<p><P>PROBLEM TO BE SOLVED: To provide a VR sports system suitable for the rehabilitation by using a simpler and inexpensive input device. <P>SOLUTION: In the VR sports system 10, a turn input device 16 is used for the snow board game and a trainee 22 rides on a board 20 to turn the board 20. A USB camera 26 for taking the images containing the turn input device 16 is disposed on the front of a screen 12 and the images from the USB camera 26 undergo a processing (masking, hue conversion, binary coding, expansion and area filtering) to measure the coordinates of the center of gravity and the angle of rotation of the marker 24 is calculated from the coordinates of the center of gravity and the radius of the rotation of the board 20. The images on the screen 12 are varied according to the angle of rotation to display the images for the snow board game. This enables the detection of the angle of rotation by the processing of the images from the USB camera thereby eliminating the need for the larger turn input devices. Moreover, only by replacing the turn input device 16 with a succor input device 74 (Fig. 17, not shown), the type of the game can be changed simply thereby allowing the playing of the succor game. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
