Abstract

Disclosed are methods and apparatus, which enable the reconfigurable control of vehicles, homes, computers and other applications. Physical controls and virtual displayed controls on single and multipoint touch screens are used, separately or in combination to enable higher visibility and understanding of control information and easier operation of controls, particularly useful in stressful situations. Some embodiments use optical sensors and rear projection of displayed embodiments, and are advantageous where curved screens are desired such as in a car.

Claims

1. A touch interface comprising:

a touch screen having a touch input area and a first relief detail on the touch input area, the touch screen being adapted to detect a touch input on the touch input area; and

a transducer adapted to vibrate the touch screen with a first force feedback signal in response to a touch input on the touch input area proximate the first relief detail.

2. The touch interface of claim 1 wherein the first relief detail defines a location to receive tactile data via the first force feedback signal.

3. The touch interface of claim 1 wherein the touch screen includes a touch sensor having at least one of a resistive touch sensor, a capacitive touch sensor, and an electro-optical touch sensor.

4. The touch interface of claim 1 wherein the touch screen is operable to display visually observable data.
