3D INTERACTION APPARATUS, DISPLAY DEVICE INCLUDING THE SAME, AND METHOD OF DRIVING THE SAME

Provided are a three-dimensional (3D) interaction apparatus capable of recognizing a user's motions in a 3D space for performing a 3D interaction function, a display device including the 3D interaction apparatus, and a method of driving the 3D interaction apparatus. The 3D interaction apparatus includes a depth camera which obtains a depth image including depth information of a distance between an object and the depth camera; an active optical device disposed in front of the depth camera and configured to adjust a propagation path of light by refracting incident light so as to adjust a field of view of the depth camera; and a driving unit which controls operation of the active optical device.
