A system provides a user interface for maximizing an amount of information presented on a computer generated display. The system includes a user interface management system (UMIS) that works with an operating system that manages the computer resources including a display screen and a user input device for tracking position. The UMIS is responsive to the user input device to effect changes in the computer generated display. The UMIS communicates with an application program using the user interface. The user interface has at least a first layer for displaying a primary dynamic image and a second layer for displaying a secondary dynamic image. The second layer has a plurality of display modes including a first mode corresponding to at least a portion of the second layer assuming an invisible state in the computer generated display. Selection of the display modes is effected by signals received from the user input device. Both the first and second layers are updated regardless of the mode of the second layer. The user interface is particularly applicable to air traffic control where the first layer is used for displaying a map plotting aircraft locations and the second layer is used for displaying various data concerning the aircraft, both being updated continuously.
User Interface and Method for Maximizing the Information Presented on a Screen This invention relates generally to methods for displaying graphical information on a computer system, and more particularly, the present invention relates to a computer controlled display system for organizing the display of a high volume of information and a user interface to allow the operator to readily view all sets of information.
A windowing environment is system software that manages interactions between a user and an application program executing on a computer through a graphical display monitor. Typically, the graphical display is arranged to resemble an electronic "desktop", and each sheet of information on the "desktop" is displayed in a rectangular region of the screen called a "window". The windows on the "desktop" can be organized in a variety of different ways. They can be tiled so the contents of each window are totally visible to the operator, they can be overlapped so that the contents of a window partially overlays another window, or they can be stacked so that one window completely overlays another window. The windows on the desktop can be used to contain any object, including simple objects such as menus, forms and tables and complex objects such as spreadsheets and radar displays for air traffic control.
In a typical window-based Graphical User Interface (GUn system (such as Microsoft Windows~ or OSF Motif), a variety of techniques are provided to the operator to manage the windows on the display. The windows can be made larger or smaller, they can be expanded to be the full screen size, they can be moved to a different position on the screen, or they can be reduced to an icon. An icon is a small, visually distinct display object which represents the window.
In a traditional office application, the windows are used to represent static information such as documents and spreadsheets. The content of a window changes only when a change is effected by the operator. However, there is a class of applications _2_ where the information in the windows changes dynamically independently of operator intervention. For example, in an Air Traffic Control display, one window may contain a geographic view of the airspace in which aircraft are plotted on the display according to their current position based on radar reports. Another window may have a dynamically changing table summarizing details about each aircraft including information such as current speed and altitude, which is updated based on radar reports.
One of the problems associated with window based graphical user interfaces is the necessity of carefully managing the display screen space. In many complex applications there is a great deal of information which must be displayed to the operator in multiple windows. However, with multiple windows, there is often not enough screen space (screen "real estate") to concurrently view all the important information displayed in various windows. For example, in Air Traffic Control, the focus of the radar operator is on the main situation display window where the operator is tracking the movement of aircraft through the radar plots displayed in the window. The operator also needs to regularly be able to view additional information about the aircraft, weather conditions, etc., as displayed in other windows. However, at the same time, the operator needs to maintain full awareness of the main situation window which reflects the position of all aircraft. The ability to maintain a great number of windows on the screen without obscuring the main window of interest is desired. In these situations, it is too cumbersome and time consuming to use standard window manipulation techniques such as resizing or moving windows.
The present invention provides a method and user interface technique that allows the operator to maintain a large number of windows all containing information necessary for the operator to perform his task, while at the same time not obscuring other windows which are essential to perform the task. This approach significantly increases operator productivity and also increases safety when employed in safety critical applications since it permits the operator to maintain maximum awareness of the main safety critical situation window, while still providing immediate access to the other information necessary for the operator to perform his task The invention operates in a standard environment of computer workstation with a graphical display. Information is displayed in "windows" on the graphical display, and the operator interacts with the display with standard input devices such as a keyboard and a mouse. This invention may be embodied in an application program that executes on the workstation or any other type of program, including the Operating System which controls the workstation.
This invention consists of a user interface which provides the operator with a rapid means to expose and hide information in invisible windows. When the information in windows is hidden, the "invisible" windows can be totally invisible (i.e., there is no visual indication of their location), the windows may have a title bar that is visible, the windows may have a window border that is visible, or the windows may have a title bar and window border that is visible. These latter states provide the operator with a visual clue as to the location of the hidden window. In all these cases, the contents of the invisible window are not displayed and the background window is fully visible through the invisible window.
