mProducer: authoring multimedia personal experiences on mobile phones

The work presents the mProducer 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; limited mobile user attention. Our contribution is twofold: (1) a novel technique called storage constrained off-loading (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; (2) two new UI techniques, the keyframe based editing and automatically generated content navigation tree, to reduce the amount of user efforts for editing.
