RT Journal Article SR Electronic T1 Change Blindness in 3D Virtual Reality JF bioRxiv FD Cold Spring Harbor Laboratory SP 025817 DO 10.1101/025817 A1 Madis Vasser A1 Markus Kängsepp A1 Jaan Aru YR 2015 UL http://biorxiv.org/content/early/2015/08/31/025817.abstract AB In the present change blindness study subjects explored stereoscopic three dimensional (3D) environments through a virtual reality (VR) headset. A novel method that tracked the subjects’ head movements was used for inducing changes in the scene whenever the changing object was out of the field of view. The effect of change location (foreground or background in 3D depth) on change blindness was investigated. Two experiments were conducted, one in the lab (n = 50) and the other online (n = 25). Up to 25% of the changes were undetected and the mean overall search time was 27 seconds in the lab study. Results indicated significantly lower change detection success and more change cycles if the changes occurred in the background, with no differences in overall search times. The results confirm findings from previous studies and extend them to 3D environments. The study also demonstrates the feasibility of online VR experiments.
