Writing and reading formulas or perceiving the graph of a function stand in the way of a blind student for an efficient and complete study of Math. L-MATH provides the following modules to blind students.

- BlindMath: a very efficient editor that allows blind users to insert a formula and obtain, as output, a Latex file.
- TalkingMath: an application that is able to read a formula in a very efficient way by means of an original adaptative algorithm.
- BlindGraph: an application that allows graph exploration.

A new cheap device, AudioTact, is able to generate, at the same time, sonorous and tactile stimulus, for images that have been opportunely enriched.

Looking at the graph of a function, a student can easily perceive elements of primary importance as: where the function grows or decreases; where the maximums, the minimums and the flexes are; where the points of discontinuity are. If the user knows them, she/he can find them, and understand how the graph proceeds. L-MATH permits the contemporary use of aural and haptic feedbacks to detect meaningful aspects.
