expected that the device will be useful as a pointing device for physically handicapped people.
