Abstract
Devices and methods are disclosed which relate to improving the efficiency of text input by measuring the angle of each key press and rejecting improbable keys pressed at an off-center angle. Examples include a text-entry device which has logic for resisting error while the user enters text on a keyboard of the text-entry device. Each key determines the angle at which the key is pressed. Keyboard logic on the text-entry device assigns a range of acceptable angles to each key. If a key is pressed within the range of acceptable angles, which is typically around the center, then the entry is permitted. If a key is pressed outside the range of acceptable angles, which is typically on the edges, then the entry is denied. Once text is entered, the keyboard logic assigns a prediction value to each key based on a statistical probability that the key will be entered next. The keyboard logic then adjusts the range of acceptable angles based on that statistical probability.
