<p>A handheld information processing device such as a mobile telephone or portable computer has a normal operating mode in which it executes information processing operations in response to user activation of user controls from the user control interface. Furthermore, the device has a remote control signal transmitter coupled to its processing circuit. The processing circuit is configured to switch automatically to a remote control mode when no user activation of the user controls has been detected for a predetermined time duration. In an embodiment handheld information processing device switches to the remote control mode only if it is within a predetermined range of spatial locations after the time duration. In the remote control mode the processing circuit responds user activation of the user controls substantially only by causing the remote control signal transmitter to transmit conventional remote control command signals to equipment like TVs, recorders etc.</p> |
