Abstract

A portable electronic device comprising a display arranged on a first side, the display having a first touch sensitive surface. The device also comprises a second touch sensitive surface separate from the display and a processor responsive to a plurality of user control commands. The device further comprises a touch detector, responsive to a user touching at least one of the first and second touch sensitive surfaces, for detecting touch input regions each corresponding to a respective one of the user control commands and for initiating a response, by the processor, to a user control command corresponding to a detected touch input region. The touch input regions are assigned to corresponding user control commands so that at least one subset of the commands corresponds to touch input regions on the first surface and at least another subset of the commands corresponds to touch input regions on the second surface.

Claims

1. A portable electronic device comprising:

a display arranged on a first side of the device, the display having a first touch sensitive surface;

a second touch sensitive surface separate from said display;

a processor responsive to a plurality of user control commands; and

a touch detector, responsive to a user touching at least one of said first touch sensitive surface and said second touch sensitive surface, for detecting touch input regions each corresponding to a respective one of said user control commands and for initiating a response, by the processor, to a user control command corresponding to a detected touch input region;

in which said touch input regions are assigned to corresponding user control commands so that at least a first subset of said user control commands correspond to touch input regions on said first touch sensitive surface and at least a second subset of said user control commands correspond to touch input regions on said second touch sensitive surface.

2. A device according to claim 1, in which said second touch sensitive surface is arranged on a second side of said device substantially opposite the first side.

3. A device according to claim 2, in which said second touch sensitive surface is positioned on the second side so as to be substantially aligned with said display so that in a direction normal to the plane of said display, said second touch sensitive surface substantially overlies the display.

4. A device according to claim 1, in which said user control commands comprise text input commands to said device.

5. A device according to claim 4, in which said first subset of user control commands comprises alphanumeric character input commands and said second subset of user control commands comprises non-alphanumeric character input commands.

6. A device according to claim 1, comprising a feedback indicator generator operable to generate feedback to a user when the user is in physical contact with one of the touch input regions.

7. A device according to claim 6, in which the feedback to the user is haptic feedback.

8. A device according to claim 1, in which:

said user control commands comprise;

a user motion control command associated with a control motion of said device which corresponds to a predetermined movement of said device performed by the user; and

a confirmation user control command associated with said user motion control command, said confirmation user control command corresponding to a respective one of the touch input regions;

said device comprises a motion detector operable to detect said control motion of the device; and

said processor is operable to initiate said user motion control command in response to detection of said control motion by said motion detector if detection of the touch input region corresponding to said confirmation user control command occurs substantially simultaneously with the detection of said control motion.

9. A device according to claim 8, in which said second subset of user control commands comprises said confirmation user control command.

10. A method of controlling a portable electronic device comprising a display arranged on a first side of the device, said display having a first touch sensitive surface, a second touch sensitive surface separate from said display, and a processor responsive to a plurality of user control commands, the method comprising:

detecting, in response to a user touching at least one of said first touch sensitive surface and said second touch sensitive surface, touch input regions each corresponding to a respective one of the user control commands; and

initiating a response, by the processor, to a user control command corresponding to a detected touch input region;

in which said touch input regions are assigned to corresponding user control commands so that at least a first subset of said user control commands corresponds to touch input regions on said first touch sensitive surface and at least a second subset of said user control commands corresponds to touch input regions on said second touch sensitive surface.

11. A tangible computer-readable storage medium on which computer readable instructions of a computer program are stored, the instructions, when executed by a computer, cause the computer to perform a method of controlling a portable electronic device comprising a display arranged on a first side of the device, said display having a first touch sensitive surface, a second touch sensitive surface separate from said display, and a processor responsive to a plurality of user control commands, the method comprising:

detecting, in response to a user touching at least one of said first touch sensitive surface and said second touch sensitive surface, touch input regions each corresponding to a respective one of the user control commands; and

initiating a response, by the processor, to a user control command corresponding to a detected touch input region;

in which said touch input regions are assigned to corresponding user control commands so that at least a first subset of said user control commands corresponds to touch input regions on said first touch sensitive surface and at least a second subset of said user control commands corresponds to touch input regions on said second touch sensitive surface.
