Motion capturing and analysis is gaining attention to realizing intelligent systems that support human daily-life activities. Utilizing immersive VR systems is a solution to reduce costs of developing experiment environments. Although recent improvements in 3D head-mounted displays and hand tracking controllers enable us to capture natural human behavior in various scenarios easily, there is concern about the inconsistency of human behavior between a real physical environment and a simulated VR one. In particular, the restriction of the field of view (FOV) is known as a major factor in causing the inconsistency such as underestimation of distance. However, the influence of FOV restriction on daily-life activities concerning spatial perception and object manipulation in the VR environment is still unclear. In this paper, we evaluate the difference in human behavior depending on the FOV restriction in the real and VR environments from comparison results of completion time of an object manipulation task.
