Abstract
Change blindness (CB) is a failure of change detection that occurs if a distractor is presented when the change occurs. In some previous studies, even though the distractor covered only some of the stimuli images, CB occurred. Therefore, augmented reality (AR), which is an emerging technology in which information is superimposed onto the real world, may lead to CB and may be dangerous in actual use. A monocular type of AR system may solve this problem. In this system, an AR image is presented monocularly. We investigated CB in a monocular AR and hypothesized that CB did not occur in the monocular condition. This is because a participant can observe the real world continuously by using the eye to which the AR image is not presented. On the other hand, in the binocular AR condition, CB seems to inevitably occur because previous studies revealed that CB occurs when a distractor is presented binocularly. We conducted a typical flicker paradigm CB task. An original image and a modified image were presented alternately and repeatedly without blanking until participants detected the change. The distractor was a semitransparent AR rectangle, and it was presented binocularly or monocularly. This monocular AR distractor is the most important difference compared as with previous studies, in which the distractor was presented in the real world binocularly. As we hypothesized, CB rarely occurred in the monocular condition. This result indicates that participants can choose information to detect changes in the eye to which the AR image is not presented before the information from both eyes is integrated. By contrast, in the binocular condition, CB occurred. This indicates that a monocular presentation can solve the CB in actual AR use. In order to detect a change, monocular continuous information is needed, and it does not have to be binocular.
