A tactile display using phantom sensation with apparent movement together

When two and more stimuli are arranged in the space, an illusion such as phantom sensation and apparent movement appear in the sense of touch. The foundation research to build a system for presenting two-dimensional information by using phantom sensation and apparent movement is done in this research. When apparent movement is used, information in the direction can be expressed between two elements of tactile stimulus in two-dimensional vector information. In this report, the authors propose the technique of information expression using three elements for tactile stimulus that the apparent movement is used with the phantom sensation together. By this technique, two-dimensional vector information can be expressed by three elements of tactile stimulus. © 2009 Wiley Periodicals, Inc.
