Abstract

A method of controlling the operation of a mobile terminal is provided. By dynamically selecting or setting a specific function of a mobile terminal according to a change in pressure or contact areas sensed by a plurality of touch sensors which cover the mobile terminal, a user can easily select or set a specific function of the mobile terminal according to his or her intention, and easily recognize information displayed on a screen of the mobile terminal.
