Apparatus and method for providing additional caller ID information

A portable device comprising:

• a communication unit configured to transmit and receive digital data over a network;
• a storage unit configured to store the digital data;
• a sensor unit configured to detect a user's face on the portable device;
• a display unit configured to display the digital data;
• and
• a controller configured to control the units,
• wherein the portable device is configured to:
• receive an incoming call,
• detect the user's face on the portable device,
• display additional data on the incoming call when the user's face is detected, the additional data being some of a plurality of data collected from a plurality of data sources corresponding to caller ID of the incoming call,
• display other additional data included in the collected data per predetermined time interval when the user's face is continuously detected, and
• detect a user input for answering or rejecting the incoming call.

• a sensor unit configured to detect a user's face on the portable device;
• a display unit configured to display the digital data;
• and
• a controller configured to control the above units,
• wherein the portable device is configured to:
• receive a first incoming call,
• detect the user's face on the portable device,
• display additional data on the first incoming call when the user's face is detected, the additional data being some of a plurality of data collected corresponding to caller ID of the incoming call,
• display other additional data included in the collected data per predetermined time interval when the user's face is continuously detected,
• detect a user input for answering to or rejecting the incoming call,
• store the data displayed at the time when the user input is detected as primary data, and
• display the primary data when a second incoming call is received from the caller ID after the first incoming call ends.
