Subtitles in 360-degree Video

Currently there exists no agreed-upon user experience guidelines regarding subtitling (closed captions) in immersive 360-degree video experiences. It is not clear how subtitles might be acceptably displayed within this context, namely to support the balance between comprehension, freedom to look around the scene, and immersion. This work-in-progress describes four subtitle behaviours that we have designed and implemented in order to perform user-testing. We describe our rationale for each behaviour and discuss our initial hypotheses surrounding a full empirical investigation.
