This text focuses on the customers of display screen readers — particular software program that converts the supply code of a web site or app into speech. Often, these are folks with low imaginative and prescient and blindness however not solely. They’ll enable you to uncover most accessibility points. After all, the subject is simply too huge for a single article, however this would possibly assist to get began.

Half 1. What Is Accessibility Testing?
1.1. Testing vs. Audit
There are various methods of evaluating the accessibility of a digital product, however let’s begin with distinguishing two main approaches.
Auditing is an element-by-element comparability of a web site or app towards a listing of accessibility necessities, be it a common customary (WCAG) or a country-specific regulation (like ADA within the U.S. or AODA in Ontario, Canada). There are two methods to do an audit:
- Automated audit
Checking accessibility by the use of net apps, plugins for design and coding software program, or browser extensions (for instance, axe DevTools, ARC Toolkit, WAVE, Stark, and others). These instruments generate a report with points and proposals.
- Professional audit
Analysis of net accessibility by an expert who is aware of the necessities. This particular person can make use of assistive expertise and have a incapacity, however that is anyway an skilled with superior information, not a “widespread person.” Consequently, you get a report too, nevertheless it’s extra contextual and smart.
Testing, not like auditing, can’t be completed by one particular person. It entails customers of assistive applied sciences and includes a set of one-on-one classes facilitated by a designer, UX researcher, or one other skilled.
Right now we’ll deal with testing as an undervalued but highly effective methodology.
1.2. Usability vs. Accessibility Testing
You may need already heard about usability testing and even tried it. No surprise it’s the highest analysis methodology amongst designers. So how is it totally different from its accessibility counterpart?
In each instances, a facilitator prepares a full written script with an introduction, questions, and duties based mostly on a sensible situation (for instance, shopping for a ticket or ordering a taxi). By the best way, listed below are helpful testing script templates.
- Insights gathering
Regardless of accessibility testing’s primary focus, it additionally reveals a number of usability points, merely stated, whether or not a web site or app is straightforward to make use of. In each instances, a facilitator ought to ask follow-up inquiries to get an perception into folks’s mind-set, ache factors, and wishes.
Each testing sorts could be organized on-line or offline. Often, one session takes from half-hour to 1 hour.
- Members choice
Individuals for usability testing are recruited primarily by demographic traits: job title, gender, nation, skilled expertise, and so forth. While you check accessibility, you take note of the senses and assistive applied sciences concerned in utilizing a product.
- What you’ll be able to check
In usability testing, you’ll be able to check a dwell product, an interactive prototype (made in Figma, Protopie, Framer, and so forth.), or perhaps a static mockup. Accessibility testing, typically, requires a dwell product; prototyping instruments can not ship a supply code appropriate with assistive expertise. Figma attempted to make prototypes accessible, nevertheless it’s nonetheless removed from excellent.
- Giving hints
When individuals get caught within the move, you assist them discover the best way out. However if you contain folks with disabilities, it’s important to perceive how their assistive gear works. Simply to present you an instance, a phrase like “Click on on the crimson cross icon within the nook” will sound foolish to a blind person.
1.3. Why Choose For Testing?
Now that you already know the distinction between an audit and testing and the excellence between usability and accessibility testing, let’s make clear why testing is so highly effective. There are two causes:
- Get priceless insights.
The concept of testing is to be taught how one can enhance the product. Whilst you gained’t verify all interface parts and edge instances, such classes present if the entire move works and if folks can attain the objective. Not like even essentially the most complete audits, testing is far nearer to actuality and based mostly on the utilization of actual assistive expertise by an individual with a incapacity.
- Construct empathy by means of storytelling.
story is extra compelling than naked numbers. In addition to, it could possibly function a useful addition to such fashionable pro-accessibility arguments as authorized dangers, successful new clients, or model impression. Even 1–2 thorough classes can provide you adequate materials for a vivid story to excite the workforce about accessibility. An audit report alone might not be as thrilling to learn.
Testing offers you extra practical insights into widespread eventualities. Legal guidelines and requirements aren’t excellent, and formal compliance won’t cowl all of the person challenges. Typically folks take not the “designed” path to the objective however the one which appears safer or extra intuitive, and testing reveals it.
After all, auditing remains to be a robust methodology; nevertheless, its mixture with testing will present rather more correct outcomes. Now, let’s speak about accessibility testing intimately.
Half 2. Recruiting Customers
There are various sorts of disabilities and, consequently, numerous assistive applied sciences that assist folks browse the online. And not using a deep dive into concept, let’s simply recap the number of disabilities:
- Relying on the senses concerned or the affected space of life: visible (blindness, coloration deficiency, low imaginative and prescient), bodily (cerebral palsy, amputation, arthritis), cognitive (dyslexia, Down syndrome, autism), auditory (deafness, listening to loss), and so forth.
