“…Kalia proposes an interactive depth of focus blur method to improve depth perception. 16 If the object is in shadow, it is further from the light source. Shadows of the objects on the ground help users perceive the objects' relative positions by connecting them to the ground plane.…”

The virtual reality (VR) and augmented reality (AR) applications have been widely used in a variety of fields; one of the key requirements in a VR or AR system is to understand how users perceive depth in the virtual environment and AR. Three different graphics depth cues are designed in shuffleboard to explore what kind of graphics depth cues are beneficial for depth perception. We also conduct a depth‐matching experiment to compare performance in VR and AR systems using an optical see‐through head‐mounted display (HMD). The result shows that the absolute error increases as the distance becomes farther. Analysis from the inverse of distance shows that box depth cues have a significant effect on depth perception, while the points depth cues and line depth cues have no significant effect. The error in diopter in AR experiment is lower than that in VR experiment. Participants in the AR experiment under medium illuminance condition have less error than those under low and high illuminance conditions. Men have less error than women in certain display conditions, but the advantage disappears when there is a strong depth cue. Besides, there is no significant effect of completion time on depth perception.

“…These findings can also be used to improve applications if distinct depth perception of objects is required. Kalia et al [24] implemented an excellent example in which they used warm colors to represent closer objects and cool colors to represent further objects in medical images displayed on a desktop monitor. Our findings could help improve such an application where developers want to further emphasize depth using depth cues.…”

“…This experiment provided useful insights on brightness as a depth cue for head-worn AR, but we are interested in handheld mobile AR. Kalia et al [24] expressed motivation to improve depth perception in AR medical imaging applications. They combined color cues with depth of focus blur and found that using warm colors for close objects and cool colors for far objects improved perception.…”

“…Singh et al [47] have also conveyed the importance of accurate depth perception in AR and provided examples of AR applications that require depth matching between real and virtual objects. Similarly, Kalia et al [24] remarked that inaccurate depth perception poses a problem in medical AR applications and causes difficulty for users. Hebborn et al [22] have also expressed how inaccurate rendering of virtual objects often breaks the illusion of co-existence in AR applications, further providing compelling reasons to ensure that depth perception of virtual objects is accurate.…”

Depth perception of objects can greatly affect a user's experience of an augmented reality (AR) application. Many AR applications require depth matching of real and virtual objects and have the possibility to be influenced by depth cues. Color and luminance are depth cues that have been traditionally studied in two-dimensional (2D) objects. However, there is little research investigating how the properties of three-dimensional (3D) virtual objects interact with color and luminance to affect depth perception, despite the substantial use of 3D objects in visual applications. In this paper, we present the results of a paired comparison experiment that investigates the effects of object shape, fidelity, color, and luminance on depth perception of 3D objects in handheld mobile AR. The results of our study indicate that bright colors are perceived as nearer than dark colors for a high-fidelity, simple 3D object, regardless of hue. Additionally, bright red is perceived as nearer than any other color. These effects were not observed for a low-fidelity version of the simple object or for a more-complex 3D object. High-fidelity objects had more perceptual differences than low-fidelity objects, indicating that fidelity interacts with color and luminance to affect depth perception. These findings reveal how the properties of 3D models influence the effects of color and luminance on depth perception in handheld mobile AR and can help developers select colors for their applications.
