To provide information for 360-degree visual space exploration, we design experiments to measure and analyze object-centric visual preference. After defining the static and dynamic properties of the objects of interest, we collect real-shot 360-degree videos and synthesize computer-generated 360-degree videos so that the objects have different combinations of static and dynamic properties. From head movement trajectories of subjects wearing head-mounted displays and watching 360-degree videos,

The experimental results indicate that subjects have visual preference for certain static and dynamic properties of objects over others; with this knowledge we can construct visually salient viewports by detecting and comparing static and dynamic properties of objects in a 360-degree video.
