Registration is now open for the next DIAGRAM webinar:
Title: Tactile Graphics with a Voice
Date: Tuesday, February 24, 2015
Time: 11:00 a.m. Pacific (2:00 p.m. Eastern; 19:00 GMT)
Presenter: Richard Ladner, University of Washington
Description: Are you a publisher, tactile graphics expert, or TVI who is interested in staying up to date on the latest developments in accessible tactile graphics? The Tactile Graphics Project at the University of Washington, with funding from the DIAGRAM Center, has created “Tactile Graphics with a Voice” (TGV), a QR-code reading app that allows text within tactile graphic images to be read and voiced by a mobile device such as an iPhone or Android phone. In this webinar, lead researcher Richard Ladner will discuss the importance of tactile graphics, some alternative approaches to creating them, and give a demonstration of the TGV in action. A user study of TGV will be also be presented. Dr. Ladner will give us a peek into the future of new approaches to tactile graphics, including wearable devices such as Google Glass. See the published paper about this work, which won Best Student Paper at the October 2014 ACM SIGACCESS conference on computers and accessibility.

We may collectively look back on 2014 as the year that a tipping point was achieved in the widespread acknowledgement among mainstream publishers that accessibility of educational materials is not only critical but also achievable. It’s the year that Elsevier announced all images in 2015 publications will contain alt text. It’s the year that Pearson announced that MathML will be used in books produced in 2015 and beyond. It’s also the year that the Book Industry Study Group (BISG) established an Accessibility Working Group to create a “quick start guide” as a reference for all publishers who want to make their digital content accessible. The voices of all of us in the DIAGRAM Advisory Board and Working Groups have very much influenced this collective conversation. Because of your hard work all year, we are ever closer to achieving our goal of “born accessible” image content for current and future generations of students with disabilities.
Highlights from the year include:
- Debut of the new Accessible Image Sample Book
- Release of a new Poet Training Module
- Partnership with Microsoft and the American Mathematical Society to develop MathML Cloud
- Collaborating on updated goals during our 40-member DIAGRAM strategic planning meeting
- Addition of brand-new webinars on new models for creating accessible interactive widgets, how to use the Accessible Image Sample Book, and 3D printing for accessible educational materials
- Update of the popular guide to DTB Authoring & Reading Tools (a.k.a. the product matrices)
- New research on Accessible Dynamic Scientific Graphics and 3D Printing for Accessible Materials in Schools
- New tool development on JSWAVES and Description Templates for Common Graphics
- Re-introduction of the Content Model as Diagrammar: A Framework for Making Images and Graphics Accessible
For your part in all these accomplishments and so many more, we thank you. Onward and upward in 2015 and beyond!

MathML Cloud video
Earlier this fall, we created a very short overview video describing what MathML Cloud does and we put a version of it up on YouDescribe, the crowd-sourced video description tool created by our friends at Smith-Kettlewell Eye Research Institute. Be one of the first to see it, and let us know what you think. If you prefer, see the original version on YouTube (closed-captioned).
Editor’s Note: This is a summary of completed DIAGRAM subcontract work, submitted by Steve Landau. Find the full report and links to the surveys for the templates by visiting the DIAGRAM Development web page.

Rather than being expected to develop unique prose for each image they are tasked to describe, image describers should be supported to describe according to established guidelines. This will simplify their work, and may reduce cognitive load for readers. This project has created software that prompts describers with image description templates for common types of graphics, based on the NCAM STEM description guidelines. Image describers respond to questions regarding the basic characteristics of a diagram, and are guided through a fill-in-the-blanks process, which generates the first paragraph of an image description. The describer is then free to edit that paragraph and to append additional explanatory language. An assessment program built into the proposed project provides feedback on the consistency and accuracy of descriptions provided by users of the templates.
In analyzing the data generated during this study, the researchers determined that guided and unguided descriptions were equally likely to contain syntactic or content errors, contain text or table elements, and provide a description of the data and data trends. Guided and unguided descriptions were also equal in how long they took to create and their text word counts. However, guided descriptions were more likely to contain important image information, including the chart type, title, caption, and units. Furthermore, the participants found description using guidance/templates to be significantly easier, and they preferred this method over unguided description.
The current report assesses the production of image descriptions through unguided and guided interfaces, and compares the resulting descriptions on their accuracy and completeness. The guided descriptions were no more or less accurate than the unguided descriptions, but were more complete. The current research does not address whether unguided or guided descriptions promoted comprehension and usability. Further research will be needed to investigate what properties of descriptions work best for students and teachers, and whether these properties are encouraged or discouraged by our guided-description system.

