增强现实（AR）是一种新兴技术，其中信息直接在观察者面前叠加到真实的世界上。AR图像可能表现为干扰物，因为它们在观察者的视场内，并且可能导致观察者忽略真实的世界中的重要信息。这种对事件或物体的忽视被称为“变化盲视”。在变化盲视中，干扰物可能会导致某人忽略原始图像和修改后的图像之间的变化。在本研究中，我们调查是否发生变化盲视时，AR是使用和AR呈现方法是否影响变化盲视。在典型的闪烁范例中，将AR图像作为分心物双眼或单眼呈现。在双眼呈现中，AR图像被呈现给参与者的双眼，因此，它与典型的闪烁范例没有不同。相比之下，在单眼呈现中，AR图像仅呈现给一只眼睛。因此，假设如果参与者可以通过未呈现AR图像的眼睛观察真实世界图像，则可以避免变化盲视，因为可以观察到变化的时刻本身。此外，由于AR图像是半透明的，因此预期AR图像的亮度会影响观察真实的世界的容易性。因此，AR干扰器有三个亮度条件（高，中，低），我们比较了需要多少交替来检测条件之间的变化。结果表明，在双眼视觉和高亮度条件下，需要更多的交替。然而，在单眼呈现的所有亮度条件下，检测变化所需的交替次数与未呈现AR干扰项时的交替次数没有显著差异。这一结果表明，单眼呈现可以减轻变化盲视，这可能是因为观察者的视觉注意力被自动吸引到变化发生的位置。
Augmented reality (AR) is an emerging technology in which information is superimposed onto the real world directly in front of observers. AR images may behave as distractors because they are inside the observer's field of view and may cause observers to overlook important information in the real world. This kind of overlooking of events or objects is known as "change blindness." In change blindness, a distractor may cause someone to overlook a change between an original image and a modified image. In the present study, we investigated whether change blindness occurs when AR is used and whether the AR presentation method influences change blindness. An AR image was presented binocularly or monocularly as a distractor in a typical flicker paradigm. In the binocular presentation, the AR image was presented to the both of the participants' eyes, so, it was not different from the typical flicker paradigm. By contrast, in the monocular presentation, the AR image was presented to only one eye. Therefore, it was hypothesized that if participants could observe the real-world image through the eye to which the AR image was not presented, change blindness would be avoided because the moment of change itself could be observed. In addition, the luminance of the AR image was expected to influence the ease to observe the real world because the AR image is somewhat translucent. Hence, the AR distractor had three luminance conditions (high, medium, and low), and we compared how many alternations were needed to detect changes among the conditions. Result revealed that more alternations were needed in the binocular presentation and in the high luminance condition. However, in all luminance conditions in the monocular presentation, the number of alternations needed to detect the change was not significantly different from that when the AR distractor was not presented. This result indicates that the monocular presentation could attenuate change blindness, and this might be because the observers' visual attention is attracted to the location where the change has occurred automatically.
