[x3d-public] Web3DUX working group minutes 8 April 2020

Wow - you've done some great things Nicholas, so interesting.
-Doug

Q. what's missing from VR - what's holding it back from solving all the
world's problems?
H: weak on outputs:
- great for input devices and building a virtual world and entering the
virtual world and perhaps even solving problems in the virtual world.
x but weak on getting the virtual world results back out to do work in the
real world
If so then perhaps this is the next things to work on.
And I can think of a few problems:
1) the real world has a way of updating itself, so keeping virtual world
version synced is one challenge
2) output devices - robot arms tend to be expensive, and the more power
they have, the more dangerous they are, so safety precautions
I can think of some nodes for #1, but not used to thinking about #2, I draw
a blank
