Recently, research has been done to develop an interface tool which makes use of " bio-response". However, due to a lack of measuring system and equipment which can be used easily, it was hoped that there would be development. The distinctive features of our method are the surface electrodes which have been glued around of forearm, and the analytical technique of signal wave. 6 surface electrodes were glued at equal distance on a single pole. As for analytical process, first, the output signals of each electrode is full wave rectified and integrated in each frequency band, and these integrated values are then added up. This figure is the intensity of musculo electric potential passed on the position of each electrode. Furthermore, the musculo electric potential of each point is added up. This is the quantity of musculo activity in the whole of the forearm. In this way, it was shown that the distribution of musculo electric potential around the forearm and intensity levels were readily available for tool development and rehabilitation.
