Outline of Final Research Achievements

Braille learners require a lot of time to acquire Braille character patterns. Therefore, there has been a call from educators to enhance Braille learning environments. Recently, transparent resinous ultraviolet-curing type (TRUCT) Braille signs are becoming more and more popular in Japan. These signs have begun to be used in public facilities. Naturally, it is expected that beginner Braille readers will utilize these signs. However, its printing quality is not so good and there is hardly any research on the easiest Braille patterns for beginners who are trying to learn Braille. In this study, we developed new TRUCT Braille printing method instead of silk screen printing method, and also examined the relationship between readability of TRUCT Braille and character　sizes as an experimental factor for beginner Braille readers.
