A tactile alphabet is a system for writing material that the blind can read by touch. While currently the Braille system is the most popular and some materials have been prepared in Moon type, historically, many other tactile alphabets have existed: Systems based on embossed Roman letters: Moon type; Valentin Haüy's system (in italic style)
