ATutor was first released in late 2002. It came in response to two studies conducted by the developer in the years prior that looked at the accessibility of online learning systems to people with disabilities. Results of the studies showed none of the popular Learning Management Systems at the time even provided minimal conformance with accessibility guidelines. At the time a blind person for instance, could not participate fully in online courses.
Accessibility features Two, of many, accessibility features in the system are text alternatives for all visual elements, and keyboard access to all elements of the program. With these features, a blind person can listen to the entire interface of the system with the help of a
screen reader, and he or she can access the system without needing a mouse. These features also allow ATutor to adapt to a wide variety of technologies including cell phones, personal data assistants (PDAs), and text-based Web browsers, to name a few. ATutor includes a content authoring tool that prompts content developers to create accessible learning materials. Such prompts encourage authors to add a text alternatives if they forget to include one when adding an image, for instance. The authoring tool also includes a Web service that evaluates the accessibility of authored content against various international standards. In addition to creating accessible content, the tool is itself accessible, allowing a blind user to create content themselves.
Adaptability features ATutor is also designed for adaptability to any of several teaching and learning scenarios. There are four main areas that reflect this design principle: themes, privileges, tool modules, and groups. The ATutor theme system allows administrators to easily customize the look and layout of the system to their particular needs. Themes are used to give ATutor a new look, to give categories of courses their own look, or to provide multiple versions of ATutor on a single system, from which users could choose one as a preference setting. The privilege system allows instructors to assign
tool management privileges to particular members of a course. Instructors may create assistants or course tutors that had limited control over any of the authoring or management tools. == E-learning patent dispute ==
