Abstract

An overlay for use with a display screen, comprising at least one first tactilely readable area, wherein the display screen includes a first feature thereon, wherein the tactilely readable area includes information in a tactilely readable format, and wherein the information identifies a first feature displayed on the screen.

Claims

1. An overlay for use with a display screen, comprising at least one first tactilely readable area, wherein the display screen includes a first feature thereon, wherein the tactilely readable area includes information in a tactilely readable format, and wherein the information identifies a first feature displayed on the screen, wherein the overlay resembles the display on the screen over which it is placed.

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

3. The overlay of claim 2, wherein the protrusions are Braille characters.

4. 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.

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

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

7. 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, the first tactilely readable area including information in a tactilely readable format, the information being specific to a first selectable feature located in the first display on the screen;

determining a location of and information about the first selectable feature on the screen by tactilely reading the first tactilely readable area on the overlay;

selecting the first selectable feature;

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, the second tactilely readable area including information in a tactilely readable format, the information being specific to a second selectable feature located in the second display on the screen;

determining a location of and information about the second selectable feature on the screen by tactilely reading the second tactilely readable area on the overlay; and

selecting the second selectable feature.

8. The method of claim 7, wherein the first tactilely readable area includes raised protrusions.

9. The method of claim 8, wherein the protrusions include Braille characters.

10. The method of claim 7, wherein selecting the first selectable feature includes pressing the screen at the location of the desired feature.

11. The method of claim 7, wherein selecting the second selectable feature includes entering data through a keyboard.

12. The method of claim 7, wherein the signal is an audio signal.

13. The method of claim 12, wherein the audio signal is a voice instruction.

14. The method of claim 12, wherein the signal is a sequence of beeps, where the number of beeps correspond to the second overlay.

15. The method of claim 7, wherein the device is at least one of a scanner, a printer, and a copier.

16. A plurality of overlays for use with a screen upon which a plurality of displays may appear, wherein each of the plurality of overlays corresponds to one of the plurality of displays and resembles that display, and wherein each overlay has at least one tactilely readable area, wherein each tactilely readable area includes information specific to a feature of the display corresponding to the overlay, the information being in a tactilely readable format.
