Patent ID: 7610558

Claim:
An information processing apparatus for generating and displaying a mixed reality image of a mixed reality space in which a plurality of players have virtual objects by their hands respectively, by combining a real space image and a virtual space image representing a virtual object, comprising: a first measuring unit adapted to measure a position of the hand of the player; a second measuring unit adapted to measure a view position and a view direction of a head mount display of the player, said second measuring unit being disposed on the head mount display; a management unit adapted to manage a stage of a virtual space based on the measured position of the hand of the player; a generation unit adapted to generate the virtual space image based on the state of the virtual space, the measured view position and the view direction of the player; a combining unit adapted to combine the virtual space image and the real space image, with the head mount display adapted to display the combined image; an upcast action detecting unit adapted to detect an upcast action based on a shifting speed of the hand in an upward direction; a first judging unit adapted to judge that the hand is stopped if the shifting speed of the hand in the upward direction becomes smaller than a predetermined value after the upcast action was detected by said upcast action detecting unit; a determining unit adapted to determine from other players a partner player to whom the virtual object is upcast, on the basis of the view position and the view direction of the player and view positions of other players when it is judged that the hand is stopped; and a control unit adapted to control the state of the virtual space so that in the virtual space a position of the virtual object corresponding to the hand of which the upcast action was detected is changed toward the partner player, according to the detected result of the upcast action.
