Smart cards have been successfully deployed in Europe and Asia. The European Community considers them imperative and is funding 65 card development projects. In the US, however, the cards hold less interest and have been less successful. Technology diffusion research indicates social learning is critical to adoption. A small cadre of early adopters, through visible daily use of new products, creates a perception among other consumers that new products are beneficial and desirable. This study developed and deployed the Sony Wave Smart Card, a Sony FeliCa-based technology smart card Customer Relationship Management (CRM) application. The study involved US early adopters, 30% of whom adopted and sustained use of the card for six months. These early adopters appear prepared to seed the market. The paper describes the product development and research methods used in this study and the potential to deploy the product into a high density social environment with desirable applications to stimulate broader adoption.

Video widgets are user-interface components rendered with video information. The implementation and several usage examples of a family of video widgets, called video actors, are presented. Video actors rely on two capabilities of digital video: non-linear access, and the layering of video information. Non-linear access allows video frames to be displayed in arbitrary order without loss of continuity, layering allows two or more video streams to be spatially composed. Both capabilities are now becoming available to user-interface designers.

Digital video consists of temporally correlated audio and visual data elements. Audio elements are basically sequences of digitized audio samples, while visual elements are sequences of raster frames. In either case the sequences may not be stored explicitly, but instead stored in a compressed representation, or an alternate representation from which the sequences are produced (as when audio is synthesized from a symbolic representation, such as musical notation, or video frames are rendered from animation data). Because of the temporal nature of digital video, its production and consumption often requires specialized devices capable of the real-time handling of streams of data. Until recently this equipment was expensive and not readily available. However a number of significant advances are now taking place that are greatly increasing the use of digital video. These developments include advances in high-bandwidth networks and protocols facilitating real-time transfer of digital video; improvements in storage media such as high-capacity magnetic disks and writable CDs; faster rendering rates for graphics hardware allowing real-time animation; greater availability of special-purpose audio and video processors on workstations; and better computer interfaces to both commercial and professional video products such as camcorders, VCRs, and video mixers. Another significant development is real-time compression and decompression hardware for digital video. The compressed video has data rates comparable to bus and disk bandwidths and so opens the possibility of video recording and playback from conventional secondary storage devices. In addition, an anticipated future development having broad-impact on the use of video, will be the emergence of standards for HDTV. In light of these changes, new possibilities are arising for application developers -- in particular those who aim to enhance hypertext, or hypermedia, with video capabilities. Early interactive video systems relied on analog read-only videodisc technology. This "first generation" of video-based hypermedia provided very good video quality, but suffered from limitations imposed by the videodisc. Now digital video offers a way around many of the drawbacks of the videodisc -- digital video can be edited and modified, it can be processed, and, like any other form of data, it can be stored and retrieved from conventional storage systems. This presentation will focus on implications of digital video for hypermedia. A short overview of video technology will be provided, introducing such topics as video formats, video compression, and video editing. Several low-cost platforms for running digital video applications will be described and illustrated with short videotapes. Finally we consider a number of traditional hypertext issues in the context of digital video. Approaches to linking video with other information, techniques for structuring video and increasing interactivity during playback, and new forms of composition and navigation will be presented. Many of these techniques are now being explored in prototype systems. Examples of existing prototypes will be used to illustrate the potential of digital video when used in hypermedia systems.

Bertino, Elisa, Rabitti, Fausto and Gibbs, Simon (1988): Query Processing in a Multimedia Document System. In ACM Transactions on Information Systems, 6 (1) pp. 1-41.
Query processing in a multimedia document system is described. Multimedia documents are information objects containing formatted data, text, image, graphics, and voice. The query language is based on a conceptual document model that allows the users to formulate queries on both document content and structure. The architecture of the system is outlined, with focus on the storage organization in which both optical and magnetic devices can coexist. Query processing and the different strategies evaluated by our optimization algorithm are discussed.

Gibbs, Simon and Tsichritzis, Dionysis (1983): A Data Modeling Approach for Office Information Systems. In ACM Transactions on Information Systems, 1 (4) pp. 299-319.
A data model for representing the structure and semantics of office objects is proposed. The model contains features for modeling forms, documents, and other complex objects; these features include a constraint mechanism based on triggers, templates for presenting objects in different media, and unformatted data types such as text and audio. The representation of common office objects is described. User-level commands may be translated to operations within the model.

Office information models are used to represent the operations and information structure of Office Information Systems. This paper determines requirements for these models by examining the functionality of Office Information Systems. The paper then discusses the representation of 'office objects' and their associated operations of filing, mailing and formatting. This representation is based upon concepts from the field of semantic data modelling.
