Re: Accessibility user testing

Some people have mentioned running remote sessions using screen sharing. I'm not at all keen on that. I like to see what keystrokes participants are using and what they are doing with the mouse. I also like to see their expression and body language - it tells you so much more than their words alone. Because of this, we used to do all our user testing in people's homes although we now do quite a lot in our in-house UX lab.

Whilst I agree that the focus should generally be on whether people are successful in completing the scenarios you give them, bear in mind that it only shows that the scenario *can* be completed successfully. It does not mean that all users with the identical disability *will* be able to complete it. So much depends on their preferred strategies for navigating websites and individual pages. Many times I have seen people complete tasks on websites that we considered to have poor accessibility, just because the accessible parts of the website matched their preferred strategies.

For this reason I recommend supplementing user testing with an expert review with assistive technologies that methodically goes through all the content. Neither is a complete solution but together they are about as good as you can get (assuming you have already done WCAG compliance testing to achieve a good level of technical accessibility).

Subject: Re: [WebAIM] Accessibility user testing

Just one more thought. If you are not familiar with screen reading, you might want to try and find an expert screen reader user, even an accessibility person, in your area and do a pilot test with that person face to face.
I think it may help you set expectations and get a little bit of a feel for the task.
You can be successful without it, but I often find that, as a screen reader user, sitting down with usability testers and going through the tasks informally helps them feel more comfortable.
Cheers
