One-handed mobile video browsing

Various situations exist in which people want to use just one hand when interacting with their mobile phones or PDAs. However, most of the few advanced video browsing approaches for such devices only support two handed operation. In this paper, we present an interface design for one-handed mobile video browsing. Using a PDA with touch screen, users can interactively scroll through a list of thumbnails representing the video's content. Thumbnail sizes can be manipulated in order to provide easier access to relevant information. Two evaluations are presented which motivate the design and verify the usability of our solution.
