URGENT request for help: I need to build a case (soon) that justifies the "broader impact" of my research (yes, this is related to recent events in the US). If you have ever used Chartability or Data Navigator in your work in any capacity, I would love to know! Please email ([email protected]) or dm me.

This looks like a fantastic (and FREE!) #a11y workshop organized by the lovely folks at @smashingmagazine.com and featuring some *amazing* experts: @stephaniewalter.bsky.social @fossheim.bsky.social Kardo Ayoub Sadly, I'm not able to attend, but you should! smashingconf.com/meets-access... #ux

"Disabled users don't use my website" is a cop-out and a lie. There's no way to know how many assistive technology users are using your site. You can't confidently exclude a large portion of the world's population that has a disability by claiming none of them use your site.

Don't forget to register for your free ticket to Smashing Meets Accessibility, streaming on Thursday February 20th at 8AM PT (4PM GMT). @geoffgraham.me will be hosting talks from @fossheim.bsky.social, @stephaniewalter.bsky.social, and Kardo Ayoub. smashingconf.com/meets-access... #Accessibility

Make sure that interactive elements that can be accessed by using a mouse, pen, trackpad or touch are at least 24 by 24 CSS pixels. This helps people with low vision and/or limited motor control select the intended element without accidentally selecting nearby elements.

A sign that accessibility and data viz is important: the most downloaded episode of the Data Stories Podcast ( @moritzstefaner.bsky.social @ebertini.bsky.social ) is the episode about accessibility with the amazing @fossheim.bsky.social Check out the data: observablehq.com/@moritzstefa...

USA peeps, please figure out how to navigate the ongoing crisis/coup in a way that keeps you as healthy as possible. Do not listen to the scolds who tell you you have to rage 24hrs/day or you are complying. Pace yourself. Have a nice meal, laugh with friends, discuss a book. This will be a long haul

I'm studying for the CPACC, any tips? #CPACC #IAAP #accessibility

Color can be a great way to distinguish data points in charts. But don't rely on color alone to convey information, as that can make things difficult for colorblind users. Using different shapes or patterns can help. Make sure patterns or textures are simple and not distracting.

Things I want to happen when I click "unsubscribe" in an email: - unsubscribe me Things I don't want: - login to "manage my preferences" - unsubscribe me from [obscure list 1 of 17] - email me again to ask if I unsubscribed by accident (it's never by accident)

People who want to make the web accessible need to understand the many different ways that people with disabilities use the web. This W3C resource offers a good introduction to how disabled people navigate the web, and barriers they commonly encounter. www.w3.org/WAI/people-u...

Male and female gulls look identical, but it’s possible to tell the difference based on the size of the head and bill 🤓 That’s how we learned that balcony gull Gloria, who recently got measured & ringed, is actually a boy! Blog: fossheim.photography/blog/2025-01... #ornithology #birdPhotography

"Everybody - wake up! It's the #BigGardenBirdwatch!" Will you be taking part today? 👀🌳

If you'd like to support my work like this thread, I don't have a paid newsletter YET. But I'm currently fundraising for my family's February bills so I can build and launch it! Latest progress update: $1,616 / $3000 53.9% to goal More #TheAccessibilityPond info: ashleemboyer.com/blog/help-me...

If you pardon hundreds of violent neo-nazis and give your un-elected BFF a platform to give a Nazi salute (twice) during your inauguration, then you’re a neo-nazi. This is not hyperbole. Dismissing it or excusing it is enabling neo-nazis, their violent past, *and* their violent future.

The TikTok ban, the Musk Twitter takeover, the Facebook moderation policy changes, the Republicans’ rapidly intensifying crackdowns on speech... let these be the proof you needed to move anything you care about online to a space you control. Digital sovereignty is more important than ever.

Pixelfed as an instagram alternative for wildlife photography: yes/no, and anyone has good server recommendations? Kinda tempted to just stick to my own website, and the occasional sharing to mastodon/BlueSky/flickr though 🤔

A white-tailed eagle started scouting the area for prey, which caused the auks to flee their cliff in a panic. But not this one bridled individual, who bravely and proudly made their way back to the nest with their own fresh meal 🎣 #birdPhotography #wildlife #birds

You don't need permission to make things accessible. Leave files better than you found them #a11y

Next month I'll be talking about common dataviz accessibility mistakes and what we can do to prevent them, at Smashing Meets Accessibility ✨ It's online and free to attend: smashingconf.com/meets-access...

Meet the Arctic Tern, a bird that breeds in the arctic and overwinters in the antarctic, completing a distance similar to 3+ roundtrips to the moon in its lifetime. And if you ever met one, you probably understand why I call them Arctic Terrors instead 😰 #birdPhotography #birds #photography

Accessibility and intersectionality with @priyanca.bsky.social (dedicated to Vicky Teinaki). We discuss #dyscalculia, intersectionality, and the complexities of managing multiple access needs, as well as common service barriers and tips for designers. accessiblenumbers.com/accessibilit...

After 15 months of genocide.

Bird of the day: the razorbill, closest living relative to the extinct Great Auk. Razorbills are also vulnerable, having seen a >30% population reduction in Norway the last 50 years. Over half of Norway's seabirds are threatened, and 80% have disappeared from bird cliffs. #photography #ornithology

There is not one font that will be optimal for all users with dyslexia. Experts disagree on which fonts provide the best readability. But simplicity in typefaces is critical. Ideally, use fonts that are familiar or at least easily-parsed so that they quickly become familiar.

Interactive dyscalculia persona 👩🏻‍💼 Follow Helena as they try to pay for car mileage using an inaccessible service. Thanks to Faye Gardner and the HMRC accessibility team. So happy to be involved in this.

Black-legged kittiwake chick, photographed at a "kittiwake hotel" last summer. The kittiwakes have started breeding inside towns, and in order to prevent them nesting on people's houses, hotels were built for them. fossheim.photography/photos/catal... #birdPhotography #wildlife #photography

People often ask what accessibility considerations to keep in mind when creating data visualizations. For guidance and advice, check out Sarah L. Fossheim's list of 10 things to do (or not do) when designing accessible data visualizations. fossheim.io/writing/post...

I post lots about alt text as disability justice. You should use it on all images and enable the “require alt text” setting. But if your username uses a fancy font, is full of emojis, or has other tedium for screen readers, all your posts are inaccessible, even if you use alt text. Listen to it:

Been flying through books since getting a Kobo for Christmas. Starting (and maybe also finishing) Atalanta by Jennifer Saint today 🏹

You’re telling me this life crisis is mid?

For screen readers to recognize headings, heading text can't just be body text or normal text that's been made to look bigger and bolder. It must be formatted as a heading. In Microsoft Word and Google Docs, this can be done in the styles box. In HTML, use the tags h1 through h6.
