Comparative assessment of spatial perception in augmented reality depending on the consistency of depth cues

Abstract

Recent developments in three-dimensional image display technologies for augmentation of reality have led to a growing interest towards spatial perception research. Research in this domain aims to describe the quality of viewing experience and discover potential benefits and limitations of new visualisation approaches intended for use in professional capacities. Precise perception and interpretation of digital spatial information is crucial for decision making in many professional areas, such as healthcare, education, aerospace, and defence.Human spatial perception relies on a combination of multiple information sources -the so-called depth cues [1]. The differences in perception are related to the availability and weight of depth cues. Binocular depth cues (retinal disparity and vergence) ensure the most accurate judgements about spatial relations between objects in the near field, although their contribution to spatial perception decreases with an increase in viewing distance [1,2]. Besides the availability of depth cues, their consistency plays an important role. For instance, accommodation and vergence cues provide the same information about the depth of an object in natural viewing [3].Today, there are different types of display systems used for the three-dimensional presentation of information

Prevalence of oculomotor changes following the near work in stereoscopic augmented reality

“…Considering the work of the visual system when viewing stereoscopic images via augmented reality headsets, most attention was previously devoted to investigating perceptual issues such as focus rivalry 12 and misjudgment of spatial relationships 1,13,14,15 . We revealed a decline of vergence and accommodation ability in about 40% of the group after the near work in stereoscopic augmented reality.…”
