Abstract

A portable communication device is equipped with a touch input device configured to provide key press functionality and scrolling functionality. The touch input device is electronically defined to include a plurality of key press areas separated by grey zones. The portable communication device is configured to provide scrolling functionality in response to detection of sequential user contact with multiple key press areas and an intervening grey zone within a predetermined timing trigger.

Claims

1. A portable communication device comprising:

a housing;

a display disposed within the housing; and

at least one touch input device disposed within the housing, the touch input device being operatively coupled to touch input device control circuitry, wherein the touch input device control circuitry is configured to;

detect a key press in a first key press area of the touch key input device;

detect a key release in the first key press area;

detect a key press in a second key press area adjacent to the first key press area; and

transmit a scroll command if the key press in the second key press area is detected within a predetermined period of time relative to the key release in the first key press area.

2. The portable communication device according to claim 1, wherein the touch input device is a touch strip.

3. The portable communication device according to claim 1, wherein the touch input device control circuitry cooperates with the touch input device to define at least a first key press area and a second key press area on the touch key input device, wherein the first and second key press areas are separated by a grey zone.

4. The portable communication device according to claim 1, wherein the touch input device control circuitry cooperates with the touch input device to define a first key press area, a second key press area and a third key press area on the touch key input device, wherein the first and second key press areas are separated by a first grey zone and the second and third key press areas are separated by a second grey zone

5. The portable communication device according to claim 1, wherein the touch input device control circuitry is configured to detect a key release in the first key press area by detecting contact relative to a grey zone adjacent the first key press area.

6. The portable communication device according to claim 5, wherein the touch input device control circuitry is configured to detect a key press in a second key press area by detecting contact relative to the second key press area adjacent the grey zone.

7. The portable communication device according to claim 1, wherein the scroll command is operative to effect scrolling of an image on the display in a direction dependent on the position of the second key press area relative to the first key press area.

8. The portable communication device according to claim 7, wherein if the second key press area is disposed vertically above the first key press area, then the scroll command is operative to effect upward scrolling of the display.

9. The portable communication device according to claim 7, wherein if the second key press area is disposed vertically below the first key press area, then the scroll command is operative to effect downward scrolling of the display.

10. The portable communication device according to claim 7, wherein if the second key press area is disposed right of the first key press area, then the scroll command is operative to effect scrolling of the display to the right.

11. The portable communication device according to claim 7, wherein if the second key press area is disposed left of the first key press area, then the scroll command is operative to effect scrolling of the display to the left.

12. The portable communication device according to claim 1, wherein the touch input device is disposed on a front surface of the housing.

13. The portable communication device according to claim 1, wherein the touch input device is a strip disposed on a side surface of the housing.

14. The portable communication device according to claim 1, wherein the portable communication device is a mobile telephone.

15. A method of scrolling a display on a portable communication device, the method comprising:

detecting contact relative to a touch input device in a first key press area of the touch input device;

detecting a release of contact in the first key press area;

detecting contact relative to the touch input device in a second key press area adjacent to the first key press area; and

scrolling the display in a direction based on the relative position of the first key press area and the second key press area if contact with the second key press area is detected within a predetermined time relative to detecting release in the first key press area.

16. The method according to claim 15, further comprising:

transmitting a first key press event command in response to detecting contact relative to a touch input device in a first key press area of the touch input device; and

transmitting a first key release event command in response to detecting a release of contact in the first key press area.

17. The method according to claim 16, further comprising:

transmitting a second key press event command in response to detecting contact relative to the touch input device in a second key press area adjacent to the first key press area; and

transmitting a scroll command if detecting contact relative to the touch input device in the second key press area occurs within a predetermined time relative to detecting a release in the first key press area.

18. The method according to claim 15, wherein the touch input device is electronically segmented to include at least a first key press area and a second key press area on the touch key input device, wherein the first and second key press areas are separated by a grey zone;

and wherein detecting a release of contact in the first key press area includes detecting contact relative to the touch input device in the grey zone of the touch input device.

19. The method according to claim 15, wherein the portable communication device is a mobile telephone.