- By severity: everlasting (for instance, an amputated leg or some innate situation), short-term (a damaged arm or, let’s say, blurred imaginative and prescient proper after utilizing eye drops), and situational (as an illustration, a loud room or carrying a toddler).
Observe: You will discover extra data on numerous sorts of disabilities on the Microsoft Inclusive Design hub.
For the sake of simplicity, we’ll deal with the case relevant to most digital merchandise: when a web site or app principally depends on imaginative and prescient. On this case, visible assistive applied sciences supply customers another option to work with content material on-line. The most typical applied sciences are:
- Display readers: software program that converts textual content into speech and has quite a few helpful shortcuts to navigate effectively. (We’ll speak about it intimately within the subsequent chapters.)
- Refreshable Braille shows: units in a position to present a line of tactile Braile-script textual content. Spherical-tipped pins are raised by means of holes in a floor and refresh as a person strikes their cursor on the display screen. Such shows are important for blind-deaf folks.
- Digital assistants (Amazon Alexa, Apple Siri, Google Assistant, and others): a superb instance of common design that serves the wants of each folks with disabilities and non-disabled folks. Assistants interpret human speech and reply through synthesized voices.
- Excessive-contrast shows or particular modes: for folks with low imaginative and prescient. Some customers mix a high-contrast mode with a display screen reader.
2.1. Who To Contain
Debates round an optimum variety of testing individuals are unending. However we’re speaking right here a few specific case — organizing accessibility testing for the primary time, therefore the advice is the next:
- Invite 3–6 customers with blindness and low imaginative and prescient who both browse the online by the use of display screen readers or use a particular mode (for instance, additional zoom or elevated distinction).
- In case your product has wealthy knowledge visualization (charts, graphs, dashboards, or maps), contain a number of folks with coloration blindness.
In any case, it’s higher to conduct even one or two high-quality classes than a dozen of poorly ready ones.
2.2. The place To Discover Individuals
It isn’t as onerous to seek out folks for testing because it appears at first look. In case you are engaged on a mass product for 1000’s of customers, individuals gained’t want any particular information other than proficiency with their assistive expertise. Listed here are three sources we advocate checking:
- Specialised platforms for recruiting customers in keeping with your parameters (for instance, Access Works or UserTesting). This methodology is the quickest however not the most affordable one as a result of platforms take their fee on high of person compensation.
- Social media communities of individuals with disabilities. Strive looking by the key phrases like “folks with disabilities,” “PWD,” “assist group,” “visually impaired,” “partially sighted,” or “blind folks.” Ask the admin’s permission to publish your analysis announcement, and it gained’t be rejected.
- Social enterprises and non-profits that work within the space of inclusion, employment, and assist for folks with disabilities (for instance, Inclusive IT in Ukraine or The Federation of the Blind and Partially Sighted in Germany). Drop them an e-mail along with your request.
We observed that the final two factors would possibly sound like getting individuals at no cost, however not everybody has a chance to volunteer.
After we organized accessibility testing classes final yr, three individuals agreed to participate professional bono as a result of it was a college course, and we didn’t get any income. In any other case, be able to compensate for the participant’s time (in my expertise, round €15–30). It may be an Amazon reward card or coupon for one thing helpful in a selected nation (solely guarantee it’s accessible).
Digital product corporations that check accessibility often rent folks with disabilities in order that they’ve entry to in-progress software program and may verify it iteratively earlier than the official launch.
Half 3. Getting ready For The Session
Now that you just’ve recruited individuals, it’s time to debate issues to arrange earlier than the classes. And the primary query is:
3.1. On-line Or offline?
There are mainly two methods to conduct testing classes: remotely or face-to-face. Whereas we often favor the primary one, each methods have execs and cons, so let’s speak about them.
Advantages of on-line:
- Native surroundings.
Members can use acquainted residence tools, like a desktop pc or laptop computer, with properly tuned assistive expertise (plugins, modes, settings).
- Value and time effectivity.
No must reimburse bills for touring to your workplace. It is likely to be fairly expensive if a participant arrives with an accompanying particular person or wants particular accessible transport.
- Simpler recruitment.
It’s extra seemingly you’ll discover a participant that meets your standards all over the world as a substitute of looking in your metropolis (and once more, zero journey bills).
Advantages of offline:
- Testing merchandise in growth.
When you have a product that isn’t public but, individuals gained’t have the ability to simply set up it or open it in a browser. So, you’ll have to ask individuals to your workplace, however they need to most likely carry the transportable model of their assistive expertise (for instance, on a USB drive).
- Testing cellular apps.
If an individual brings a private telephone, you’ll see not solely the interplay along with your product but in addition how the machine is about up and what gestures and shortcuts an individual makes use of.
- Serving to inexperienced customers.
