Summary: Designing for VR must include users with disabilities. If you are working on AR or VR content, the accessibility of your app or piece should be on your radar from design time through to implementation.
Designing for blind users in VR requires the use of spatial audio using tested 3D sound techniques. At Experience Dynamics we work on a lot of R&D projects that we end up publishing results to the wider UX/ HCI community. One of these projects is a Disability & VR project called SoundSpace.
We include this case study/ demo (VIDEO) included below of how sound can aid navigation, information finding and social VR.
