Development of handheld augmented reality X-Ray for K-12 settings

Abstract

Mobile augmented reality is a next-generation interface for seamless ubiquitous learning. It offers many novel interactions that enable the visualization of digital information on real places and objects. These interactions require user-based testing for suitability in educational settings. One important interaction is augmented reality X-ray—providing an illusion to look inside objects. In this chapter, we implement augmented reality X-ray on a tablet computer by modifying the live video feed with computer graphics. Then, we evaluated our prototype based on the students’ perception of depth, legibility, and realism. Results show that augmented reality X-ray hampers legibility. However, it does not have a significant impact on the perception of depth and realism. In our interviews with teachers, we found that augmented reality X-ray is perceived to be useful because it promotes learning by experience. It has the potential to improve both student attention and motivation. However, the teachers require a high-quality lesson plan, and extra training to use augmented reality X-ray in the classroom effectively.
