The LAMBDA system aims at facilitating blind students to write, read and process text and mathematical expressions in an educational context. Mathematical expressions and text are presented to the user in a linear form on the braille display and through speech output. Visual rendering in a linear form enables the sighted reader to understand what the blind user is writing. Asynchronous two-dimensional visual rendering of mathematical notation is available. Many editing and exploration operations are available. The LAMBDA system imports and exports MathML files. That makes possible transnational exchange of scientific digital resources. In the workshop are presented the main features of the LAMBDA system, state-of-the-art and future development and in which educational contexts the LAMBDA system is used.
