Patent ID: 7535459

Claim:
A mobile communications terminal comprising: a keypad having a plurality of touch keys and touch sensor units for sensing key inputs received from touching of the plurality of touch keys, and outputting a key input signal according to a sensed key input; and a controller detecting key input signals corresponding to two or more of the plurality of touch keys input via the keypad within a predetermined time interval, determining a priority for each of the plurality of the touch keys, and recognizing one of the two or more of the plurality of touch keys as a key input according to the determined priority, wherein the controller: determines a task which is currently being performed; identifies a first touch key among the plurality of touch keys that is not related to the task currently being performed; identifies a second touch key among the plurality of touch keys that is related to the task currently being performed; adjusts a sensitivity level of the first touch key to be lower than a sensitivity level of the second touch key; detects a key input signal corresponding to each of the plurality of touch keys; and determines a touch key having a highest sensitivity level corresponding to the detected key input signal as the key input.
