[Blindmath] Decline of Spatial Math in Braille?

[Aaron Cannon]

Hi all.

I'm curious to hear about how people are using Braille math these
days, either UEB or Nemeth.  Is it common for folks to work on
electronic devices with Braille displays?  If so, does the way in
which you use Braille math differ from how you would use it if, for
example, you were working on a Perkins Brailler?

Thanks.

Aaron
