Increased reality applied to the teaching of the descriptive geometry

Abstract

Augmented reality allows students to visualize tridimensional shapes by turning and handing them in the palm of their hand. Taking objects "away" from the computer improves the students' perception of the three projection planes. A pedagogical application was designed with this new representation tool. Tridimensional models were made using the Google Sketchup open license software to view these 3D models using augmented reality. Handling the 3D models by students improves the clarity of tridimensional perception. The project also allowed for the assessment of pedagogical aspects, including the ways through which students improve their learning experience and how teachers can use these tools to build a more interactive setting where students can play an active role in the construction of their own learning environment.
