A Communication Aid for Deaf-Blind Person Using Vibration Motors : Phase Control of Vibration Motor

Abstract

This paper proposes a communication aid for deaf-blind and visually disabled persons. The aid is constructed with six motors and seven switches. It enables the disabled to indicate a braille by using stimulus of vibration motor. Thus, the disabled are able to input a braille at the same position by pushing the switches. To search for a fit stimulus level of this aid, we experimented with vibration at the their fingers. It was found the effective method for this aid to group the structure and the phase control by stimulus points.
