Overview of Measurement Methods for Factors Affecting the Human Visual System in 3D Displays

Three-dimensional (3D) display systems are widely used nowadays, and their psychophysiological effects on human health have been investigated in detail. However, due to recent advances in 3D display technology, such as (super) multiview display or holography, there is a clear and pressing need to develop a new measurement method for determining optimal viewing parameters. Depending on the display system in question, virtual objects with depth information may present different properties to the human visual system and thus are perceived differently. The methods to measure the factors that affect human health in 3D displays need to be thoroughly reviewed in order to further investigate these characteristics and determine optimal viewing parameters. In this paper, we review various measurement methods that have been proposed to examine the effects of 3D stimuli on the human visual system. We provide an overview of recent advances in 3D techniques by relating them with human factors, primarily focusing on subjective and objective measurement methods, to ensure that human-friendly 3D content and displays will benefit from recent technical advances.
