Enhancing subject matter assessments utilizing augmented reality and serious game techniques

In this paper, we utilize the Microsoft HoloLens, a wearable augmented-reality (AR) device, to investigate how well an AR-based assessment tool measures a student's comprehension of, skill in, and aptitude for a given subject matter. We added assessment capabilities to a serious game prototype built in collaboration with Construction Management faculty for their Occupational Safety and Health Administration (OSHA) safety course. In an effort to verify if these assessment elements are effective, we hosted a trial with sixteen university students who were enrolled in the OSHA safety course. The trial consisted of a traditional pen-and-paper exam and an AR-based assessment. The AR-based assessment required the students to identify unsafe situations of virtually simulated workers, construction equipment, and/or vehicles in an AR diorama of an active construction site. We selected OSHA topics from eight categories ranging from proper ladder usage on the work site to workers wearing the correct protective equipment for where they are and what they're doing. We find that 1.) students who performed well on a paper-based assessment also performed well within the AR-based assessment tool, 2.) students and faculty considered the AR trial more comprehensive and representative of knowledge, and 3.) user feedback reinforced the visual and interactive benefits of the AR over the paper-based exam. This trial shows promising results to adapt serious games and AR assessments into Computer Science and interdisciplinary subject matters that rely on visualization and spatial understanding.
