Abstract

In the accessibility area of disabled people there is much lack of computational resources provided support to primary education, access to universities and digital inclusion in the labor market. This work plan is designed to support the visually impaired geometrical understanding and treatment of mathematical functions, geometric figures and graphics.In the world there are few discussions, in particular concerning in the treatment of mathematical functions, there are not anything that can provide visually impaired people concept of space graph behavior of these functions and even its analysis. When we talk about the interpretation of geometrical figures very little thing were studied, that exists in this sense are few studies of the interpretation of spatial relief by Braille printing.This study aims at the same level, develop two lines of separate but interconnected research methodology and objectives. One line geared specifically to the treatment of mathematical functions, its obtaining, mathematical analysis and graphical visualization. The other line is directed to geometric treatment and graphic interpretation of geometric figures and graphics in general. (AU)
