Transfer of Synchronized Signal using Haptic Interface

We propose a method for using a haptic interface for vision or hearing to present alternative information to a disabled person. Till date, an acceleration sensor, wireless transfer equipment, and equipment using a vibration device have been developed. This paper describes the transfer of information, employing the characteristic efficiently, using a linear vibration actuator as the vibration device. The objective is to transmit the accent of the first beat of an important rhythm by music. In this study, a method for combining two vibration frequencies and its dependence on a vibration pattern are verified by experiment. Consequently, a method depending on a vibration pattern is adopted, the verification experiment is conducted, and the same characteristic as the case where vision is used is acquired.
