## Title
Graphical user interface for accessing data

## Abstract

A graphical user interface for accessing data can display hierarchical information in an efficient organized layout that users may easily navigate. In one embodiment, subject headings are contained within cells that form a column. Information related to the subject headings is contained within cells which are formed in rows that are adjacent and orthogonal to the column. The information contained within the rows of cells is related to the closest subject heading in the column.
One of the cells contained within the rows is a focus cell. The user may activate the focus cell to access a lower level within the hierarchy of information where the contents of the focus cell become a subject heading in the cell within the column. The user may browse the data by selecting a non-focus cell causing the contents within the rows of cells to appear to move from cell to cell.

## Background
BACKGROUND
1. Field of the Invention
The present invention relates generally to graphical user interfaces and methods. More particularly, the present invention relates to systems and methods of a graphical user interface for accessing data.
2. Background Art
As electronic features increase and the availability of information becomes more prevalent, consumers are finding interactive guides necessary to navigate data. For example, consumers may use an electronic program guide to find their favorite television show, use a cell phone interactive guide to program their favorite ringtones, or engage a search engine to search websites on the Internet.
Available graphical user interfaces that act as interactive guides, however, may display information inefficiently. Existing solutions, such as electronic program guides and Internet directories, are two dimensional. As soon as the consumer drills down or across a set of information, the view of the information categories may be lost. Further, the amount of data displayed to the user may be too narrow. As a result, the user may miss relevant data.
Moreover, some existing solutions may block a large portion of the visible area on the screen of an electronics device, thereby eliminating useful screen space. For example, when searching Google, a consumer may be inundated with pages full of unrelated search results that fill the browser window. In another example, the electronic program guide may block a television screen with multiple windows of programs and programming times.
Cell phones, personal digital assistants, and digital devices with relatively little display area are constrained by limited interactive guides that attempt to manipulate large, complex sets of data with limited user inputs. The results have been inefficient, complex, and difficult for the consumer to use.

DETAILED DESCRIPTION OF THE EMBODIMENTS
A graphical user interface for accessing data can display hierarchical information in an efficient organized layout that users may easily navigate. In one embodiment, subject headings are contained within cells that form a column. Information related to the subject headings is contained within cells which are formed in rows that are adjacent and orthogonal to the column. In this embodiment, the information contained within the rows of cells is related to the closest subject heading in the column.
One of the cells contained within the rows is a focus cell. In one embodiment, the focus cell does not move. The user may cause the content within the rows of cells to appear to move from cell to cell, thereby allowing the user to browse through the data, by selecting one of the cells contained within the rows which is not the focus cell. The user may also activate the focus cell which allows the user to access additional information.
The effect of activating the focus cell may differ depending on the position within the hierarchical information displayed by the graphical user interface. For example, activating the focus cell may cause the graphical user interface to display data at a lower level within the hierarchical information. If the graphical user interface is already displaying the lowest level of the hierarchical information, then activating the focus cell may cause either details about the information within the focus cell to be displayed or additional functions to become available.
In an embodiment, the graphical user interface allows the user to perform complex searches using simple input devices. In an example, the user need only the capability to move up, down, left, and right (e.g. with arrow keys), to make a cell selection or to activate the focus cell. In this example, complex searches may be accomplished where both screen size and input/output interface are limited (e.g. a cell phone or personal digital assistant).
FIGS. 1-3, 4a-7a, and 4b-6b illustrate possible examples of the graphical user interface after the displays depicted in FIGS. 1-3 in accordance with a particular configuration of the graphical user interface. Although FIGS. 1-3, 4a-7a, and 4b-6b depict the graphical user interface as a tabular grid of cells, the graphical user interface may also be depicted in a more fanciful manner. In some embodiments, the graphical user interface may comprise the grid of cells, advertisements and a media window. In another embodiment, the graphical user interface may be depicted as a horizontal virtual cylinder. The cylinder could be drawn so as to look three-dimensional, with shape, shading, and distortion of text within the cells to create an illusion of depth, so that the central row appears closest to the viewer. Moreover, the columns of the virtual cylinder may be depicted as rotating to display new information. Similarly, the graphical user interface may depict cell content moving from cell to cell within the adjacent row of cells along the length of the virtual cylinder in a direction orthogonal to the virtual cylinder rotation. The graphical user interface may be implemented on many digital devices, including a computer, television, cell phone, personal digital assistant, or any other digital device with a display.
