Human tracking apparatus and method, storage medium storing program executing the method, and mobile electronic system including the apparatus

A human tracking apparatus used for a mobile electronic system, comprising:

• an upper body location detection module detecting at least one piece of upper body location for a human;
• a leg location detection module detecting at least one piece of leg location for a human;
• a tracking object selection module selecting a tracking object based on the at least one piece of upper body location and the at least one piece of leg location;
• a tracking speed and orientation calculator calculating tracking speed and orientation of the mobile electronic system for tracking the tracking object selected by the tracking object selection module;
• a motor operating the mobile electronic system;
• and
• a motor controller controlling the motor based on the tracking speed and orientation calculated by the tracking speed and orientation calculator.
