The Data Visualization Task Force’s goals are to create a shared understanding of the landscape of existing accessibility techniques for data visualization, extend these state-of-the-art techniques, and develop a best practice guide for creating accessible data visualizations. This year we began work on a Google document showcasing the state of the art with respect to accessible data visualizations. We will continue this effort in 2019 and create our best practices document.
The Drag and Drop Task Force has continued working on three documents started in late 2017. The first is an analysis document that provides an overview of current issues regarding accessible Drag and Drop Interactions. Accompanying this document are two supporting documents classifying the various drag and drop interactions in terms of difficulty level along with examples. In 2019, the group will combine these documents into a single, cohesive web document, which will be used to create a set of best practices and guidelines on when and how to use them.
The Developers Working Group finalized a technique for making math accessible in EPUBs. It allows publishers to present math equations as an image with an alt-text description of the math. For reading systems and eReaders that can understand MathML, it provides improved access to the content when using assistive technology. The technique has now been incorporated into a new accessible Math EPUB test book. In January the book will undergo testing on a variety of reading systems, platforms and assistive technology combinations in order to determine feature compatibility. The results of these tests will be published on the epubtest.org accessibility results page, as well as in DIAGRAM’s Math Support Finder.
The Developers Working Group also helped plan the 2018 DIAGRAM Code Sprint with many participating as well. Members from the group are continuing work on various projects, including one that converts spoken math into an accessible digital version using machine learning. Another project builds a speech priority queue that the University of Colorado PhET team has already begun to incorporate into some of their accessible STEM simulations. The Developers Working Group will continue discussions and support the planning for the 2019 DIAGRAM code sprint soon after the new year.

Dr. Yue-Ting Siu (Ting to those she knows, Dr. Ting to her students) has been a long time member of the DIAGRAM Community. She first became involved in 2012 when she worked as a consultant on Poet’s former iteration as an image description tool. Her role with DIAGRAM has always been around translating educational needs and classroom practices for DIAGRAM Development, and deciphering DIAGRAM tools and technology making them usable for teachers. In addition to contract work, over the years Ting has volunteered her time to participate in the Content Working Group, the Tactile Working Group, the Outreach Working Group, and the Advisory Committee, as well as strategic planning meetings and other DIAGRAM, hosted events. I had the opportunity to sit down with Ting and learn more about what she does when she is not participating in DIAGRAM activities.
Ting is an assistant professor and is in her 3rd year coordinating the Visual Impairments (VI) Program within the Department of Special Education at San Francisco State University where she trains teachers of the visually impaired who are getting their teaching credentials or pursuing Masters degrees. At the start of 2018 she was in the process of majorly refreshing the VI course curriculum, especially in regards to technology. She wanted to make sue that learning to use technology was integrated throughout all coursework with different courses focusing on different technology aspects.
Ting also believes very strongly that students need to graduate from the program not only prepared to teach, but able to keep evolving their own professional development in order to remain relevant in their practice. According to Ting, this is even more important for teachers of the visually impaired who are often much more isolated in their fields. Most TVIs are itinerant, meaning they travel from school to school to see students, a practice that can easily cut them off from the informal professional development that happens in schools as well as professional community building in general.
Thanks to Ting’s efforts, TVI students in her program are now learning about multimedia accessibility throughout the program, even making video tutorials to share with colleagues in the field. There is also an added emphasis on learning to connect and staying connected with the professional learning community via social media. The program upholds accessibility standards so that learning materials are provided to students in an accessible format, including the learning management system and the use of the Zoom video conferencing platform for all classes. All students’ work also meets standards for accessibility including the dissemination of accessible reports and use of image and video description in all course projects. In addition, the program has a rolling admissions process and is now delivered via synchronous instruction on Zoom with face-to-face Lab Weekends once per semester. For those wanting more information on the TVI program at SF State, updates can be followed on Facebook, Twitter, Instagram and YouTube by searching for @VIProgramSFSU.
As mentioned in our August newsletter, the Second Annual DIAGRAM Report has been published and is available on our website along with the 2017 report. But as the saying goes, there is no rest for the weary, and our team has already begun work on the third annual report. We have reached out to many of our community members to solicit feedback on the technologies we should explore for the 2019 report and find out who might be interested in writing a section for the report on a technology you feel passionate about. If you haven’t received a survey and wish to provide your opinion, please let us know. You can email your input to CharlesL[at]Benetech[dot]org. Don’t be shy; the more feedback we get, the stronger the report will be!
