摘要：In virtual environments (VEs) presented on flat screens, accurate egocentric distance perception is crucial for enhancing immersion. This study investigated depth of field-induced blur, typically perceived as an ordinal depth cue, to understand its role as a quantitative depth cue in VEs. We employed verbal judgment and position adjustment methods to quantify observers' egocentric distance perception across various depth of field settings (n = 30 participants). Our analysis also examined the interplay between blur and other depth cues. Results indicated that increased blur in VEs leads to a greater underestimation of distances. Moreover, blur operates as a relatively independent depth cue, showing minimal interaction with other cues. These findings address a gap in research on the independent role of depth of field as a quantitative depth cue in VEs. This contributes to the visual design of VEs and supports the enhancement of user experience in human-computer interactions.
