Maria Theresia is a tactile typeface system for education, designed for readers with visual imparement. The starting point for the system and accompanying research was Klein's type from 1810. This tactile typeface designed for the blind was based on Latin letterforms and was widely used. It was later replaced by Braille alphabet, which is more efficient in the reading process and easier to reproduce. Maria Theresia system is designed to support the process of learning letterforms of Latin alphabet by people with visual imparement. It is not aiming to be braille substitute or competition but is intended to be used in educational materials. Maria Theresia system includes tactile sizes: smaller — for reading and larger, allowing to observe the construction of the letterforms in detail — for learning, as well as variants with different line density. The goal of the accompanying tests is to suit the system to the needs and preferences of readers and to the possibilities of reproducing techniques.
