Summary
Did you know that the SUS creates biases in your research, affecting one in five people? That’s right! People with disabilities, especially those who use assistive technology, are not considered by most of the questions in the SUS. As a designer, this could lead to you making design decisions that don’t take into account 20 percent of the visitors to your website. When the SUS was invented, the author encouraged people to change it to suit different needs. In this talk, Samuel Proulx from Fable will discuss how Fable adapted the SUS to work for assistive technology users. Drawing from over five thousand hours of research and testing involving assistive technology users, we created the Accessible Usability Scale (AUS). This presentation will include trends in AUS responses since it was released in December of 2020.
