VidWiki is a project out of MSR India that leverages the crowd
to improve the quality and content of online video lectures like
those produced by Khan Academy, Coursera, EdX, and Udacity.
Through the online platform, users annotate videos by overlaying
content on top of the video. Annotations can be typed text,
LaTeX equations, shapes, images, or custom pen-drawn notes
directly on the canvas. Recent efforts by organizations like
Coursera, edX, Udacity and Khan Academy have produced thousands
of educational videos logging hundreds of millions of views in
their attempt to make learning freely available to the masses.
While the presentation style of the videos varies depending on
the author, they all share a common drawback: videos are time-
consuming to produce and cannot be easily modified after
release. With that in mind, we present VidWiki, an online
platform to leverage the massive numbers of online students
viewing videos to iteratively improve video presentation quality
and content, similar to other crowds
