Patent attributes
A display apparatus includes a receiving unit, a communication unit, a display unit and a control unit. The receiving unit receives from a remote control device position data corresponding to a contact position. The contact position is detected by a track pad unit and the track pad unit is included in the remote control device. The communication unit receives from an external device an operational panel used to control the external device. The display unit displays the operational panel received by the communication unit. The control unit controls the operational panel using the position data received by the receiving unit. The control unit allocates operable elements included in the operational panel to the track pad unit without changing an array of the operable elements included in the operational panel.
