Summary

Alt Text, which was added to the HTML tag set more than 25 years ago, was never designed to do what's needed for today's ICT graphics.

Current research presented by Karen McCall and Bevi Chagnon at last summer's ICCHP-AAATE 2022 conference honed in on Alt Text's shortcomings and inability to fully convey graphical information to end users.

The authors ask the community: "What can we do to fix it?"

Ditch it?

Fix it?

And if so, how?

Abstract

At the ICCHP-AAATE 2022 conference this past summer, Karen McCall (M.Ed, ADS) and Bevi Chagnon (MBA, ADS) presented their initial scholarly research on what’s needed to portray and convey complex graphical data to all end users, especially those with disabilities who use assistive technologies.

Their conclusion: Alt Text isn’t good enough.

In fact, it sucks.

(We stated it much more politely at the conference, but that was the true conclusion of the research.)

Not only are there no formal, industry-accepted guidelines on how to write Alt Text and what information it should contain, but the Alt Text technology itself is limited in what it can provide. Our websites, apps, documents and other digital media have dramatically changed since Alt Text was first added to the HTML 1.2 tag set in the mid-1990s. It's an antiquated technology.

Screen reader users have few controls over Alt Text. And by its design as an attribute on the or tag, it can’t do a satisfactory job of conveying complex charts, maps, data from GIS systems, info-graphics, or statistical analysis from data-visualization software like Tableau.

It’s time to rethink Alt Text.

Should we ditch it and create a better technology to convey this complex information? Is it possible to fix Alt Text's shortcomings and expand its capabilities? And how do we make these adjustments throughout the industry?

There are a lot of stakeholders in the accessibility industry — The standards committees for HTML, WCAG, PDF, PDF/UA, and EPUB; content creators; assistive technology manufacturers; software manufacturers (like Microsoft and Adobe); and end users themselves.

Join us as together, we (the community) take the next step — brainstorm a strategy that will improve this information and create better options for content creators and end-users. And get it accepted industry-wide.

Keypoints

  1. Present the findings of the authors' preliminary research on Alt Text.
  2. Define what might be holding Alt Text from being more "robust" and useful to end users.
  3. Review of some methods you can use now to improve the conveyance of complex data.
