Re: Parallax and vestibular disorders

Hi Alastair,

Asking a person with first-hand experience can't hurt to inform the issue.

It seems like Nat (Gregory) Tarnoff is now working for SSB BART Group
[1]. I think we have a few working group members who also work there
such as Jon Avila. Maybe that may be a way to reach out. But the
Chairs may know the best approach.

Kindest Regards,
Laura
