Abstract

A visual feedback system includes a touch input screen. A proximity sensing device is coupled to the touch input screen and operable to determine a position of an input member relative to the touch input screen when the input member is proximate to the touch input screen but prior to the contact of the input member and the touch input screen. A visual feedback engine is coupled to the touch input screen and the proximity sensing device and is operable to receive the position of the input member from the proximity sensing device and provide a visual feedback for data displayed on the touch input screen that corresponds to the position of the input member relative to the touch input screen.

Claims

1. A visual feedback system, comprising:

a touch input screen;

a proximity sensing device that is coupled to the touch input screen, the proximity sensing device operable to determine a position of an input member relative to the touch input screen when the input member is proximate to the touch input screen but prior to the contact of the input member and the touch input screen; and

a visual feedback engine that is coupled to the touch input screen and the proximity sensing device, the visual feedback engine operable to receive the position of the input member from the proximity sensing device and provide a visual feedback for data displayed on the touch input screen that corresponds to the position of the input member relative to the touch input screen.

2. The system of claim 1, further comprising:

a display chassis, wherein the touch input screen is mounted to the display chassis and the proximity sensing device is housed within the display chassis and located adjacent the touch input screen such that the determining the position of the input member relative to the touch input screen is performed through the touch input screen.

3. The system of claim 1, further comprising:

a display chassis, wherein the touch input screen is mounted to the display chassis and the proximity sensing device is located on a surface of the display chassis such that the determining the position of the input member relative to the touch input screen is performed adjacent the touch input screen.

4. The system of claim 1, further comprising:

a visual feedback storage coupled to the visual feedback engine, wherein the visual feedback storage comprises at least one visual feedback action corresponding to data which the touch input screen is operable to display.

5. The system of claim 1, wherein the proximity sensing device is operable to determine the positions of a plurality of input members relative to the touch input screen when the plurality of input members are proximate to the touch input screen but prior to the contact of the plurality of input members and the touch input screen.

6. The system of claim 1, wherein the visual feedback comprises enlarging the data that is displayed on the touch input screen and that corresponds to the position of the input member relative to the touch input screen.

7. The system of claim 1, wherein the visual feedback comprises changing a color of the data that is displayed on the touch input screen and that corresponds to the position of the input member relative to the touch input screen.

8. The system of claim 1, wherein the visual feedback comprises framing the data that is displayed on the touch input screen and that corresponds to the position of the input member relative to the touch input screen.

9. The system of claim 1, wherein the visual feedback comprises providing an information indicator for the data that is displayed on the touch input screen and that corresponds to the position of the input member relative to the touch input screen.

10. An information handling system, comprising:

a processor;

a storage coupled to the processor;

a display coupled to the processor and comprising a touch input screen;

a proximity sensing device that is coupled to the touch input screen, the proximity sensing device operable to determine a position of an input member relative to the touch input screen when the input member is proximate to the touch input screen but prior to the contact of the input member and the touch input screen; and

a visual feedback engine that is coupled to the touch input screen and the proximity sensing device, the visual feedback engine operable to receive the position of the input member from the proximity sensing device and provide a visual feedback for data displayed on the touch input screen that corresponds to the position of the input member relative to the touch input screen.

11. The system of claim 10, wherein the proximity sensing device is housed in a display chassis and located adjacent the touch input screen such that the determining the position of the input member relative to the touch input screen is performed through the touch input screen.

12. The system of claim 10, wherein the proximity sensing device is located on a surface of a display chassis such that the determining the position of the input member relative to the touch input screen is performed adjacent the touch input screen.

13. The system of claim 10, wherein the visual feedback engine is coupled to the storage and the storage comprises at least one visual feedback action corresponding to data which the touch input screen is operable to display.

14. The system of claim 10, wherein the proximity sensing device is operable to determine the positions of a plurality of input members relative to the touch input screen when the plurality of input members are proximate to the touch input screen but prior to the contact of the plurality of input members and the touch input screen

15. A method for providing visual feedback, comprising:

providing a touch input screen;

determining a position of an input member relative to the touch input screen when the input member is proximate to the touch input screen but prior to the contact of the input member and the touch input screen; and

providing a visual feedback for data displayed on the touch input screen that corresponds to the position of the input member relative to the touch input screen.

16. The method of claim 15, wherein the visual feedback comprises enlarging the data that is displayed on the touch input screen and that corresponds to the position of the input member relative to the touch input screen.

17. The method of claim 15, wherein the visual feedback comprises changing a color of the data that is displayed on the touch input screen and that corresponds to the position of the input member relative to the touch input screen.

18. The method of claim 15, wherein the visual feedback comprises framing the data that is displayed on the touch input screen and that corresponds to the position of the input member relative to the touch input screen.

19. The method of claim 15, wherein the visual feedback comprises providing an information indicator for the data that is displayed on the touch input screen and that corresponds to the position of the input member relative to the touch input screen.

20. The method of claim 15, wherein the visual feedback comprises simulating movement of the data that is displayed on the touch input screen and that corresponds to the position of the input member relative to the touch input screen.
