Face Validity of Various Display Methodologies in Conveying Spatial Awareness and Depth Perception

Abstract

The information conveyed through visual cues varies greatly depending on the display method. Digital images are often used as trial demonstratives and are a vital resource in the presentation and transfer of information to a jury during litigation. In the situation where depth perception and spatial awareness are a key factor in the understanding of a subject incident, immersive technology, such as virtual reality (VR), may provide a valuable alternative to traditional media forms. The aim of this study was to evaluate the efficacy of different display methodologies in conveying depth perception and spatial awareness during an “optical illusion” misstep and fall case. This study provides a quantitative characterization of participants’ responses to various display methodologies ranging from 2D photographs to a VR environment. Results indicate that individuals were able to perceive a larger number of visual cues when immersed in a three-dimensional virtual environment, giving them a more accurate representation of the scene.
