Mobile device providing 3d interface and gesture controlling method thereof

A mobile device that provides a three-dimensional interface, comprising:

• a communication unit configured to perform wireless communication;
• a memory unit configured to store user data and data;
• a display unit configured to display a virtual three-dimensional space using the three-dimensional interface;
• a sensing unit configured to sense a still picture and a moving picture of a physical space and including at least one front-facing sensor configured to sense at least one gesture of a user;
• and
• at least one processor configured to control the communication unit, the memory unit, the display unit, and the sensing unit,
• wherein the at least one processor moves an object existing in the virtual three-dimensional space according to the detected gesture, and
• when the mobile device or the user moves, the at least one processor controls the three-dimensional interface such that a sight of the user toward the object is varied.

A gesture control method of a mobile device configured to provide a three-dimensional interface, the method comprising:

• displaying a first portion of a virtual three-dimensional space so that the first portion is superimposed on a physical space, using the three dimensional interface;
• displaying a second portion of the virtual three-dimensional space using the three-dimensional interface;
• detecting at least one gesture of at least one user using at least one of one or more front-facing sensors and one or more back-facing sensors;
• and
• moving an object existing in the virtual three-dimensional space according to the detected gesture such that the at least one user interacts with the virtual three-dimensional space.
