STUDIES

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 inter-action supports users ’ navigation of previously-viewed intervals to construct new videos via simple playlists. The intervals in the history can be individually pre-viewed 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. In-terval selection and playlist creation using a history-based interaction is compared to a more conventional filmstrip-based technique. We performed several user stud-ies to evaluate the usability and performance of this method and found significant results indicating improvement in video interval search and selection. ii Preface All the implementation and experiements henceforth were conducted by myself. Concepts and design decisions were discussed among myself, Abir Al Hajri, Gre