Utilizing assistive expertise is a talent, and chances are you’ll contain somebody who will not be but proficient with it. So, the offline setting is extra handy when individuals get caught and also you assist them discover the best way out.
As you’ll be able to see, on-line testing has extra common benefits, whereas the offline format quite fits area of interest instances.
3.2. Communication Instruments
When you resolve to check on-line, a logical query is what instrument to decide on for the session. Mainly, there are two choices:
Specialised testing instruments (as an illustration, UserTesting, Lookback, UserZoom, Hotjar, Useberry):
- Other than primary conferencing performance, they assist superior note-taking, computerized transcription, click on heatmaps, dashboards with testing outcomes, and different options.
- They’re fairly expensive. In addition to, trial variations could also be too restricted for even a single actual session.
- Members could get caught with an unfamiliar instrument that they’ve by no means used earlier than.
Standard video conferencing instruments (for instance, Google Meet, Zoom, Microsoft Groups, Skype, Webex):
- Assist all of the minimally required performance, comparable to video calls, screen-sharing, and name recording.
- They’re often free.
- There’s a excessive probability that individuals know methods to use them. (Observe: even on this case, folks should still expertise hassle launching screen-sharing).
Since we’re speaking about your first accessibility testing, it’s a lot safer and simpler to make the most of an outdated good video conferencing instrument, specifically the one which your individuals have expertise with. For instance, after we organized academic testing classes for the Ukrainian Catholic College, we used Skype, and on the HTW College in Berlin, we selected Zoom.
Whatever the instrument selection, be taught prematurely how screen-sharing works in it. You’ll seemingly want to clarify it to among the individuals utilizing appropriate (non-visual) language. Consequently, the intro to accessibility testing classes could take longer in comparison with usability testing.
As we discovered earlier than, accessibility testing requires a working piece of software program (let’s say, an alpha or beta model); it’s tougher to construct, nevertheless it opens huge analysis alternatives. As an alternative of asking a participant to think about one thing, you’ll be able to really observe them ordering a pizza, reserving a ticket, or filling in an internet kind.
Suggestions for accessibility testing duties aren’t a lot totally different from those in usability testing. Duties needs to be real-life and formulated in a approach folks naturally suppose. As an alternative of referring to an interface (what button an individual is meant to click on), you must describe a state of affairs that would occur in actuality.
Begin a session with a mini-interview to find out about individuals’ related experiences. For instance, if you will check an air journey service, ask folks in the event that they journey regularly and what their desired locations are. Primarily based on these particulars, customise the duties — reserving a ticket to the place of the participant’s selection, not a generic location urged by you.
Examples of practical, broad duties:
- Testing a shopper product: bicycle on-line retailer.
You need to purchase a present card to your colleague George who enjoys bikepacking. Select the cardboard worth, customise different preferences, and choose how George will obtain the reward. (This job implies that you just discovered about an actual George who likes biking throughout a mini-interview.)
- Testing an expert product: buyer assist instrument.
Your supervisor requested you to try a number of vital points that haven’t been answered for every week. Discover these tickets and learn how to react to them. (This job implies that you just invited a participant who labored as a buyer assist agent or in an identical position.)
Examples of main UI-based duties:
- Shopper product
“Open the primary menu and discover the ‘Different’ class. Select a €50 reward card. Within the ‘For whom’ enter subject enter ‘John Doe’… Choose ‘Visa/Mastercard’ as a paying methodology…”
- Skilled product
“Navigate to the dashboard. Select the ‘Final week’ choice within the ‘Standing’ filter and take a look at the checklist of tickets. Apply the filter ‘Kind by date’ and inform me what the top-most merchandise is…”
A testing session is 50% preparation and 50% human dialog. It’s not sufficient to present even a well-formulated job and silently wait.
An preliminary job reveals which of the methods to perform a job a participant will select as essentially the most intuitive one. When an individual will get caught, you can provide hints, however they shouldn’t sound like “click on XYZ button”; as a substitute, allow them to discover additional. One thing like the next:
— No worries. So, the search doesn’t give the anticipated outcome. What else are you able to do right here?
— Hmm, I don’t know. Possibly filtering it someway…
— OK, please strive that.
Your communication type impacts individuals’ mind-set and the extent of bias. Even an enormous article gained’t cowl all of the nitty-gritty, however listed below are a number of frequent errors.
Watch out for the next:
- Main duties: “Go to the ‘Dashboard’ part and discover the frequency chart” or “Scroll to the underside to see superior choices.”
Such hints completely break the session, and you’ll by no means understand how an individual would act in actuality.
- Promoting language: “Verify our buy in a single click on” or “Strive the ‘Good filtering’ characteristic.”
It makes folks really feel as in the event that they should reward your product, not share what they actually suppose.
- Humorous duties: “Create a profile for Johnny Money” or, for instance, “Request Christmas tree supply to Lapland.”
