Title: Graduated visual and manipulative translucency for windows

Abstract:
Methods and systems for providing graphical user interfaces are described. overlaid, Information-bearing windows whose contents remain unchanged for a predetermined period of time become translucent. The translucency can be graduated so that, over time, if the window&#39;s contents remain unchanged, the window becomes more translucent. In addition to visual translucency, windows according to the present invention also have a manipulative translucent quality. Upon reaching a certain level of visual translucency, user input in the region of the window is interpreted as an operation on the underlying objects rather than the contents of the overlaying window.

Description:
RELATED APPLICATION 
     This application is a continuation of application Ser. No. 09/467,316 filed Dec. 20, 1999, now U.S. Pat. No. 6,670,970, the entire contents of which are incorporated herein by reference. 
    
    
     BACKGROUND 
     The present invention relates generally to graphical user interfaces for computer systems. More particularly, the present invention relates to systems and methods for interfacing users with applications which provide for greater flexibility in the operation of both applications and user interfaces, specifically situations involving graphical user interfaces including overlapping windows. 
     The evolution of the computer industry is unparalleled in its rate of growth and complexity. Personal computers, for example, which began as little more than feeble calculators with limited memory, tape-driven input and monochrome displays are now able to tackle almost any data processing task. While this meteoric increase in power was almost sufficient to satisfy the demand of application designers and end users alike, the corresponding increase in complexity created an ease-of-use problem which the industry was somewhat slower in solving. Thus, designers were faced with a new challenge: to harness this computing power in a form usable by even those with relatively little computer training to smooth the transition of other industries into a computer-based information paradigm. 
     As a result, in the early to mid-1980&#39;s many new I/O philosophies, such as “user friendly”, “WYSIWYG” and “menu driven” came to the forefront of the industry. These concepts are particularly applicable to microcomputers, also known as personal computers, which are intended to appeal to a broad audience of computer users, including those who previously feared and mistrusted computers. An important aspect of computers which employ these concepts was, and continues to be, the interface which allows the user to input commands and data and receive results, which is commonly referred to as a graphical user interface (GUI). 
     The success of this type of interface is evident from the number of companies which have emulated the desktop environment. Even successful concepts, however, must continually be improved in order to keep pace with the rapid growth in this industry. The advent of multimedia, especially CD-ROM devices, has provided vast quantities of secondary storage which have been used to provide video capabilities, e.g., live animation and video clips, as regular components of application displays. With these and other new resources at their disposal, application designers and users alike, demand additional functionality and greater ease of use from the desktop environment. 
     To consider the challenges associated with continuing GUI design, consider as an example of a GUI which has evolved over time the Find™ user interface and information management system (simply “Finder™ user interface” hereafter) which runs on the Apple Macintosh™ computer. The Finder™ user interface is based on the aforedescribed display principles using “windows” and “icons” to help manage computer information. The main or root window is called the “desktop” area, or more generally the primary display region. The desktop, or primary display region, is always open (displayed on the screen with its contents accessible or at least partially accessible), and takes up substantially the full display screen area when other windows are not open. The desktop is usually visible in the background when other windows are open. 
     Existing inside any particular window, including the desktop itself, are other information identifiers called “icons.” An icon is a screen identifier associated with a particular collection of computer information. Typically an icon may represent a “file” which is either a collection of data or a program or program segment. An icon also may represent the closed state of a window. Icons are graphic images displayed on the computer screen and usually correspond to the type of information stored within the file. Icons give the user access to the particular file represented by the graphic image when the icon is visible. The use of icons and windows is well known in the art. 
     The “file” is the information packet that the user wishes to utilize, create or modify; each particular file has an associated name identifying the file. Therefore, any given file may be located in the information management system by knowing a file name, an iconographic representation associated with the name, or a window locator name. All information (files) situated within a particular window are identified with that particular window&#39;s own identification location within the computer information management system. Therefore, any particular file information can be retrieved knowing its particular identification name and its window name. Accordingly, the resulting screen display utilizing the Finder™ user interface may be broken down into multiple windows and graphic icons. 
