Space Perception in Augmented Reality: Emerging Recommendations for Tailoring Distance Cues to Virtual Content in Augmented-Reality Applications

Augmented-reality (AR) displays render virtual content overlaid on the real world. AR offers great potential for Soldiers to immediately perceive relevant tactical information without the need to consult a physical map or other reference material, or divert their eyes away from the immediate environment. However, realizing the potential benefits of using AR requires that the conformal subset of virtual content is perceived in the correct physical location. Conformal virtual content must be correctly associated with the physical location, object, or person intended to be augmented. In this report, we provide emerging recommendations aimed at improving spatial perception of virtual content.
