Patent ID: 7382357

Claim:
A reconfigurable interface, comprising: a reconfigurable keyboard configurable to emulate a first user-selected keyboard, the reconfigurable keyboard comprising an array of microchambers, each microchamber coupled to a port though which a fluid is injected into the microchamber for changing the microchamber from a first height to a second height, each port including a bi-stable valve operable for regulating the injection of the fluid into the microchamber; and a keyboard emulator controller operable to emulate a first user-selected keyboard upon the reconfigurable keyboard, the emulation comprising setting a first group of microchambers in the array to the second height by operating a respective set of bi-stable valves for injecting the fluid into each of the first group of microchambers, whereupon the first group of microchambers collectively constitute a first emulated hard key that emulates a first key of the first user-selected keyboard.
