The presentation discusses the importance of designing and testing for accessibility in web applications, emphasizing that it benefits all users and is often a legal requirement. It outlines ten principles of web accessibility and encourages inclusive design that accommodates a wide range of abilities. The document also highlights the significance of empathy and collaboration in accessibility testing, as well as providing resources for further exploration in the field.
![HUMBLE
Humanize:
Be empathetic, understand the emotional components.
Unlearn:
Step away from your default [device-specific] habits. Be able to switch into different
habit modes.
Model:
Use personas that help you see, hear and feel the issues. Consider behaviors, pace,
mental state and system state.](https://image.slidesharecdn.com/atdlarsen-allforwebaccessibility-180302000541/85/Making-a-Web-for-Everyone-12-320.jpg)
Making a Web for Everyone
- 1. AGILE TESTING DAYS 2015 – Potsdam, Germany MAKING A WEB FOR EVERYONE Designing and Testing for Accessibility Michael Larsen mkltesthead@gmail.com Twitter: @mkltesthead
- 2. Special Thanks to Albert Gareev for collaborating on this talk. https://twitter.com/agareev http://automation- beyond.com/about/
- 3. What Does Accessibility mean to you? Designed to allow as many people as possible to access information. Open to allow people with disabilities a similar experience as their normative counterparts
- 5. Why Focus on Accessibility? It's the right thing to do It’s the law in many places Accessible sites are more usable for everyone It’s good business
- 6. Disabilities Visual Auditory Mobility Cognitive Any or all of the above. Images from "A Web for Everyone", S. Horton and W. Quesenbery, Rosenfeld Media, 2013
- 7. Normative Disabilities Hearing – in a loud environment Cognitive – when stressed or distracted Visual – web on a mobile screen Language – ESL, or any 2nd language
- 8. Ten Principles of Web Accessibility 1. Avoid making assumptions about the the physical, mental, and sensory abilities of your users whenever possible. 2. Your users’ technologies are capable of sending and receiving text. That’s about all you’ll ever be able to assume. 3. Users’ time and technology belong to them, not to us. You should never take control of either without a really good reason. 4. Provide good text alternatives for any non-text content.
- 9. Ten Principles of Web Accessibility 5. Use widely available technologies to reach your audience. 6. Use clear language to communicate your message. 7. Make your sites usable, searchable, and navigable. 8. Design your content for semantic meaning and maintain separation between content and presentation.
- 10. Ten Principles of Web Accessibility 9. Progressively enhance your basic content by adding extra features. Allow it to degrade gracefully for users who can’t or don’t wish to use them. 10. As you encounter new web technologies, apply these same principles when making them accessible.
- 11. Accessibility Testing Heuristic Be “HUMBLE”
- 12. HUMBLE Humanize: Be empathetic, understand the emotional components. Unlearn: Step away from your default [device-specific] habits. Be able to switch into different habit modes. Model: Use personas that help you see, hear and feel the issues. Consider behaviors, pace, mental state and system state.
- 13. HUMBLE (cont.) Build: Knowledge, testing heuristics, core testing skills, testing infrastructure, credibility. Learn: What are the barriers? How do users Perceive, Understand and Operate? Experiment: Put yourself into literal situations. Collaborate with designers and programmers, provide feedback
- 14. There’s a bug here. Can you see it? What if you “heard” it?
- 15. Inclusive Design Two “arguable” definitions: Accessibility “The design of products, devices, services, or environments for people with disabilities. The concept of accessible design ensures both "direct access" (i.e. unassisted) and "indirect access" meaning compatibility with a person's assistive technology.” (from Wikipedia, see https://en.wikipedia.org/wiki/Accessibility) Inclusive Design ‘The design of mainstream products and/or services that are accessible to, and usable by, as many people as reasonably possible ... without the need for special adaptation or specialized design.’ (British Standards Institute (2005), see http://www.inclusivedesigntoolkit.com/betterdesign2/whatis/whatis.html#p3 0)
- 16. Why Inclusive Design? Populations are living longer, and striving to keep doing the things that matter to them. People are not “able bodied” or “disabled”. There is a continuum, and all of us sit on and move along that continuum as we age. Minimizing capability demands allows more people to use the product. Greater population able to use product directly improves overall user experience.
- 17. Personal Example: LoseIt App to track calorie consumption, exercise output and weight loss. Data intensive app, lots of values to display and calculate Covers a range of targets and goals: • Calories consumed • Macronutrient breakdown • Steps taken • Challenges accepted
- 22. Recap Make it highly structured - easier to learn, remember, navigate, and operate Make it consistent in terms of design, implementation, and communication - for the same benefits as above, and product maintenance will be easier Provide more than one way in function and navigation Test your implementation!
