Abstract

A method (700) and apparatus for adjusting the data presentation on the display (102) of an electronic device (100) is provided. A user touch scroll input device (101) is provided on the electronic device (100). A user then manipulates the user touch scroll input device (101) with a finger (116) or stylus to alter the presentation of data, which may include navigating a list of data elements (112) or altering the image magnification of an image (113) or the output of an on-board camera. Length of stroke, final point of user contact, direction of user motion, and an optional timer are all used to control the alteration of the data presentation. For example, a timing module (109) can initiate a timer with the user makes contact with the user touch scroll input device (101). While the timer is running, the data presentation is altered at a first rate. Once the timer expires, the data presentation is altered at a second rate.

Claims

1. A method for altering a data presentation on a display of an electronic device having a non-continuous scroll wheel, the method comprising the steps of:

detecting an initial contact position of a user'"'"'s digit or stylus along the non-continuous scroll wheel;

detecting a direction of movement of the user'"'"'s digit or stylus along the non-continuous scroll wheel; and

detecting a final contact position of the user'"'"'s digit or stylus along the non-continuous scroll wheel;

wherein when the final contact position is within a predetermined range of an end of the non-continuous scroll wheel, advancing the data presentation to an end limit corresponding to the direction of movement.

2. The method of claim 1, wherein the data presentation comprises an image, further wherein the end limit comprises one of a maximum image zoom or a minimum image zoom.

3. The method of claim 2, wherein the non-continuous scroll wheel comprises an incomplete circle, wherein the direction of movement comprises a clockwise movement, wherein the end limit comprises the maximum image zoom.

4. The method of claim 2, wherein the non-continuous scroll wheel comprises an incomplete circle, wherein the direction of movement comprises a counterclockwise movement, wherein the end limit comprises the minimum image zoom.

5. The method of claim 1, wherein the data presentation comprises a list, further wherein the end limit comprises one of a list end or a list beginning, wherein the list is arranged in accordance with a predetermined organizational key.

6. The method of claim 1, further comprising the steps of:

initiating a timer upon detecting the initial contact position of the user'"'"'s digit or stylus;

detecting expiration of the timer while the user'"'"'s digit or stylus is still in contact with the non-continuous scroll wheel;

detecting a second direction of movement of the user'"'"'s digit or stylus; and

incrementally altering the data presentation in accordance with the second direction of movement of the user'"'"'s digit or stylus.

7. A method of adjusting a data presentation on a display of an electronic device having an scroll device, the method comprising the steps of:

detecting a user contact with the scroll device;

initiating a timer;

detecting a user direction of motion along the scroll device from the user contact;

altering the data presentation at a first alteration rate in a direction corresponding with the user direction of motion prior to expiration of the timer; and

upon expiration of the timer, altering the data presentation at a second alteration rate in the direction corresponding with the user direction of motion.

8. The method of claim 7, wherein the data presentation comprises an image presented on the display.

9. The method of claim 8, wherein the step of altering the data presentation comprises changing an image magnification of one of the image presented on the display or an output of an image capture device of the electronic device.

10. The method of claim 9, wherein the first alteration rate is faster than the second alteration rate.

11. The method of claim 9, wherein the scroll device defines a partial-circle, wherein the user direction of motion comprises one of a clockwise motion of a user digit along the scroll device or a counterclockwise motion of the user digit along the scroll device.

12. The method of claim 11, wherein the direction comprises one of an increasing image magnification or a decreasing image magnification.

13. A electronic device for presenting and altering an image to a user, comprising:

a user touch scroll input device;

a processor coupled to the user touch scroll input device and configured to detect user contact and a user motion with the user touch scroll input device;

a display coupled to the processor configured to present the image; and

an image presentation module, operable with the processor, comprising;

a timing module configured to initiate a timer upon the processor detecting the user contact;

a motion direction module configured to determine a direction of the user motion; and

an image alteration module configured to alter a magnification of the image at a first rate, corresponding to the direction of the user motion, while the timer is running, and to alter the magnification of the image at a second rate, corresponding to the direction of the user motion, when the timer expires.

14. The electronic device of claim 13, wherein the user touch scroll input device comprises a non-continuous, curved surface having a first end and a second end, wherein when the processor detects the user contact at one of the first end or the second end, the image alteration module is configured to alter the magnification of the image to one of a maximum magnification or a minimum magnification.

15. The electronic device of claim 13, wherein when the direction of the user motion comprises a clockwise motion, the image alteration module is configured to increase the magnification of the image, further wherein when the direction of the user motion comprises a counterclockwise motion, the image alteration module is configured to decrease the magnification of the image.

16. The electronic device of claim 13, wherein the image alteration module is configured to alter the magnification of the image until the processor determines that the user contact has terminated.

17. The electronic device of claim 16, wherein the timing module is configured to reset when the user contact has terminated.

18. The electronic device of claim 13, wherein the image alteration module is configured to alter the magnification of the image by an amount that is proportional with a distance of the motion along the user touch scroll input device.

19. The electronic device of claim 13, wherein the electronic device further comprises a memory device, wherein the image comprises a stored image from the memory device.

20. The electronic device of claim 13, wherein the electronic device further comprises an image capture device having an output, wherein the image comprises an output from the image capture device.
