Mobile device and method for controlling mobile device

A method for controlling a mobile device capable of communicating with a digital device, the method comprising:

• transmitting a first pointing signal to a first virtual region;
• displaying an identification (ID) identifying the digital device located in the first virtual region;
• transmitting a second pointing signal to a second virtual region;
• and
• transmitting, to the digital device, a command for execution of a specific function of the digital device, referring to a memory.

A digital device capable of communicating with a mobile device, the digital device comprising:

• a communication module configured to conduct data communication with the mobile device;
• a memory configured to store at least one data;
• and
• a controller coupled to the communication module and the memory,
• wherein the controller is configured to receive a first pointing signal from the mobile device by controlling the communication module, to access the memory, if the received first pointing signal is sensed in a first virtual region, to receive a second pointing signal from the mobile device by controlling the communication module, and to execute a specific function of the digital device, referring to the memory, if the received second pointing signal is sensed in a second virtual region.

A mobile device capable of communicating with a digital device, the mobile device comprising:

• a display module;
• a communication module configured to conduct data communication with the digital device;
• a memory configured to store at least one data;
• and
• a controller coupled to the display module, the communication module, and the memory,
• wherein the controller is configured to transmit a first pointing signal to a first virtual region by controlling the communication module, to display an identification (ID) identifying the digital device located in the first virtual region by controlling the display module, to transmit a second pointing signal to a second virtual region by controlling the communication module, and to transmit, to the digital device, a command for execution of a specific function of the digital device, referring to the memory.
