Predictive force sensitive keypad

摘要

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.

1. A device comprising:
a processor; and a memory in communication with the processor, the memory storing computer-readable instructions that, when executed by the processor, cause the processor to perform operations comprising
detecting selection of a key on a keyboard, the key being associated with a character;determining, based upon the character, prediction values for keys on the keyboard, each of the prediction values comprising a statistical probability that a corresponding key on the keyboard is to be selected;assigning the prediction values to the keys; andvarying a force to press one of the keys by varying a viscosity of a damping fluid at the one of the keys, wherein varying the force comprises adjusting a current to the damping fluid based upon a corresponding prediction value associated with the one of the keys.
