Beyond Audio Description: Exploring 360° Video Accessibility with Blind and Low Vision Users Through Collaborative Creation.

While audio description (AD) is a standard method for making traditional videos more accessible to blind and low vision (BLV) users, we lack an understanding of how to make 360° videos accessible while preserving their immersive nature. Through individual interviews and collaborative design workshops, we explored ways to improve 360° video accessibility with immersion and engagement in mind. Our design workshops presented a unique opportunity for participants with diverse backgrounds to build on each others' personal and professional experiences and collaboratively develop accessible 360° video prototypes. Participants included both AD creators and users, with a focus on BLV AD creators as their perspectives are underrepresented in prior work. We found that immersive video accessibility went beyond an extension of traditional video accessibility techniques. Participants valued accurate vocabulary and different points of view for descriptions, preferred a variety of presentation locations for spatialized AD, appreciated sound effects for setting the mood and subtly guiding, and wished to engage multiple senses to boost engagement. We conclude with implications for immersive media accessibility and future research directions to support disabled people as creators of access technology. [ABSTRACT FROM AUTHOR]
