Paper Abstract:
|
This paper builds on the review of related work, methodology and partial results presented in a previous work for presents the final results obtained of an innovator program designed primarily aiming at people with visual impairments in the development of geometric figures, as well as a simple example of its use. The geometry is very likely to challenge not only students with visual impairments, but also sighted students and their teachers in the approach of teaching them. As this area of mathematics is crucial in most disciplines of science, this limited study options and future job opportunities. However, it can be said that there is not any reason why the geometry cannot be understood because of blindness, but the biggest barrier is access to geometric content. The development of skills and understanding in many topics depend upon on their spatial sense/perception. Spatial properties and relations include shape, size, distance, orientation and relative location. Manipulation of objects in space also provides background for understanding algebra, trigonometry, calculus and many other topics in higher mathematics that require spatial thinking. Spatial sense is an intuitive feel for shape and space. It involves the concepts of traditional geometry, including an ability to recognize, visualize, represent, and transform geometric shapes. This application was created to supply the needs required by visually impaired about designing, drawing and printing of geometric figures in Braille, with reliefs independently. The program allows access to create and print geometric designs, tasks that until now were not available to visual impairments people. The application treats the creation of projection and geometric wizards from own parameters using a speech synthesizer and wizards or special menus oriented to visually impaired individual. Subsequently, the application enables easy printing from geometrical shapes on the same sheet just in Braille, as in reliefs. |
