Abstract

Omnidirectional video can be comprised of several scenes joined together. A scene in a video can change within the same semantic content due to switching to a different camera position (e.g., in a multi-camera sport event), referred to as intra-scene transition; in other situations, a scene in a video can change between different semantic content, referred to as inter-scene transition (e.g., a scene cut from a movie). — In this paper an attempt is made to 1) find the user exploration behavior in terms of the exploration range, angular speed and acceleration metrics; 2) Investigate whether there is any exploration behavioral change in the watching patterns between intra- and inter-scene transitions. — We find that there is an increase in the exploratory behavior for all the above-mentioned metrics, and show that there is a delay (reaction time) between the scene transition and the start of the exploration. Finally, we also show that the exploratory behavior is higher in inter-scene transitions compared to intra-scene transitions.
