“…Research to date suggests that display attributes can strongly influence the initiation/perception of s-bd and in this context it is possible that large, ultra high definition, screen formats (including curved screen profiles) may play an important role. In relation to display resolution, Masaoka et al [40] describe a controlled study in which participants reported on the sensation of 'realness' when presented with electronic images (exhibiting angular pixel resolutions in the range 19-155 cycles per degree) as compared to viewing corresponding physical objects. Monoscopic viewing of both forms of content was achieved via a synopter.…”

In the eighteenth century, techniques that enabled a strong sense of 3D perception to be experienced without recourse to binocular disparities (arising from the spatial separation of the eyes) underpinned the first significant commercial sales of 3D viewing devices and associated content. However following the advent of stereoscopic techniques in the nineteenth century, 3D image depiction has become inextricably linked to binocular parallax and outside the vision science and arts communities relatively little attention has been directed towards earlier approaches. Here we introduce relevant concepts and terminology and consider a number of techniques and optical devices that enable 3D perception to be experienced on the basis of planar images rendered from a single vantage point. Subsequently we allude to possible mechanisms for non-binocular parallax based 3D perception. Particular attention is given to reviewing areas likely to be thought-provoking to those involved in 3D display development, spatial visualization, HCI, and other related areas of interdisciplinary research.

“…The letter‐acuity task is a good measure because resolution can be described by one parameter: visual angle of letter stroke width. Other researchers have found that the use of high‐resolution imagery with pixel sizes smaller than 1 arcmin (equivalent to 20/20 acuity) or 0.5 arcmin (equivalent to 20/10) contributes to a greater sense of realism . Indeed in a series of experiments, Spencer et al found that observers could discriminate displays when pixel sizes were smaller than 0.5 arcmin .…”

240 Hz OLED technology properties that can enable improved image quality

et al. 2014

Large screen Organic Light Emitting Diode (OLED) technology is finally emerging as a technology ready for consumer use. OLED has a number of areas in which it can in principle be better than Liquid Crystal Displays (LCDs); two ways in particular are that OLED technology can achieve black levels that are much darker than LCDs, and the OLED pixels can switch extremely rapidly. These differences can permit OLED displays to outperform LCD under a number of conventional scenarios, but it can also enable some dramatically improved stereoscopic 3D (s3D) displays, including full‐resolution temporal multiplexing with more than two views. In this paper, we review a set of experiments evaluating the strengths and weaknesses of OLED technology in general with a particular emphasis on understanding how the strengths of OLED technology can be leveraged to maximize the performance of an s3D display system.

“…Thus, 20/20 vision corresponds to acuity of 30 cycles/deg., which is approximately ½ the maximum grating acuity. It should be noted that 20/20 is "normal" vision but many people have better than normal vision, either naturally or with glasses, as pointed out by Masaoka et al [19]; for example, 20/10 vision corresponds to optotype acuity of 60/cycles per deg.…”

We present a framework for assessing the interaction of display resolution, display size, and video compression in the context of visual acuity. We review retinal topology in the context of several kinds of acuity: reading (optotype) acuity; grating acuity; and hyperacuity. We show that display resolution and field-of-view combinations correspond to each level of visual acuity. We also show how quantization of spatial-frequency coefficients in video compression relates to each level of visual acuity.
