sense based controller / controller

'Sense based controller' is a universal controller for blind people. Blind people have difficulty controlling home appliances in their daily lives.
Most of the controllers or products have too many buttons or a touchscreen. So we designed a controller that uses sense of touch, which is the strength of the blind people. User can control products more easily using senses such as touch and hearing. Unlike other controllers, the controller can be used through sense, making it easy for blind people to control it.
