Abstract
There is disclosed a mixed reality presentation apparatus which generates and displays a three-dimensional virtual image on a see-through display device so as to allow a plurality of players to play a multi-player game in a mixed reality environment. The apparatus has a CCD camera for detecting the mallet positions of the plurality of players, and a sensor for detecting the view point position of each player in the environment of the multi-player game. The apparatus generates a three-dimensional virtual image that represents a game result of the multi-player game that has progressed in accordance with changes in mallet position detected by the CCD camera and is viewed from the view point position of each player detected by the sensor, and outputs the generated image to the corresponding see-through display device. The apparatus determines the motion of each player by detecting infrared rays output from the corresponding mallet on the basis of an image captured by the CCD camera. The view point position detected by the sensor is corrected by specifying the marker in an image obtained by a camera attached to the head of each player, and comparing the marker position in that image wit…
