1. An input/output (I/O) device comprising:

  • a display device that can generate a stereoscopic image in a virtual image display region;

    a depth level sensor that measures a distance to an object in a three-dimensional space detection region; and

    a control unit that comprises a memory and a processor and performs functions including;

    a depth map processing function that sets an overlapping space region of the three-dimensional space detection region, the virtual image display region and an arm movement region in which both hands can move horizontally and vertically with joints of both shoulders being a center of rotation as a manipulation region, and sets a portion other than the manipulation region in the three-dimensional space detection region as a gesture region;

    a gesture recognition function that recognizes a gesture of the hands in the gesture region; and

    a graphics processing function that manipulates the stereoscopic image based on an output of the depth level sensor in the manipulation region or based on the gesture recognized in the gesture region; and

    a calibration processing function that determines display position of the virtual image display region and adjusts automatically correlation of the three-dimensional space detection region and the virtual image display region.
