Abstract

The invention relates to a data processing device ( 100 ) enabling a user to input characters, the device comprising a touch-sensitive member ( 200 ) arranged to function as a virtual keyboard, said member including at least one touch sensor ( 160 ) for detecting touched zones on said member. The device further comprises key allocation means ( 110 ) for allocating at least two reference keys ( 220 ) of the virtual keyboard in response to said detection of the touched zones. The device comprises at least one pressure sensor ( 170 ) for sensing a finger ( 250 ) causing a force on the touch-sensitive member higher than other fingers when more than one finger touches said member. A recognition of a key stroke may be realized. The reference keys may be reallocated upon a user's request or detection of a predetermined condition. The invention also relates to a method of enabling a user to input characters.
