Embodiment Construction

[0018] refer to figure 1 , shows an example of a hardware implementation of the data processing device 100 according to the present invention. The device includes a microcontroller 110 with input / output functionality 120 through which a contact sensor 150, an optional pressure sensor 160 and a display device 170 interface with the microcontroller. Touch sensor 150 and pressure sensor 160 may be used as a stack for display device 170 as is known in the art. The contact sensor, the pressure sensor and the display device may also be non-repetitive items provided by the same device. Microcontroller 110 uses an embedded RAM 130 and an embedded ROM 140 to store programs. When executing programs stored in memory 140, microcontroller 110 performs functions that will be described further below. figure 1 The picture frames in are well known in the prior art, and will not be repeated here. The device 100 may be equipped with other means known to those skilled in the art.

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.

Description

technical field [0001] The invention relates to a data processing device enabling a user to input characters, the device comprising a touch-sensitive element for realizing the function of a virtual keyboard, said element comprising at least one contact sensor for detecting a touched area on said element. [0002] The present invention also relates to a method for enabling a user to input characters, including the step of detecting a touched area on a touch-sensitive element for realizing a virtual keyboard function. Background technique [0003] Document US 6,121,960 discloses a display peripheral system comprising a touch-activated input device for generating and displaying a visual composite image to the user. The composite image also contains representations of at least one key, a standard (QWERTY) keyboard, for activating input functions, and a host image provided by the computing facility. This keyboard representation is preferably overlaid on top of the main image. T...
