Abstract
Devices and methods are described for improving the efficiency of text input by requiring more pressure to select keys on a dynamic keyboard that are improbable key presses. 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 has a lever mechanism which varies the force required to press the key. Keyboard logic on the text-entry device is programmed to change the force required to enter each key within the dynamic keyboard based on the prior entry. The keyboard logic assigns a prediction value to each key based on a statistical probability that the key will be entered next.
