Persona gap analysis

Kevin White edited this page Nov 11, 2020 · 3 revisions

Purpose of How people with disabilities use the web

The original purpose was to raise awareness of the different approaches to access the web that people have. There is still a need for that but there is the opportunity to present needs and barriers within each persona to help design teams explore how solution options do or don't support disabled people.
