The Feeling Mouse

Mouse designs should be made not only focusing the sound but also it should let user feel the 'click'. Designer Si Hun Lee designed the 'Feeling Mouse', designed specifically for the hearing impaired, appeals to the user’s tactile senses to emphasize the all-important “click” that’s crucial in operating the device. When the user presses down on the mouse, raised bumps slightly protrude through designated holes where the user’s fingers rest to signal the “click.” It’s a simple solution, but incredibly useful for those missing out on this subtle queue.
