An electronic market for trading of securities includes a plurality of client stations for entering quotes for securities and a server process that receives quotes from the clients, aggregates the quotes and causes a total of all aggregated quotes to be displayed for a plurality of price levels on the client systems. The market uses a graphical user that depicts aggregated quotes in an aggregate window a plurality of price levels of a product traded in the market. The market also includes processes to handle lock/cross market conditions, match-off of order flow and provides a central quote/order collector that interfaces to disparate order delivery systems to minimize dual liability of market makers.

A graphical input and display system having a user interface for selecting and creating image object elements includes input devices permitting a user to manipulate elements of electronic images. A processor, connected to the system, receives requests for various image object selection operations and also accesses a memory structure. The system memory structure includes a user interaction module, which allows a user to select image objects, an image object selection module for interpreting imprecise image object selection paths, and data memory.

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.

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.

Conveying apparatuses, indication assemblies, methods of indicating operation of a conveying apparatus, and methods of operating a conveying apparatus are provided. According to one aspect, a conveying apparatus includes a frame; a bed configured to convey material in a direction; a drive device configured to impart movement to the bed; and an indication assembly configured to indicate operation of the conveying apparatus in an operational state. Another aspect provides a method of indicating operation of a conveying apparatus comprising: providing a conveying apparatus including a bed; supporting the bed using a frame; imparting movement to the bed to induce movement of material within the bed; and indicating operation of the conveying apparatus in an operational state.

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.

A user-interactive method for use in a processor-controlled machine provides a user with the capability to establish associations among image segments in a data structure that indicate visually-displayed but otherwise not recognized or interpreted information, for the purpose of retrieving the unrecognized data from the data structure without performing a recognition operation. A user selects and designates a visually recognizable, but computationally unrecognized, displayed image segment as a coherent display object, called a key object, to function as an indexing mechanism. The user then associates the key object with data objects, which may also be computationally unrecognized, that are stored in a target data structure. The key object can be used as an access mechanism to retrieve the target data without recognition of either the key object or the target data. For this reason the method is particularly useful in systems that provide for a stylus- or pen-based computing interface, since it provides a flexible and powerful information indexing capability while avoiding the need to perform generally error prone recognition operations on handwritten or other graphical symbols. A key object is assigned a unique identifier that is computationally distinguishable from other key object identifiers, and a key object-to-data association is established between the unique identifier and the target display object. A well-designed graphical user interface permits key objects to be easily created, associated with displayed information, and reused.
摘要:
A computer-controlled graphics display system providing improved means for selecting objects for joint action. The invention helps the user of a graphical user interface more easily select a group of objects that are meaningfully related to each other. Objects are usually created serially in time by a user, but they are typically selected by spatial grouping in graphical user interfaces. The invention shows that such a spatial grouping can be refined by considering the temporal grouping of objects. Algorithms are proposed which combine both spatial and temporal grouping to produce the most appropriate grouping of objects, i.e., groupings that most likely conform to the user's intentions.
