Abstract: A biometric identification device includes a biometric sensor, an encryption factor, and a microprocessor. The biometric sensor is operable to sense a biometric characteristic from a user and to generate data representing the biometric characteristic. The microprocessor is coupled to the biometric sensor and is operable to generate a user key based on the biometric characteristic and the encryption factor.

Abstract: A text entry system enables efficient entry of characters on an electronic device. The electronic device includes a display for displaying characters, an input device moveable between selectable positions and a processor operable to map a first one of the selectable positions and a second one of the selectable positions to an entered character.

Abstract: An emulated hard key that emulates a key of a user-selected keyboard is generated on a reconfigurable keyboard. In one exemplary embodiment, the reconfigurable keyboard has an array of microchambers. Each microchamber is operable to change from a first height to a second height. A keyboard emulator controller controls the array of microchambers to set a first group of microchambers to the second height. When set to the second height, the first group of microchambers collectively emulates a first key of the user-selected keyboard.
