虽然新兴的虚拟和增强现实（VR/AR）系统可以产生高度身临其境的体验，但它们也会导致视觉不适、眼睛疲劳和恶心。这些症状的来源之一是汇聚和聚焦线索之间的不匹配。在当前的VR/AR近眼显示中，立体图像对驱动人类视觉系统的收敛状态到任意距离，但眼睛的调节或聚焦状态是光学驱动到固定距离。在这项工作中，我们引入了一种新的显示技术，称为调节不变（AI）近眼显示，以提高近眼显示中深度线索的一致性。人工智能显示器不是产生正确的焦点线索，而是通过光学工程来产生与眼睛调节状态不变的视觉刺激。然后调节系统可以由立体线索驱动，并且在收敛和调节状态之间的不匹配的眼睛显著减少。我们使用一个原型显示器验证了人工智能显示器的操作原理，该原型显示器允许在用户使用多种不同的显示模式查看视觉刺激时测量用户的适应状态。
Although emerging virtual and augmented reality (VR/AR) systems can produce highly immersive experiences, they can also cause visual discomfort, eyestrain, and nausea. One of the sources of these symptoms is a mismatch between vergence and focus cues. In current VR/AR near-eye displays, a stereoscopic image pair drives the vergence state of the human visual system to arbitrary distances, but the accommodation, or focus, state of the eyes is optically driven towards a fixed distance. In this work, we introduce a new display technology, dubbed accommodation-invariant (AI) near-eye displays, to improve the consistency of depth cues in near-eye displays. Rather than producing correct focus cues, AI displays are optically engineered to produce visual stimuli that are invariant to the accommodation state of the eye. The accommodation system can then be driven by stereoscopic cues, and the mismatch between vergence and accommodation state of the eyes is significantly reduced. We validate the principle of operation of AI displays using a prototype display that allows for the accommodation state of users to be measured while they view visual stimuli using multiple different display modes.
