Mobile Edutainment with Interactive Augmented Reality Using Adaptive Marker Tracking

Augmented Reality (AR) is a great partner of Edutainment in motivating students and enriching a class. Students can check out additional digital information of physical items such as books, samples, exhibits or even sites. The information looks just like existing in the reality. In addition to a show of multimedia content, we opine that if the virtual objects augmented to the reality can act and react like real objects, the learning experience can be greatly promoted. We developed an AR system in that the virtual objects can interact with each others. We implemented several applications using the system to demonstrate the use of interactive AR in edutainment. We also attempted to resolve the limitation of image angle coming with vision-based AR by building a multi-marker mechanism using a cube structure with surface area approximation. We also discussed some challenges and issues that researchers or developers should take note of in pursuing AR development.
