“…Likewise, the presentation of Easy-to-Read subtitles is supported. Results from conducted tests have preliminarily proven that Easy-to-Read subtitles are preferred over tradditional subtitles by elderly participants when watching VR360 clips from an opera performance [48]. That recent study has also confirmed the positive attitude of the elderly towards the consumption of VR360 content for enjoying culture and arts.…”

The use of Virtual Reality (VR) technologies and, in particular of VR360 content, can provide great benefits in the society. This particularly applies to the culture and heritage sectors, where venues, goods and events can be digitalized to provide hyper-realistic and engaging experiences, anywhere and anytime. Despite significant advances in the field of VR, there is still an unexplored aspect which is crucial for every service and experience where user interaction is expected: accessibility. This article firstly reviews the needs, challenges and limitations for making VR360 experiences accessible. Based on these facts, an end-to-end platform to efficiently integrate accessibility services within VR360 content is presented. The platform encompasses all steps from media authoring to media consumption, but special attention is given to the accessibility-enabled VR360 player, as it is the end user interaction interface. The presentation modes for the supported access services (like subtitling, audio description and sign language), interaction modalities and personalization features supported by the player are described. To conclude, the availability of newly created and adapted culture-related accessible VR360 content is explored, as a proof of the potential of the contributions work in this sector.

“…Given the lessons learned and still open questions, future work will be targeted at:  Exploring the adoption and benefits of hybrid and advanced presentation modes and strategies, based on the dynamic user's and speaker's positions and viewpoints, as well as on the presented VR scenes.  Exploring the adoption and benefits of Easy-to-Read subtitles [33] in 3D VR scenes and environments, due to identified difficulties in following the subtitles for specific (fast and high-motion) scenes. …”

Subtitling 3D VR Content with Limited 6DoF: Presentation Modes and Guiding Methods

Every (multimedia) service needs to be accessible. Accessibility for multimedia content is typically provided by means of access services, of which subtitling is likely the most widespread one. Up to date, many recommendations and solutions for subtitling classical 2D audiovisual services are available. Likewise, recent efforts have been devoted to devising adequate subtitling solutions for VR360 video content. This paper, for the first time, goes a step beyond, by exploring two key requirements to fulfill remaining challenges towards efficiently subtitling 3D Virtual Reality (VR) content: presentation modes, and guiding methods. By leveraging insights from earlier work on VR360 content, the paper proposes novel presentation modes and guiding methods to not only deal with the freedom to explore the omnidirectional scenes, but also with additional specificities of 3D VR compared to VR360 content: depth, 6 Degrees of Freedom (6DoF), and viewing perspectives. The obtained results prove that always-visible and a novel proposed comic-style presentation mode are far more appropriate than state-of-the-art fixed-positioned subtitles, mainly in terms of immersion, ease and comfort of reading, and identification of speakers, when applied to professional pieces of content with limited displacement of speakers and with limited 6DoF (i.e. users are not expected to largely navigate around the virtual environment). Likewise, even in such limited movement scenarios, the results show that the use of indicators (arrows), as guiding methods, is well received. Overall, the paper provides relevant insights and paves the way toward efficiently subtitling 3D VR content.

“…Likewise, the player has been built by making use of HTML5 and JavaScript, and by adopting widespread web components and APIs, such as: dash.js 28 (the reference player for DASH), three.js, 29 WebXR, 30 and IMSC rendering libraries. 31 In addition, the player includes the necessary technological solutions to enable multi-screen scenarios in a synchronized and interactive manner, in both fully web-based and Hybrid Broadcast Broadband TV (HbbTV) [15] scenarios, as described in [24].…”

Accessibility is a key requirement for any multimedia tool and application. With the current trend towards immersive experiences, such as Virtual Reality (VR) and 360o 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 360o 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° 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° 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° video.
