摘要

当三维渲染内容的双眼差距(辐辏)与显示焦距(调节)不一致时,近眼显示屏就会出现辐辏-调节冲突(VAC)。研究表明,VAC 会降低感知图像质量、认知能力和眼球运动协调能力。在这项研究中,我们旨在调查 VAC 对增强现实(AR)中视觉表现的影响。具体来说,我们量化了 AR VAC 对 "聚焦时间"(TTF)的影响;当用户在现实世界的内容和锁定世界的 AR 渲染内容之间切换焦点时,TTF 会发生变化。我们的结果表明,TTF 会随着 VAC 的增加而呈指数增长。在焦距为 1 D 或更远的显示器中,当辐辏距离更近时,TTF 的增加更为明显。最后,我们还发现,VAC 可能会对不同年龄段的用户产生不同的影响;具体来说,年龄较大的用户在焦距较近和辐辏距离较长的情况下受到的影响可能更大。

Vergence-accommodation conflict increases time to focus in augmented reality

Vergence-accommodation conflict increases time to focus in augmented reality

Vergence-accommodation conflicts (VAC) occur in near-eye displays when the binocular disparity of the 3D rendered content (vergence) does not match the display focal distance (accommodation). VAC has been shown to reduce perceptual image quality, cognitive performance, and oculomotor coordination. In this study, we aimed to investigate the impact of VAC on visual performance in augmented reality (AR). Specifically, we quantified the impact of AR VAC on the ‘Time to Focus’ (TTF); when the user switches focus between real-world content and world-locked AR-rendered content. Our results show that TTF increases exponentially with VAC. The increase is more pronounced at closer vergence distances in displays with a focal distance of 1 D or longer. Finally, we showed that VAC may have a differential effect across age groups; specifically, older users may be affected more in closer focal and longer vergence distances.

期刊介绍: The Journal of the Society for Information Display publishes original works dealing with the theory and practice of information display. Coverage includes materials, devices and systems; the underlying chemistry, physics, physiology and psychology; measurement techniques, manufacturing technologies; and all aspects of the interaction between equipment and its users. Review articles are also published in all of these areas. Occasional special issues or sections consist of collections of papers on specific topical areas or collections of full length papers based in part on oral or poster presentations given at SID sponsored conferences.
