ABSTRACT:
In order to provide an active muscle display unit that extracts a firing pattern of the individual motor unit without applying a load to living organisms and display the extracted motor unit, the active muscle display unit comprises multiple electrodes that are arranged on a skin surface, a surface electromyogram measuring part that measures a surface electromyogram on the skin surface at the multiple electrodes, a motor unit separating part that estimates the individual motor unit constituting an active muscle based on the surface electromyogram measured by the surface electromyogram measuring part, a motor unit position estimating part that estimates a three-dimensional position of the firing motor unit based on the motor unit estimated to be the firing motor unit by the motor unit separating part, and a display part that displays the motor unit estimated by the motor unit position estimating part in an image.