. The user is provided the ability to designate each invisible window as "normal", "timed", "locked", or "timed icon". The user is also able to reduce an invisible window to an icon at any time. When an invisible window is reduced to an icon no window operations can be performed on the window until the icon is raised back into an invisible window.
When in "normal" mode, the contents of the window are exposed when the cursor moves into the area of window. The window contents can be exposed either by allowing the window to be displayed on an opaque background, which enhances ,_ _4_ legibility of the window contents, or on a transparent background, which enables the contents of the background windows to be visible underneath the invisible window. The window contents are hidden again by simply moving the cursor away from the window.
In "timed" mode, the contents of the window are exposed in the manner described above for a specified period of time, at which time the window automatically returns to its invisible state.
In "locked" mode, the contents of the window are exposed in the manner described above until another mode is selected for the window.
In 'timed icon" mode, the contents of the window are exposed in the manner described above for a specified period of time, at which time the window is automatically reduced to an icon.
The present invention will be better understood from the following description with reference to the drawings, where:

Figure 1 depicts a typical computer system suitable for supporting the present invention. Figure 1 is but one of many computer configurations that can support the present invention. Figure 1 shows a computer system consisting of an output device 1 (display monitor), input devices (mouse 5 and keyboard 6) and a system chassis 3. Other configurations might include flat screen displays, X-terminals, trackballs, touch screens and other devices.
The system chassis 3 contains components such as the Central Processing Unit (CPU), memory, hard disk storage, power supply, local area network , parallel printer I/O, serial I/O, and video generation hardware. The system chassis 3 may contain optional items such as CDROMs, tape drives, sound generation facilities and others.
The present invention provides a means to efficiently manage screen space when there are conflicting demands of high priority information in background windows which occupy large portions of the display surface 2 and numerous information windows overlaying it. The present invention can be implemented at four different levels in a computer system. It can be applied in the graphics generation hardware, the operating system graphics subsystem software (X Windows, OpenGL ~, Microsoft Windows ~, Apple MacO/S ~, etc.), a User Interface Management System (UIMS), or in application software. The discussion below deals mostly with implementation of the present invention in a UIMS and associated application programs. A UIMS is a layer of software which manages all display and user device input activities for a specific application. The discussion is divided into three parts: Part 1 describes the invention as manipulated by the operator; Part 2 describes the invention in terms of the software algorithms which describe its operation; Part 3 describes the features of the UIMS to support the event 1 S capture and drawing techniques necessary.
Figure 2 depicts a typical application display presentation where the present invention would greatly enhance operator usability and operator access to important data.
In this view normal windowing techniques are in force. The high importance background data 8 (radar return information in this case) is being obscured by multiple overlapping user interface windows 7.
Figure 3 depicts the same application with the invisible window feature operating.
Notice now that the overlapping windows 10 no longer obscure the background radar data 9. The overlapping windows' title bars and window frames 11 are still visible giving ' _7-the user visible cues as to where the windows will be when opaque. The view of the background radar in Figure 3 is vastly improved over that in Figure 2.
The technique which the operator uses to toggle between opaque and invisible is as simple as moving the cursor 12 over the invisible window which the operator wishes S to view. In Figure 3 the cursor 12 is over the background data 9, not an overlapping window 10. This causes all overlapping windows 10 to be invisible.
Figure 4 demonstrates the system's reaction to moving the cursor over an invisible window. Notice that the cursor 16 is now over the table titled Category Select 15. This table is now opaque while the others 14 remain invisible. The background data 13 is covered by tables 15 but remains unaffected by tables 14.
Further control of the invisible effect is afforded the operator through a button in the title bar of the tables 17. Activating this button causes the display mode menu 18 to be activated. Figure 5 depicts the display mode menu. The menu consists of four buttons 19, 20, 21, 22. Each button has a graphical icon and textual label.
When a button is selected its icon is placed in the display mode menu 18 as seen in buttons 17 of Figure 4. Each window can be placed in a separate mode.
_g_ Button 22 is used to activate the Timed-Icon display mode. In this mode all overlapping windows are invisible by default. A window becomes opaque when the cursor is placed within its extent. When the cursor leaves its extent a two step time-out process begins. After the first time-out, the window goes invisible and the second time-out begins. After the second time-out, the window automatically iconifies.
Window 23 in Figure 4 illustrates an iconified window. These time-outs are configurable but are typically ten seconds. The time-outs are terminated if the cursor is placed over the window before the operation completes.
The activation ofanyoftheNormal, Locked, Timed, or Timed-Icon buttons causes the mode data field on the associated window to be updated to the appropriate mode.
