“…Thus, the fast forward surrogates used in this study are an approximation of what may be both technically possible and also useful from the human perceptual system point of view. 1 Rather than using the awkward phase, 'Nth frame fast forward', we simply call these surrogates 'fast forwards'.…”

“…There is less attention to creating user interfaces that support interactive search and browse capabilities. The Informedia project (www.informedia.cs.cmu.edu/) is perhaps the most comprehensive digital video effort that includes novel user interfaces and usability testing [1,2,24]. Their video skims are surrogates created from several kinds of features (transcripts, keyframes extracted with color and texture features, superimpositions, and other features such as face recognition).…”

“…For example, various layouts for video keyframes for gist understanding and for searching have been studied in [11,12,13,14,15]. Selecting the right keyframes for presenting the result of a user's video query has also been studied [16] and interactive playback tools that allow efficient content-browsing [17,18], interactive montages of map and timelines to visualise news video contents [19] have been evaluated. These experiments address some of the end-user's experiences with video retrieval systems, in other words, studying the constituent elements of a more complete, integrated, full multimedia retrieval system by attempting to explore and optimise the details of the best methods to use in these searching/browsing/presentation tools.…”

Collaborative video searching on a tabletop

Almost all system and application design for multimedia systems is based around a single user working in isolation to perform some task yet much of the work for which we use computers to help us, is based on working collaboratively with colleagues. Groupware systems do support user collaboration but typically this is supported through software and users still physically work in independently. Tabletop systems such as the DiamondTouch from MERL, are interface devices which support direct user collaboration on a tabletop. When a tabletop is used as the interface for a multimedia system, such as a video search system, then this kind of direct collaboration raises many questions for system design. In this paper we present a tabletop system for supporting a pair of users in a video search task and we evaluate the system not only in terms of search performance but also in terms of user-user interaction and how different user personalities within each a pair of searchers impacts search performance and user interaction. Incorporating the user into the system evaluation as we have done here reveals several interesting results and has important ramifications for the design of a multimedia search system.

“…Evolution of digital video library (DVL) enables people to search and access rich video content. The techniques involved in composing videos into vast DVL for content-based retrieval are provided in the literature [1][2][3]. The development of DVL includes video information extraction [4].…”

We developed technologies for transmitting video contents over wireless platforms, and encapsulated these video delivery and presentation technologies into a client system for accessing a multimodal digital video library. The mobile access system, iVIEW client, provides a user interface that meets the challenge of rich multi-modal information presentation on wireless hand-held devices. An XML schema is employed to organize the multi-modal metadata for better data interoperability. Furthermore, we investigated a context awareness mechanism complementary to the XML schema to facilitate scalable degradation under restricted resources in wireless application environment. This paper presents the design, implementation, and evaluation of the iVIEW system and its associated technologies for video information management and delivery on pervasive devices over wireless networks.
