Dados obtidos com o Censo Demográfico, em 2010, revelaram que quase 24% da população brasileira possuem algum tipo de deficiência, sendo a deficiência visual a de maior ocorrência. Dentre as políticas sociais que buscam atender às diferentes necessidades dos cidadãos, vale destacar o direito universal à educação. Recursos didáticos de diferentes naturezas vêm sendo empregados como ferramenta para auxiliar o ensino-aprendizagem de pessoas com deficiência visual. Vale, porém, questionar se esses recursos são realmente eficazes na compreensão de determinados conteúdos? Assim, o presente trabalho propõe a validação de modelos didáticos 3D para permitir a compreensão de sistemas nanoestruturados por deficientes visuais. A avaliação dos modelos foi realizada por usuário cego e, para tanto, foi utilizada uma adaptação do instrumento SETT (Alunos, Ambiente, Tarefas e Ferramentas). Os resultados indicam que os modelos produzidos por impressão 3D necessitam de revisão no que tange à legenda em Braille, mas, quanto aos demais aspectos, são viáveis para o uso como recurso didático para alunos com deficiência visual.

This paper presents the main contributions of the research group Virtual Design (ViD) to the learning process of Descriptive Geometry (DG) in line with the principles of project-based learning. First, the paper presents the theoretical framework that bases the main ViD initiatives applied to the learning of DG, including design-based learning and physical and virtual modelling. The initiatives presented include a learning cycle based on concrete and virtual experiences in the design context. These initiatives that feed the learning of DG are the result of academic research of the Virtual Design research group, also involving Masters and PhD projects, with repercussions on the development of new methods, new technologies and new products, and the quality of education.

The goal this article is to show an alternative to the process of making orthoses of a lower limb through of 3D scanning system of cost low. This alternative eliminates the plaster process traditionally utilized in the manufacture of orthoses of the lower limb. Therefore, was done an analysis of the manufacturing process orthoses in a specialist manufactory in a Porto Alegre – RS city. After that was done a 3D scanning in a subject for verification of possibility to make a virtual 3D model of the scanned leg. The 3D scanner utilized during the 3D scanning process was the Kinect device of the Microsoft. Thus, the manufacturing process orthoses by 3D scanning obtained satisfactory results, may be a solution for replaced of plaster model in the manufacturing process. The work is in progress for verification and analysis of precision between the plaster models and virtual model obtained through of the low-cost 3D scanning system.
