A new magnetic method of motion capture is proposed. To produce reference magnetic fields, this method uses a simple coil system which consists of two pairs of square coils, which are placed along the sides of two sets of opposite surfaces of a cubic frame where one pair of the coils is rotated through 90 degrees from the other. Two quasi-uniform magnetic fields and one gradient magnetic field are successively generated by these coils and are measured by a triaxial magnetic sensor attached to the moving object. The coordinates of the object are calculated by the Gauss-Newton method from several scalar functions defined by scalar products of the measured magnetic field vectors. The effective area where motion capture can be stably performed was numerically estimated to be a little larger than a cubic area with an edge length of 60 percent of that of the cubic frame.
