Analysis of the Relationship Between Content and Interaction in the Usability Design of 360o Videos

In the recent years, 360° images and video became a popular format for designing, producing, and consuming information. Immersive videos enable users to control the viewing angle at playback, and experience content in a unique fashion. Therefore, understanding how viewers interact with 360° video is crucial for improving their design, production, distribution, and consumption. In this paper, we introduce a model for categorizing 360° video based on the type of points of interest in the scene, and we present a study in which we analyzed heatmaps and changes in the viewing angle to identify the key features of regions of interest, the common interaction patterns within video categories, and the relationship between content design and engagement.
