VirtualHoP: Virtual Worlds for experimentation and concretization of technical drawing

This work proposes the adoption of 3D Virtual Worlds for providing younger students with an environment capable of supporting the engineering practices based on technical drawing. The main difficulty of technical drawing consists in representing a 3D object on a 2D medium. This restriction imposes to human mind to be able to summarize the spatial properties of objects on the paper. The proposed system trains these capabilities by requiring students to build in the simulated environment simple objects represented with 2D drawings. In this way, the students are not only pushed to move themselves between different dimensionality spaces, but also they benefit of the 3D spaces for moving and exploring the models they are building.
