“…However, none of those cues is singularly responsible for the underperception that characterizes distance perception in VEs. Recent research using newer HMDs has reported nearveridical judgments of egocentric distance (Li, Zhang, & Kuhl, 2014;Young, Gaylor, Andrus, & Bodenheimer, 2014), but the reason for the reported differences between HMDs is unknown. Distance judgments in the VE conditions of Li et al (2013;experiment 2) were larger than those in the current experiment.…”

“…Research on perception of distance indicates that perceived distance is foreshortened in virtual compared to real environments (see Renner et al (2013) for a review), although this difference is narrowing with more modern displays (Buck et al 2018;Creem-Regehr et al 2015;Li et al 2014;Kelly et al 2017). Perception-action couplings have also been studied in the context of virtual environments (Kuhl et al 2008;Mohler et al 2007), but none to our knowledge have directly compared such couplings in matched real and virtual environments.…”

Vision in real environments stabilizes balance compared to an eyes-closed condition. For virtual reality to be safe and fully effective in applications such as physical rehabilitation, vision in virtual reality should stabilize balance as much as vision in the real world. Older virtual reality technology was previously found to stabilize balance but by less than half as much as real-world vision. Recent advancements in display technology might allow for vision in virtual reality to be as stabilizing as vision in the real world. This study evaluated whether viewing a virtual environment through the HTC Vive-a new consumer-grade head-mounted display-stabilizes balance, and whether visual stabilization is similar to that provided by real-world vision. Participants viewed the real laboratory or a virtual replica of the laboratory and attempted to maintain an unstable stance with eyes open or closed while standing at one of two viewing distances. Vision was significantly stabilizing in all conditions, but the virtual environment provided less visual stabilization than did the real environment. Regardless of the environment, near viewing led to greater visual stabilization than did far viewing. The smaller stabilizing influence of viewing a virtual compared to real environment might lead to greater risk of falls in virtual reality and smaller gains in physical rehabilitation using virtual reality.

“…Other methods use a "computer vision" approach applying perspective projection adjustments: Minification is a method which compresses the imaginary to artificially increasing the FOV of a display, and its application can improve distance perception ( [8], [28], [10]). Lowering the horizon is another similar method which had good results ( [14], [19]).…”

Abstract. The interception of the action-perception loop in virtual reality [VR] causes that understanding the effects of different display factors in spatial perception becomes a challenge. For example, studies have reported that there is not size-constancy, the perceived size of an object does not remain constant as its distance increases. This phenomenon is closely related to the reports of underestimation of distances in VR, which causes remain unclear. Despite the efforts improving the spatial cues regarding display technology and computer graphics, some interest has started to focus on the human side. In this study, we propose a perceptual calibration method which can ameliorate the effects of non-size-constancy in heterogeneous VR displays. The method was validated in a perceptual matching experiment comparing the performance between an HTC Vive HMD and a four-walls CAVE system. Results show that perceptual calibration based on interpupillary distance increments can solve partially the phenomenon of non-size-constancy in VR.
