Abstract:
Educational institutions demand cost-effective and simple-to-use augmented reality
systems. ARToolKit, an open-source computer tracking library for the creation of augmented reality
applications that overlay virtual imagery on the real world, is such a system. It uses a simple
camera and black-and-white markers printed on paper. However, due to inter-marker confusion,
if the marker distinctions are not ensured, the markers are often miss-recognized. This paper
presents an ARToolKit-based InteractiveWriting Board (IWB) with a simple mechanism for designing
confusion-free marker libraries. The board is used for teaching single characters of Arabic/Urdu
to primary level students. It uses a simple ARToolKit marker for the recognition of each character.
After marker recognition, the IWB displays the corresponding image, helping students with character
understanding and pronunciation. Experimental results reveal that the system improves students’
motivation and learning skills.
