Usability testing involving people with disabilities – What's the process?

The InterAccess usability testing process, is backed by many years of usability experience working directly with people with disabilities. Our main goals are to provide an environment for our panel to comfortably test your website, app or service in a way that can give the best results.

The remote dynamic means that these tests may be directly or indirectly facilitated. This depends on the members of the panel’s personal circumstances and situation.

The test process steps are outlined broadly as follows (with some more detail below):

  • Recruitment of usability test participants
  • Test script design containing representative tasks and goals
  • An experienced usability test facilitator will introduce the test participant to the service to be tested, and ask the test participant to follow a set of representative flows or tasks
  • Video recording of the user performing the test (where possible)
  • Post test questions are asked to assess the experience

A usability test report is compiled (with video highlights and recommendations), and provided to the client and any actionable outcomes are discussed.

InterAccess Usability Testing Panel

Our panel of usability testers are people with a range of disabilities who use assistive technologies. These are screen reader, screen magnifier, keyboard only, switch or voice access technologies. Some may use combinations of technologies, or have accessibility related needs where they do not use assistive technology at all. All our test participants all have varying levels of AT proficiency from beginner to power users.

InterAccess remote usability testing – the protocol

In a usability test, each user carries out a set of realistic tasks that have been agreed beforehand with our client. These will usually include the most common tasks for which the product is used, as well as the most critical tasks and any tasks that test facilitator feels will cause problems. Tests are carefully designed to yield the most realistic user behaviour and best results.

InterAccess mainly use a think aloud protocol.
