论文摘要
人类视觉系统使用许多提示来深度感知，包括差异，适应性，运动视差和遮挡。它有责任虚拟现实性显示，以满足这些线索以提供身临其境的用户体验。多焦点显示，这是满足住宿提示的经典方法之一，将虚拟内容放在多个焦点平面上，每个焦点都处于不同的深度。但是，靠近眼睛的焦平面上的内容不会阻塞较远的人。这会恶化闭塞提示，并减少由于散焦模糊泄漏而导致深度不连续的对比度。本文可以使用新型的Conetilt操作员来启用咬合感知的多灶性显示器，该显示器提供了额外的自由度 - 倾斜在显示面板的每个像素上发出的光锥。我们表明，对于具有相对简单的遮挡散布的场景，倾斜光锥提供与物理遮挡相同的ect。我们证明，只有相位的空间光调制器可以轻松实现conetilt。使用实验室原型，我们显示的结果证明了遮挡线索的存在以及在深度边缘处显示的对比度增加。
The human visual system uses numerous cues for depth perception, including disparity, accommodation, motion parallax and occlusion. It is incumbent upon virtual-reality displays to satisfy these cues to provide an immersive user experience. Multifocal displays, one of the classic approaches to satisfy the accommodation cue, place virtual content at multiple focal planes, each at a di erent depth. However, the content on focal planes close to the eye do not occlude those farther away; this deteriorates the occlusion cue as well as reduces contrast at depth discontinuities due to leakage of the defocus blur. This paper enables occlusion-aware multifocal displays using a novel ConeTilt operator that provides an additional degree of freedom -- tilting the light cone emitted at each pixel of the display panel. We show that, for scenes with relatively simple occlusion con gurations, tilting the light cones provides the same e ect as physical occlusion. We demonstrate that ConeTilt can be easily implemented by a phase-only spatial light modulator. Using a lab prototype, we show results that demonstrate the presence of occlusion cues and the increased contrast of the display at depth edges.