FIG. 1 illustrates a graphical user interface 100 for accessing classified advertisements, in accordance with one embodiment. In this example, the graphical user interface 100 comprises a grid of cells. Within the grid, a column of cells 105 contains cells 110a, 110b, and 110c. Subject headings are contained within the cells 110a, 110b, and 110c. In this example, cell 110a contains the subject heading “baby stuff”, cell 110b contains the subject heading “cars”, and cell 110c contains the subject heading “computers”. In other embodiments, there may be any number of cells containing subject headings within the column of cells 105.
Also within the grid, adjacent rows of cells 115, 120, and 125 extend orthogonally from the column of cells 105. The content within each cell 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140c is associated with its closest subject heading within the column of cells 105. In this example, the adjacent row of cells 115 contains cells 130a, 130b, and 130c. Cells 130a, 130b, and 130c contain information related to the subject heading within the closest cell 110a in the column of cells 105. In this example, the content of cells 130a (“beds”), 130b (“clothing”), and 130c (“high chairs”) contain information that is associated with the subject heading “baby stuff” contained within the cell 110a. Similarly, the content of cells 135a (“by location”), 135b (“by make”), and 135c (“by price”) within the row of cells 120 contain information that is associated with the subject heading “cars” contained within the cell 110b. Moreover, the content of cells 140a (“by mfr.”), 140b (“by price”), and 140c (“by type”) within the row of cells 125 contain information that is associated with the subject heading “computers” contained within the cell 110c. In other embodiments, there may be any number of rows of cells 115, 120, and 125, with any number of cells 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140c, which may contain information.
In one embodiment, a history bar 150 is displayed above the grid of cells. The history bar 150 depicts the general name or topic of the hierarchical information being viewed as well as a current position within the hierarchical information depicted by the graphical user interface 100. In this example, the history bar 150 only displays “Classifieds” since the user is viewing the most general information available.
In this embodiment, cell 135b is a focus cell. The focus cell 135b is identified by a black focus frame 145. In other embodiments, the focus cell 135b may be identified by a focus frame 145 that is of a different color. In still other embodiments, the focus cell 135b may use any of a variety of known display techniques to indicate that it is a different color or otherwise distinct from the other cells within the graphical user interface.
The user may choose to select one of the cells 130a, 130b, 130c, 135a, 135c, 140a, 140b, or 140c, from the rows of cells 115, 120, or 125. By selecting one of the cells 130a, 130b, 130c, 135a, 135c, 140a, 140b, or 140c, information within the cells 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, or 140c may appear to shift. The contents of the selected cell may now be displayed within the new focus cell 135b. This process is further described herein.
There may be many ways the user may select the cell 130a, 130b, 130c, 135a, 135c, 140a, 140b, or 140c. The user may position a cursor over the cell 130a, 130b, 130c, 135a, 135c, 140a, 140b, or 140c, and then press an “enter” or a selection key on an input/output device, such as a mouse, keyboard, touch-screen, or remote control. Alternately, the user may select the cell 130a, 130b, 130c, 135a, 135c, 140a, 140b, or 140c by pressing arrow keys on an input/output device.
Similarly, a “text input” function may be included to assist the user to select the cell 130a, 130b, 130c, 135a, 135c, 140a, 140b, or 140c. In an example, the user may type the contents of cell 130b in order to select the cell 130b. In this example, the user may type a few or all of the letters or numbers contained within the cell 130b in order to select the cell 130b. The user may type characters or numbers with a keyboard, touch-screen, or cellphone.
Those skilled in the art will appreciate that there may be many ways to select the cell 130a, 130b, 130c, 135a, 135c, 140a, 140b, or 140c. 
In the example depicted, the user selects cell 135a which contains “by location”. An example of the resulting graphical user interface 100 may appear as FIG. 2.
FIG. 2 illustrates the graphical user interface 100 for accessing classified advertisements after the user selected an adjacent cell 135a to the focus cell 135b in FIG. 1, in accordance with one embodiment. The focus cell 135b now contains “by location”. The content within the other cells 130a, 130b, 130c, 135a, 135c, 140a, 140b, and 140 has shifted within the rows of cells 115, 120, and 125. As a result, new information is now displayed within the cells 130a (“appliances”), 135a (“by year”), and 140a (“by type”) while information formerly contained in the cells 130c, 135c, and 140c visible in FIG. 1 is no longer visible in FIG. 2.
In another example, if the user had selected cell 135c which contained “by price” in FIG. 1, the focus cell 135b would then contain “by price” and the contents within the other cells 130a, 130b, 130c, 135a, 135c, 140a, 140b, or 140 would have shifted in the opposite direction.
In the example depicted, the user activates the focus cell 135b which contains “by location”. An example of the resulting graphical user interface 100 may appear as shown in FIG. 3.
