Interactive Slide Navigation: An Approach for Manipulating Slides with Augmented Reality Markers
Muhammad Tahir · The Smart Computing Review · 2002
The use of PowerPoint slides is an interactive way of communication in a classroom environment. To make it more effective, different techniques for the manipulation, annotation, and navigation of slides have been utilized. We presented the use of Augmented Reality technology to manipulate, annotate and navigate through PowerPoint slides. We used Augmented Reality marker recognition techniques by employing an Augmented Reality ToolKit. We performed tests by analyzing Augmented Reality marker IDs and their translational and rotational gestures. We used 1) simple flat Augmented Reality markers, 2) finger Augmented Reality markers, 3) cube markers, 4) illuminated markers, and 5) retro-reflective markers to manipulate slides. The results indicate that finger Augmented Reality markers are easy to handle and perform better than other types of markers. Cube markers are especially helpful in performing rotational gestures, while illuminated and retro-reflective markers provide moderate results in comparison with simple flat markers. As far as we know, we are the first to use Augmented Reality technology for handling slides and providing the presenter with distant access to the presentation.
