Swing analysis of body-parts motion accompanied by apparent movement

Abstract

In this research, we examined the tactile sense for sensory substitution in people who have lost one sense. We considered the use of apparent movement to communicate something via the tactile sense. It is necessary to measure the apparent movement objectively and quantitatively because apparent movement is normally a subjective thing. We extracted swing motion, a vital reaction characteristic accompanied by apparent movement, by using electromyography (EMG). We presented individual stimuli and performed a t-test with a combination of the stimuli presented. From the t-test results, the difference in the vital reaction characteristic for each combination of stimuli presented was not small. The result presented here was obtained using only one subject, and therefore it will be necessary to increase the number of subjects in future.