     Another important element of this (and other) conventional user interfaces is a screen cursor. The cursor allows direct user control over the user interface as described above. The Finder™ user interface is complemented with a “mouse” and a corresponding “pointer” which makes up the cursor control device. The user has control over the mouse, which is an electromechanical device that translates two-dimensional mouse movement into a two-dimensional screen position movement represented by, for example, a pointer or arrowhead. The user contacts and directs the mouse. When the mouse is moved freely on a table top, then the pointer on the screen will move in a similar and proportional manner. The mouse also contains one or more push buttons which can be used to effectuate control over the cursor pointer by selecting or deselecting specific icons or other display tools. It is said that the cursor pointer is “activated” when the mouse button is depressed and the pointer remains active until the button is released. Pointer activation may also be initiated by sequences of mouse button presses, such as a “double click” interaction which involves rapidly pressing the mouse button press twice in sequence. 
     Access to information in a conventional user interface system for a display management system is therefore based on windows, icons and pointer movement of the cursor. To access a file, the cursor pointer is placed on the visible icon or visible file name and the pointer is activated. A closed window may be represented by an icon or a window name. A window opens when the pointer of the cursor rests on the visible icon or visible name representing the closed state of the window and the pointer is activated. Within the open window, files may be displayed by icon or by name. An open window, of various geometries, may be rectangular and will exist within the display area of the main viewing screen on the desktop. Multiple windows may be open at one time, typically with the most foreground window corresponding to the most recently opened window and the background windows representing those opened previously. In the organization scheme described, it is appreciated that files are nested within windows and windows can be nested within other windows; the main or root window being the desktop area, or primary display region. 
     During a session using a window-based information system, many windows can be open at one time with many displayed icons within. Windows may overlap and partially, or entirely, hide other windows or icons. What results is that the particular information the user wants to obtain may be hidden behind several layers of windows and may be difficult to access; when an icon is hidden by another window it is temporarily not accessible. This has been referred to in the industry as the “window overlap” problem. There are several instances where window overlap problems routinely arise in the usage of conventional user interfaces. For the purposes of this particular invention, a window overlap problem of particular interest involves floating windows which provide feedback information to a user regarding a particular operation or application. 
     Those familiar with computers having graphical user interfaces will recognize the floating window as a useful, yet sometimes annoying phenomenon. Consider, for example, the floating window  10  illustrated in  FIG. 1  which provides feedback for a speech recognition program. More specifically, the floating window  10  overlays existing windows, e.g., document window  14 , to provide the user with feedback regarding whether a sound has been heard and whether an utterance has been recognized by the speech recognition program. However, the floating window  10  only provides useful information when the user is actively engaged in issuing speech commands and, therefore, only conveys relevant information to the user during relatively short intervals. Nonetheless, floating window  10  remains on the desktop as long as the speech recognition program is active, often obscuring documents or other underlying windows. When the floating window  10  obscures such underlying windows, the user can neither view nor interact with the contents thereof. 
     Thus, it can be seen that there remains a need in the art to design a GUI which permits a user to receive the useful information provided by floating windows while at the same time providing greater availability to the user of the underlying windows&#39; content. 
     SUMMARY 
     According to exemplary embodiments of the present invention, these and other drawbacks and difficulties of conventional GUIs are overcome by providing such floating windows with varying visual and manipulative qualities. For example, a floating window that has not been updated with new information within a predetermined time period will become translucent so that the underlying window or windows are then visible to the user. Other actions or omissions may also serve as a trigger for graduated translucency of windows according to the present invention. Moreover, as the floating window becomes translucent, the user can click-through to the underlying window(s) to interact with its contents. When information on the floating window is updated, it can return to being opaque until the predetermined time period has elapsed again without new information being presented. 
     According to one exemplary embodiment of the present invention, the floating window may become translucent in steps. For example, the floating window may initially be displayed as completely opaque and then, after the predetermined time period expires, may have its opacity reduced in steps of, for example, twenty-five percent. The floating window can have a lower limit of translucency as well. Each of these parameters may be set by the application which generates the floating window or they may be set by the system or the user. 
     By applying graduated visual translucency, as well as manipulative translucency, a user is able to receive the benefits of an information-bearing floating window without having to move the floating window to reach underlying content. Moreover, the change in visual translucency provides a focus mechanism to the user who will readily associate a return to opacity with new information being presented on the floating window.