FIG. 3 illustrates the graphical user interface 100 for accessing classified advertisements after the user activated the focus cell 135b of FIG. 2, in accordance with one embodiment. By activating the focus cell 135b, the information formerly contained within the cells 135a (“by year”), 135b (“by location”), and 135c (“by make”) in FIG. 2 is displayed as subject headings within cells 110a, 110b, and 110c, respectively, within the column of cells 105 as shown in FIG. 3. New information is now contained within the cells 130a (“2005”), 130b (“2004”), 130c (“2003”), 135a (“within 5 mi.”), 135b (“in my city”), 135c (“other location”), 140a (“Acura”), 140b (“Alfa Romeo”), and 140c (“Audi”). The history bar 150 displays the name of the hierarchical information as “Classifieds” and further displays the position within the hierarchical information depicted by the graphical user interface 100 as the “Cars” subject heading.
In the example depicted, the user activates the focus cell 135b which contains “in my city”. Depending on the configuration of the graphical user interface 100, an example of the resulting graphical user interface 100 may appear as shown in FIG. 4a, or, alternately, the resulting graphical user interface 100 may appear as shown in FIG. 4b. The configuration of the graphical user interface 100 may be dictated by the programming or the structure of the hierarchical information itself.
FIG. 4a illustrates the graphical user interface 100 for accessing classified advertisements after the user activated the focus cell 135b in FIG. 3, in accordance with one embodiment. Similar to the graphical user interface 100 depicted in FIG. 3, the information formerly contained within the cells 135a (“within 5 ml.”), 135b (“in my city”), and 135c (“other location”) in FIG. 3 is displayed as subject headings within the cells 110a, 110b, and 110c, respectively, within the column of cells 105 as shown in FIG. 4a. New information is now contained within the cells 130a (“Acura”), 130b (“Alfa Romeo”), 130c (“Audi”), 135a (“Acura”), 135b (“Alfa Romeo”), and 135c (“Audi”). The history bar 150 displays the name of the hierarchical information as “Classifieds” and the position within the hierarchical information depicted by the graphical user interface 100 as “Cars—in my city”.
In the example depicted, the user activates the focus cell 135b which contains “Alfa Romeo”. An example of the resulting graphical user interface 100 may appear as shown in FIG. 5a. 
FIG. 5a illustrates the graphical user interface 100 for accessing classified advertisements after the user activated the focus cell 135b in FIG. 4a, in accordance with one embodiment. Similar to the graphical user interface 100 depicted in FIG. 4a, the information formerly contained within the cells 135a (“Acura”), 135b (“Alfa Romeo”), and 135c (“Audi”) in FIG. 4a is displayed as subject headings within the cells 110a, 110b, and 110c, respectively, within the column of cells 105 as shown in FIG. 5a. New information is now contained within the cells 130a (“by model”), 130b (“by price”), 130c (“by mileage”), 135a (“by model”), 135b (“by price”), 135c (“by mileage”), 140a (“by model”), 140b (“by price”), and 140c (“by mileage”). The history bar 150 displays the name of the hierarchical information as “Classifieds” and the position within the hierarchical information depicted by the graphical user interface 100 as “Cars—in my city, Alfa Romeo”.
In the example depicted, the user activates the focus cell 135b which contains “by price”. An example of the resulting graphical user interface 100 may appear as shown in FIG. 6a. 
FIG. 6a illustrates the graphical user interface 100 for accessing classified advertisements after the user activated the focus cell 135b in FIG. 5a, in accordance with one embodiment. Similar to the graphical user interface 100 depicted in FIG. 5a, the information formerly contained within the cells 135a (“by model”), 135b (“by price”), and 135c (“by mileage”) in FIG. 5a is displayed as subject headings within cells 110a, 110b, and 110c, respectively, within the column of cells 105 as shown in FIG. 6. New information is now contained within the cells 130a (“147”), 130b (“156”), 130c (“Sportwagon”), 135a (“<$5,000”), 135b (“$5-10,000”), 135c (“$10-15,000”), 140a (“<50,000 ml”), 140b (“50-100,000 ml”), and 140c (“>100,000 ml”). The history bar 150 continues to display the name of the hierarchical information as “Classifieds” and the position within the hierarchical information depicted by the graphical user interface 100 as “Cars—in my city, Alfa Romeo, by price”.
In the example depicted, the user activates the focus cell 135b which contains “$5-10,000”. An example of the resulting graphical user interface 100 may appear as shown in FIG. 7a. 
