A mixed reality learning environment for Geometry education

Abstract

This paper presents a mixed reality environment for geometry education. The proposed system consists of three main sub-components: The Geometry construction agent, which allows users to create objects in the 3D scene, a Collision Detection algorithm, which calculates the collisions between the virtual hand and the dynamical geometrical objects and the haptic interaction agent which is responsible for the haptic feedback returned to the user. The user can perform actions in the virtual environment using a haptic glove and create a scene out of geometrical objects. Stereoscopic view is supported and actions are visualized on a large screen so that many users can observe the actions. The system has been evaluated in secondary schools in Thessaloniki, Greece and the results have shown that users consider it very satisfactory in terms of providing a more efficient learning approach.
