Math and Lambda: The Experience of Blind Students and their Teachers
Cristian Bernareggi
The LAMBDA system is a software application designed to facilitate blind students in making mathematics at school. The main features of the system include:
-
a 8-dot Braille code that blind that extends the national 6-dot Braille codes. This code was designed to be easy to learn and read;
-
an interaction paradigm, based on the linearization of the mathematical notation, designed to navigate and process mathematical expressions through speech synthesizer and/or Braille display;
-
graphical rendering of the mathematical expressions. This feature aims to support communication between blind students and sighted people (e.g. school-mates, teachers, assistants, etc.).
-
printing of the document including text and mathematical expressions.
In recent years the system has been adopted by many Italian schools (primary schools, secondary schools and by some students at university).
This speech examines how the LAMBDA system is used by blind students in primary schools, secondary schools and early years of university. The analysis concerns the use of LAMBDA both by students and teachers.
