Detail-on-Demand Hypervideo


We demonstrate the use of detail-on-demand hypervideo in
interactive training and video summarization. Detail-on-demand
video allows viewers to watch short video segments and to follow
hyperlinks to see additional detail. The player for detail-ondemand
video displays keyframes indicating what links are
available at each point in the video. The Hyper-Hitchcock
authoring tool helps users create hypervideo by automatically
dividing video into clips that can be combined in a direct
manipulation interface. Clips can be grouped into composites and
hyperlinks can be placed between clips and composites. A
summarization algorithm creates multi-level hypervideo
summaries from linear video by automatically selecting clips and
placing links between them.
