Abstract

A user interface assembly includes a first touch sensitive pad and a second touch sensitive pad spaced apart from each other that both sense a position of corresponding objects on each touch sensitive pad and synchronizes those positions into an output that relates the sensed positions to corresponding positions on a mapped device.

Claims

1. A user interface assembly comprising:

a first touch sensitive pad that senses a position of a first object;

a second touch sensitive pad that senses a position of a second object, the second touch sensitive pad spaced apart from the first touch pad; and

a controller that synchronizes inputs from each of the first and second touch sensitive pads relative to each other on a common mapped device.

2. The user interface assembly as recited in claim 1, wherein the controller synchronizes inputs from the first and second touch sensitive pads to corresponding points on the common mapped device.

3. The user interface assembly as recited in claim 2, wherein the mapped device comprises a virtual touch pad.

4. The user interface assembly as recited in claim 1, wherein the controller generates a control output that relates the sensed position of the first and second objects to a position on a displayed image.

5. The user interface assembly as recited in claim 1, wherein at least one of the first and second touch sensitive pads includes a home region that defines a starting point corresponding to a home region on the common mapped device.

6. The user interface assembly as recited in claim 5, wherein the first and second touch sensitive pads include a visible indicator of the home region that separates the home region from surrounding regions of the first and second touch sensitive pads.

7. The user interface assembly as recited in claim 6, wherein the controller generates an output responsive to positioning of the first and second objects within the home region of each of the first and second touch sensitive pads that relates to a desired position on the mapped device.

8. The user interface assembly as recited in claim 7, wherein the controller generates an output responsive to moving the first and second objects relative to respective ones of the first and second touch sensitive pads to control modification of a displayed image.

9. The user interface assembly as recited in claim 1, wherein each of the first and second touch sensitive pads includes a respective switch that can be actuated by pressing a corresponding one of the first and second touch sensitive pads.

10. The user interface assembly as recited in claim 1, wherein the first and second objects comprise fingers on different hands of an operator.

11. The user interface as recited in claim 1, wherein the common mapped device comprises at least one display device that generates an image, where the image is controlled by outputs generated from the controller.

12. The user interface as recited in claim 11, wherein the controller synchronizes inputs from each of the first and second touch sensitive pads indicative of a sensed position of at least one of the first object and the second object and generates a control output that relates the sensed position to a position on the common mapped device.

13. The user interface as recited in claim 1, wherein at least one of the first and second touch sensitive pads are disposed within a vehicle steering wheel.

14. The user interface assembly as recited in claim 1, wherein the first and second touch sensitive pads are positioned on opposing sides a vehicle steering wheel.

15. A method of synchronizing a plurality of touch sensitive pads comprising:

sensing a first position of a first object on a first touch sensitive pad;

sensing a second position of a second object on a second touch sensitive pad spaced apart from the first touch sensitive pad; and

generating an output indicative of the first object and the second object that corresponds to locations on a mapped device responsive to receiving a first input indicative of the sensed first position of the first object on the first touch sensitive pad and a second input indicative of the sensed second position of the second object on the second touch sensitive pad.

16. The method as recited in claim 15, including the step of defining a home region in each of the first and second touch sensitive pads that corresponds to a desired position on the mapped device.

17. The method as recited in claim 15, including the step of setting the first position and the second position of the first and second objects sensed on the corresponding first and second touch sensitive pads at the desired position responsive to an initiation indication.

18. The method as recited in claim 17, wherein the initiation indication includes holding each of the first and second objects at corresponding home regions for a desired time.

19. The method as recited in claim 17, wherein each of the first and second touch sensitive pads comprises a switch responsive to a desired pressure on the corresponding first and second touch sensitive pads and the initiation indication comprises pressing the switch for each of the corresponding first and second touch sensitive pads.

20. The method as recited in claim 17, including the step of modifying an image on the mapped device responsive to moving at least one of the first and second objects away from the home position.