“What is the Content Model, anyway?” we are sometimes asked. As those in the DIAGRAM community know, it provides a structured, standard way for image description data to be modeled, including multiple different types of descriptions for each image, teacher annotations, and pointers to tactile graphic files. Even though this model is used “under the hood” for content architecture and strictly speaking doesn’t require “branding,” we have long wanted to rename it so that it more intuitively conveys what it does and why it is important. We are therefore delighted to officially announce a new name for it: Diagrammar: A Framework for Making Images and Graphics Accessible. “Diagrammar” works on a number of levels – it has “diagram” in it, and it has “grammar” in it, and it suggests action!
Many thanks to George Kerscher for leading the charge, to Robin Seaman and Bryan Gould for taking the creative lead on brainstorming names, and to Gaeir Dietrich, who served as liaison from the DIAGRAM Outreach Working Group to help out with the renaming process. The Diagrammar web page has been updated to reflect the change.

Following last month’s ruling on the inclusion of @longdesc in HTML5, the W3C has moved the HTML5 Image Description Extension forward to Proposed Recommendation status. See http://www.w3.org/TR/html-longdesc/ for the document itself. The implementation report is also available. Note that the comment period for this extension specification ends on January 16, 2015. Assuming no further objections are received, the W3C may publish the final recommendation shortly thereafter.
Although not new for December, back in September the WAI announced the availability of its Web Accessibility Tutorial on Images. The tutorial offers users basic guidance on how to write effective text alternatives for informative, decorative or functional images. Other tutorials are available at http://www.w3.org/WAI/tutorials/.

The DIAGRAM Standards Working Group continues to meet jointly with the TIES (Transition to Inclusive EPUB 3 eco System) Working Group on a biweekly basis, every other Tuesday, preparing for the upcoming EPUB 3.1 revision, scheduled to be completed in 2015. The next joint DIAGRAM and TIES working group meeting will take place January 6, 2015 at 15:00 UTC.
From the accessibility perspective, we have been working on requirements for the next revision. The items under development are:
- updating the image description techniques; this has a dependency on W3C’s
decisions on the proposed ‘longdesc’ attribute and work currently underway on ARIA 1.1 including the ‘aria-describedat’ attribute
- further braille enhancements, with dependencies on CSS development, and the
standardization of braille code identifications
- enhancements to media overlays, which may include text and video
synchronization for sign language. Also, metadata extension to identify the
type of media overlay, e.g. text and audio, text and sign, text and video or
- further development and promotion of audio only EPUB (with navigation) and
addition of modern audio codex
- development of samples that demonstrate techniques used for creating accessible publications in EPUB 3.1 format
Readium will be holding meetings at the New York Public Library on January 13 and 14, 2015.

Outreach Working Group Update: Telling Our Story
The DIAGRAM Outreach Working Group met on December 18, 2014 with special guest speakers Maureen Hawes and Mike Sharpe, who both serve as DIAGRAM program evaluators. We asked them to talk with us about the best way to measure what impact DIAGRAM has had on the field. The answer came back an unequivocal: Storytelling! Don’t be surprised if we reach out to soon to ask, “What would the world have been like if DIAGRAM had not been established five years ago?” As we approach our final year of the DIAGRAM award, we will be collecting your ideas and observations to compile our story. Contact Outreach Working Group Chair Julie Noblitt at julien [at] benetech [dot] org if you would like more information. As always, the DIAGRAM Outreach Working Group wiki is the place to find our past meeting notes.
DIAGRAM Webinar Series Continues in 2015
The DIAGRAM webinar series will resume in the new year with two topics that will be of interest to those who like to stay abreast of breaking new technologies in print accessibility. In the queue is a webinar with haptics experts from ETS and Senseg on new ways that haptic feedback can enhance learning materials. Also coming up, hear the latest research from the University of Washington’s Tactile Graphics Project, whose paper. “Tactile Graphics with a Voice” recently won a best student paper award at the ASSETS 2014 conference. Stay tuned for dates and registration announcements for these webinars in the new year.
Here are a few items that caught our attention in the last month:
- Wonderful TEDx talk by Chelsea Cook, a blind physics student from Virginia Tech who talks about how 3D printing made complex math concepts clear to her for the first time, including some great in-classroom footage of the teacher-student interaction where she has her “aha” moment – very moving: “Touch the stars”
Earlier this year we reported that Richard Ladner’s DIAGRAM research was completed on a tool that converts image labels into a QR code that can be affixed to a graphic, allowing the image to be read and voiced by a smart phone. A paper has now been published about the work, which is part of the Tactile Graphics Project at the University of Washington. The paper is available as open access until early October 2015 and after that it is closed in the ACM Digital Library. Retrieve it here: http://dl.acm.org/citation.cfm?id=2661334.2661366
Catherine M. Baker, Lauren R. Milne, Jeffrey Scofield, Cynthia L. Bennett, and Richard E. Ladner. 2014. “Tactile graphics with a voice: using QR codes to access text in tactile graphics.” In Proceedings of the 16th International ACM SIGACCESS conference on Computers & accessibility (ASSETS ’14). ACM, New York, NY, USA, 75-82.
The paper was awarded Best Student Paper at the ASSETS 2014 conference this month. According to Dr. Ladner, a version of the iPhone app TGV to help read QR-codes will be in the App Store soon, and an updated version with a finger pointing feature should be in the store in a couple of months. Congratulations to Richard and his team!
