The information presented by augmented reality (AR) systems may not appear exactly like information perceived in the “real” world. Shortfalls in AR technology give rise to anomalies like tracker errors, lack of opacity compared to the background, and reduced field of view (FOV) compared to the human visual system’s field of view. These anomalies can make users feel like the information presented in an AR training system is not believable. This lack of belief can lead to negative training, where trainees adjust how they train due to flaws in the training system and are therefore less prepared for actual battlefield situations. We have completed an experiment to investigate trust, reliance, and human task performance in an augmented reality three-dimensional experimental scenario. Specifically, we used a methodology in which simulated real (complex) entities were supplemented by abstract (basic) cues presented as overlays in an AR head-worn display (HWD) for a visual search and awareness task. We simulated shortfalls of different AR display systems to determine which of the properties most affect training efficacy. Results from our experiment will feed directly into the design of training systems that use AR displays and will help increase the efficacy of training.
