Construct3D: A Virtual Reality Application for Mathematics and Geometry Education


Project duration: 1999-
Contact: Hannes Kaufmann, Dieter Schmalstieg

Description

Construct3D is a three dimensional geometric construction tool based on the collaborative augmented reality system „Studierstube". Our setup uses a stereoscopic head mounted display (HMD) and the Personal Interaction Panel (PIP) – a two-handed 3D interaction tool that simplifies 3D model interaction. Means of application in mathematics and geometry education at high school as well as university level are being discussed. A pilot study summarizes the strengths and possible extensions of our system. Anecdotal evidence supports our claim that the use of Construct3D is easy to learn and encourages experimentation with geometric constructions.

Problem

Our aim was not to create a professional 3D modelling package but rather a simple and intuitive 3D construction tool in an immersive virtual environment for educational purposes. Our main goal was to keep the user interface as simple as possible to facilitate learning and efficient use. The main areas of application of our system in mathematics and geometry education are vector analysis, descriptive geometry and geometry in general. These areas have not been specifically addressed by previous systems.

Approach

We discuss what was learned from the difficulties that arose during the implementation process. The results of our pilot study with geometry students actually using Construct3D are presented with an emphasis on suggested improvements and new techniques that can be applied within other virtual worlds. A discussion with emphasis on the implications and practical significance of the findings and their limitations follows.

Images & Results

During our pilot study with 14 participants we took several photos and composed some images of students working with Construct3D.
