This paper describes the development and evaluation of a tactile hybrid interface of verbal and nonverbal communication, which informs Deaf-Blind people of their position and direction in real-time through the tactile sensation by Finger-Braille method. Finger-Braille is one of the great commonly used communication methods among the Deaf-Blind people in Japan. We psychologically show the subjects felt tactile stimulation transmitting by the interface as simultaneous stimulation, by measuring delay of stimulus signal between both hands caused by wireless connection and time discrimination threshold of both hands. We propose a new wayfinding system using the combination of verbal and nonverbal information using the proposed interface, and verify the feasibility of instructing the correct orientation by using tactile stimulation pattern through experiments.
