  • Lower-Literacy Users: Writing for a Broad Consumer Audience

    Lower-literacy users exhibit very different reading behaviors than higher-literacy users: they plow text rather than scan it, and they miss page elements due to a narrower field of view.

  • Alternative Interfaces for Accessibility

    The key difference between user interfaces for sighted users and blind users is not that between graphics and text; it's the difference between 2-D and 1-D. Optimal usability for users with disabilities requires new approaches and new user interfaces.

  • Making Flash Usable for Users With Disabilities

    Flash designs are easier for users with disabilities to use when designers combine visual and textual presentations, minimize incessant movement, decrease spacing between related objects, and simplify features.

  • Beyond Accessibility: Treating Users with Disabilities as People

    With current Web design practices, users without disabilities experience three times higher usability than users who are blind or have low vision. Usability guidelines can substantially improve the matter by making websites and intranets support task performance for users with disabilities.

  • Disabled Accessibility: The Pragmatic Approach

    New official standards make it easy to get the top priorities right and make websites accessible for users with disabilities (e.g., blind users who can't see images). But the single-design approach may be nearing the end of its life.

  • Accessible Design for Users With Disabilities

    How to design websites for universal access, including users with visual, auditory, motor, and cognitive disabilities. Using good ALT-text only gets you so far.

  • Alternatives to Low-Contrast Text

    If the foreground color (the actual words) is too similar to the background color, legibility suffers, and users can't read your copy. Simple tweaks make websites much easier to read.

  • Convincing Companies to Do UX and Accessibility

    The relationship between accessibility and usability and the best ways to convince companies to take both seriously were some of the audience questions answered by Jakob Nielsen at the Virtual UX Conference.

  • 4 Things to Do When Designing for Seniors

    The number of senior citizens who use computers and the Internet grows every year. This user population does have special needs, driven by the human aging process, and modest design changes can vastly increase the business you get from seniors.

  • Changes in How Senior Citizens Use Computers

    Our new user research with seniors (users aged 65 and up) shows 3 major shifts in how they use computers, compared with our first research with this audience, 20 years ago. Design for today's older users, and not for your stereotype of how these users used to be.

  • Inclusive Design Is a Welcome Mat

    Inclusive design is a philosophy that redefines what it means to be human-centered. To design inclusively, designers need to respect and represent many different perspectives.

  • Vote By Mail: Mistakes Are Too Easy

    The design of vote-by-mail materials (made imperative by the COVID-19 pandemic) have UX issues that make the voting process unnecessarily difficult and error prone.

  • Executing UX Animations: Duration and Motion Characteristics

    Define a trigger, transformations, duration, and easing of the animation, and be mindful of accessibility issues and annoying the user.

  • Dark Mode vs. Light Mode: Which Is Better?

    In people with normal vision (or corrected-to-normal vision), visual performance tends to be better with light mode, whereas some people with cataract and related disorders may perform better with dark mode. On the flip side, long-term reading in light mode may be associated with myopia.

  • Treemaps: Data Visualization of Complex Hierarchies

    A treemap is a complex, area-based data visualization for hierarchical data that can be hard to interpret precisely. In many cases, simpler visualizations such as bar charts are preferable.

  • Usability for Seniors: Challenges and Changes

    Users ages 65 and older face unique challenges when using websites and apps. Digital literacy among this demographic is rising, but designs need to accommodate aging users.

  • Ensure High Contrast for Text Over Images

    If you place text over a background image, make sure it’s readable by providing adequate contrast. Subtle tweaks can increase the contrast without affecting the overall aesthetic of the site.

  • Screen Readers on Touchscreen Devices

    People who are blind or have low vision must rely on their memory and on a rich vocabulary of gestures to interact with touchscreen phones and tablets. Designers should strive to minimize the cognitive load for users of screen readers.

  • Low-Contrast Text Is Not the Answer

    Low-contrast text may be trendy, but it is also illegible, undiscoverable, and inaccessible. Instead, consider more usable alternatives.

  • Video Usability

    Video content is helpful only if users have control over it, understand what’s contained within it, and have an alternate way to access it.

  • Placeholders in Form Fields Are Harmful

    Labels or sample text inside a form field makes it difficult for people to remember what information belongs in that field once they start data entry.

  • Keyboard-Only Navigation for Improved Accessibility

    For users who can’t use a mouse make interactive and navigation elements easily accessible by tabbing and display a keyboard-focus indicator.

  • Usability for Senior Citizens: Improved, But Still Lacking

    Users aged 65 and older are 43% slower at using websites than users aged 21–55. This is an improvement over previous studies, but designs must change to better accommodate aging users.

  • Inclusive Design: Part 2 (at asktog.com)

    In Part One, I argued that accessibility should not focus just on the needs of the profoundly disabled, that well-crafted solutions can be of service to all. This new approach is called, “inclusive design” and it starts with organization.

  • Inclusive Design: Part 1 (at asktog.com)

    Have you ever thought about what it would be like to be disabled? Well, you better start thinking about it!

  • Accessibility Is Not Enough

    A strict focus on accessibility as a scorecard item doesn't help users with disabilities. To help these users accomplish critical tasks, you must adopt a usability perspective.

  • Lower-Literacy Users: Writing for a Broad Consumer Audience

    Lower-literacy users exhibit very different reading behaviors than higher-literacy users: they plow text rather than scan it, and they miss page elements due to a narrower field of view.