Figure 6 illustrates the general software architecture of the invisible window system. A window has three pieces of data associated with it for the purposes of this discussion. Each window has a unique identity stored in window id. Each window can operate in one of four modes: Normal, Locked, Timed, or Timed-Icon. Finally, each window can be in one of three states: invisible, opaque or iconified.
The user moves the mouse 26 pointer from an opaque state window to the background which generates a hardware event 32. The operating system 25 services the hardware mouse event 32 and passes a message 29 to the UINIS 24. The UINIS 24 maintains the extent of all objects it manages. It traverses this list examining each window's extent to determine if the cursor now lies within the same window as the previous event. If the LTIMS 24 does not find a match, the UINIS checks if the cursor was previously on an opaque window. If true, the UINIS 24 next determines if that window has been designated as a potentially invisible window. If the window is designated as potentially invisible the application defined invisible state 30 is applied to the window by the AIMS 24. The user may specify the invisible state 30 to the UIMS such that the entire window becomes invisible or just user specified portions of it become invisible.
The application of this state causes the UIMS 24 to redraw the window on the display 28 according to the invisible state specifications.
The user moves the mouse 26 pointer over an invisible window which generates a hardware event 32. The operating system 25 services the hardware mouse event 32 and passes a message 29 to the UIM 24. The UIMS 24 maintains the extent of all objects it manages. It traverses this list examining each window's extent to determine if the cursor now lies within that extent. If the UIMS 24 finds a match, it next determines if that window has been designated as an invisible window. If the window is designated as potentially opaque the application defined normal state 30 is applied from the window by the UIMS 24. The application of this state causes the UIMS 24 to redraw the window on the display 28 according to the normal state specifications. The UIMS 24 notes the fact that the cursor is over a particular window which is now opaque.
Figures 7 through 10 depict flow chart views of the logic within the UIMS 24.
When the lower levels of the UIMS (see part 3) detect a motion event on a window an algorithm depicted in Figure 7 is initiated 33. The algorithm compare 34 the window id in the event message with the stored previous window id. If the windows are the same the algorithm terminates 44.
If the current and previous window ids do not match, the mode of the window is tested 35. If the window is in normal mode then apply the invisible state to the window 36. If the window is not in normal state then test to see if it is in Timed mode 37. If the window is in Timed mode then schedule a "timed invisible" time out event to start 39.
If the window is not in Timed mode then test to see if it is in Timed-Icon mode 38. If the window is in Timed-Icon mode then schedule a "timed invisible" time out event to start 39. Regardless of which mode the current window is in the state of the previous window is now tested 40. If the current window is invisible, remove the invisible state 41 to make the window opaque. Next, store the current window id as the previous window id 42 and remove any time outs that may be pending on the window from previous cursor movement 43. This algorithm now terminates and regular processing continues.
Figure 8 depicts the algorithm used to process "timed invisible" time out events.
The algorithm is initiated when a time out of type "timed invisible" is received 45. The window state is set to invisible and the window is checked to see if it is in Timed-Icon mode 48. If it is a new time out of type "timed icon" is initiated 47. The algorithm now terminates 49.
Figure 9 depicts the algorithm used to process "timed icon" time out events.
The algorithm is initiated when a time out of type "timed icon" is received 50.
The window state is set to iconified 51. The algorithm now terminates 52.
1 s PART 3 To support the above described behavior the invention embodies the capabilities described below.
The UIMS of Figure 6 contains application-oriented objects, hierarchical InterMAPhics display lists, and one or more rasterized images. Representations of the obj ects are maintained in the display lists by the presentation manager, and the rasterized images are created from the display lists by the renderer. This is shown in detail in Figure 10.
' -11-~ a number of representations each defined by an overall display layer and position, individually layered and positioned object components, and symbolic references to UIMS graphical constructs for each component ~ a number of logical states defined by UIMS keys linked to representation changes ~ a number of behaviors defined by UIMS actions linked to symbolic object events.
Specification of object properties is via UIMS configuration data, typically loaded at system startup.
The presentation manager maintains hierarchical display lists according to the current properties of the application-oriented obj ects. The presentation manager provides the following functionality:
~ inserts, modifies, and deletes graphical data in the display lists to reflect the representation properties of the application-oriented objects ~ maintains a hierarchical ordering among and within the display lists to reflect the layering properties of the application-oriented objects ~ maintains a mapping from all graphical data in the display lists to the application-oriented object with which the data is associated ~ translates operating system input events to symbolic object events on an object-by-object basis ~ invokes UIMS actions as required to implement the behavior of the objects.
