The authors have developed a literacy learning system that presents hiragana characters on a stereoscopic 3D display. Strokes of hiragana character were arranged in different depth direction on this learning system. The authors used a Multi-layered display (MLD) for representation depth direction. MLD is not produce asthenopia by 3D representation. It is not discrepancy between accommodation and convergence in human visual function. MLD contains two LCD that arranged front and back. MLD using hue value and chroma can create depth perception between two LCD. The authors used new method that was stereoscopic hiragana character adding different depth of strokes on MLD. The authors found that a position of depth can control and representation in each strokes. These results suggest that stereoscopic vision can help children with developmental dyslexia understand the structure of hiragana characters.
