ELECTRONIC DEVICE AND A METHOD IN AN ELECTRONIC DEVICE
First Claim
1. An electronic device, having a keyboard, said keyboard comprising:
- a touch sensitive element, a keyboard plate fixed over the touch sensitive element;
an array of keys integrally constructed in the keyboard plate at predetermined positions, wherein the depression of one of said keys of the keyboard plate causes said key to touch the touch sensitive element at a recognizable position on a coordinate grid of the touch sensitive element corresponding to the position of the key that is depressed; and
wherein the electronic device comprises a processor for correlating a predetermined meaning of the depressed key with the position on the grid of said touching on the touch sensitive element.

Abstract
An electronic device (1) comprises preferably at least a keyboard (4), which comprises at least one key (15a, 15b) for controlling the functions of a mobile station (1). This keyboard (4) is arranged as a keyboard plate (16). Said keyboard (4) is implemented so that it also comprises a touch sensitive element (19), over which said keyboard plate (16) is arranged so that the depression of a key is arranged to be transmitted to a touch sensitive element (19) essentially at the point of a key (15a, 15b). In addition, the electronic device (1) comprises means (21, 22b) for determining the point of depression from the touch sensitive element (19), whereby on the basis of the determined point of depression it is determined which key (15a, 15b) has been depressed.

8. A method for controlling the functions of an electronic device comprising:
-
fixing a keyboard plate over a touch sensitive element; forming an array of keys in the keyboard plate at predetermined positions, wherein depression of one of said keys of the keyboard plate causes said key to touch the touch sensitive element at a recognizable position on a coordinate grid of the touch sensitive element corresponding to the position of the key that is depressed; and causing a processor to correlate a predetermined meaning for the depressed key with the position on the grid of said touching on the touch sensitive element. - View Dependent Claims (9, 10, 11, 12, 14, 15)

13. A keyboard for an electronic device, having at least one key for controlling the functions of the electronic device, wherein said keyboard comprises:
-
a touch sensitive element; a keyboard plate fixed over the touch sensitive element so that the depression of said at least one key engages and activates the touch sensitive element at a position on the touch sensitive element corresponding to the point of the key; a position recognizing element for recognizing the touched position on the touch sensitive element; and a processor for correlating a predetermined meaning for the depressed key with the touched position recognized by the position recognizing element.

16. A computer program product including a computer readable medium said computer readable medium having processor readable program code embodied therein for operating a keyboard of an electronic device having a touch sensitive element, wherein the computer readable program code comprises:
-
computer readable program code for causing a processor of the electronic device to recognize the touch of a key of a keyboard plate mounted over the touch sensitive element and identify the position of the touch on a coordinate grid of the touch sensitive element corresponding to the position of the key; and computer readable program code for causing the processor of the electronic device to correlate a predetermined meaning for the depressed key with the position on the grid of said touching on the touch sensitive element.
