The user interface comprises a control mode selector and a functionality limitation setting mechanism. The control mode selector is configured to display a plurality of control mode selector icons, each corresponding to one of a plurality of control modes. The plurality of control mode selector icons includes a first control mode selector icon, corresponding to the first control mode, and a second control mode selector icon, corresponding to the second control mode. The control mode selector is configured to receive a user input selection of the second control mode selector icon. The control mode selector is configured to display the second control mode by displaying a user-controllable icon corresponding to the second control mode in a main portion of the user interface. The functionality limitation setting mechanism is configured to receive a user input selection of a functionality limitation applied to the second control mode.
