Abstract

An indication of interaction with a touch-sensitive display is provided. A soft key is displayed on the touch-sensitive display. Contact with the touch-sensitive display corresponding to interaction with the soft key is detected. The periphery of the soft key smoothly changes in optical intensity in response to detecting the contact.
