Abstract

There are several types of motion capture system for virtual reality. The authors propose a new type of motion capture system that uses rotating magnetic field for angular position detection and differential magnetic field for linear position detection. The detection is based on calculation of correlation that makes accuracy of measurement and tolerance to noise high enough, and it is also based on frequency multiplex method that enables 6-axis measurement simultaneously. The experiments were carried out and results showed efficiently good performance for virtual reality
