视景渲染能否改善虚拟和增强现实中的深度感知?

Would Gaze-Contingent Rendering Improve Depth Perception in Virtual and Augmented Reality?

Paul Linton

摘要:

在虚拟现实中,近距离被高估,远距离被低估,但对这些扭曲的解释仍然难以捉摸。一个潜在的问题是,当眼睛旋转以观看虚拟场景时,虚拟相机保持静止。在虚拟现实中,当眼睛转动时,使用眼动跟踪来改变虚拟相机的视角是否可以改善深度感知?本文确定了14个不同的视角失真,理论上可能发生从保持虚拟相机固定,而眼睛旋转的上下文中的近眼显示。然而,眼睛运动对显示图像的影响取决于显示器的光学距离,而不是物理距离。由于大多数盔装显示器的光学距离超过1米,因此这些失真中的大多数将仅具有可忽略的影响。例外的是“视在眼内”,这将使附近的虚拟对象看起来与增强现实中相同距离的物理对象发生位移。

英文摘要:

Near distances are overestimated in virtual reality, and far distances are underestimated, but an explanation for these distortions remains elusive. One potential concern is that whilst the eye rotates to look at the virtual scene, the virtual cameras remain static. Could using eye-tracking to change the perspective of the virtual cameras as the eye rotates improve depth perception in virtual reality? This paper identifies 14 distinct perspective distortions that could in theory occur from keeping the virtual cameras fixed whilst the eye rotates in the context of near-eye displays. However, the impact of eye movements on the displayed image depends on the optical, rather than physical, distance of the display. Since the optical distance of most head-mounted displays is over 1m, most of these distortions will have only a negligible effect. The exception are 'gaze-contingent disparities', which will leave near virtual objects looking displaced from physical objects that are meant to be at the same distance in augmented reality.
