Abstract:	Accessibility in immersive media is a relevant research topic, still in its infancy. This article explores the appropriateness of two rendering modes (fixed-positioned and always-visible) and two guiding methods (arrows and auto-positioning) for subtitles in 360º video. All considered conditions have been implemented and integrated in an end-to-end platform (from production to consumption) for their validation and evaluation. A pilot study with end-users has been prepared and conducted with the goals of determining the preferred options by users, the options that results in a higher presence, and of gathering extra valuable feedback from end-users. The obtained results reflect that, for the considered 360º content types, always-visible subtitles are more preferred by viewers and received better results in the presence questionnaire than the fixed-positioned subtitles. Regarding guiding methods, participants preferred arrows over auto-positioning, because arrows were considered more intuitive and easy to follow and reported better results in the presence questionnaire.
