Interactive, dynamic video browsing with the zoomslider interface

06 Jul 2005-pp 558-561
TL;DR: The ZoomSlider circumvents common problems of existing video browsing approaches, such as their lack of scalability to large document sizes and unpleasant because jerky visual feedback, and provides the power and flexibility needed for highly interactive tasks.
Abstract: We present the ZoomSlider, a new interface for skimming and browsing video content in a flexible and interactive way. It circumvents common problems of existing video browsing approaches, such as their lack of scalability to large document sizes and unpleasant because jerky visual feedback. With the ZoomSlider a user can visually skim through video files at different granularity levels thus providing the power and flexibility needed for highly interactive tasks. First usability tests are presented in order to prove the feasibility of the overall concept.

TL;DR: A comprehensive review of the state of the art in video browsing and retrieval systems, with special emphasis on interfaces and applications, which classify them into three groups: applications that use video-player-like interaction, video retrieval applications, and browsing solutions based on video surrogates.
Abstract: We present a comprehensive review of the state of the art in video browsing and retrieval systems, with special emphasis on interfaces and applications. There has been a significant increase in activity (e.g., storage, retrieval, and sharing) employing video data in the past decade, both for personal and professional use. The ever-growing amount of video content available for human consumption and the inherent characteristics of video data-which, if presented in its raw format, is rather unwieldy and costly-have become driving forces for the development of more effective solutions to present video contents and allow rich user interaction. As a result, there are many contemporary research efforts toward developing better video browsing solutions, which we summarize. We review more than 40 different video browsing and retrieval interfaces and classify them into three groups: applications that use video-player-like interaction, video retrieval applications, and browsing solutions based on video surrogates. For each category, we present a summary of existing work, highlight the technical aspects of each solution, and compare them against each other.

TL;DR: In this paper, the authors present an information display device for easily changing a scrolling speed and a display mode. The information display devices receive an instruction for displaying a plurality of contents, via a move operation on a two-dimensional plane defined by first and second axes.
Abstract: The present invention aims to provide an information display device for easily changing a scrolling speed and a display mode. The information display device receives an instruction for displaying a plurality of contents, via a move operation on a two-dimensional plane defined by first and second axes; determines a moving speed for moving the contents, based on a motion component of the move operation along the first axis, and determines a display mode for displaying the contents, based on a motion component of the move operation along the second axis; and displays the contents in the display mode on a screen, by scrolling through the contents at the moving speed.

TL;DR: A new interface for the pen-based navigation of videos on PDAs and multimedia cellphones, called the MobileZoomSlider, enables users to intuitively skim a video along the timeline on different granularity levels, thus taking optimum advantage of the limited screen space.
Abstract: Today, videos can be replayed on modern handheld devices, such as multimedia cellphones and personal digital assistants (PDAs), due to significant improvements in their processing power. However, screen size remains a limiting resource making it hard, if not impossible to adapt common approaches for video browsing to such mobile devices. In this paper we propose a new interface for the pen-based navigation of videos on PDAs and multimedia cellphones. Our solution - called the MobileZoomSlider - enables users to intuitively skim a video along the timeline on different granularity levels. In addition, it allows for continuous manipulation of replay speed for browsing purposes. Both interaction concepts are seamlessly integrated into the overall interface, thus taking optimum advantage of the limited screen space. Our claims are verified with a first evaluation which proves the suitability of the overall concept.

TL;DR: A first user study has shown that the proposed approach can significantly outperform standard soft video players - the state-of-the art "poor man's" video browsing tool.
Abstract: A new approach for interactive video browsing is described. The novelty of the proposed approach is the flexible concept of interactive navigation summaries. Similar to time sliders, commonly used with standard soft video players, navigation summaries allow random access to a video. In addition, they also provide abstract visualizations of the content at a user-defined level of detail and, thus, quickly communicate content characteristics to the user. Navigation summaries can provide visual information about both low-level features but even high-level features. The concept fully integrates the user, who knows best which navigation summary at which level of detail could be most beneficial for his/her current video browsing task, and provide him/her a flexible set of navigation means. A first user study has shown that our approach can significantly outperform standard soft video players - the state-of-the art "poor man's" video browsing tool.

TL;DR: The virtPresenter lecture recording system is presented that tackles navigation in web lectures with a hypermedia navigation concept that is improved with interactive content overviews and addresses didactic scenarios for web lectures and issues related to the workflow of recording lectures.
Abstract: Lecture recordings can be a powerful addition to traditional lectures and they can even serve as a main content source in a number of didactic scenarios. If users can quickly locate relevant passages in a recording, the recording combines the ease of search that comes with electronic text based media with the authenticity and wealth of information that is delivered in a live lecture. Locating relevant passages in a time based media such as a recorded lecture is, however, not as easy as searching an electronic text document. This article presents the virtPresenter lecture recording system that tackles navigation in web lectures with a hypermedia navigation concept that is improved with interactive content overviews. Apart from navigation in web lectures the article also addresses didactic scenarios for web lectures and issues related to the workflow of recording lectures.

TL;DR: A transient position+velocity widget that allows users not only to move around a point of interest on a video, but also to rewind or fast forward at a controlled variable speed is presented.
Abstract: We explore a variety of interaction and visualization techniques for fluid navigation, segmentation, linking, and annotation of digital videos. These techniques are developed within a concept prototype called LEAN that is designed for use with pressure-sensitive digitizer tablets. These techniques include a transient position+velocity widget that allows users not only to move around a point of interest on a video, but also to rewind or fast forward at a controlled variable speed. We also present a new variation of fish-eye views called twist-lens, and incorporate this into a position control slider designed for the effective navigation and viewing of large sequences of video frames. We also explore a new style of widgets that exploit the use of the pen's pressure-sensing capability, increasing the input vocabulary available to the user. Finally, we elaborate on how annotations referring to objects that are temporal in nature, such as video, may be thought of as links, and fluidly constructed, visualized and navigated.

TL;DR: A sub-pixel-pitch dragging tool, popup vernier, plus a methodology to transfer smoothly into ‘vernier mode’ during dragging are proposed and verified with a proposed evaluation measure that captures the smoothness of transition from standard mode to verniers mode, based on the Fitts’ law.
Abstract: Dragging is one of the most useful and popular techniques in direct manipulation graphical user interfaces. However, dragging has inherent restrictions caused by pixel resolution of a display. Although in some situations the restriction could be negligible, certain kinds of applications, e.g., real world applications where the range of adjustable parameters vastly exceed the screen resolution, require sub-pixel-pitch dragging. We propose a sub-pixel-pitch dragging tool, popup vernier, plus a methodology to transfer smoothly into ‘vernier mode’ during dragging. A popup vernier consists of locally zoomed grids and vernier scales displayed around them. Verniers provide intuitive manipulation and feedback of fine grain dragging, in that pixel-pitch movements of the grids represent sub-pixel-pitch movements of a dragged object, and the vernier scales show the object’s position at a sub-pixel accuracy. The effectiveness of our technique is verified with a proposed evaluation measure that captures the smoothness of transition from standard mode to vernier mode, based on the Fitts’ law.
