Design and Implementation of a Prototype Based in 2D Blocks with Multiple Shapes for Teaching Computer Programming to Visually Impaired Children

This paper proposes the implementation of a prototype based in physical 2D blocks with multiple shapes for teaching computer programming to visually impaired children. The image processing techniques used, the source code generation and compilation process, and design of human-machine interfaces are presented. The results showed that using space color change technique is possible to get a standard C++ code program since a development environment based in physical blocks where the compilation results can be communicated throws of voice. Finally, some examples of programs that can be implemented through the prototype and the corresponding conclusions are provided.
