Abstract

As small portable devices are becoming standard personal equipments, there is a great need for the adaptation of information content to small displays. Currently, no good solutions exist for viewing formatted documents, such as pdf documents, on these devices. Adapting content of web pages to small displays is usually achieved by complete redesign of a page or automatically reflowing text for small displays. Such techniques may not be applicable to documents whose format needs to be preserved. To address this problem, we propose a new document representation called Multimedia Thumbnail. Multimedia Thumbnail uses the visual and audio channels of small portable devices to communicate document information in form of a multimedia clip, which can be seen as a movie trailer for a document. Generation of such a clip includes a document analysis step, where salient document information is extracted, an optimization step, where the document information to be included in the thumbnail is determined based on display and time constraints, and a synthesis step, where visual and audible information are formed into a playable Multimedia Thumbnail. We also present user study results that evaluate an initial system design and point to further modification on analysis, optimization, and user interface components.
