Abstract
An electro-tactile display includes an electrode substrate provided with a plurality of stimulation electrodes, a conductive gel layer positioned between the stimulation electrodes and the skin of a wearer, a switching circuit section electrically connected to the stimulation electrodes, a stimulation pattern generating section electrically connected to the switching circuit, and means for alleviating a sensation experienced by the wearer as a result of the stimulation electrodes. In one aspect, the means for alleviating a sensation is configured from the conductive gel layer. The conductive gel layer has a resistance value equivalent to that of the horny layer of the skin. In another aspect, the means for alleviating a sensation is configured from the stimulation determination means and the threshold value adjustment means.
