Seamless Documents

Viewing documents on small and large displays

The Seamless Documents project develops a variety of techniques to support viewing documents and document collections on small and large displays.

Seamless Document Viewer

The Seamless Document Viewer integrates an array of novel techniques to support document viewing on mobile devices.

SeeReader

SeeReader allows users to read documents while maintaining an awareness of their environment.

CollectionViz

CollectionViz is a faceted browser designed to support browsing document collections on mobile devices.

The current trend toward high-performance mobile networks and increasingly sophisticated mobile devices has fostered the growth of mobile workers. In mobile environments, an urgent need exists for handling documents using a mobile phone, especially for browsing documents and viewing Rich Contents created on computers. This paper describes Seamless Document Handling, which is a technology for viewing electronic documents and Rich Contents on the small screen of a mobile phone. To enhance operability and readability, we devised a method of scrolling documents efficiently by applying document image processing technology, and designed a novel user interface with a pan-and-zoom technique. We conducted on-site observations to test usability of the prototype, and gained insights difficult to acquire in a lab that led to improved functions in the prototype.

Reading documents on mobile devices is challenging. Not only are screens small and difficult to read, but also navigating an environment using limited visual attention can be difficult and potentially dangerous. Reading content aloud using text-to-speech (TTS) processing can mitigate these problems, but only for content that does not include rich visual information. In this paper, we introduce a new technique, SeeReader, that combines TTS with automatic content recognition and document presentation control that allows users to listen to documents while also being notified of important visual content. Together, these services allow users to read rich documents on mobile devices while maintaining awareness of their visual environment.

Recorded presentations are difficult to watch on a mobile phone because of the small screen, and even more challenging when the user is traveling or commuting. This demo shows an application designed for viewing presentations in a mobile situation, and describes the design process that involved on-site observation and informal user testing at our lab. The system generates a user-controllable movie by capturing a slide presentation, extracting active regions of interest using cues from the presenter, and creating pan-and-zoom effects to direct the active regions within a small screen. During playback, the user can simply watch the movie in automatic mode using a minimal amount of effort to operate the application. When more flexible control is needed, the user can switch into manual mode to temporarily focus on specific regions of interest.

We present an automatic zooming technique that leverages content analysis for viewing a document page on a small display such as a mobile phone or PDA. The page can come from a scanned document (bitmap image) or an electronic document (text and graphics data plus metadata). The page with text and graphics is segmented into regions. For each region, a scale-distortion function is constructed based on image analysis of the signal distortion that occurs at different scales. During interactive viewing of the document, as the user navigates by moving the viewport around the page, the zoom factor is automatically adjusted by optimizing the scale-distortion functions of the regions visible in the viewport.
