The aim is to develop a method for obtaining anthropometric parameters using a low cost three-dimensional digitizer. The research methodology is divided in five steps: literature review; collection and analysis of anthropometric data using the direct method and also the development of the indirect method for obtaining anthropometric measurements; comparison and data analysis; discussion of results and the completion of the research. The digitization process developed it is based on Microsoft Kinect, a low-cost device, and also on the software kscan3D. For the anthropometric collection from the three-dimensional model is used Autodesk 3D Studio Max. This research presents requirements and constraints for generate the three-dimensional model in order to obtain a mesh with satisfactory precision. It is presented a flowchart to guide the implementation of the developed method in the design process as well as a summary table containing guidelines for this application. The developed method achieved 97.96% of compatibility considering the results of the measured variables in relation to the direct method. These results were obtained with an exposure time of the individual of only 3 minutes and 28 seconds, which is less than the time required in the direct method – 1 hour and 12 minutes. This demonstrates one major contribution of the developed method.

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.

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.

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.

This article investigates the systematization of technical education in “graphic design”, issues related to curriculum and to structuring guidelines of technical courses at secondary level, and also its technological area. It also explains the use of specific nomenclature in each mode of education, the relations of the verticalization of technical education at secondary level, according to the Ministry of Education and considerations related to professional occupations listed in the Brazilian Classification of Occupations of the Ministry of Labor and Employment. The article also explores the national and international scientific competitions, associated with professional education at secondary level often entitled Knowledge Olympics or Professional Training Tournaments. The information presented uses the National Catalogue of Technical Courses proposed in 2008, the Brazilian Classification of Occupations, the Knowledge Olympics guidelines developed and organized by the National Service of Industrial Education, and the rules and guidelines of the International Tournament of Professional Training - WorldSkills Competition- as a checking basis. In addition, the study aims to reflect on a contribution to the labor market and also to the technological, scientific and cultural development of the society through the verticalization of technical education supported by scientific competitions in the graphic design field.

The present study focused on the inclusion of visually impaired individuals in regular and special
need education based on the proposal of educational resources to be applied in different
disciplines. This study case involved the development of models of nanostructured systems. The
production of these models included image design and stylization, 3D virtual modeling and 3D
print. The representation techniques used in this study generated a didactic kit for the teaching of
nanostructured systems. The proposed models can be used for both sighted and visually impaired
students, whether blind or with low vision.

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 design-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.

O presente artigo traz reflexões sobre como o projeto de moda pode ser pensado com o viés da sustentabilidade ambiental, contemplando alguns conceitos e ações do setor têxtil e de confecção. Foi realizada uma simulação de produção de um modelo de blusa feminina levando em consideração os conceitos de redução de resíduo na fonte por meio de modificações simples no produto. Desta forma, foram elaborados os desenhos, modelagens, encaixes e cálculos de tecidos e mão de obra para que fossem comparados os custos de produção e de geração de resíduos têxteis em cada um dos modelos. Os resultados mostram que as modificações reduziram consideravelmente a quantidade de resíduos na etapa de corte de tecidos, embora tenham acarretado no aumento dos custos com mão de obra.

Education systems are undergoing transformations in order to adapt their curriculum to develop skills that are required of professional from courses that have design disciplines. Also increasingly evident is the need for a transdisciplinary teaching that involves collaboration among different disciplines of the same science. In this context, this article focuses, by the case study of synthetic diamond particles, on the integration among Descriptive Geometry, Technical Drawing, Materials and Processes disciplines with the aid of CAD systems. Through this integration and a transdisciplinary teaching, it is possible to correlate the knowledge that involves three-dimensional modeling, the projection of objects and analysis of the geometric shape. The generated models represent an innovative feature for the process of teaching and learning in the disciplines that involve the design as it provides an effective contact between the student and the object of study through, the manufacturing experience and the concrete three-dimensional experience.
