Editor for accessible images in e-Learning platforms

In this paper, we present a set of twenty features for managing accessible images when generating educational content. With this set of features, we assessed a sample of eight e-Learning platforms and found that, regarding image accessibility, Moodle and Sakai are the most accessible e-Learning platforms, whereas edX and Udemy are the least accessible. We also present an HTML visual text editor for accessible images designed to be a base component across e-Learning platforms. As future work, we plan to propose additional sets of accessibility features regarding other formats, e.g. text, audio, video.
