„For people who do not experience barriers, it can be difficult to empathize with the challenges that people with disabilities often face when navigating the Web. The Accessibility Maze was created to help those new to web accessibility experience firsthand what it is like to encounter those barriers. The game introduces a number of common barriers players must work around, mirroring the experience of those who encounter these obstacles daily, and provides quick lessons on how to avoid or correct them.“