     DETAILED DESCRIPTION 
     In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular circuits, circuit components, techniques, etc. in order to provide a thorough understanding of the present invention. However, it will be apparent to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known methods, devices, and circuits are omitted so as not to obscure the description of the present invention. 
     Exemplary embodiments of the present invention can be implemented on an Apple Macintosh™ computer system using the Finder™ user interface. However, it will be readily appreciated by those skilled in the art that user interfaces and elements of user interfaces according to the present invention can be used in combination with any system having a processor and a display. In general, such computer systems, as illustrated in block diagram form by  FIG. 2 , comprise a bus  300  for communicating information, a processor  301  coupled with the bus for processing information and instructions, a random access memory  302  coupled with the bus  300  for storing information and instructions for the processor  301 , a read only memory  303  coupled with the bus  300  for storing static information and instructions for the processor  301 , a data storage device  304  such as a magnetic disk and disk drive or CD ROM drive coupled with the bus  300  for storing information and instructions, a display device  305  coupled to the bus  300  for displaying information to the computer user, an alphanumeric input device  306  including alphanumeric and function keys coupled to the bus  300  for communicating information and command selections to the processor  301 , a cursor control device  307  coupled to the bus for communicating information and command selections to the processor  301 , and a signal generating device  308  coupled to the bus  300  for communicating command selections to the processor  301 . 
     The display device  305  utilized with the computer system and the present invention may be a liquid crystal device, cathode ray tube, or other display device suitable for creating images and alphanumeric characters (and ideographic character sets) recognizable to the user. The cursor control device  307  allows the computer user to dynamically signal the two dimensional movement of a visible symbol (cursor) on a display screen of the display device  305 . Many implementations of the cursor control device are known in the art including a trackball, mouse, joystick or special keys on the alphanumeric input device  306  capable of signaling movement of a given direction or manner of displacement. It is to be appreciated that the cursor also may be directed and/or activated via input from the keyboard using special keys and key sequence commands. Alternatively, the cursor may be directed and/or activated via input from a number of specially adapted cursor directing devices, including those uniquely developed for the disabled. In the discussions regarding cursor movement and/or activation within the preferred embodiment, it is to be assumed that the input cursor directing device or push button may consist any of those described above and specifically is not limited to the mouse cursor device. 
       FIG. 3  illustrates an exemplary computer system that in which the present invention can be implemented. It will be appreciated that this computer system is one of many computer systems that may can include the present invention. Therein, a keyboard  400  with keys  402  and keypad  404  is attached to the computer  406  along with a mouse device  408  and mouse push button(s)  410  for controlling the cursor. The mouse device  408  and push button  410  make up a cursor control device  307 . It will be appreciated that many other devices may be used as the cursor control device  307 , for instance the keyboard  400  may be substituted for the mouse device  408  and button(s)  410  as just discussed above. The computer  406  also typically contains a one or more media drives  411  (e.g., floppy disk, hard disk or CD ROM) and a display screen  412 . 
     Having described exemplary computer systems in which user interfaces according to the present invention can be implemented, the discussion now turns to a description of such user interfaces. According to exemplary embodiments of the present invention, the visual and manipulative characteristics of windows can be varied over time. Consider, for example, the information bearing window  500  illustrated in  FIG. 4  in three different visual states. Initially, in panel A, the floating, information-bearing window  500  is completely opaque and contains certain information which can be easily read by the user. 
