Abstract: The present invention relates to an apparatus and method for designing a display for user interaction. The proposed apparatus includes an input unit for receiving physical information of a user and a condition depending on a working environment. A space selection unit selects an optimal near-body work space corresponding to the condition received by the input unit. A space search unit calculates an overlapping area between a viewing frustum space, defined by a relationship between a gaze of the user and an optical system of a display enabling a 3D image to be displayed, and the optimal near-body work space selected by the space selection unit. A location selection unit selects a location of a virtual screen based on results of calculation. An optical system production unit produces an optical system in which the virtual screen is located at the location selected by the location selection unit.

Abstract: Methods of displaying and evaluating of a motion data in a motion game apparatus are disclosed. According to the present invention, the motion of a game player following the motion of a dancer can be tracked and evaluated in real time. To induce the correct motion out of the player, in addition to simply showing the animated dancing (or any other motion) character, a display method called the “sliding ghost” metaphor is proposed. Sliding ghosts refers to consecutive freeze frames of the motion data representing key postures of the motion. Also, for enhanced viewing of the motion data, the player can set the view point and key postures may be augmented, with short texts/audio display to further inform the player of the next/current dance (motion) segment to perform. The motion of the player is captured by tracking five specific positions of the player's body.
