mProducer: Authoring multimedia personal experiences on mobile phones

This paper presents the mProdueer tool that enables multimedia content authoring on mobile phones. It addresses three major challenges: limited storage space on mobile phones, costly and slow wireless links, and limited mobile user attention. Our contribution is twofold: (1) a novel technique called Storage Constrained Offloading (SCO) that intelligently uploads selected portions of contents to a remote storage server, so that the amount of contents a user can capture is not restricted by the size of the small mobile storage, and (2) two new UI techniques, the Key-frame based editing and automatically generated content navigation tree, to reduce the amount of user efforts for editing.
