The main research aim of the present study focuses on issues of reading comprehension, when users with blindness receive typographic meta-data by touch through a braille display. Levels of reading comprehension are investigated by the use of 6-dot and 8-dot braille code in matched texts for the cases of bold and italic meta-data. The results indicated a slight superiority of the 8-dot braille code in reading time and scorings. The discussion considered the practical implications of the findings such as issues regarding education as well as the development of suitable design of tactile rendition of typographic signals through 6-dot or 8-dot braille code in favor of better perception and comprehension.
