Much of the information human perceives is sensed through the visual organ. When the visual faculty has been impaired or the visual has been mask and no visual information is possible to be perceived, the aided perceiver of information is need. Now, when one looks at the products that are available in the market, the symbols and signs of product operation are almost is visual symbol, that is no help for visually impaired people, and sometime they may also harm themselves. People who lost their vision will have trouble in living, learning, and traveling. However, nowadays' development in auxiliary aid aims mainly at learning and traveling, particularly in information perception -- tactile display for computer user ( Shinohara et al. 1998), and seldom aims at living. Therefore, in this study, we intent to help to solve the living problems face by visually impaired people, particularly in how to use home electronic appliance when one's vision is lost.
Tactile and auditory faculties are the two main channels for person has relied on in receiving outside information, since the visual has been impaired or mask.
