The key performance indicators of projection-based light field visualization

Abstract

At the time of writing this paper, light field visualization has entered the professional environments in the industry and has also become commercially available. It is not yet present on the consumer market, however, and its widespread emergence is expected in the following decade, with affordable end user devices and a vast variety of applications and contents. The successful integration of this technology into people’s everyday lives essentially depends on the visualization quality, which is achieved through excellence in terms of the key performance indicators of the display system and the content it visualizes. In this paper, the key performance indicators of light field visualization for both display and content are reviewed. Beyond providing a comprehensive review of the vital parameters of visualization quality, this paper discusses the ongoing and future relevant research efforts, demonstrates the practical uses of the technology, highlights certain dependencies between the indicators, and addresses issues of perceived quality with regard to the lack of compliance with the requirements and visual thresholds.
