“The SDK is open source and can easily be used by accessibility researchers and developers alike. Why not try it?” ACTF is a framework that serves as an extensible infrastructure upon which researchers can build a variety of utilities that help to evaluate and enhance the accessibility of applications and content for people with disabilities. A collection of example utilities are also provided which were created on top of the framework such as compliance validation tools, assistive technology simulation applications, usability visualisation tools, unit-testing utilities, and alternative accessible interfaces for applications.
