Localization Lab

Secure Usability and Accessibility Lab

Our Secure Usability and Accessibility Lab offers secure usability and user-interface assistance, and accessibility assessments to internet freedom and digital security tools to help them recognise and solve usability and accessibility challenges that hamper tool adoption in repressive contexts.

About the Secure Usability and Accessibility Lab

Open-source internet freedom technologies aim to help people around the world – such as activists, journalists, and everyday citizens – to communicate with better privacy and security. However, many of these technologies need assistance to be truly usable and accessible in various contexts across diverse communities. Lack of usability and accessibility results in slow adoption of these technologies and increases the gap between technology developers and users. Additionally, misunderstandings of tool functionalities can potentially lead to a false sense of privacy and security.

We partner with service providers to offer in-kind, secure usability and accessibility services to OTF-funded projects and other internet freedom technologies to make their tools accessible to a global audience.

How to Apply

The Secure Usability and Accessibility Lab services are available directly via our lab partners. We encourage you to review the lab service partners information and services below and, according to your needs, get in touch with one of them directly. If you have general inquiries about the Lab please contact [email protected].

Our partners provide the following services as an in-kind resource to OTF-funded projects and other internet freedom technologies:

Service #1: Secure Usability and Accessibility Coaching

Guidance, feedback, and support on your secure usability and accessibility practices, and assistance for your team to engage in more effective strategy, design, and development in the longer-term.

Service #2: Secure Usability and Accessibility Consultation

Hands-on, secure usability and accessibility support. This includes user research, UX design, accessibility implementations, and other design services that you may benefit from.

Service #3: Secure Usability and Accessibility Audits

Discover how to improve the usability and accessibility of your tool. Audits assess the usability of the tool in relation to standards and best practices; highlight problems and suggest areas for improvement; analyze and identify pitfalls that might make it difficult for users under threat to use your tool; and help you better understand the needs of users and articulate them in the design of your tools.

Knowledge Sharing

To help the advancement of all communities and the accumulation of practical knowledge through peer-to-peer learning, the outputs of all coaching, consultation and audits will be publicly documented upon completion.
