An apparatus and method for animating editing changes on a display device is provided. The invention is designed to operate preferably with a graphical editing system that permits both handwritten and typewritten data entry. Both the primary changes made by the user and the contextual changes resulting from the primary changes are animated at a visually apparent rate in multiple steps to permit a user and other viewers of the display device to understand the effects of an editing change on surrounding objects. The number of steps in which the changes are animated depends on the number of changes which must be made and the operation performed.

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.

A graphical editing system which allows a user to modify a selection gesture without having to redraw the entire gesture. The system defines a selection with an enclosure that is treated as a graphical object that can be contorted in a style consistent with the specific application. The enclosure can be altered, i.e., reshaped by a set of gestures which allow the user to expand or reduce the size of the enclosure. These alteration gestures activate specified points or portions of the enclosure to control its shape. If a selection enclosure is drawn, it can be altered to include or exclude additional data by drawing a line segment that is detected by its location relative to the selection enclosure as an alteration gesture to reshape the existing enclosure to include the line segment.

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 creating and manipulating groups of graphic objects using enclosures. A persistent graphic object, such as a closed loop is drawn around a set of graphic objects as an enclosure. When the enclosure is selected the enclosure and the set of graphic objects within are grouped. Besides moving graphic objects into and out of the enclosure, the contents of a group can then be modified by 1) graphically altering the enclosure loop to include or remove graphic objects, 2) fusing groups by moving one of them so that their enclosure loops overlap (i.e., they "fuse" into one), 3) fusing groups through gestures which "touch" enclosure loops of the groups to be fused or 4) splitting the group into multiple groups through a splitting gesture.

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.

A method and apparatus for representing a group of graphic objects so as to maximize usage of a display area on a computer controlled graphics display system. The present invention provides a means for "collapsing" a group of graphic objects so that the group is represented by a container icon. The container icon occupies a smaller amount of display area than the group of objects. The group is recallable (i.e. expanded) by "tapping" on the container icon. Alternatively, the group may be located on a separate accessible area of the display space. The container icon is itself a graphical object and can be moved, copied or deleted. Any change of attributes, e.g. color, of the graphical object causes a corresponding change to the group of graphic objects.