     After some predetermined period of time has elapsed, e.g., 10 seconds, during which the information displayed in window  500  has not changed, the processor adds some degree of translucency to window  500  as seen in panel B. For example, the window  500  may become 20% translucent. At the point in time depicted in panel B, one can faintly make out the object  510  underlying the information-bearing window  500 , which object  510  was completely obscured while window  500  was opaque in panel A. Next, after a second period of time (which may be the same as or different than the first period of time) during which the information in window  500  remains unchanged, the processor renders window  500  in a final translucent state as seen in panel C, wherein object  510  is even more readily visible, as well as the underlying window entitled “Speakable Items”. For example, the window  500  may be rendered as 40% translucent. If information is changed in window  500  when the window  500  is displayed in the state of either panel B or panel C, then the window is returned to its completely opaque state. Another example of graduated translucency according to exemplary embodiments of the present invention is shown in  FIGS. 7(   a )- 7 ( d ). In  FIG. 7(   a ), the window  700  has no translucency, i.e., is 100% opaque. Next, in  FIG. 7(   b ), the same window  700  is displayed with 20% translucency (80% opaque). Likewise,  FIGS. 7(   c ) and  7 ( d ) portray window  700  with translucencies of 40% and 60%, respectively. 
     Thus,  FIGS. 4 and 7(   a )- 7 ( d ) exemplify the manner in which the present invention provides graduated visual translucency to a window in a graphical user interface. Those skilled in the art will appreciate that although the foregoing example illustrates an embodiment having one step of translucency for window  500  between an opaque state and a translucent state, any number of steps, e.g., one or three or more can be provided. Moreover, the time period between steps can also be set to any desired value or values. For example, the time period between the completely opaque state depicted in  FIG. 7(   a ) and the 20% translucent state of  FIG. 7(   b ) may be 5 seconds, the time period between the 20% translucent state of  FIG. 7(   b ) and the 40% translucent state of  FIG. 7(   c ) may be 3 seconds and the time period between the 40% translucent state of  FIG. 7(   c ) and the 60% translucent state of  FIG. 7(   d ) may be 2 seconds. 
     The visual translucency of windows according to the present invention can be generated according to any known method including, as will be appreciated by those skilled in the art, blending the pixels associated with window  500  together with pixels from the underlying window using an algorithm which provides an appearance of translucency. Specific details of such algorithms are beyond the scope of this discussion, however the interested reader is directed to U.S. Pat. No. 5,949,432, entitled “Method and Apparatus for Providing Translucent Images on a Computer Display”, assigned to Apple Computer, Inc., the disclosure of which is expressly incorporated herein by reference, for further details of one exemplary technique for creating such a translucent effect. In using such blending techniques, a variable degree of translucency (or alternatively opacity) can be obtained, e.g., by varying a ratio of pixels taken from the overlaid window  500  relative to pixels taken from the underlying objects or background. For example, by making the ratio of pixels selected from window  500  relative to pixels selected from the underlying window in panel B of  FIG. 4  greater than the same ratio used by the processor  301  to render panel C in  FIG. 4 , a lesser degree of translucency is provided for window  500  in panel B as compared with panel C. Such a ratio can be expressed as a percentage as mentioned above, e.g., window  500  in panel B is 20% translucent whereas window  500  in panel C is 40% translucent. 
     The parameters mentioned above that are associated with the generation of graduated, visual translucency according to the present invention can be provided to the processor by an application which is associated with the window  500 . For example, if a speech recognition program indicates that an information-bearing, floating window is to be created on the graphical user interface to provide the user with feedback regarding the status of the speech recognition program, the application can pass values for these parameters to an appropriate functional layer of the computer operating system as shown in  FIG. 5 . Therein, an operating system  600  includes, among other functional elements not shown here, a window manager  610  and an event manager  620 . The window manager  610  includes a definition of a window having variable visual translucency (a VVT window), which definition identifies the particular parameters to be passed such that the window manager  610  can create the window  500  on the graphical user interface. For example, the window manager  610  may include a VVT definition which includes the following elements: 
     VVT WindowDef 
     
