The systems and methods of this invention use an index and digital audio and/or video recordings of an activity to provide access to recently recorded material. For example, users initiate audio and/or video recordings. An index, e.g., an agenda, outlines the structure of the to be recorded event. The user selects an index item as an activity that corresponds to an index item is recorded. The recordings are then associated with the index. The user can then randomly access the recordings for playback, editing or further recording. The systems and methods of this invention additionally provide the means for correlating events and the corresponding index items with the recordings.

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 spatial separations between clusters of objects on the electronic work surface are analyzed to automatically generate borders, which may be used in at least two manners. The borders may become explicit editable borders within an output image. Alternatively, the borders created may be implicit ephemeral borders. According to an aspect, a method uses the sufficient stability grouping technique to determine grouping of elements in the input image array into the text lines in the output text lines array. According to another aspect, a method uses the sufficient stability grouping technique to determine the amount of vertical expansion to apply to each text line so as to create text regions in the output array which correspond to the text lines in the input text lines array. According to yet another aspect, a method takes the text regions array as input and extracts enclosure borders from the text regions. The method according to this aspect applies distance thresholding and edge labeling based upon the contents of the text lines array. According to still another aspect, a method extracts structured borders from the text regions array. The method according to this aspect applies two-dimensional projection operations based upon the contents of the text lines array. According to yet still another aspect, a method extracts freeform linear borders from the text regions array. The freeform linear borders result from a Voronoi tesselation performed upon the contents of text regions array.

A system for controlling the playback of a recorded session utilizing a window acting as a player for playing back a timestream for a shared representation media, such as an electronic whiteboard. Timestream and event information for the session is captured by one or more recording devices. Playback of a session is performed under the control of a session access device which utilizes event information to create a user interface for controlling session replay. The user interface includes the window for playing back the timestream of a shared representation media. Each graphical object in the window is associated with one or more events (e.g. a creation event, an editing event, a move event or a deletion event). Selection of a graphical object enables playback time to be moved to the time for one of the associated events. Selection may also be made on an area of the window. This will enable the user to view all events related to graphical objects in the selected area (as some graphical objects may be erased or moved).

An enhanced information collage that combines a computational system with a physical information collage to preserve the advantages of conventional information collages while alleviating many problems associated with such collages. A physical information collage (e.g. a pin board with spatially differentiated pin mounted task cards, each card having a detectable identity tag) can be made part of a computational system by sensing the identity, position, and contents of the collage component artifacts. In effect, each collage component has its content and position stored in a database, with movement of a particular component resulting in update of the database to record the new position of that component. Further provided are Operator Icon components which may be used to provide digital services, such as combining, erasing, saving, or transferring, to other collage components.
