Abstract (in Japanese) (See Japanese page) 
(in English) Three-dimensional electromagnetic articulography estimates the state of the receiver coil from received signal. However, when received signals at different states (position and orientation) of the receiver coil are nearly equal to each other, the state of receiver coil can not be estimated uniquely.
To resolve this problem, we optimized the alignment of transmitter coils by maximizing the difference of received signals at any two states in the measuring area. The effectiveness of our method was confirmed by both numerical and actual experiments. As a result, measurement accuracy of about 0.4 mm was obtained.
