Keyboard error reduction method and apparatus
First Claim
1. A method for use in deciding a selectable portion that is selected during a selection operation from amongst a first plurality of selectable portions of an image displayed on a screen, where the selection operation indicates a selected position in the image and each of said first plurality of selectable portions has a representative position within the image, the method comprising:
- receiving input data identifying the selected position, indicated during the selection operation; and
deciding on at least one candidate for the selected selectable portion, using the position of the selected position relative to the representative positions of a second plurality of the selectable portions.

Abstract
In a mobile telephone (10) with a virtual keyboard and a touch screen (12), with individual virtual keys (22) having their own representative positions. During a selection operation to select a key (22), where the touch screen is touched becomes the selected position. The distance between the selected position and adjacent representative positions is used to decide a first set of candidate keys. These candidate keys are then used to provide a set of potential words that would result from the input of any one of those keys. A list of candidate words is then produced and displayed on a display area (26) based on the frequency of use of the words in the set of potential words and the distances between the selected position and the representative position of the keys (22). Once a key (22) is confirmed as having been selected, the offset between the selected position and the representative position of that key is used to re-calibrate that representative position.

13. A method for use in displaying a plurality of selectable portions in an image displayed on a screen, individual selectable portions being selected during selection operations where a selection operation indicates a selected position on the image, and each of said plurality of selectable portions having a representative position on the image, the method comprising:
-
determining a selectable portion selected through a selection operation;
determining an offset distance between the selected position and the representative position of the selected selectable portion; and
repositioning the representative position of the selected selectable portion using at least the determined offset distance.

14. A driver circuit for use in deciding a selectable portion that is selected during a selection operation from amongst a first plurality of selectable portions of an image displayed on a screen, where the selection operation indicates a selected position in the image and each of said first plurality of selectable portions has a representative position in the image, the circuit comprising:
-
a memory for storing the representative positions of the selectable portions an input for receiving a selected position from a selection operation; and
a microprocessor for deciding on one or more candidates for the selectable portion being selected through the selection operation, using the position of the received selected position relative to the representative positions of a second plurality of the selectable portions, stored in the memory. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
