Abstract
A touch-sensitive input device provides improved visual feedback at (or near) the point and time of contact. As the user touches a touch-sensitive screen or pad, a portion of the screen or pad changes in visual appearance to indicate that the input has been received. In one embodiment, the change in visual appearance is localized to an area proximate to the point of contact. In one embodiment, the change in visual appearance is accomplished by illuminating an area proximate to and centered around the point of contact. In another embodiment, the change in visual appearance is accomplished by illuminating one or more illuminable elements, such as light-emitting diodes (LEDs) on the touch-sensitive pad.
