Patent ID: 7489302

Claim:
A wireless handheld mobile communication device having a keypad arrangement configured for minimizing typing errors when an intended key and an adjacent key are engaged at substantially the same time by a typist because of finger overlap, the device comprising: a housing configured to be cradled in a palm of a user's hand and having a display located in a top portion thereof for displaying information to the user and a keypad arrangement exposed for user actuation below the display, the keypad arrangement comprising: a support frame face upon which a plurality of depressible typing keys are mounted and each of the keys is moveable between actuated and unactuated positions wherein the actuated position is closer to the support frame face than the unactuated position; each of the keys having a plurality of actuators interconnected to a body of the key at a position toward the support frame face from the key body and each of the plurality of actuators being moveable with the key body between actuated and unactuated positions wherein the actuated position is closer to the support frame face than the unactuated position and each of the actuators is biased toward the unactuated position; and each of the plurality of actuators interconnected to a particular key body being spaced apart, one from the others, and the key body comprising a flexible portion between the plurality of actuators, the flexible portion being sufficiently flexible to allow one actuator to be in the actuated position while at least one of the other of the plurality of actuators on that key body is in the unactuated position.
