Light field visualization technology offers a glasses-free 3D experience that may be enjoyed by multiple observers simultaneously. The overall visual experience depends on a multitude of factors, among which is light ray density. In case of horizontal-only parallax displays, it defines the smoothness of the horizontal motion parallax, which is crucial to visualization quality. However, the perceived light ray density naturally depends on the viewing distance; the farther the observer is, the fewer light rays may address the two pupils, with respect to a single point on the screen. Research on this topic has already been initiated and the first results are now available in the scientific literature. However, the experiment, similarly to the vast majority of research efforts regarding the perceived quality of light field visualization, is built on the participation of individuals that are screened for normal vision. Yet a notable portion of potential future users would not pass such screening, particularly the Snellen chart on visual acuity. In this paper, we investigate the suitability of viewing distances for the future use cases of light field visualization from the perspective of users with reduced visual capabilities. The subjective tests evaluate contexts of passive visual consumption, such as a cinematic experience or an exhibition of cultural heritage. The selected use cases are not only assessed by their natural viewing distance intervals, but by closer and farther distances as well. The output of the research aims to extend the social inclusion of potential systems and services of light field visualization.

“…Tamboli et al [5][6][7] studied the effects of particular spatial distortions on perceived quality and how the synthesis of source views (i.e., replacing original views with synthesized ones, the quality of which may be lower due to inaccurate estimations) affect what the viewers perceive. In case of the latter, the more views were replaced, the more light field visualization quality was degraded.…”

“…Tamboli et al investigated the perceived quality of light‐field view synthesis, created a high‐angular‐resolution dataset for objective and subjective assessments, evaluated content features, and developed an objective light‐field quality metric with an angular component. The works recognize content angular resolution as one of the most vital quality factors, for both objective and subjective visual quality.…”

In this paper, we present the concept, the implementation, and the evaluation of our novel angularly continuous light-field format. We compared the subjective visual performance of our format with the perspective camera format through a series of subjective and objective tests. In our extensive subjective study, we used multiple absolute and comparative rating scales and various visual stimuli with different contents and angular resolutions. The perceived quality was assessed by a total of 36 test participants, who were separated based on their scientific expertise. The objective quality was evaluated through the degradations caused by three well-known compression methods. The obtained results indicate that our light-field format may outperform the conventional format, and it generally can provide at least equivalent visual quality. Furthermore, these findings open the way for data size optimization, without compromising the achieved level of perceived quality.
