2. Description of the Related Art The 1948 EDVAC computer
System development is often cited as the beginning of the computer age. Since that time, computer systems have evolved into very sophisticated devices that can be found in many different settings. Computer systems typically include hardware (for example,
It includes a combination of semiconductors, circuit boards, etc.) and software (eg, computer programs). As advances in semiconductor processing and computer architecture have increased the capabilities of computer hardware, more sophisticated computer software has evolved to take advantage of the higher performance of hardware, making it far more powerful than several years ago. The current computer system has resulted.

[0003] Early computer systems required extensive command knowledge to perform any type of function by the user. These computers used what is called a command line, where certain commands had to be entered to perform any type of operation. This limited use of the computer to those who had the time to learn a number of relatively crisp commands.

[0004] Later computer systems used more sophisticated user interfaces to make it easier for computer users to perform functions without knowledge of the particular command. The most common modern interface is a graphical user interface, or GUI. In the GUI, certain symbols, menus, or other mechanisms activated by a computer user using a pointing device (eg, a mouse, trackball) to perform a number of commonly performed tasks. used. These graphical mechanisms are usually designed to be somewhat consistent and self-explanatory to make it as easy as possible for the user to perform common functions.

In most graphical interfaces, a document is displayed on a portion of the screen called a window. If the document is large, only a partial view of the document will be visible in the window at one time. To display other parts of the document, a graphical device called a scroll bar is used. The scroll bar allows a user to move a document down or sideways using a pointing device. Specifically, using the scroll bar, the user can click on a slider within the scroll bar and drag it or click elsewhere on the scroll bar to view other parts of the document. Can be moved to the part.

[0006] Many graphical interfaces allow a user to change the size of the document displayed by the interface. The process of changing the displayed size of a document is commonly referred to as "zooming."
Called. For example, when the displayed size is made larger, it is said to be "zoomed in", and when the displayed size is made smaller, it is said to be "zoomed out." With zoom-in, the user can see the document in more detail and can see smaller features better. Similarly, with zoom out, the user can see more parts of the document at the same time, but with less detail and resolution in general.

[0007] Many graphical interfaces allow a user to start with a view of a suitably sized document and provide the ability to zoom in using a mouse or other pointer. For example, some applications facilitate zooming by allowing the user to highlight a portion of the document with the mouse and then release the mouse (so that the application zooms to the highlighted portion of the document). To This can be repeated as desired. For some applications, zoom is also called a "zoom stack"
To allow the user to zoom in and out of previously used views.

Although these techniques are somewhat effective,
It does not give the user complete control of the display screen.
Specifically, the user cannot dynamically view the adjusted view during zooming. Thus, the user often needs to guess the appropriate amount of zoom and adjust the zoom again if the guess is incorrect. Further, the system does not allow the user to select how much to zoom out, except for zooming to a previous amount.

[0009] Without an improved mechanism for controlling the amount of zoom used for document display, effective and efficient work on large documents remains hampered by the limitations of current graphical user interfaces. .

[0010]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method and apparatus for controlling a display zoom in a graphical user interface.

Recordable media such as M and transmission media such as digital and analog communication links are included.

Turning to FIG. 2, an exemplary user interface 300 incorporating a scroll bar zoom controller according to a preferred embodiment is shown. The user interface 300 includes a scroll bar 302 having a slider 304 that slides within a scroll bar area 306 to facilitate movement of a user to view different document portions. As with normal systems, slider 304 scrolls
At the top of the bar area 306, the user interface displays the beginning of the document. Similarly, when the slider 304 is moved to the bottom of the scroll bar area 306, the bottom of the document is displayed on the user interface. In the example shown, the user uses a pointing device to move the slider 304.
Click and drag to move down in the document. The user interface 300 shown in FIG. 2 also includes a second scroll bar 314 that facilitates moving the document view horizontally.

Some scroll bars make it easier to navigate in a document by clicking on a location within the exposed scroll bar area 306 or by clicking the up and down arrows 308. ,
This is not always provided. In addition, some scroll bars adjust the size of the slider opposite the relative size of the displayed document. Thus, a small slider 304 indicates a relatively large document, and a large slider 304 indicates a relatively small document.

According to a preferred embodiment of the present invention, FIG.
Includes a scroll bar zoom controller that gives the user the ability to dynamically control the display zoom. Specifically, the scroll bar 302 displays a zoom icon 3
20 and 322, and scroll bar 314
Includes zoom icons 324 and 326, each of which allows the user to adjust the display zoom. In a preferred embodiment of the present invention, a zoom icon is located adjacent to the respective slider. To adjust the zoom, the user must
Click and drag one of the icons. A user·
An interface dynamically changes the display zoom in response to dragging the zoom icon. Thus, the user is provided with the ability to directly control the amount of zoom provided by the user interface when displaying a document.

