While predictions abound that electronic books will supplant traditional paper-based books, many people bemoan the coming loss of the book as cultural artifact. In this project we deliberately keep the affordances of paper books while adding electronic augmentation. The Listen Reader combines the look and feel of a real book - a beautiful binding, paper pages and printed images and text - with the rich, evocative quality of a movie soundtrack. The book's multi-layered interactive soundtrack consists of music and sound effects. Electric field sensors located in the book binding sense the proximity of the reader's hands and control audio parameters, while RFID tags embedded in each page allow fast, robust page identification.

This paper presents an automatic system for analyzing and annotating video sequences of technical talks. Our method uses a robust motion estimation technique to detect key frames and segment the video sequence into subsequences containing a single overhead slide. The subsequences are stabilized to remove motion that occurs when the speaker adjusts their slides. Any changes remaining between frames in the stabilized sequences may be due to speaker gestures such as pointing or writing, and we use active contours to automatically track these potential gestures. Given the constrained domain, we define a simple set of actions that can be recognized based on the active contour shape and motion. The recognized actions provide an annotation of the sequence that can be used to access a condensed version of the talk from a Web page.

Where Were We" is a prototype system that exploits the capabilities of digital video to allow groups to include recordings of very recent events into real-time activities.The goals of the research are to see how playback-while-recording and random access capabilities might substantially alter the activity of group work, to discover what difficulties arise in using emerging digital multimedia hardware and software facilities for this kind of application, and to further explore how to base novel systems design on necessarily partial and fragmented observations of actual work activity.The implications of this work on systems architecture has been both to inform the design of digital multimedia tools and to suggest different factorings of computation, display, storage, and transmission.The prototype is now stable enough for use in exploratory settings, and we are poised to see how (and verify that) design groups can make use of these "instant replay" facilities in real working situations.

A multi-user drawing tool was used by participants in a distributed design exercise conducted in a multi-media working environment.The goal of the study was to explore how observations from our earlier studies of shared drawing in two-person design activity would hold up when three participants worked together.Additionally, the study provided opportunities to contrast video/audio connections with audio-only connections and to discover new behaviors that emerge in the use of new technologies.Participants successfully used the shared drawing system with no observed difficulties attributable to the addition of a third user.Audio-only connections appeared to adequately suppofi this work activity, but details of the participants' interactions in the exercise raised questions that deserve further study.Finally, observations suggest that drawing tools such as the one reported here may offer support for alternative forms of participation in collaborative work.

This paper describes VideoDraw, a shared drawing tool, and the process by which it is being designed and developed.VideoDraw m a video-based prototype tool that provides a shared "virtual sketchbooks" among two or more collaborators.It not only allows the collaborators to see each others' drawings, but also conveys the accompanying hand gestures and the process of creating and using those drawings, Its design stems from studying how people collaborate using shared drawing spaces.Design implications raised by those studies were embodied in a prototype, which was subsequently observed in use situations, Further research studying the use of VideoDraw (in comparison with other collaborative media) will lead to a better understanding of collaborative drawing activity and inform the continued techmcal development of tools to support collaborative drawing.

This paper describes VideoDraw, a shared drawing tool, and the process by which it is being designed and developed. VideoDraw is a prototype, videobased, tool that provides a shared “virtual sketchbook” among two or more collaborators. It not only allows the collaborators to see each others' drawings, but also conveys the accompanying hand gestures and the process of creating and using those drawings. Its design stems from studying how people collaborate using shared drawing spaces. Design implications raised by those studies were embodied in a prototype, which was in turn observed in use situations. Continued research studying the use of VideoDraw (in comparison with other collaborative media) will lead to a better understanding of collaborative drawing activity and inform the continued technical development of VideoDraw.
