In the educational practice for hearing-impaired students, visual informations is generally used as alternative support tool of sound information. The author has studied mostly about visual information tool as well. From the results of tests with the visual information tool, the possibility of tactile device was emerged. Especially when it is required detailed maneuver or subtle timing, tactile information device was expected to be useful. We created a device which shows instructor's manipulation by tactile information in additional to visual information and the software SZCAT (SynchroniZed Click Action Transmitter). And as a basic study on the effect of the developed system, we compared the conventional method with the method adding tactile information and verified the effectiveness of tactile information presentation. As a result, we were able to confirm the effect of reducing gaze movement due to the addition of tactile information, and the effect of reducing misrecognition of teaching contents.