Jokes distract individuals and reduce session realism.
- IT terminology: “On the dashboard, discover toggle swap” or “Go to the block with dropdowns and radio buttons.”
It’s unhealthy for 2 causes: chances are you’ll confuse folks with phrases they don’t perceive; it may be an indication that you just give main duties and extreme UI hints.
Right here is really useful additional studying by Nielsen Norman Group:
Half 4. Session Facilitation
As agreed earlier than, your first accessibility testing session will most likely contain a blind particular person or an individual with low imaginative and prescient who makes use of a display screen reader to browse the online. So, let’s cowl the 2 primary points it’s important to know earlier than beginning a session.
4.1. Display Readers
A display screen reader is an assistive software program that transforms visible data (textual content and pictures) into speech. When a visually impaired particular person navigates by means of a web site or app utilizing a keyboard or touchscreen, the software program “reads” the textual content and different parts out loud.
Display readers depend on the supply code however interpret it in a particular approach. They skip code accountable for visible results (like colours or fonts) and take note of significant elements, comparable to heading tags, textual content descriptions for footage, and labels of interactive parts (whether or not it’s a button, enter subject, or checkbox). The higher a code is written, the better will probably be for customers to grasp the content material.
Now that you understand how display screen readers perform, it’s time to expertise them firsthand. Relying on the working system, you’ll have a regular embedded display screen reader already out there in your machine:
- VoiceOver: Mac and iOS;
- Narrator: Home windows;
- TalkBack: Android.
Throughout one in every of our coaching programs, we discovered from blind customers that the display screen reader on iPhone is extra comfy and versatile than the Android one. Curiously, folks don’t like customary desktop display screen readers both on Mac or on Home windows and often set up one of many superior third-party readers, as an illustration:
- JAWS (Job Entry With Speech): Home windows, paid, the most well-liked display screen reader worldwide;
- NVDA (Non-Visible Desktop Entry): Home windows, freed from cost.
Visually impaired folks often navigate apps and websites utilizing a keyboard or touchscreen. And whereas sighted folks scan a web page and leap from one half to a different, display screen reader customers can maintain just one factor in focus at a time, be it a paragraph of textual content or, let’s say, an enter subject.
Members of your accessibility testing will seemingly run into an unpassable impediment in some unspecified time in the future within the session, and also you’ll give them hints on methods to discover the best way out and proceed with the subsequent job. On this case, you’ll want a particular non-visual language that is sensible.
Not useful hints:
- “Click on the cross icon within the higher proper nook.”
- “Scroll to the underside of the modal window and discover the button there.”
- “Have a look at the desk within the heart of the web page.”
- “Please, navigate to the subsequent/earlier merchandise.”
- “Go to the second factor within the checklist.”
- “Choose the final heading/hyperlink/button.”
Observe: UI hints above are urged for instances when a person is totally caught within the move and can’t proceed, for instance, when a component will not be navigable through a keyboard or, let’s say, an interactive factor doesn’t have a correct label or title.
As soon as all of the testing classes have been accomplished, you’ll be able to analyze the collected suggestions, decide priorities, and develop an motion plan. This course of could possibly be the topic of a separate guideline, however let’s cowl the three key rules immediately:
- Catching data
Testing produces tons of knowledge, so you ought to be ready to seize it; in any other case, will probably be misplaced or obscured by your imperfect human reminiscence. Don’t depend on a recording. Make notes within the course of or ask an assistant to try this. Notes are simpler to research and discover repeating observations throughout classes. In addition to, they make sure you’ll have knowledge if the recording fails.
- Uncooked knowledge ≠ insights
Not every little thing you observe in testing classes needs to be perceived as a name to motion. Uncooked knowledge exhibits what occurred, whereas insights clarify causes, motivations, and methods of considering. For instance, you see that individuals use search as a substitute of filters, however the perception could also be that typing a search request wants much less effort than going by means of the filter menu.
- Criticality and impression
Not all observations are vital. If 5 customers wrestle to proceed as a result of the procuring cart isn’t keyboard-navigable, it’s a significant barrier each for them and the enterprise. But when one out of 5 individuals didn’t just like the button title, it isn’t vital. Have in mind the next:
- What number of individuals encountered an issue;
- How a lot an issue impacts reaching the objective: reserving a ticket, ordering pizza, or sending a doc.
As soon as the knowledge has been collected and processed, it’s important to share it with the workforce: designers, engineers, product managers, high quality assurance people, and so forth. The extra interactive will probably be, the higher. Let folks take part within the dialogue, ask questions, and see what it means for his or her space of accountability.
As you achieve extra expertise in conducting testing classes, invite workforce members to watch the dwell stream (as an illustration, through Google Meet) or broadcast the session to a gathering room with observers, however make certain they keep silent and don’t intrude.
