[Sw-l] [x3d-public] X3D4 Working Group agenda, 20 OCT 2022: discuss possible Avatar strategy

Thu Oct 20 19:36:28 UTC 2022

I suggest we create a mapping between X3D/BVH, DanceWriting/MovementWriting
and especially SignWriting, with DanceWriting/MovementWriting and
SignWriting carrying the semantics, and X3D/BVH carrying the
physics/mathematics.

https://en.m.wikipedia.org/wiki/SignWriting

https://en.m.wikipedia.org/wiki/International_Movement_Writing_Alphabet

I believe there are current developments on this, as  reported on SW-L.

I believe that this, and translation to and/or supplementing with
Protactile for the deafblind will go a long way towards making the
Metaverse more accessible.

Note that Protactile is a full-duplex, two-way language, so that
full-duplex communication is critical to success.

Plain ol’ video generation isn’t going to solve this!