FIG. 7a illustrates the graphical user interface 100 for accessing classified advertisements after the user activated the focus cell 135b in FIG. 6a, in accordance with one embodiment. Similar to the graphical user interface 100 depicted in FIG. 6a, the information formerly contained within the cells 135a (“<$5,000”), 135b (“$5-10,000”), and 135c (“$10-15,000”) in FIG. 6a is displayed as subject headings within cells 110a, 110b, and 110c, respectively, within the column of cells 105 as shown in FIG. 7. New information is contained within the cells includes 130a (“'71 Spider $4950”), 130b (“'77 Spider $4950”), 135a (“'95 164 $9,650”), 135b (“'87 Spider $9,000”), 135c (“88 Spider $7,900”), 140a (“'91 Spider $11,995”). In this example, cells 130c, 140b, and 140c do not contain any information because the classified advertisements may have limited available data. The history bar 150 continues to display the name of the hierarchical information as “Classifieds” and the position within the hierarchical information depicted by the graphical user interface 100 now displays “Cars—in my city, Alfa Romeo, by price, $5-10,000”.
Depending on the amount of information present within the hierarchical information, at the lowest level, the information displayed within the cells 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140c, may be highly related to each other thereby allowing the user to view a wide variety of related information within the adjacent cells 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140c. 
As displayed in FIGS. 2-3 and 4a-7a, activating the focus cell 135b allows the user to access the lower level within the information hierarchy. As a lower level is accessed, the new subject headings within the cells 110a, 110b, and 110c are related to the former subject heading (the former contents of cell 110a). The relationship between the subject headings within the cells 110a, 110b, and 110c grows as the user accesses lower levels within the information hierarchy. Consequently, the content within the cells 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140c becomes increasingly related to the subject headings 110a, 110b, and 110c, as well as to each other. As a result, the graphical user interface 100 may display closely related information to the target of the search thereby allowing the user to access closely related information that may be of interest.
For example, in FIG. 3, the information contained within the cells 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140c as well as the subject headings contained within the cells 110a, 110b, and 110c are related to “Cars”. In FIG. 4a, the information contained within the cells 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140c as well as the subject headings contained within the cells 110a, 110b, and 110c are related to “Cars” that are “in my city”. In FIG. 7a, the information contained within the cells 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140c as well as the subject headings contained within the cells 110a, 110b, and 110c are related to “Cars”, particularly “Alfa Romeo”, which are “in my city”, and between the prices of $5-10,000. Although the user may be interested in cars manufactured by Alfa Romeo in the user's city that are between the prices of $5-10,000, the graphical user interface also depicts cars manufactured by Alfa Romeo in the user's city that are both “<$5,000” and “$10-15000” which may be of interest to the user.
It will be appreciated by those skilled in the art that the graphical user interface 100 for accessing data may be used to navigate any hierarchical or structured data structure, including, but not limited to, databases and data trees. For example, the graphical user interface 100 may be operated as an interactive guide for television programming, internet web surfing, media content searching, image searching, audio searching, and data searching.
FIG. 4b illustrates an alternate depiction of the graphical user interface 100 for accessing classified advertisements after the user selected the adjacent cell 135c to the focus cell 135b in FIG. 3, in accordance with one embodiment. The focus cell 135b now contains “other location”. The content within the other cells 130a, 130b, 130c, 135a, 135c, 140a, 140b, and 140 has shifted within the rows of cells 115, 120, and 125. As a result, new information is now displayed within the cells 130c (“2002”), 135c (“ . . . ”), and 140c (“BMW”) while information formerly contained in the cells 130a, 135a, and 140a visible in FIG. 3 is no longer visible in FIG. 4b. 
In the example depicted, the user activates the focus cell 135b which contains “other location”. An example of the resulting graphical user interface 100 may appear as shown in FIG. 5b. 
FIG. 5b illustrates an alternate depiction of the graphical user interface 100 for accessing classified advertisements after the user activated the focus cell 135b in FIG. 4b, in accordance with one embodiment. In this example, new information is displayed within all of the cells 110a, 110b, 110c, 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140c. New subject headings are displayed within 110a (“entire state”), 110b (“city”), and 110c (“[in Italy] provincial”). The new subject headings are related to the contents of the former activated focus cell 135b (“other location”) in FIG. 4b. 
The relationship between the contents of the cells 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140c within the rows of cells 115, 120, and 125, and the subject heading in the closest respective cell 110a, 110b, or 110c within the column of cells 105 is maintained. For example, cells 130a (“Colorado”), 130b (“Connecticut”), and 130c (“Delaware”) are related to the subject heading “entire state” in the closest cell 110a within the column of cells 105. Similarly, cells 135a (“in Colorado”), 135b (“in Connecticut”), and 135c (“in Delaware”) are related to the subject heading “city” in the closest cell 110b within the column of cells 105. Moreover, cell 140a (“Abruzzi”), 140b (“Valle d'Aosta”), and 140c (“Basilicata”) are related to the subject heading “[in Italy] provincia” in the closest cell 110c within the column of cells 105.
