How hard is it to accommodate them? There are some additional challenges that you may encounter when conducting testing with people with disabilities; however, these challenges should not be considered overwhelming.\u003c/p\u003e\n\u003cp\u003eI spoke with Peter McNally, a Senior Usability Consultant at the \u003ca href=\"http://www.bentley.edu/centers/user-experience-center\"\u003eUser Experience Center at Bentley University\u003c/a\u003e, to get his take on usability testing with users who have visual impairment.\u003c/p\u003e\n\u003ch2 id=\"why-does-testing-matter\"\u003eWhy does testing matter?\u003c/h2\u003e\n\u003cp\u003ePerceptions exist that users with disabilities are a very small user population and not the primary set of users. In a consulting setting, your client may not feel that visually impaired users represent true users. However, looking at any recent demographic figures should counter this perception: according to the \u003ca href=\"https://nfb.org//\"\u003eNational Federation of the Blind\u003c/a\u003e, there are over 6 million people with a vision impairment in the United States (\u003ca href=\"https://nfb.org/blindness-statistics\"\u003estatistics as of 2012\u003c/a\u003e).\u003c/p\u003e\n\u003ch2 id=\"how-can-i-find-users-for-testing\"\u003eHow can I find users for testing?\u003c/h2\u003e\n\u003cp\u003eIf you typically use a recruiting firm to get usability testing participants, ask if they have any experience with recruiting people with disabilities. Also, reach out to local disability advocacy groups as they may have a pool of willing participants that want to help out and get their voices heard.\u003c/p\u003e\n\u003ch2 id=\"how-can-i-prepare-for-participants-that-use-assistive-technology-at\"\u003eHow can I prepare for participants that use assistive technology (AT)?\u003c/h2\u003e\n\u003cp\u003eVisually impaired users typically customize software such as screen readers or screen magnifiers. As part of the recruiting process, ask what AT and version they use. If possible, ask them to bring their equipment to the usability testing if you are testing at your location. However, there may be compatibility issues with the usability testing equipment and software. Another option is to go to their workplace or home so you can see their set up. Lastly, contact your local \u003ca href=\"http://www.easterseals.com/\"\u003eEaster Seals\u003c/a\u003e chapter as you may be able to borrow AT for your testing.\u003c/p\u003e\n\u003ch2 id=\"what-are-some-logistical-challenges-to-be-aware-of\"\u003eWhat are some logistical challenges to be aware of?\u003c/h2\u003e\n\u003cp\u003eWhen having users with disabilities come to your location for usability testing, there are some challenges to be aware of. First, make sure you confirm the transportation details with the participant. Will they be getting public transportation, using their own transportation, or relying on a taxi? It is best to have them call you from their cell phone and meet them outside your office when they arrive. If they are taking a taxi, you might offer to pay for the trip, if this is in your budget, or increase the compensation to cover the additional costs.\u003c/p\u003e\n\u003cp\u003eOnce you greet them, you will need to bring them to your testing location. Ask the participants if they would like to be guided. They may not, but it is good to ask. The NCBI Group offers \u003ca href=\"http://www.ncbi.ie/information-for/friends-and-relatives/guiding-a-person-with-a-vision-impairment\"\u003esuggestions on how to guide a person with a visual impairment\u003c/a\u003e.\u003c/p\u003e\n\u003cp\u003eMake sure the building you will be testing in is accessible. Review the most accessible route beforehand. Locate the elevators if necessary and review all fire drill procedures in case you need to evacuate the building during testing.\u003c/p\u003e\n\u003cp\u003eThe actual test process should be very similar to testing with the general population, e.g., think-aloud protocol. However, it is probably best to schedule 25% more time than testing with the general population for extra-setup and logistics.\u003c/p\u003e\n\u003cp\u003eAlso, consider the following:\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003eIf the participant is using a screen reader, be sure not talk over the screen reader during the usability test.\u003c/li\u003e\n\u003cli\u003eIf the participant has a service animal, don’t treat the animal as a pet; they are on the clock.\u003c/li\u003e\n\u003cli\u003eWhen you moderate, in general, don’t worry about using the word “see” as in “did you see that on the web site?” You should not offend most people.\u003c/li\u003e\n\u003cli\u003eAn online version of the book, \u003ca href=\"http://www.uiaccess.com/accessucd/\"\u003eJust Ask: Integrating Accessibility Throughout Design\u003c/a\u003e, offers \u003ca href=\"http://www.uiaccess.com/accessucd/ut_conduct.html\"\u003eadditional information on incorporating accessibility into usability testing\u003c/a\u003e.\u003c/li\u003e\n\u003c/ul\u003e\n\u003ch2 id=\"do-you-have-any-final-suggestions\"\u003eDo you have any final suggestions?\u003c/h2\u003e\n\u003cp\u003eOverall, usability testing with people with disabilities should feel the same as usability testing with the general population. I recommend using the same tasks for all participants, regardless of disability, as the goals of the site or application should be the same for everyone. Also, I would test with a mixture of participants—some with disabilities and some without any known (or stated) disabilities—so you can show to your clients/sponsor that usability issues are usability issues, regardless of disabilities.\u003cem\u003eThis is the first post in a series about usability testing with people with disabilities. Check back for a second post that will provide additional testing tips.\u003c/em\u003e\n\u003cem\u003eStacey Sarris is a User Experience (UX) consultant and adjunct professor at Pace University, doctoral candidate at University of Baltimore’s Information and Interaction Design program, and was a UX intern at GSA.\u003c/em\u003e\u003c/p\u003e\n"}
