Transmission of stroking sensation on a skin by higher-psychological perception

Humans are able to communicate with each other by using not only verbal media but also the five senses such as vision, audition, olfaction and tactility. Our emotions and feelings are directly transmitted through non-verbal media, especially tactile sensation senses the physical information about an object or an environment. We have paid attention to the information transmission through the higher-psychological perception of tactility, and are now constructing a tactile transmission system for presenting stroking sensation. This paper introduces the development of a tactile display using a shape-memory alloy, and describes the transmission of stroking sensation by the higher-psychological perception such as the phantom sensation (PS) and the apparent movement (AM) of the tactility.
