Braille reading is a complex task involving many factors; these include sentence-level factors (e.g., semantic structure and braille character structure) and individual-level factors (e.g., reading style, perceptual and cognitive factors, and the onset of blindness). These factors may cause significant individual differences in reading speed. The purpose of this study is to examine what factors influence braille reading speed and individual differences in reading speed. Thirty-eight braille readers participated in the experiment, which included the measurement of braille reading speed, working memory, and tactile sensitivity. Using hierarchic linear model (HLM), the influence of individual-level factors and sentence-level factors on braille reading speed was examined. The results of the analysis showed that both sentence-level factors (the number of vocabulary, word familiarity, and the number of dots per braille character) and individual-level factors (residual vision and the onset of blindness) significantly influence braille reading speed.
