摘要

A user interface for use in an electronic device (10) comprises a display including a touch screen surface (14). The touch screen surface comprises a plurality of keys(16a-d, 17), wherein each of the plurality of keys includes a proximate sensor (20) for receiving a proximate input and a tactile sensor (22) for receiving a tactile input. The electronic device (10) comprises a controller (41, 42), wherein the controller is configured to receive a proximate input of a given one of the plurality of keys, and upon receiving the proximate input, the controller causes the display to display an enlarged indication of the function of the given one of the plurality of keys. The controller is further configured to receive a tactile input from at least one of the plurality of keys, and upon receiving the tactile input, the controller causes the electronic device to carry out the function indicated on the display regardless of the key from which the tactile input is received.
