    Abstract

    ![CDATA[In this study the measurement accuracy of the 3D EMA (Electromagnetic Articulograhy) system Carstens AG500 was evaluated using an optical motion capture system (Vicon). A custom-built container fixed the positions of the EMA sensors and the optical markers and a series of movements of the container within the EMA measurement field was recorded. The results show that (a) the very small error of static position measurements does not reflect the behaviour of the system in dynamic measurements and (b) that in dynamic measurements the magnitude of the error varies substantially across the three spatial dimensions.]]
