Abstract

A portable device is provided, which includes a touch screen and at least one area bearing reference information, referred to as a reference area, which can be identified by detecting a variation in the surface state on the device.

Claims

1. A portable device comprising:

a touch screen; and

at least one area carrying a piece of position-marking information, called a position-marking area, identifiable by detection of a variation of a surface state on said device, wherein at least one position-marking area is situated on at least one side of said device or on a surface not parallel to the surface of said touch screen.

2. The device according to claim 1, wherein said position-marking information appears in relief relatively to at least one surface of said device.

3. The device according to claim 1, wherein the device comprises means for deactivating the display of said touch screen.

4. The device according to claim 1, wherein the device comprises at least one key outside said touch screen.

5. The device according to claim 1, wherein said piece of position-marking information corresponds to a marking demarcating a boundary between two distinct virtual regions of the touch screen.

6. The device according to claim 5, wherein said marking demarcates the middle of one side of said touch screen.

7. The device according to claim 1, wherein said piece of position-marking information corresponds to a marking that demarcates the width of a virtual key of the touch screen.

8. The device according to claim 1, wherein position-marking area is situated outside the touch screen and the variation of the surface state is selected from a group comprising:

a variation of the surface state embossed on a surface of the device;

a variation of the surface state etched on the surface of the device;

a combination of a variation of the surface state embossed on the surface of the device and a variation of the surface state etched on the surface of the device.

9. The device according to claim 1, wherein said position-marking area is defined by a coating on the surface of the touch screen of said device comprising an optical varnish.

10. The device according to claim 9, wherein said position-marking information corresponds to a marking that demarcates a predetermined key of said touch screen.

11. The device according to claim 1, wherein position-marking information corresponds to a representation in Braille of at least one key of said touch screen.

12. The device according to claim 1, wherein the device comprises audio means for guiding a user in browsing through an application rendered on the touch screen.

13. The device according to claim 1 wherein the device comprises disabling means for making activation of a virtual key of said touch screen by pressure applied by a user subject to the execution of an additional action by said user.

14. The device according to claim 1, wherein the device comprises means for signaling activation of a virtual key on said touch screen.
