Abstract

An overlay for use with a video screen having a display thereon, comprising at least one first tactilely readable area corresponding to a feature of a first graphical display on the screen.

Claims

1. An overlay for use with a screen having a display thereon, comprising at least one first tactilely readable area corresponding to a feature of a first graphical display on the screen.

2. The overlay of claim 1, wherein the tactilely readable area includes raised protrusions.

4. The overlay of claim 1, wherein the overlay is light transmissive.

5. The overlay of claim 4, wherein the overlay is substantially transparent.

6. The overlay of claim 1, wherein the overlay further comprises at least one second tactilely readable area corresponding to a feature of a second graphical display on the screen.

7. The overlay of claim 1, wherein the overlay is substantially opaque.

8. The overlay of claim 1, wherein the screen is a touch-sensitive screen and the feature selectable by touch.

9. The overlay of claim 1, further comprising means for holding the overlay in place over the screen.

3. The overlay of claim 3, wherein the protrusions are Braille characters.

10. An overlay for use with a screen, wherein the screen is a touch sensitive screen with a display containing touch selectable features thereon, comprising:

a substantially transparent substrate for placement over the screen, wherein the substrate includes a plurality of areas on the substrate that are distinguishable from each other,

wherein each area includes raised protrusions that correspond to a touch selectable feature of the display located substantially beneath the raised area on the display when the display is placed over the screen

11. A tactile method for using a device having a touch sensitive screen that has a first display thereon, comprising:

placing a first overlay on the screen, the first overlay corresponding to the first display on the screen and including a first tactilely readable area corresponding to a first selectable feature located in the first display on the screen;

determining a location of the first selectable feature on the screen by touching the first tactilely readable area on the overlay;

selecting the first selectable feature.

12. The method of claim 11, wherein the first tactilely readable area includes raised protrusions.

13. The method of claim 12, wherein the protrusions include Braille characters.

14. The method of claim 11, wherein selecting the first selectable feature includes pressing the screen at the location of the desired feature.

15. The method of claim 11, wherein selecting the second selectable feature includes entering data through a keyboard.

16. The method of claim 11 further comprising:

receiving a signal from the device;

removing the first overlay on the screen in response to the signal received;

placing a second overlay on the screen, the second overlay corresponding to a second display on the screen and including a second tactilely readable area corresponding to a second selectable feature located in the second display on the screen;

determining a location of the second selectable feature on the screen by touching the second tactilely readable area on the overlay;

selecting the second selectable feature.

17. The method of claim 16, wherein the signal is an audio signal.

18. The method of claim 17, wherein the audio signal is a voice instruction.

19. The method of claim 17, wherein the signal is a sequence of beeps, where the number of beeps correspond to the second overlay.

20. The method of claim 11, wherein the device is at least one of a scanner, a printer, and a copier.

21. A system, comprising:

a device having a touch-sensitive screen;

an overlay for placing over the touch sensitive screen having distinguishable raised portions corresponding to features located on the screen;

a sound generating mechanism for alerting a user when a particular display is on the screen.

22. The system of claim 21, wherein the sound generating mechanism is internal of the device.

23. The system of claim 21, wherein the sound generating mechanism is external to the device.

24. The system of claim 21, wherein the device is at least one of a scanner, a printer, and a copier.
