Abstract

Through the immense scientific efforts of the past two decades, light field visualization is now emerging in the industry, and commercial, everyday use cases are also expected to benefit from this glasses-free true 3D technology in the near future. While the technology itself may enable a natural 3D experience, there are, in fact, certain situations where visualization quality is not optimal. This can be due to the attributes of light field capture, transmission, compression, and numerous other factors that may degrade the perceived quality. However, the impact of such degraded quality fundamentally depends on the actual use case at hand. For example, while a specific amount of generic blur or disruption in the smoothness of the continuous horizontal and/or vertical parallax may cause minor inconveniences in a given use case, it may result in significant errors and substantial issues in another. In this paper, we analyze the use-case-specific quality degradations of light field visualization. Each and every key performance indicator of light field visualization quality is addressed, and their effects are separately studied in the context of each use case. Display and content parameters, such as angular resolution, are examined on the level of individual and combined thresholds. The investigated use cases cover industrial, medical, commercial, educational, cultural and communicational scenarios. Therefore, both active and passive utilizations are considered, and a special emphasis on task performance is included in this paper.
