Teixeira, F. G., "Perspectivas axonométricas e vistas principais no ensino de geometria descritiva", Revista Educação Gráfica, vol. 20, pp. 289 - 302, 2016. AbstractFull Text

This work present axonometric and orthographic views to learning of Descriptive Geometry concepts. Axonometric views are a good way to show the utility of successive auxiliary views because they present the process and promote the 3D comprehension of objects. The paper proposes ways to build axonometric projections from any point of view by Descriptive Geometry tools. Besides, the use of the principal views enhances the understanding of successive auxiliary views, but in a more complex context where the student must choose directions to find the correct projections. Through these directions, you can choose the sequence of auxiliary planes that result in orthographic views. This work shows how two unusual concepts in the Descriptive Geometry education context can promote a better understanding of many of its contents.

The aim of this paper is comparing both tridimensional scanners: white light Artec Eva; and Infra-red light Microsoft Kinect. This comparison enables evaluate possibilities of these equipments for developing user-centered product projects. It was carried out comparison's concerning both precision and dimensional deviation through virtual and physical models generated by CAD and CAM systems. It was verified the need of eliminating the human body movement by using physical models in the performed analysis. As a result, both scanners demonstrated measurement precision, with the advantage of Artec Eva over Microsoft Kinect. The selection of the most appropriated scanner concerning the projects needs evolves factors such as: the available cost for the project; and the required precision fidelity for the aimed product. Both digital scanners considered in this paper contribute to the development of customized products, showing the relationships between tools and needed product fidelity.

Rossi, "FABRICAÇÃO DIGITAL PARA AUXILIAR NO ENSINO-APRENDIZADO DE ALUNOS COM DEFICIÊNCIA VISUAL: ESTUDO DE CASO DOS SISTEMAS NANOESTRUTURADOS", 12º Congresso Brasileiro de Pesquisa e Desenvolvimento em DesignBlucher Design Proceedings, vol. 12, Belo Horizonte, pp. 2389 - , 06 de outubro, 2016. Abstract

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.

Teixeira, F. G., "UM MODELO EVOLUTIVO PARA O PROCESSO DE GERAÇÃO E SELEÇÃO DE ALTERNATIVAS EM DESIGN", 12º Congresso Brasileiro de Pesquisa e Desenvolvimento em DesignBlucher Design Proceedings, vol. 12, Belo HorizonteSão Paulo, Editora Blucher, pp. 4374 - , 06 de outubro, 2016. Abstract

The conceptual design step is the most complex of the design process and brings great challenges to designers. The number of possible concepts from a combination of functional principles can reach millions. This could derail an exhaustive search for the best possible concepts. So, this work proposes an evolutionary approach to that problem. The result is a framework based on a Genetic Algorithm (GA) that combines the specific properties of the design process with the core of GA, improving this process as a natural evolution.

The purpose is to evaluate models obtained by different 3D scanning systems, and that the geometric variations can generate implications for anthropometric measurements for custom product design. For comparison and analysis, the right leg of a subject was scanned by white light 3D scanner (Artec Eva) and the infrared scanner (Microsoft Kinect). 3D models obtained by the scanners were compared using the Geomagic Qualify software. Also, by CNC machining of visual comparisons were performed analysis, for pressure mapping and thermography. The results were satisfactory both for the use of Kinect scanner and for Artec Eve. However, there was a dimensional difference of about 7 mm between the 3D models, which shows higher accuracy measures the models obtained by Eve Artec scanner. However, does not invalidate the use of Kinect for developing custom product designs. What will determine the most suitable for each type 3D scanner product is the degree of accuracy necessary for the product to perform its function with greater comfort and efficiency.

Viaro, F. S., F. G. Teixeira, R. P. da Silva, and S. L. Sapper, "Da ideia ao conceito de produto: o uso de técnicas criativas combinadas para auxiliar no processo de desenvolvimento de novos produtos de design", Estudos em Design (Online), vol. 23, pp. 49 - 60, 2015. AbstractFull Text

A criatividade é um fator essencial para a competitividade dos produtos e o sucesso das empresas. Existe uma série de técnicas criativas que podem ser utilizadas por equipes de projeto de produto. Porém, ocorrem dificuldades na aplicação sistemática dessas técnicas no momento de gerar as concepções de projeto. O objetivo deste trabalho é discutir o uso de técnicas criativas para a geração de ideias de produtos durante o Processo de Desenvolvimento de Produtos (PDP). Foi realizado um estudo experimental por meio do desenvolvimento de um produto que auxilie no transporte de crianças. O desenvolvimento do produto foi realizado até a etapa de projeto conceitual. Para isso, foi utilizado o jogo Creative Sketch na geração de ideias, assim como, técnicas de avaliação e seleção de concepções de projeto para eleger as concepções mais adequadas aos requisitos de projeto. A utilização do jogo possibilitou a geração de 72 ideias em um curto período de tempo. Além do jogo, utilizaram-se o método da síntese funcional e a técnica da matriz morfológica para a geração de alternativas, assim como o método de Pugh para a seleção das melhores alternativas. Como resultado desse processo obtiveram-se duas concepções de produto que atenderam aos requisitos de projeto estabelecidos. Palavras-chave: Criatividade, Técnicas para a geração de ideias, PDP, Jogo, Seleção de concepções.
