Abstract: An input signal corresponding to an action other than a drag on any virtual keyboard causes an erroneous string having at least two characters with an incorrect character other than the last character to be displayed. A second input signal corresponding to a drag on a virtual keyboard triggers entry into an error correction mode. A first incorrect character is located, a corrected input is determined according to an angle and a slide direction of the first drag, and the layout and geometry of the virtual keyboard; the first incorrect character is replaced with the corrected input to provide and display a first corrected string. The replacement of the first incorrect character and the display of the first corrected string occur without input from any source external to the device other than the first and the second input signals.

Abstract: A system for inputting data in an electronic device comprising: a segmented pattern on a touch sensitive graphical user interface; a numeric value associated to each of the segments; a character table stored in the electronic device, the said character table having at least one set of numeric values associated to at least one character; a set of characters displayed on the segmented pattern, each said character associated to at least one segment of the segmented pattern and the numeric value of that said segment in at least one set of the numeric values stored in the character table and the said set associated to the said character; an input signal received on at least one segment to provide an input having numeric values; a matched character determined according to input having numeric values and the character table; wherein the matched character is displayed on the touch sensitive graphical user interface of an electronic device, stored and the segmented pattern on the touch sensitive graphical user interfa
