Computer user interface for audio and/or video auto-summarization

Abstract

A relativity controller is a scroll bar / window combination that provides a way to see data in relation to both the context of its wholeness and the salience of its contents. To accomplish this, the linear density or other appearance of the scroll bar (acting as a ruler or scale) varies with the density of the document salience (as indicated by different kinds of annotations or marks). It also provides a way to zoom between perspectives. This is usable on many different data types: including sound, video, graphics, calendars and word processors.

Description

[0001]This invention relates to a computer system, and in particular to computer tools to improve user perspectives and enhance navigation or browsing of information sources stored in or available via the computer.BACKGROUND OF INVENTION[0002]As computer accessing of large quantities of information increases, the ability of users to navigate large information spaces and to maintain visualization or personal perspectives thereof decreases [1] (bracketed numbers reference publications identified in Appendix A).[0003]The heed for this type of control has been expressed most recently by Furnas [2], Mills [3], Degen [4], and Chimera [5].[0004]Furnas' solution to the problem of understanding the limited information available in a window of large information structures is to provide in the window the detailed region to be considered in the context of important preceding or succeeding parts of the large structure. For example, to edit lines in the middle of a program, the window would also ...

Benefits of technology

[0010]Another object of the invention is a computerized system and method to enable users better to navigate or visualize large information spaces.

[0011]In accordance with one aspect of the present invention, means are provided to enable a user to visibly mark points or segments of displayed information, which will enable the user to quickly navigate to the marked displays.

[0013]In accordance with a further aspect of the present invention, a computerized system provides the user with means to shrink less important or less significant portions of the information displayed, with the result of magnifying the portions that the user deems significant. In accordance with this aspect, the invention can be viewed as a user-friendly relativity controller tool that enables users to specify what is important to them, and modify the portion of their perceptual space that that information takes up, in a fisheye variant.

[0015]In accordance with still other aspects of the invention, the relativity controller of the invention is implemented by simply pointing to the screen and actuating a control device. In a preferred embodiment, a mouse button, is pressed to mark the beginning and end of segments of the information to be marked. A further feature is that multiple segments can be marked in this manner. Thus, the relativity controller of the invention not only allows users to mark the scope of one or more salient segments, but also will cause the display to simultaneously shrink the non-marked portions and in effect zoom into the multiple-marked segments in a single step. The result is a non-linear display of the available information. As a further feature, simultaneously with selective zooming of the information, the display of the scroll bar is correspondingly modified to show in the context of the total information the marked and non-marked portions of the displayed information.

[0016]The major benefits is to allow users to quickly navigate through a large information space and to control the salience of the displayed information in the context of the full display while conserving display area, sometime called desktop real estate. Moreover, maintaining a single window for the data and giving users the ability to visually navigate across the whole data via the scroll bar together with the ability to select the salient segments as well as the level of zoom, all in a single step, greatly enhances the ability of the user to cope intelligently and rapidly with large information structures containing large numbers of objects.

Problems solved by technology

Chimera, on the other hand, maintained a full display within the window but was unable to provide a zooming feature or expanded segment view of a text listing.

But Furnas doesn't disclose how a user can select which segments to display, or the means to magnify certain segments, or the means to control the degree of magnification, nor does Furnas provided a scroll bar or its equivalent as a convenient interface for the user to manipulate the display.
