Robyn:

I completely agree that tools are never a substitute for real users (I was
compelled to write a blog post about this just last week). However, when
I'm in an internal meeting where decisions are being made that may put a
low vision user's optimal experience at risk, tools that are readily
available on my iPhone allow me to demonstrate what we're really discussing
in that moment. They provide an on-demand empathy that puts the user back
at the center of the discussion.

One day, my team will have low vision users on staff who can provide that
first-hand experience. One day, our usability testing with disabled users
will reinforce universal design principles with stakeholders. Until then,
however, these kinds of tools help provide a more concrete example than I
could with just my words.



Best,
Elle
