Transparent-Resinous-Ultraviolet-Curing-Type Braille (TRUCT Braille) signs printed over printed characters do not disturb sighted readers, thus these signs have spread rapidly. However, it is pointed out that sight disabled readers are hard to read TRUCT Braille because patterns of dots that consist of Braille (such as dot-height and distance-between〜dots) are different from each printing marker. In this study, for the purpose of defining the readability of TRUCT Braille, we product the various patterns of TRUCT Braille and examine the influence of the dot-height and the distance-between-dots. The participants are beginners of Braille reading with normal vision to exclude the experience of reading Braille. They are given subjects to discriminate 6 letters (one of six dots is freely missing) consisted of various patterns of TRUCT Braille. From this study, we suggest the basical patterns of TRUCT Braille that are easy to discriminate.
