SEARCHABLE ANNOTATIONS-AUGMENTED ON-LINE COURSE CONTENT

摘要

A method for augmenting or enhancing on-line course content includes displaying an on-line education course video to one or more viewers on network-connected viewing devices, receiving viewer annotations data including viewer annotations of video fragments, segments or frames of the displayed course video, and accumulating the viewer annotations data as annotation data records in in a searchable database. Each annotation data record includes annotation text for a respective video fragment, segment or frame of the displayed course video to which the annotation text applies. When a user query or search term has a match in the annotation text in an accumulated annotation data record, the method returns a search result based on information in the accumulated annotation data record including a link to the specific video fragment of course video to which the annotation text applies.
