From 2D to 3D: Teaching terrain representation in engineering studies through Augmented reality: Comparative versus 3D pdf

Engineering students have got great skills in the use of new technologies, but large deficiencies in terms of the ability to visualize three-dimensional models shown in two dimensions. Also, the spatial capabilities are critical to them, to achieve the further development and understanding of associated complex, linked contents and competencies. However, it is difficult to illustrate the relationship between the 3D geometry and 2D projection using only drawings on blackboard. A new way to show these concepts is needed. Since Augmented reality (AR) and 3D pdf are the low-cost technologies that could easily display the relationship between two-dimensional displayed representations and the object shown. This paper presents early results conducted through the education innovation project Pol+AR. This project aims to determine the 3D-2D connection, using models, based on AR and 3D pdf, improving the spatial visualisation ability in students, specifically in the study of surveying and its applications, knowledge of the contour lines, earthworks and profiles. Studies have been developed in VET, at CFGS Proyectos de Edificación, (Building projects), at IES Politécnico Jesús Marín of Málaga. Finally, the implementation of this research will be carried out at Universidad de Málaga, Escuela Politécnica Superior.
