Holographic Parallax Improves 3D Perceptual Realism
CoRR(2024)
Abstract
Holographic near-eye displays are a promising technology to solve
long-standing challenges in virtual and augmented reality display systems. Over
the last few years, many different computer-generated holography (CGH)
algorithms have been proposed that are supervised by different types of target
content, such as 2.5D RGB-depth maps, 3D focal stacks, and 4D light fields. It
is unclear, however, what the perceptual implications are of the choice of
algorithm and target content type. In this work, we build a perceptual testbed
of a full-color, high-quality holographic near-eye display. Under natural
viewing conditions, we examine the effects of various CGH supervision formats
and conduct user studies to assess their perceptual impacts on 3D realism. Our
results indicate that CGH algorithms designed for specific viewpoints exhibit
noticeable deficiencies in achieving 3D realism. In contrast, holograms
incorporating parallax cues consistently outperform other formats across
different viewing conditions, including the center of the eyebox. This finding
is particularly interesting and suggests that the inclusion of parallax cues in
CGH rendering plays a crucial role in enhancing the overall quality of the
holographic experience. This work represents an initial stride towards
delivering a perceptually realistic 3D experience with holographic near-eye
displays.
