Abstract

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.
