“…Unlike multi-view displays that rely on so-called "sweet spots" [26], which are evenly distributed positions in front of the display from which the same perspective with limited variations can be perceived, light field displays utilize the entire field of view (FOV) and provide a smooth, continuous parallax within. Light field displays are also often addressed as super multi-view (SMV) displays in the scientific literature [27][28][29].…”

Light field displays offer glasses-free 3D visualization, which means that multiple individuals may observe the same content simultaneously from a virtually infinite number of perspectives without the need of viewing devices. The practical utilization of such visualization systems include various passive and active use cases. In the case of the latter, users often engage with the utilized system via human–computer interaction. Beyond conventional controls and interfaces, it is also possible to use advanced solutions such as motion tracking, which may seem seamless and highly convenient when paired with glasses-free 3D visualization. However, such solutions may not necessarily outperform conventional controls, and their true potentials may fundamentally depend on the use case in which they are deployed. In this paper, we provide a review on the 3D interaction of light field displays. Our work takes into consideration the different requirements posed by passive and active use cases, discusses the numerous challenges, limitations and potentials, and proposes research initiatives that could progress the investigated field of science.

“…Most of the commercially available, stereoscopic as well as autostereoscopic, 3D displays concentrate on reproducing the binocular visual cue for single or multiple observers thereby giving the illusion of 3D [1]. However, a typical consumer display is not capable or has difficulty in reproducing other cues important for 3D vision, most notable one being the continuous head parallax [2].…”

“…Disadvantage of those lies in the fact that, typically, only one user is supported. Second way of achieving a reasonably convincing continuous parallax is by using so called light field (LF) displays [1,3,4].…”

The visualization capability of a light field display is uniquely determined by its angular and spatial resolution referred to as display passband. In this paper we use a multidimensional sampling model for describing the display-camera channel. Based on the model, for a given display passband, we propose a methodology for determining the optimal distribution of ray generators in a projection-based light field display. We also discuss the required camera setup that can provide data with the necessary amount of details for such display that maximizes the visual quality and minimizes the amount of data.

“…However, most such devices require the viewers to wear some sort of shutter-or polarization glasses, which is often regarded as an inconvenience. Recently, so-called multiview autostereoscopic displays (MADs) [1], [2] have become commercially available. These are able to project several views of a scene simultaneously -enabling a glasses-free 3D experience and a limited motion parallax effect in horizontal direction.…”

Over the last couple of years, multiview autostereoscopic displays (MADs) have become commercially available which enable a limited glasses-free 3D experience. The main problem of MADs is that they require several (typically 8 or 9) views, while most of the 3D video content is in stereoscopic 3D (S3D) today. In order to bridge this gap, the research community started to devise automatic multiview synthesis (MVS) methods. These algorithms require real-time processing and should be portable to end-user devices to develop their full potential. In this paper, we present a complete hardware system for fully automatic MVS. We give an overview of the algorithmic flow and corresponding hardware architecture, and provide implementation results of a hybrid FPGA/ASIC prototype -which is the first complete hardware system implementing image-domainwarping-based MVS. The proposed hardware IP could be used as a co-processor in a system-on-chip (SoC) targeting 3D TV sets, thereby enabling efficient content generation in real-time.
