Patent ID: 6965842

Claim:
A user input apparatus that is used by attaching to a human body, the user input apparatus being characterized by comprising: a plurality of transmission electrodes; a plurality of reception electrodes; a human body attaching means for attaching the transmission electrodes and reception electrodes alternately along a surface of the human body; a signal generator for supplying a waveform signal of a predetermined frequency to each of the transmission electrodes; and a receiver for receiving a waveform signal to be received at each of the reception electrodes, wherein the user input apparatus comprises measurement means for measuring a gesture of a user with the plurality of transmission electrodes and the plurality of reception electrodes by using a change in a static capacity of a capacitor that is formed between the transmission electrode and the reception electrode and the surface of the human body, and for detecting results of the measurement as a multi-dimensional vector value, wherein values of respective dimensions of the multi-dimensional vector value correspond to respective pairs of the transmission electrodes and the reception electrodes, the pairs being different from each others.
