The authors have developed a literacy learning system for children with developmental dyslexia. The system presents alphabetic characters on a stereoscopic 3D display. In order to make the character structure more understandable, the character was expressed in three dimensions by continuously changing the stereoscopic depth from the starting point to the terminal point of the character stroke. However, stereoscopic displays are not widely used in schools and can be difficult to put to practical use. The purpose of this study was to develop a fractional view display that does not employ special equipment. We compared the comprehensibility of 3D characters presented on a depth fused 3D display and on a fractional view display. These results indicate that a fractional view display can make the structure of large characters understandable.
