The paper introduces the development of a tactile device using a shape-memory alloy, and describes the information transmission by the higher-level perception such as the apparent movement and phantom sensation of the tactility. The authors paid attention to the characteristic of a shape-memory alloy formed into a thread, which changes its length according to its temperature, and developed a vibration-generating actuator electrically driven by periodic signals generated by current control circuits, for the tactile information transmission. By coupling the devices as a pair, an information transmission system was constructed for presenting the apparent movement of the tactility, to transmit quite novel sensation to a user. The information transmission by the device was tested by 10 subjects, and evaluated by questionnaires. The apparent movement was especially well perceived by users as a sensation of something running across fingers or as being tapped by something, according to the difference of signals given to the devices. Several users reported the rubbing sensation given by the AM, and we further experimented the presentation of the sensation in detail.
