Evaluation of Human Behavior Difference with Restricted Field of View in Real and VR Environments
Yoshiaki Mizuchi, Tetsunari Inamura · 2018
Motion capturing and analysis is gaining attention as a way to achieve intelligent systems that support human daily-life activities. Utilizing immersive VR systems is one way to facilitate the observation and accumulation of human behavior. Although recent improvements in 3D head-mounted displays and hand tracking controllers enable us to cheaply capture natural human behavior in various scenarios, there is concern about the inconsistency of human behavior between a real physical environment and a VR one. The restriction of the field of view (FOV) is a major factor in such inconsistency, such as underestimation of distance. The effect of FOV restriction on human behavior in complex scenarios (e.g., daily-life activities requiring recognition speed and manipulation skill) in the VR environment is still unclear. In this work, we investigate whether there is any consistency of human behavior concerning recognition speed and object manipulation skill depending on the FOV restriction in both real and VR environments. We designed and carried out an object manipulation task, to perform this investigation.
