摘要:
Recorded video is accessed from printed notes or summaries derived from the video. Summaries may be created automatically by analyzing the recorded video, and annotations are made by a user on a device for note-taking with digital ink and video. The notes and/or summaries are printed along with data glyphs that provide time based indexes or offsets into the recorded video. The indexes or offsets are retrieved by scanning the glyph on the printout. The glyph information can be embedded in the printouts in many ways. One method is to associate block glyphs with annotations or images on the printed pages. Another method is to provide an address carpet in an annotated timeline. Yet another method is to provide a two-dimensional address carpet with X-Y position mapped to time which can be used to provide selected access to the video. The accessed video may be played back on the note-taking device on a pen computer, or on a summary interface on a Web browser-type device.

Described is a system that characterizes segments of a document with one or more keyphrases and then uses the keyphrases to help users find interesting parts of a document. The keyphrases are displayed with information about the location of the phrase in the document and are used as pointers to quickly move to from an overview to a section of potential interest.

A system that represents a video sequence comprising plurality of video clips as a number of images. The plurality of video clips is represented as a reduced representation of video images. A video clip is represented as a keyframe, wherein multiple keyframes may then be arranged according to chronological order. All or only a representative portion of the video clips can be represented as keyframes. The size of the keyframe may be configured to represent the length or importance of the video clip. The keyframe may depict an entire frame of a video clip, or a region of meaningful information within a frame of a video clip. Multiple keyframes may be arranged in a two dimensional array, in an S-shaped curve, or some other pattern. The keyframes may depict motion of an object occurring over time in the video clip by configuring groups of pixels in the key frame. Configuring groups of pixels may include colorizing pixel groups and depicting pixel groups at a semi-transparent level according to the number of frames between the keyframe and the frame containing the object in motion.

Systems and methods for creating and updating interactive 3D visualizations of media indices wherein separate indices are located above and below a ground plane. The indices are organized in table structure defined by two axes and provide links to the media that is indexed. Various visual characteristics of the indices communicate characteristics of the media that is indexed as well as various user defined or group defined information relating to the indexed media.

A method for exchanging information in a shared interactive environment, comprising selecting a first physical device in a first live video image wherein the first physical device has information associated with it, causing the information to be transferred to a second physical device in a second live video image wherein the transfer is brought about by manipulating a visual representation of the information, wherein the manipulation includes interacting with the first live video image and the second live video image, wherein the first physical device and the second physical device are part of the shared interactive environment, and wherein the first physical device and the second physical device are not the same.
摘要:
A method and apparatus for providing multi-resolution video to multiple users under hybrid human and automatic control. Initial environment and close-up images are captured using a first camera and a PTZ camera. The initial images are then stored in memory. Current environment and close-up images are captured and the an estimated difference between the initial and current images and the true image is determined. The estimated differences are weighted and compared and the stored images are updated. A close-up image is then provided to each user of the system. The close-up camera is then directed to a portion of the environment image having high distortion, and current environment and close-up images are captured again.

A system features a data input scheme in which the nature of the entered data is irrelevant until the requirement made to perform a function with respect to that data. It is only when it becomes necessary to perform a function with respect to the data that the determination of the nature of the data become important. The desired function, which may include editing, rearranging, moving, etc., then results in a determination of the nature of the data in order to enable implementation of that specific function. The nature of the data can be determined to be in the form of a list, table, or diagram. To this end, a screen oriented display processing system is provided for the entry of informational data including a display means, a data entry means for entering informational data on the display means, a gesture entering means for entering handwritten gestural data on the display, the gestural data representing a gesture associated with at least a portion of the informational data on the display, an assignment means responsive to the entry of the gesture for assigning a function representative of the gesture to the portion of the informational data, and an implementing means responsive to the assignment means for implementing the function on the said portion of the informational data.

Domain objects for use in a freeform graphics system. Domain objects are context specific representations of information that are used in a freeform graphics system. Domain objects are represented in a freeform graphics system by a graphic object (icon) representing an instance of the domain object. The icon representing a domain object may be manipulated like any other graphic object. Domain objects are defined by a domain object class which define attributes, a set of action rules and layouts. The attributes describe the information or data associated with the domain object. The set of action rules map user actions and system events to operations that may be performed on the domain object. The layouts define how domain object information is displayed as an icon. The attributes may have computed values. An attribute have it's value computed based on the value(s) other attribute(s) or based on the spatial positioning of the icon representing the data object on a work surface.

An electronic multimedia document system provides temporal icons that provide indices into a recording of a meeting or presentation. The temporal icons index the times of occurrence of events and beginning times, ending times, and time spans of timestreams. The temporal icons provide complete playback control of the document through a gestural interface.

Meeting support objects for supporting meeting objectives for use in a freeform graphics system. Meeting support objects are representations of dynamic information that is used to support various common activities performed in meetings, such as decision making, assigning action items, agenda tracking, etc. Meeting support objects are defined by a domain object class. The domain object class defines attributes, a set of action rules and layouts. The attributes describe the information or data associated with the meeting support object. Further, the underlying attribute values represented by the icon may change, based on predefined spatial parameters, as the result of user actions performed on the icon (e.g. via a gesture) or upon the occurrence of a system event. The set of action rules map user actions and system events to operations that may be performed on the meeting support object. The layouts define how meeting support object information is displayed as an icon.
