Abstract

The present invention provides a hand-held device including a split touch sensitive input surface, the touch sensitive input surface including a first touch sensitive array, which has a position sensor adapted for detecting a relative position of a first pointer device, and a second touch sensitive array which has a position sensor adapted for detecting a relative position of a second pointer device. The second touch sensitive array is separate from the first touch sensitive array and is located on a common side with the first touch sensitive array. The hand-held device further includes a display visible from an exterior surface of the device, which is different from the exterior side interface surface where the first touch sensitive array and the second touch sensitive array are located, where the current relative position of an end of a respective pointer interacting with each of the first touch sensitive array and the second touch sensitive array are illustrated on respective display areas of the display by a display controller coupled to the first touch sensitive array, the second touch sensitive array, and the display.

Claims

1. A hand-held device including:

a split touch sensitive input surface comprising;

a first touch sensitive array including a position sensor adapted for detecting a relative position of a first pointer device located on an exterior side interface surface of the hand-held device; and

a second touch sensitive array separate from the first touch sensitive array, and commonly located on the same exterior side interface surface of the hand-held device with the first touch sensitive array, the second touch sensitive array including a position sensor adapted for detecting a relative position of a second pointer device; and

a display visible from an exterior surface of the device, which is different from the exterior side interface surface where the first touch sensitive array and the second touch sensitive array are located;

wherein the current relative position of an end of a respective pointer interacting with each of the first touch sensitive array and the second touch sensitive array are illustrated on respective display areas of the display by a display controller coupled to the first touch sensitive array, the second touch sensitive array, and the display; and

wherein a portion of each of the respective display areas of the display overlap, thereby creating a virtual overlapping zone of interaction, that does not correspond to any actual overlapping of the first touch sensitive array relative to the second touch sensitive array but that is commonly accessible through an interaction a portion of each of the first touch sensitive array and the second touch sensitive array.

2. A hand-held device in accordance with claim 1, wherein the common exterior interface surface where the first touch sensitive array and the second touch sensitive array are located is on the opposite side of the exterior surface of the device from which the display is visible.

3. A hand-held device in accordance with claim 2, wherein the first touch sensitive array has a first edge positioned proximate a right side edge of the hand-held device, the right side edge being adapted to be gripped by a right hand of a user.

4. A hand-held device in accordance with claim 3, wherein the first touch sensitive array has a second edge opposite the first edge that is positioned away from the right side edge of the hand-held device toward the center of the common exterior surface.

5. A hand-held device in accordance with claim 3, wherein the first pointer device is a finger of the right hand of the user adapted to grip the right side edge of the hand-held device.

6. A hand-held device in accordance with claim 1, wherein the relative position of the first pointer device and the second pointer device illustrated on the display is adapted to enable the user to interact with elements illustrated on the display.

7. A hand-held device in accordance with claim 1, wherein the second touch sensitive array has a first edge positioned proximate a left side edge of the hand-held device, the left side edge being adapted to be gripped by a left hand of a user.

8. A hand-held device in accordance with claim 7, wherein the second touch sensitive array has a second edge opposite the first edge that is positioned away from the left side edge of the hand-held device toward the center of the common exterior surface.

9. A hand-held device in accordance with claim 7, wherein the second pointer device is a finger of the left hand of the user adapted to grip the left side edge of the hand-held device.

10. A hand-held device in accordance with claim 1, wherein the hand-held device is a radio telephone.

11. A hand-held device in accordance with claim 1, wherein the first touch sensitive array and the second touch sensitive array are adapted to simultaneously detect the relative position of the respective first pointer device and the second pointer device.

12. A hand-held device in accordance with claim 1, wherein each of the first touch sensitive array and the second touch sensitive array includes a plurality of detectable positions along the exterior side interface surface in each of a first direction and a second direction, where the second direction is substantially orthogonal to the first direction.

13. A split touch sensitive input surface comprising:

a first touch sensitive array including a position sensor adapted for detecting a relative position of a first pointer device; and

a second touch sensitive array separate from the first touch sensitive array, and located on a common side with the first touch sensitive array, the second touch sensitive array including a position sensor adapted for detecting a relative position of a second pointer device; and

wherein at least one of the first touch sensitive array or the second touch sensitive array includes a force sensor adapted for detecting the relative force the corresponding one of the first pointer device or the second pointer device is engaging the respective touch sensitive array.

14. A hand-held device comprising:

a split touch sensitive input surface coupled to the controller including

a first touch sensitive array including a position sensor adapted for detecting a relative position of a first pointer device, and

a second touch sensitive array separate from the first touch sensitive array, and located on a common side with the first touch sensitive array, the second touch sensitive array including a position sensor adapted for detecting a relative position of a second pointer device;

a display visible from an exterior surface of the device, which is different from the exterior side interface surface where the first touch sensitive array and the second touch sensitive array are located;

wherein the current relative position of an end of a respective pointer interacting with each of the first touch sensitive array and the second touch sensitive array are illustrated on respective display areas of the display by a display controller coupled to the first touch sensitive array, the second touch sensitive array, and the display; and

wherein a boundary of each of the respective display areas corresponding to each of the first touch sensitive array and the second touch sensitive array can be separately mapped and adjusted to a particular portion of the display, and can have a different scaling factor.

15. A hand-held device in accordance with claim 14, wherein during the operation of the hand-held device a controller is adapted to change the boundary of the respective display area corresponding to each of the first touch sensitive array and the second touch sensitive array.

16. A hand-held device in accordance with claim 15, wherein when the boundary of the respective display area is changed, the controller is adapted to adjust the scaling of the translated movement of a pointer on the first touch sensitive array and the second touch sensitive array, and the relative movement mapped to the respective display area.

17. A hand-held device in accordance with claim 14, wherein the hand-held device is a wireless communication device additionally comprising:

an antenna;

a wireless interface circuit coupled to the antenna, the wireless interface circuit including at least one of a receiver, a transmitter or a transceiver; and

a controller coupled to the wireless interface circuit.
