Abstract

A device with a user interface includes a display screen, input keys, and a controller that is configured to control the display screen to display a three by three matrix of fields wherein each of the fields may contain a symbol, and wherein the controller is further interfaced with a number of the input keys, for example four selection keys or eight selection keys, in such a way that one of the symbols is selected by operation of at least one of these selection keys and some of the symbols are selected by simultaneous operation of two or more of the selection keys.

Claims

1. A device with a human interface comprising a display, input keys, and a controller that is configured to control

the display to display a three by three matrix of fields wherein each of the fields contains a symbol, and wherein the controller is further interfaced with

four selection keys of the input keys in such a way that one of the symbols is selected by operation of at least one of the four selection keys and some of the symbols are selected by simultaneous operation of two of the selection keys.

2. A device according to claim 1, wherein the four selection keys are arranged in a two by two matrix.

3. A device according to claim 1, wherein the display and the four selection keys are positioned on the same side of the device.

4. A device according to claim 1, wherein the display and the four selection keys are positioned on opposite sides of the device.

5. A device according to claim 2, wherein the controller is configured so that operation of a single selection key selects a corresponding corner field of the three by three matrix.

6. A device according to claim 2, wherein the controller is configured so that simultaneous operation of two selection keys selects a corresponding middle field of the three by three matrix.

7. A device according to claim 1, wherein the controller is configured for hierarchical selection of a symbol to the device.

8. A device according to claim 1, wherein the controller is further configured to control a second set of four selection keys of the input keys, and wherein the first set of four selection keys and the second set of four selection keys are mounted on opposite sides of the device.

9. A device according to claim 8, wherein the first set of four selection keys is allocated for selection at one level of a hierarchical selection scheme and the second set of four selection keys is allocated for selection at another level of the hierarchical selection scheme.

10. A device according to claim 8, wherein selection of a symbol is performed by simultaneous release of all keys of the set of selection keys associated with the first hierarchical level disregarding the state of the selection keys of the other set.

11. A device according to claim 10, wherein selection of a symbol is performed by pressing at least one of the second set of four selection keys without pressing any keys of the first set of four selection keys.

12. A device according to claim 1, wherein the four selection keys are constituted by specific keys in the keyboard of a hand held device.

13. A device according to claim 1, wherein the four selection keys are constituted by specific keys in the keyboard of a computer.

14. A device according to claim 1, wherein the function of the four selection keys are performed by specific keys in the keyboard of a hand held device.

15. A device according to claim 1, wherein the function of the four selection keys are performed by specific keys in the keyboard of a computer.