By now, many of you are familiar with Imageshare, an open source platform DIAGRAM created for educators and consumers to find and share alternative image resources related to key science, technology, engineering, and mathematics (STEM) concepts. The tool aims to curate STEM materials frequently encountered in the classroom and allows users to search the collection using accessible metadata (e.g., contributor, resource type, target grade(s), and language). The new version of Imageshare also adds the ability for educators and end users to add instructional teaching notes, production notes, as well as usability ratings and comments for specific resources.
Imageshare was soft launched at the end of August and is now live and ready for more content! More STEM resources will continue to be added, with content feedback to be provided by additional students and educators in the coming months. To date, the College of the Desert and employees of LightHouse for the Blind in San Francisco have already provided input on the usability of 3D-printed models identified and produced by DIAGRAM’s Tactile Working Group. Further testing with end users has been scheduled with the Texas School for the Blind and Visually Impaired and other academic institutions aiming to better understand accessible educational alternatives. In addition to contributing and evaluating content, members of the Tactile Working Group have also helped test the accessibility and usability of the Imageshare platform, and we thank this group for their active participation the development of this tool.
The DIAGRAM Center has been exploring whether it’s possible to make complex diagrams more appealing and engaging for tactile learners by adapting the 2D tactile graphics production process for non-braille learners. Innate in the traditional 2D production process are the simplification of visual content and the removal of things like clutter and perspective. These simplified graphics have the potential to better support students with special needs such as: cognitive disabilities, learning differences, autism, and low vision. While best practices highlighted in the Braille Authority of North America (BANA) guidelines for 2D tactile production process were applied in the experimental resources, several non-traditional versions were also created for testing: a version where braille is replaced by English text, a version where texture is replaced by vibrant colors, a version combining texture and color, and a version that provides a higher-level context of the original graphic.
The DIAGRAM Center has been working with Lucia Hasty from Rocky Mountain Braille Associates and Nicole Johnson, formerly with Central Access at Central Washington University and now a Ph.D. student at the University of Colorado, Boulder, on this project. A working draft of the design principles and assumptions used to produce these resources will be shared as this project progresses.
We are thrilled to announce that version 2 of the Mathshare prototype is now available! Highlights in the recent release include updating the visual design to be more student-friendly, adding a workflow that supports teacher-generated problem sets, and allowing students to save, share, and revisit their work. While development of Mathshare is ongoing, with additional curriculum and accessibility improvements expected in the coming months, we look forward to sharing our updated tool with edtech companies and piloting the updated version in general and special education classrooms. If you are interested in piloting the new version of Mathshare in your classroom, with specific students, or connecting us with an edtech platform provider in the coming weeks, contact firstname.lastname@example.org.
It is with great pleasure that we announce the development of a new tool, the Custom Search Engine for Accessibility (formerly known as the “DIAGRAM Wizard”), which is designed to help publishers, content creators, and developers search for and find resources on how to make their web pages and EPUB books accessible. Incorporating a list of leading authorities in the creation of accessible materials as well as working examples, best practices, and information on standards, the tool is a customized Google search with a narrow focus, ensuring that users have a high probability of finding a vetted resource that can best support their needs in creating accessible material. Still in the early stages, the tool searches both the DIAGRAM Center website and the DAISY Knowledge Base with the hope of adding additional resource libraries in the near future.
On October 10, 2018, President Trump signed the U.S. ratification of the Marrakesh Treaty (formally known as the Marrakesh Treaty to Facilitate Access to Published Works for Persons who are Blind, Visually Impaired, or Otherwise Print Disabled). This is a major milestone in a process that started ten years ago to create a treaty enabling authorized entities like Benetech to share accessible materials across international borders through our Bookshare program. Prior to this treaty, any books that were created using a national copyright exception like the Chafee Amendment were limited to distribution only in the country where they were made accessible. You can read the full announcement on Benetech’s website.
The Tactile Working Group has been instrumental in contributing to the success of the Imageshare project. Members have contributed resources to the collection, tested the alternative content with end users, and provided comments about the usability of resources to be added to the collection. The group has also helped test the Imageshare platform and are continuing to work on adding resources and collecting feedback about the materials.
The Outreach Working Group finished content development and construction of the new community web page, which highlights the DIAGRAM tools and resources most applicable to each of the DIAGRAM stakeholder groups: educators, parents, students, publishers, developers, and researchers. We encourage those who have used this new resource page to provide us with feedback on its usability and the content it recommends. Comments can be sent to email@example.com.
The Developers Working Group has been increasing the examples in the Accessible Code Repository by adding a dozen new resources since the 2018 DIAGRAM Code Sprint, which took place this past June. Thanks to their hard work, the repository now includes over twenty examples of prototypes, code samples, and best practices for producing accessible educational materials. For those interested in the projects that were completed during the code sprint, even the ones that were not added to the repository, demo pages and summaries are available at 2018 Code Sprint Projects.
