In this paper, we explore the use of tactile apparent motion at different patterns and speeds for information displays. As the first step, we investigate stimulus conditions and the number of tactors to build information displays. As the second step, a prototype of tactor array consisting of five tactors, which is mounted on the upper arm of subjects, was constructed. In order to evaluate the system, experiments to measure the performance of users' ability to distinguish between multiple kinds of stimuli were conducted for two levels: physical level and semantic level. For the physical level, users' ability to distinguish four motion patterns at three different speeds was tested. For the semantic level, users' ability to identify four kinds of messages with three levels of importance, each of which corresponds to the combination of specific motion pattern and speed, was tested. In both experiments, users had little trouble with pattern and speed identification. Several ideas for future exploration of tactile apparent motion for general-purpose information displays are presented.
