Abstract

We propose the use of a personal video navigation history, which records a user's viewing behaviour, as a basis for casual video editing and sharing. Our novel interaction supports users' navigation of previously-viewed intervals to construct new videos via simple playlists. The intervals in the history can be individually previewed and searched, filtered to identify frequently-viewed sections, and added to a playlist from which they can be refined and re-ordered to create new videos. Interval selection and playlist creation using a history-based interaction is compared to a more conventional filmstrip-based technique. Using our novel interaction participants took at most two-thirds the time taken by the conventional method, and we found users gravitated towards using a history-based mechanism to find previously-viewed intervals compared to a state-of-the-art video interval selection method. Our study concludes that users are comfortable using a video history, and are happy to re-watch interesting parts of video to utilize the history's advantages in an authoring context.
