“…The Open Video Project (www.open-video.org) currently has more than 1800 video segments with a variety of automatically and manually generated metadata elements. The repository is used as a testbed for creating and testing highly interactive user interfaces for digital video (See [1] for an overview of the project and [2] for details regarding one of the previous user studies). These interfaces are crucially dependent on surrogates (metadata that 'stands for' the full object) that provide context and clarity during the retrieval process.…”

“…During a saccadic interval, the eye doesn't collect information but is simply moving from one place to another [5]. A point of fixation is the period between saccades, typically ranging from 200-600ms 1 , in which a stable visual point is held and information can be viewed [4,5,6]. An analysis of saccades and fixations can capture the wide range of visual perceptions and, presumably, cognitive processes people undergo when accessing information from a computer generated visual display [4,7].…”

One important user-oriented facet of digital video retrieval research involves how to abstract and display digital video surrogates. This study reports on an investigation of digital video results pages that use textual and visual surrogates. Twelve subjects selected relevant video records from results lists containing titles, descriptions, and three keyframes for ten different search tasks. All subjects were eye-tracked to determine where, when, and how long they looked at text and image surrogates. Participants looked at and fixated on titles and descriptions statistically reliably more than on the images. Most people used the text as an anchor from which to make judgments about the search results and the images as confirmatory evidence for their selections. No differences were found whether the layout presented text or images in left to right order.

“…Wildemuth et al (2002) argued that textual video surrogates can facilitate the process of determining relevance, and non-textual video surrogates can effectively augment textual surrogates. Hughes et al (2003) suggested that textual surrogates appear to transmit information regarding the contents of the video, while non-textual surrogates appear to transmit information regarding what the video was like.…”

Design and evaluation of a key‐frame arrangement framework for video storyboard surrogates

This study examines the design and evaluation of a key-frame arrangement framework for video storyboard surrogates. First, we constructed an arrangement model of keyframes for a storyboard based on the Preserved Context Indexing System (PRECIS) and a narrative theory. Second, we evaluated the model using six sample videos and 26 participants, and then analyzed the results using a t-test and repeated-measure MANOVA. The results revealed that structurally arranged storyboards (STR) following the arrangement framework are not effective for either summarizing or indexing videos than sequentially arranged storyboards (SEQ) and that the repetition of viewing storyboards is effective for summarizing (not indexing) videos. The order of viewing two storyboards, regarding which of STR or SEQ comes first, is also crucial for improving subjects' summarizing ability. When subjects are viewing STR after SEQ, they summarize videos more effectively than viewing SEQ after STR.

“…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.…”

Collaborative video searching on a tabletop

et al. 2006

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.
