Evaluation of Cognition of Information Which is Stimulated by the Sense of Touch Using Phantom Sensation and Apparent Movement

The use of a car navigation device by a heavy auditory handicapped person is anticipated because acquisition restriction of driver's license becomes easy. This study is aimed for development of the sense of touch navigation which assumed the use of a car navigation device by a heavy auditory handicapped person. It is occurrence by phantom sensation to tactile perception with the tactile motor of the Flatness type and the core is unbalanced which attached to the both ears back, and we tried transmission of position information. The result of having compared an occurrence position by the vibration strength ratio with a recognition occurrence position by phantom sensation, high correlation was provided in all subjects. In addition, we evaluated performance as a presentation method. The resolving power that could show Phantom Sensation by a vibration motor was 6 from 4. As result, possibility of transmission of right and left direction information was suggested.