For example, by clicking on the zoom icon 324 and dragging to the right, the display size of the document is zoomed and the view is moved toward the right side of the document. The result of clicking and dragging the zoom icon 324 to the right is shown in FIG. Specifically,
Clicking and dragging the zoom icon 324 to the right increases the display size while reducing the size of the slider in the opposite proportion. Further, by clicking and dragging the zoom icon 324 to the right, the center of the display is moved toward the right side of the displayed document. On the other hand, if the user selects zoom by clicking on the zoom icon 326 and dragging to the left, the center of the display will be:
Move toward the left side of the document.

Similarly, the user may select the zoom icon 32
Zooming can also be performed by clicking on 0 and dragging down, or by clicking on the zoom icon 322 and dragging up. Click on the zoom icon 320 and drag it down to
The display size increases, and the center of the display is moved toward the bottom of the document. Similarly, the zoom icon 32
Clicking on 2 and dragging it up increases the display size, moving the center of the display towards the top of the document.

Thus, the user has control over how the image is displayed, and the user can add or remove data in any desired direction.

The preferred embodiment of the present invention provides certain advantages when zooming out. As mentioned above, most prior art systems use zooming and viewing of the display.
Does not provide the user with the ability to control out. Instead, the user can select a predefined zoom or
You can only zoom out to the previously used view. In contrast, the preferred embodiment of the present invention allows the user to zoom out by clicking on one of the zoom icons and dragging outward. This will increase the size of the slider,
Therefore, the display is zoomed out. This allows the user to control the zooming process by dragging the zoom icon until the desired view is obtained. Further, in a preferred embodiment, the user can select the direction of zoom out by selecting the zoom icon to click and drag out. Turning to FIG. 4, the user interface 300 is shown after the user has clicked on the zoom icon 324 and dragged left to zoom out the view and move it to the left of the document. Similarly, the user clicks on the zoom icon 320 and
Zoom out by dragging, or
By selecting the zoom icon 322 or 326, the user can zoom out in other directions.
Thus, in a preferred embodiment, the user is given unprecedented control over the amount and direction of zoom out.

In a preferred embodiment, the user interface dynamically updates the display while the user is dragging the zoom icon. Thus, the user can "see" the zoom occurring while dragging the zoom icon. by this,
It allows the user to zoom exactly to the desired display size without having to "guess" what the zoom will be. This eliminates the problem of past zoom controllers that required the user to zoom multiple times before obtaining the user's desired display size. This is particularly useful when zooming out, as the user can see the zoom happen and stop when the desired display size is reached. In contrast, previous solutions, as noted above, give users little control over zooming out.

The user interface 300 shown in FIGS. 2 and 3 includes both a horizontal scroll bar and a vertical scroll bar, but in other embodiments, instead, a horizontal scroll bar or a vertical scroll bar. Note that only scroll bars can be used. Typically, this depends on the type and relative dimensions of the document displayed via the user interface. Also note that in the preferred embodiment, the size of the associated slider is adjusted to indicate a change in the document display size. Thus, the slider itself indicates the amount of zoom currently being displayed.

It should also be noted that a horizontal zoom icon and a vertical zoom icon can be implemented to zoom proportionally in both directions, or to cause only a zoom in a particular direction. For example, when implemented to zoom proportionally, clicking and dragging the vertical zoom icon changes the horizontal zoom by the same percentage. Thus, both the horizontal and vertical display size and slider size can be adjusted by clicking and dragging the zoom icon on either the horizontal or vertical scroll bar. This type of implementation is desirable when the displayed document is best viewed using a constant vertical / horizontal ratio. For example, image files are generally best kept with a fixed ratio, because changes in relative ratios distort the document.

On the other hand, other documents such as graphs and text documents can be zoomed independently in different directions. In this case, the application must always dynamically adjust the relative dimensions of the document. For example, if the displayed document is a graph of data,
The interface may serve to zoom only in the direction corresponding to the activated zoom icon and keep the other zoom unchanged. In this case, the user interface preferably adjusts the relative proportion of the displayed document to match the changed display characteristics.

Thus, the preferred embodiment of the present invention can be implemented to zoom proportionally or independently, as required by the user when working with certain types of applications and documents.

Accordingly, a preferred embodiment of the present invention provides a method and apparatus for controlling the display zoom of a graphical user interface. The preferred embodiment provides a modified scroll bar that includes two zoom icons that can be used to dynamically zoom the display size of the graphical user interface. Specifically, by clicking and dragging the zoom icon, the user can:
The display size can be dynamically adjusted. The user
When dragging the zoom icon, the view is dynamically updated so that the user can see the zoom occur and stop when the desired amount of zoom is reached. In a preferred embodiment, the zoom icon is
