VIRTUAL OBJECT PRESENTATION SYSTEM

PROBLEM TO BE SOLVED: To provide a virtual object presentation system capable of feeding back the inner force sense of a virtual object with a high degree of freedom without restraining a body in complicated mechanical configuration. SOLUTION: A reaction force presenting member 6 can be mounted on a prescribed part of a human body and is composed of a magnetic substance. A marker tracing device 4 detects the position of the reaction force presenting member 6. A CPU 1 calculates a positional relation between the virtual object and the prescribed part of the human body in a virtual reality space from the position of the reaction force presenting member 6 detected by the marker tracing device 4 and calculates a reaction force to be applied to the reaction force presenting member 6 on the basis of that positional relation. A magnetic field generator 5 generates a magnetic field and applies the reaction force corresponding to the calculated result of the CPU 1 to the reaction force presenting member 6.
