Abstract

An enhanced display device may include a touch screen having a display surface configured to display images, the touch screen being configured to output a signal indicative of where on the display surface the touch screen is touched. The display device may also include a controller configured to generate a virtual keyboard image including a number of virtual keys for display on the display surface, and at least one arrangement configured to receive a variable, wherein the controller is configured to generate the virtual keyboard image with at least one varying touch area based on the received variable.

Claims

1. A display device comprising:

a touch screen having a display surface configured to display images, the touch screen being configured to output a signal indicative of where on the display surface the touch screen is touched;

a controller configured to generate a virtual keyboard image including a plurality of virtual keys for display on the display surface; and

at least one arrangement configured to receive a variable;

wherein

the controller is configured to generate the virtual keyboard image with at least one varying touch area based on the received variable.

2. A display device according to claim 1, wherein said variable is at least one of an input frequency of virtual key strokes of a user, motion or ambient light strength.

3. A display device according to claim 1, wherein said controller is configured to choose, as the display portion, increased sensitivity for remaining areas.

4. A display device according to claim 1, wherein the virtual keyboard is an image including a standard alphabet key array.

5. A display device according to claim 1, further comprising a predictive text engine, configured to, based on a touch on the display surface corresponding to a virtual key, generate a signal to said controller to generate said virtual keyboard image with varying touch area.

6. A display device according to claim 1, wherein said controller is configured to be in a first or a second mode, wherein in said first mode the touch area is not varied and in said second mode, said touch area is varied with respect to said received variable.

7. A display device according to claim 1, further comprising a predictive text engine and a key input frequency counter, configured to, based on input frequency and a predicted text by said predictive text engine, generate a signal to said controller to generate said virtual keyboard image with varying touch area.

8. A portable telephone device comprising a display device comprising:

a touch screen having a display surface configured to display images, the touch screen being configured to output a signal indicative of where on the display surface the touch screen is touched;

a controller configured to generate a virtual keyboard image including a plurality of virtual keys for display on the display surface; and

at least one arrangement for configured to receive a variable;

wherein

the controller is configured to generate the virtual keyboard image with at least one varying touch area based on the received variable.

9. A device according to claim 8, further comprising at least one of an input frequency counter of virtual key strokes, motion sensor or ambient light strength sensor.

10. A device according to claim 8 wherein the virtual keyboard is an image including a standard alphabet key array.

11. A device according to claim 8, further comprising a predictive text engine, configured to, based on a touch on the display surface corresponding to a virtual key, generate a signal to said controller to generate said virtual keyboard image with varying touch area.

12. A device according to claim 8, wherein said controller is configured to be in a first or a second mode, wherein in said first mode the touch area is not varied and in said second mode, said touch area is varied with respect to said received variable.

13. A portable electric device including a display device comprising:

a touch screen having a display surface configured to display images, the touch screen being configured to output a signal indicative of where on the display surface the touch screen is touched;

a controller configured to generate a virtual keyboard image including a plurality of virtual keys for display on the display surface; and

at least one arrangement for configured to receive a variable;

wherein

the controller is configured to generate the virtual keyboard image with at least one varying touch area based on the received variable.

14. A method of displaying a virtual keyboard image on the display surface of a touch screen configured to output a signal indicative of where on the display surface the touch screen is touched, the method comprising:

sensing one variable effecting user character input, and

responsive to the sensed variable, increasing predetermined screen areas relevant to a specific information displayed.

15. A computer program code comprising program code means for performing displaying a virtual keyboard image on the display surface of a touch screen configured to output a signal indicative of where on the display surface the touch screen is touched, the computer code comprising:

a code set for sensing one variable effecting user character input, and

a code set responsive to the sensed variable for increasing predetermined screen areas relevant to a specific information displayed.

16. A computer product comprising program code means stored on a computer readable medium for performing displaying a virtual keyboard image on the display surface of a touch screen configured to output a signal indicative of where on the display surface the touch screen is touched, the computer code comprising:

a code set for sensing one variable effecting user character input, and

a code set responsive to the sensed variable for increasing predetermined screen areas relevant to a specific information displayed.
