Research content

Sign Language is a visual language that uses a system of Manual Signals and Non-Manual Markers as the means of communication. Different from spoken language, sign language has no widely used notation system. Our goal is to construct a system that can automatically generate animation of translated sign language from spoken Japanese. We propose an NVSG element model, a hierarchical morphological description method that can describe the sign language structure. As a result of descriptions using this method, it is to visually grasp the hierarchical structure of morphemes on a linguistic level. We are proceeding with a further study on how to synthesize new words that are not found in the current dictionary by taking advantage of this morpheme dictionary described using NVSG elements. In addition, we Construct of screening Test for Visual Perception skills(STVP) on children with developmental Disorders. This system is setting for detecting the child's weakness of visual perception.
