Abstract
A mobile device and a method for improving the reliability of user's touches on a touchscreen are based on the virtual subdivision of a keyboard zone in an easy zone, where the user can easily play the keys, and a difficult zone, where the user has some difficulty to correctly touch the keys. The touches in the easy zone are not corrected, while the touches in the difficult zone may be corrected according to a number of criteria. In any case the layout of the virtual keyboard does not change.
Claims16
A mobile device for improving the reliability of a user's touch on a touchscreen, comprising said touchscreen adapted to display a keyboard zone comprising a plurality of keys, and processing means configured for:
- receiving an input signal from said touchscreen carrying data on a user's touch event;
- computing, on the basis of said input signal, a selected position of said user's touch, said selected position of said user's touch belonging to a first zone of said keyboard zone or a second zone of said keyboard zone, the first zone being separate from the second zone, wherein a plurality of first keys selected from the plurality of keys are disposed within the first zone and a plurality of second keys selected from the plurality of keys are disposed within the second zone;
- discerning whether said selected position of said user's touch belongs to said first zone of said keyboard zone or said second zone of said keyboard zone;
- computing a corrected position for said selected position of said user's touch when said selected position of said user's touch belongs to said first zone, by executing correction instructions defining a correction to apply to said selected position of said user's touch;
- and
- associating said selected position of said user's touch with at least one of said plurality of keys displayed on said keyboard zone, wherein when said selected position of said user's touch belongs to said second zone, said selected position is associated with a key of said plurality of keys that is nearest to said computed selected position, while when said selected position of said user's touch belongs to said first zone, said selected position is associated with a key of the plurality of keys, which among those located adjacent to said selected position, is farthest from a designated point that is located in said second zone, the designated point having been determined as part of the step of computing the corrected position;
- and
- generating a signal corresponding to a touch on said at least one of said plurality of keys associated with said selected position of said user's touch.

A method for improving the reliability of a user's touch on a touchscreen that comprises a keyboard zone displaying a plurality of keys, comprising:
- a touching phase, wherein a user generates an input signal by touching a point on the keyboard zone of said touchscreen;
- a detection phase, wherein a selected position by said touch is computed on the basis of said input signal by a processor, said selected position belonging to a first zone of said keyboard zone or a second zone of said keyboard zone, the first zone being separate from the second zone, wherein a plurality of first keys selected from the plurality of keys are disposed within the first zone and a plurality of second keys selected from the plurality of keys are disposed within the second zone;
- a discerning phase, wherein it is evaluated, by means of the processor, whether said selected position belongs to said first zone of said keyboard zone or said second zone of said keyboard zone;
- a correction phase, wherein, when said selected position of said detected touch belongs to said first zone, a corrected position of said selected position is computed, through said processing means, by executing correction instructions defining a correction to apply to said selected position;
- an association phase, wherein said selected position is associated, by said processor, with at least one of said plurality of keys displayed on said keyboard zone, wherein when said selected position belongs to said second zone, said selected position is associated with a key of said plurality of keys that is nearest to said selected position, while when said selected position belongs to said first zone, said selected position is associated with a key of said plurality of keys, which among those located adjacent to said selected position, is farthest from a designated point that is located in said second zone, the designated point having been determined by said processor as part of the correction phase;
- and
- an output phase, wherein a signal corresponding to a touch on said at least one of the plurality of keys associated with the selected position is generated by said processor.
