Abstract

An input device for use with computer systems is provided. In one example, an input device includes a touch-sensitive screen and an overlay positioned over the touch-sensitive screen, the overlay having a plurality of tactile features. The touch-sensitive screen is operable to display one or more images, e.g., of multiple keyboard configurations, character sets, or other control functions, to facilitate input to a computer system. The image may be varied to provide a multi-configurable input device. Additionally, the tactile features may include transparent extruded areas, such as ridges, molded key features, indentations, protrusions or the like arranged to provide users with a tactile feel (e.g., for motion and/or location) of varying portions of the underlying displayed image.

Claims

1. An input device operable with a computer system, the input device comprising:

a touch-sensitive screen; and

an overlay positioned over the touch-sensitive screen, the overlay having a plurality of tactile features.

2. The input device of claim 1, wherein each of the plurality of tactile features includes an extruded area.

3. The input device of claim 2, wherein at least a portion of each of the extruded areas is operable to touch the screen in response to a force applied to the extruded area toward the touch-sensitive screen.

4. The input device of claim 2, wherein the extruded areas include one of a protrusions, ridge, or indentation.

5. The input device of claim 1, wherein the touch-sensitive screen is operable to generate a coordinate location value in response to touching of the screen.

6. The input device of claim 1, wherein the touch-sensitive screen is operable to display at least two different images associated with the position of the plurality of tactile areas.

7. The input device of claim 1, wherein the touch-sensitive screen is operable to display at least two different images associated with two different keyboard configurations.

8. The input device of claim 1, wherein the touch-sensitive screen includes a first portion associated with the overlay and plurality of tactile features, and a second area associated with a display area.

9. The input device of claim 1, wherein the overlay includes a flexible transparent material.

10. The input device of claim 1, wherein the touch-sensitive screen and overlay are included with a housing.

11. The input device of claim 1, further comprising a faceplate securing the overlay over a first portion of the touch-sensitive screen.

12. The input device of claim 11, wherein the faceplate comprises an aperture allowing access to the tactile features through the aperture.

13. The input device of claim 12, wherein the faceplate further includes a second aperture corresponding to a second portion of the touch-sensitive screen.

14. A computer system, comprising:

a computer; and

the input device of claim 1, wherein the input device is operable to provide input to the computer.

15. The computer system of claim 14, further comprising a display device.

16. The computer system of claim 15, wherein the computer, display device, and input device are associated with a common housing.

17. The computer system of claim 15, wherein the computer, display device, and input device are associated with a kiosk.

18. The computer system of claim 15, wherein the computer, display device, and input device are associated with a laptop computer.

19. The computer system of claim 14, wherein the computer includes a remote device.

20. A system comprising:

a touch-sensitive screen;

an overlay positioned over the touch-sensitive screen and having a plurality of tactile features;

selection logic operable to receive a request for one of a plurality of input configurations, and

display logic operable to display an input device image associated with the plurality of input configurations, wherein the input device image is based upon the positions of the tactile features of the overlay

21. The system of claim 20, wherein the selection logic includes language selection logic operable to receive a request for one of a plurality of languages.

22. The system of claim 20, wherein the selection logic includes keyboard configuration selection logic operable to receive a request for one of a plurality of keyboard configurations.

23. The system of claim 20, wherein each of the plurality of tactile features includes an extruded area.

24. A method for displaying one of a plurality of keyboard configurations on a touch-sensitive screen, the method comprising the acts of:

receiving a request for one of a plurality of keyboard configurations; and

displaying an image on a touch-sensitive screen corresponding to the keyboard configuration, wherein the touch-sensitive screen is operable to provide keyboard input to a computer based on touching of the touch-sensitive screen, and wherein the keyboard includes an overlay comprising tactile features associated therewith.

25. The method of claim 24, wherein the plurality of keyboard configurations are associated with a plurality of languages, and the request for one of a plurality of keyboard configuration comprises a request for one of the plurality of languages.

26. The method of claim 24, further including displaying a list of users on a screen, wherein each user is associated with one of the plurality of keyboard configurations and selection of a user initiates a request for the one of the plurality of keyboard configurations.
