METHOD FOR GENERATING VIRTUAL SPACE MOVEMENT INFORMATION AND DEVICE FOR INTERFACING VIRTUAL SPACE MOVEMENT

摘要

PROBLEM TO BE SOLVED: To convert the movement of a user's foot into movement information in a virtual space by using a non-contact type position measurement system for measuring the position of a mobile object by utilizing ID tags. SOLUTION: This virtual space movement interface device for inputting movement information necessary to the movement processing of a virtual space display image comprises the ID tags, an ID reader and a processor. The ID tags are arranged on a floor or a platform at prescribed intervals, receive power supply by an electromagnetic induction method and respectively transmit their inherent ID data. The ID reader is attached to the foot of the user standing on the floor or the platform, feeds power to an ID tag and receives ID data transmitted from the ID tag. The processor inputs the ID data received by the ID reader, converts the ID data into position information on the basis of a mapping table for making the ID data correspond to the spatial position of the floor or the platform, and also converts the change of the position information due to the movement of the user's foot into the movement information in the virtual space display image.