Updates to application-oriented objects and operating system inputs invoke this functionality. Operating system inputs are translated to symbolic obj ect events via UIMS
configuration data, typically loaded at system startup.
_ 12_ ~ graphical data consisting of vector-based graphical primitives and symbolic graphical attributes such as color, drawing style, and text characteristics ~ a hierarchical structure, whereby any display list may contain other display lists as well as graphical data ~ the display lists, their contained display lists, and the graphical data are sorted from lowest layer (underlying) to highest layer (overlying) relative to the containing display list.
~ traverses the display list hierarchy in either ascending and descending sort order performing vector-by-vector conversion of graphical primitives to raster images (rendering). This traversal can be constrained by an image extent or distance from a specific image pixel ~ determines a set of rendered pixels for each primitive. This is based on the primitive vectors and a translation of the symbolic graphic attributes for drawing styles and/or text characteristics ~ determines a value to be applied against the raster image for each rendered pixel. This is based on a translation of the symbolic graphic attributes for color ~ determines a logical function for each rendered pixel specifying how the pixel value is to be applied against the raster image. This is based on a translation of the symbolic attributes for color, drawing styles, and/or text characteristics. For transparent pixels, the logical function leaves the corresponding pixel in the raster image unchanged, while for opaque pixels the logical function replaces the corresponding pixel in the raster image. Other logical functions provide different visual effects ~ updates one or more raster images from the rendered pixel set, values, and functions determined from a primitive ~ copies some or all of one or more raster images to the hardware video memory.
The presentation manager invokes this functionality to request visual updates or to determine which primitives in the display list contain specific pixels in their rendered pixel set. Symbolic graphical attribute translation to pixel sets, values, and logical functions is through a mapping specified by UINIS configuration data, typically loaded at system startup. This mapping supports transparency through transparent colors and hollow fill drawing styles.
~ an array of pixel values arranged exactly as required for video display ~ overlying obj ects have been rendered after underlying obj ects, so that pixels rendered for the overlying objects modify or replace those of underlying objects.
Figure 11 depicts the algorithm used to update areas beneath the transparent user windows. An application-oriented object behind a transparent window is updated through a change in logical state 53. The presentation manager updates the object representation in the display list by modifying the graphical primitives and attributes associated with that object to reflect its new state 54. The renderer then traverses the hierarchical display list structure as follows. The current display list is set to the top level display list 55. While the end of the current display list has not been reached 56 , the next item in the display list is processed 57. If this item is not an embedded display list 58, the renderer determines the rendered pixel set, pixel values, and logical functions for the graphical data associated with the item 59. The renderer updates the raster images from the rendered pixels 60. This continues until the end of the current display list has been ' -14-reached 56. If an item in the display list is itself an embedded display list 58, the renderer pushes the current display list onto a LIFO stack 61, and sets the current display list to the embedded display list 62. The renderer continues processing with this display list 56.
When the current display list has been completely processed 56, and it is not the top level display list 63, the renderer sets the most recently pushed display list as the current display list 64, and continues the processing of that display list 56. If the completed display list is the top level display list 63, rendering is complete. The renderer copies the updated raster images to video memory 65. Note that all graphical items in the display list are rendered 59, 60, regardless if they are overlain by an opaque or transparent object. In the opaque case, the rendered pixels of the underlying object are replaced by the rendered pixels ofthe overlying object 60. In the transparent case, the rendered pixels of the underlying item are unaffected by the rendered pixels of the overlying item 60.
Figure 12 depicts the algorithm used to implement behavior for objects which are invisible. The operator moves a tracking device connected to the system hardware. The 1 S operating system sends a notification of the motion 66 and a report on the new tracking position to the presentation manager 67. The presentation manager invokes the renderer to determine which primitives in the display lists, searched from uppermost to lowermost layers, contain the current tracking pixel in their rendered pixel set 68.
Note that the rendered pixel set also contains all transparent pixels for any primitive. If no primitives are found by the renderer 69, the presentation manager awaits the next operating system event 66. If the list contains at least one primitive, the presentation manager accesses the application-oriented obj ect associated with the first primitive in the list 70. If it can map the operating system event to a symbolic obj ect event for the application-oriented obj ect 71, it invokes the UIMS actions linked to the object event through its behavior definition 72. The object behavior definition either terminates the input event processing or instructs the presentation manager to propagate it through to the next underlying object 73. Ifprocessing is complete, the presentation manager awaits the next operating system event 66. If the event is to be propagated 73, or the event cannot be mapped to a symbolic object event 71, the presentation manager deletes the primitive from the list 74, and continues processing while there are primitives remaining in the list 69.
