Abstract
We have conducted experiments of operating a force operating joystick to both sound stimulus and visual stimulus. Sound stimulus is white noise that sound level fluctuates periodically. Visual stimulus is the bar which performs vertical motion periodically. These two stimuli with phase shift are given to test subjects. During an experiment, biological signal IEMG and joystick operating force are measured. We demonstrated that there is no phase shift between IEMG signal and visual stimulus when the appropriate phase shift between sound stimulus and visual stimulus are given to test subjects.
