Annotating Live Video with Tablet Computers: A Preliminary User Study
Tablet computers provide a natural support for digital annotation associated to any type of media, including live video. However, annotations of live video require real-time motion tracking, maintaining the association between annotations and moving objects, as well as interfaces that facilitate the annotation task of a live event. This work presents the initial users' feedback on a video annotator that includes two real-time trackers, Kinect and TLD, and on two annotation methods that aim to help annotating live video, "Hold and Overlay" and "Hold and Speed Up".