         
         
           
             [Region]—specifying the region of the desktop in which to render the VVT window; 
             [Initial translucency]—specifying the translucency percentage of the initial state (subsequent to the opaque state) of the VVT window; 
             [Final translucency]—specifying the translucency percentage of the final state for the VVT; 
             [Decay]—rate at which window becomes more translucent between initial and final translucency states, e.g., 10% every five seconds without changes to the displayed information; 
             [First time period]—time after which opaque window enters initial state if information displayed therein remains unchanged; 
             [Manipulative translucency]—translucency at which input in window region operates on underlying object(s).
 
To create a VVT window using this exemplary definition, application  630  makes a call for a new VVT window to the window manager  610 , including a specification of the parameters set forth in the VVTWindowDef, e.g., VVT (Region, 20%, 60%, 10%/5 seconds, 10 seconds). The window manager  610  would then render the VVT window in the designated region with the desired variable translucent properties. Once again, those skilled in the art will appreciate that the above-described window definition is simply illustrative and that other definitions having different parameters can be used to achieve the same or similar effects. Moreover, other parameters can be added to the VVT window definition. For example, a transition effect can be added which lets the user know that the window  500  is beginning to fade or when the window becomes opaque once again, e.g., a brief flash or sound effect, so that the user is informed that the information being displayed in the window  500  has not changed recently or has just been updated, respectively.
 
           
         
       
    
     According to further exemplary embodiments of the present invention, manipulative transparency can also be provided to window  500 . For example, when the window  500  reaches a certain visual translucency, e.g., a percentage specified by the application  630  in the window call (or specified by the user or operating system), then cursor operations or other user input are interpreted by the event manager  620  as operations on the underlying window or objects rather than an operation on the contents of window  500 . To illustrate this point, suppose that the application  630  called for a window  500  as seen in  FIG. 4  wherein the initial translucent state and the manipulative translucency point corresponded to one another. Then, when the window  500  was displayed as shown in panel B, positioning the cursor (not shown) over the faintly visible object  510  under window  500  and “double-clicking”, would be interpreted by the event manager  620  as an operation on the underlying object  510  instead of an operation on the contents of window  500 . By providing manipulative as well as visual transparency, the present invention is able to provide the user with the useful feedback information conveyed by window  500 , while also allowing the user to easily view and work with underlying objects when the information in window  500  is not rapidly changing. 
     Thus methods according to the present invention are exemplified by the flow chart of  FIG. 6 . Therein, at step  640 , a VVT window is displayed in its opaque state. If the window&#39;s information or other contents have not changed within a predetermined update interval, at step  650 , then the window is rendered in its initial translucent state at step  660 . Otherwise, if the window&#39;s contents have changed, then the window remains in its opaque state. Of course, if the application  630  has only requested a VVT window with a single translucent state, then this may also be the final translucent state. Next, at step  670 , it is determined whether the window  500  has reached the manipulative level of translucency. If so, then the flow proceeds to step  680  wherein user input is interpreted as operating on the underlying window or object(s). Otherwise, the flow continues to step  690  where it is again determined (after some predetermined delay) whether the window&#39;s contents have changed. If so, then the window becomes opaque again. If not, then the process moves to block  700  wherein the window is made more translucent according to the parameters supplied in the call used to create the window. 
     The above-described exemplary embodiments are intended to be illustrative in all respects, rather than restrictive, of the present invention. Thus the present invention is capable of many variations in detailed implementation that can be derived from the description contained herein by a person skilled in the art. For example, the foregoing exemplary embodiments describe an application of the present invention wherein graduated translucency is triggered when information displayed in a window is unchanged for a predetermined period of time. However other triggering events (lack of events) may be used to invoke graduated translucency as described herein. For example, lack of user input, e.g., via keyboard, cursor or voice, may result in a window or other object becoming translucent as described above. 
     Moreover, although the foregoing exemplary embodiments relate to the provision of graduated translucency in the direction of from opaque to translucent, those skilled in the art will appreciate that the graduated change in visual output can also be applied from translucent to opaque. For example, when an input is received for a window that has reached some degree of translucency, that window may transition back to complete (or substantially complete) opacity in one or more steps. All such variations and modifications are considered to be within the scope and spirit of the present invention as defined by the following claims.
