Interactive Augmented Reality to Extend Students' Vector Experience

Abstract

First-year engineering students show difficulties in connecting basic vector algebra with manipulations using the graphical representation. Experiencing vectors in real applications can improve the process of learning vectors. Thus, we introduce a unique approach for using digital technologies, namely augmented reality. We utilized a video see-through head-mounted display to develop a vector manipulation tool enabling users to select and place virtual vectors in the real environment. The aim was to see how students react when experiencing vectors in augmented reality. After using the prototype, students answered a questionnaire about this experience. Results show that students experiences are positive and they are motivated to use the prototype in the course. Further, we investigated opinions about vector concepts from students in the trial group and other students attending the same course in vector algebra. The results indicate some differences in what students spontaneously associate with the concept vectors. Moreover, this study provides insights into how such investigations can be elaborated in the future.
