Abstract
A touch sensitive apparatus and method of operation to improve visual feedback and visual perception of tactile input to an operator. The apparatus includes a touch screen device or display having a touch overlay, a processor and stored program instructions in a memory in which a three-dimensional graphical image, such as a key element, is created in the apparatus and shown on the display as an input device or keypad to the processor. Each key element includes a beveled surface surrounding a flat surface. When a displayed key element is touched by a probe, such as a finger, the screen area about the displayed key element and the finger, visually enlarges or “splats” confirming the selection of the particular key. Concomitantly or simultaneously, the key element detents or depresses within the key pad, changes color and bevel size further verifying the key selection to the operator thereby creating a sense of key movement and visual perception of tactile input to the operator aiding in the operation of the key pad. The simultaneous visual key enlargement, visual detenting and change in key color and bevel size upon key selection in a touch sensitive apparatus improves the feedback to the operator in the selection and confirmation of a key element actuated by the operator.
