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.
