Analysis of Phonemes of Linear Hand Movements in Japanese Sign Language Using 3D Motion Capture

Abstract

We analyze the phonemes of linear hand movements in Japanese Sign Language by using data measured by high-precision optical motion capture. The results of the analysis show that for words with phonemes of movements in six directions (Up, Down, Outward, Toward, Right, and left), the trajectories of the movements fall within a certain range, suggesting that the linguistically defined movement phonemes can be distinguished as movements in three-dimensional space.
