Why just 3 things?

Adding a long list of things to check or to think about when considering accessibility will decrease the likeliness that you will focus on this stuff when you do real d.

3 things are more easy to remember with the acronym CVC or Complexity, Vision and Color.

Problem: Do you really need your user to enter all these fields?

Isn’t it possible to use new technologies like GPS location with a nice button to make the user faster to get localized?

SOLUTION: A single field for all or better more fields with fewer things to enter or to focus on reducing mental fatigue.
