Eye-tracked Evaluation of Subtitles in Immersive VR $360^{\circ}$ Video

The paper presents an analysis of visual attention to subtitles within immersive media. We implement a
$360^{\circ}$
video rendering with eye movements recorded in Virtual Reality. Position and color of im-mersive subtitles are compared in terms of perceived task load and cognitive processing of the content. Results show that head-locked subtitles afford more focal visual inspection of the scene and pre-sumably better comprehension. This type of in-depth analysis would not be possible without the eye movement analyses.
