Inclusivity and availability have always been central to our mission. We’ve worked hard to design and develop Hypothesis to reduce geographic, financial, or logistical barriers to users who want to read and write annotations on the web. That’s why Hypothesis is built on open web standards, will always be free to use, and works on a wide range of formats and platforms.
We consider accessibility to be a key part of a larger effort to practice and promote what many are now calling “inclusivity.” We work to increase the accessibility of annotation through inclusive design, a practice defined by the Inclusive Design Research Centre as “design that considers the full range of human diversity with respect to ability, language, culture, gender, age and other forms of human difference.” Following inclusive design, we look to make interventions not only to support accessibility for specific types of users, but to make annotation a better and easier experience for everyone.
- Engage with users for whom Hypothesis software has failed to provide an inclusive experience
- Real-world testing and feedback
- Collaboration with people and organizations that care about accessibility and inclusivity
- Standards/guidelines compliance
- Inclusive design as an integral part of everyday development
- Transparency: clear, public communication about the approach, status, and plans for accessibility and inclusiveness at Hypothesis
Areas of Accessibility
Hypothesis focuses on accessibility in five general areas that together encompass the full range of interactions people have with annotation.
Hypothesis seeks to enable annotation on all web content — already including HTML web pages, PDFs and EPUBs, but with plans to expand to images, video and other formats. We recommend you consider the accessibility of the materials you make available for annotation, especially if you are asking others to participate. For example, HTML web pages are likely to be more accessible than PDFs. PDFs can be made more accessible. EPUBs may have differing levels of accessibility. Before you consider annotation, you can test the accessibility of content.
Enabling people to annotate privately and with others, both in environments where Hypothesis is embedded and ready to use, and using browser extensions that enable annotation across the web, including activities like:
- Accessing Hypothesis
- Establishing Hypothesis accounts
- Resetting/changing passwords
- Changing emails
- Changing usernames
Enabling people to find and read existing annotations, including activities like:
- Viewing highlights
- Viewing annotations
- Viewing page notes
- Viewing orphans
- Searching annotations
- Reordering annotations (newest, oldest, location)
Interacting with Annotations
Enabling people to engage with existing annotations, including activities like:
- Replying to annotations
- Sharing annotations
Enabling people to create their own annotations, including activities like:
- Changing group context
- Selecting text
- Creating highlights
- Creating annotations
- Formatting annotations
- Editing annotations
- Deleting annotations
Hypothesis is collaborating with the Inclusive Design Research Centre (IDRC) to map and improve the current accessibility status of our services. After an initial review of Hypothesis functionality in relation to WCAG 2.0, we have brought our annotation client into compliance with Level AA Success Criteria set out by the W3C in the Web Content Accessibility Guidelines (WCAG) 2.0. For our users in the United States of America, these criteria meet current standards defined by Section 508 of the US Federal Rehabilitation Act and provide more specific guidelines for complying with those standards
Please note that while the context of the review conducted by the IDRC was annotating within the Instructure Canvas LMS, the functionality and accessibility issues reviewed pertain to annotation in any context. Because the review took place in Canvas with Hypothesis already embedded and ready to use, it does not address “Getting Started” interactions, which we plan to review in the future.
The IDRC has conducted a final, independent review of our annotation software to confirm WCAG 2.0 AA compliance.
We will continue to update the new help area of our website to include accessibility guidance developed in our reviews and collaboration with IDRC and others.
We review and update our Vendor Product Accessibility Template (VPAT) on a regular basis to ensure it reflects accessibility-related developments.
We will continue to seek feedback from users who have disabilities and/or use assistive technology to ensure a good user experience rather than relying solely on compliance and “box-checking.”
Learn More and Get Involved
We welcome feedback on our approach and roadmap for accessibility and inclusivity. If you have difficulties using Hypothesis annotation and/or use assistive technology to interact with the web, we would love to hear your suggestions about how we could improve your experience.
