Abstract

A touch sensor controller system for use in a vehicle of the type utilizing a software application to be interfaced with by an operator of the vehicle includes a touch sensor and a touch detector associated with the touch sensor. A touch gesture processor is provided which prevents unwanted or unintended touch gestures from being communicated to the application software during certain operating conditions of the vehicle. The touch gesture processor receives inputs of the operating conditions of the vehicle and receives touch gesture information from the touch detector, and the touch gesture processor is operative to determine the types of touch gestures to be permitted to be passed to the software application.

Claims

1. A touch sensor controller system for use in a vehicle of the type utilizing a software application to be interfaced with by an operator of the vehicle, the touch sensor controller system comprising:

a touch sensor;

a touch detector associated with the touch sensor; and

a touch gesture processor which receives inputs of the operating conditions of the vehicle and which receives touch gesture information from the touch detector, wherein the touch gesture processor is operative to determine the types of touch gestures to be permitted to be passed to the software application, whereby the touch sensor controller system is adapted to prevent types of touch gestures which are unwanted or unintended during certain operating conditions of the vehicle from being communicated to the application software during those certain operating conditions, wherein the operating conditions include vehicular conditions and environmental conditions, and wherein when the operating conditions indicate movement of the vehicle, the types of touch gestures permitted to be passed to the software application are limited to tap and/or tap and hold gestures.

2. The touch sensor controller system as claimed in claim 1 wherein operating conditions that trigger filtering or limiting of the touch gestures forwarded to the application software include forward movement of the vehicle, rapid movement of the vehicle, braking, acceleration, lateral cornering, rough or bumpy movement, and placing the vehicle into a mode in preparation for movement.

3. The touch sensor controller system as claimed in claim 1 wherein the vehicle is an automobile.

4. The touch sensor controller system as claimed in claim 1 wherein the vehicle is an airplane.

5. The touch sensor controller system as claimed in claim 1 wherein the vehicle is a boat.

8. The touch controller system of claim 1, wherein when an operating condition of the vehicle exceeds a threshold, the touch gesture processor prevents all touch gestures from being communicated to the application software.

9. The touch controller system of claim 4, wherein when the operating conditions of the airplane indicate the presence of turbulence above a set threshold, the touch gesture processor prevents all touch gestures from being communicated to the application software.

10. The touch sensor controller system of claim 3, wherein the inputs of the operating conditions include signals which indicate when the automobile is parked, when the automobile is in gear, and when the automobile is moving.

11. The touch sensor controller system of claim 4, wherein the inputs of the operating conditions include signals which indicate when the airplane is on the ground and when conditions in which the airplane is in the air.

6. A touch sensor controller system for use in a vehicle of the type utilizing a software application to be interfaced with by an operator of the vehicle, the touch sensor controller system comprising:

a touch sensor;

a touch detector associated with the touch sensor; and

a touch gesture processor which prevents certain types of touch gestures, which are unwanted or unintended, from being communicated to the application software during certain operating conditions of the vehicle, wherein the operating conditions include vehicular conditions and environmental conditions, and wherein when the operating conditions indicate movement of the vehicle, the touch gesture processor restricts the types of touch gestures that are passed to the application software to tap and/or tap and hold gestures.

7. The touch sensor controller system as claimed in claim 6 wherein the touch gesture processor receives inputs of the operating conditions of the vehicle and receives touch gesture information from the touch detector, and wherein the touch gesture processor is operative to determine the types of touch gestures to be permitted to be passed to the software application based on the operating conditions.
