  Any media experience must be fully inclusive and accessible to all users
regardless of their ability. With the current trend towards immersive
experiences, such as Virtual Reality (VR) and 360-degree video, it becomes key
that these environments are adapted to be fully accessible. However, until
recently the focus has been mostly on adapting the existing techniques to fit
immersive displays, rather than considering new approaches for accessibility
designed specifically for these increasingly relevant media experiences. This
paper surveys a wide range of 360-degree video players and examines the
features they include for dealing with accessibility, such as Subtitles, Audio
Description, Sign Language, User Interfaces, and other interaction features,
like voice control and support for multi-screen scenarios. These features have
been chosen based on guidelines from standardization contributions, like in the
World Wide Web Consortium (W3C) and the International Communication Union
(ITU), and from research contributions for making 360-degree video consumption
experiences accessible. The in-depth analysis has been part of a research
effort towards the development of a fully inclusive and accessible 360-degree
video player. The paper concludes by discussing how the newly developed player
has gone above and beyond the existing solutions and guidelines, by providing
accessibility features that meet the expectations for a widely used immersive
medium, like 360-degree video.
