Outline of Final Research Achievements

The aim of this research is development of a novel mask-type wearable device named lip motion sensing mask (LIMOSK) to measure two-dimensional lip motion and its interface for silent speech interface. We modeled the magnetic sensor by mathematical expression, proposed the magnet location estimation method by using several magnetic sensors, and developed a prototype of LIMOSK which has 32 magnetic sensors. We carried out the evaluation experiments for the proposed method. As the results, the magnet location estimated errors when changing the number of magnets with 1, 2 and 3, were 0.47mm, 0.64mm and 2.71mm, respectively. It was confirmed that the proposed system is able to estimate the magnet location by the high precision.