The history bar 150 displays the name of the hierarchical information as “Classifieds” and the position within the hierarchical information depicted by the graphical user interface 100 as “Cars—other location”.
In the example depicted, the user activates the focus cell 135b which contains “in Connecticut”. An example of the resulting graphical user interface 100 may appear as shown in FIG. 6b. 
FIG. 6b illustrates an alternate depiction of the graphical user interface 100 for accessing classified advertisements after the user activated the focus cell 135b in FIG. 5b, in accordance with one embodiment. In this example, new information is displayed within all of the cells 130a (“Boston”), 130b (“Roxbury”), 130c (“Salem”), 135a (“Bridgeport”), 135b (“New Haven”), 135c (“New London”), 140a (“Albany”), 140b (“New York”), and 140c (“Schenectady”).
New subject headings which are displayed within 110a (“Massachusetts”), 110b (“Connecticut”), and 110c (“New York”) are related to the former activated focus cell 135b (“in Connecticut”) in FIG. 4b. As described herein, the relationship between the subject headings contained within cells 110a, 110b, and 110c and the formerly activated focus cell 135b may be controlled by the programming or the structure of the hierarchical information itself. As a result, the user may access any different position within the hierarchical information. For example, the user may activate the focus cell and new subject headings are displayed in the cells 110a, 110b, and 110c, within the column of cells 105, and new content is displayed within the cells 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140c. The user may immediately access any lower level, any upper level, or any different position within the same level of the hierarchical information.
FIG. 8 is a flowchart depicting a method for the graphical user interface, as may be used for accessing classified advertisements depicted in FIGS. 1-7, in accordance with one embodiment. FIG. 8 begins in step 800. In step 810, the grid of cells including the column of cells 105 and the adjacent rows of cells 115, 120, and 125 are displayed. Each cell 110a, 110b, and 110c within the column of cells 105 may contain a subject heading. Each cell 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140 within the rows of cells 115, 120, and 125 may contain information associated with the subject headings. In one embodiment, cell 135b is displayed as the focus cell 135b by the focus frame 145.
The column of cells 105 is orthogonal to the adjacent rows of cells 115, 120, and 125. The orientation of the digital device that displays the grid of cells does not alter the dimensional relationship between the column of cells 105 and the adjacent rows of cells 115, 120, and 125. For example, if the adjacent rows of cells 115, 120, and 125 are reoriented to appear as columns, the column of cells 105 will appear to be a row orthogonal to the reoriented adjacent rows of cells 115, 120, and 125 now displayed as columns.
The number of cells 110a, 110b, and 110c within the column of cells 105, the number of adjacent rows of cells 115, 120, and 125, and the number of cells 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140 may be chosen by the user, determined by the graphical user interface, determined by the hierarchical information, dependant upon the viewable dimensions of the digital device, or any one or more other factors.
In step 820, the graphical user interface 100 may receive a user input. If the user input is received, FIG. 8 continues to step 830. If the graphical user interface 100 does not receive the user input, then FIG. 8 ends in step 870.
In step 830, the graphical user interface 100 may receive the selection of one of the cells 130a, 130b, 130c, 135a, 135c, 140a, 140b, or 140 as the user input. If a selection of one of the cells 130a, 130b, 130c, 135a, 135c, 140a, 140b, or 140 is received, then FIG. 8 continues to step 840. Otherwise, FIG. 8 continues to step 850.
In step 840, the grid of cells with the content of the cells shifted within the adjacent rows of cells 115, 120, and 125 is displayed. In one embodiment, the focus cell 135b, the column of cells 105, and the rows of cells 115, 120, and 125 remain fixed. The content of the selected cell 130a, 130b, 130c, 135a, 135c, 140a, 140b, or 140c becomes the content of the focus cell 135b. In one embodiment, the user may select either the cells 135a or 135c, which are to the left and right of the focus cell 135b, or the cells 130b or 140b which are above and below the focus cell 135b. 
If the user selects the cells 135a or 135c, the content of the cells 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140c, within the rows of cells 115, 120, or 125 appears to shift within the rows of cells 115, 120, and 125. New information may appear as the user scrolls the information through the visible cells. For example, if the user selects cell 135a, the contents of cell 135a shift to the focus cell 135b. Similarly, the former contents of cells 130a and 140a may shift to cells 130b and 140b, respectively. Further, the former contents of cells 130b, 135b, and 140b may shift to cells 130c, 135c, and 140c, respectively. The content that was in cells 130c, 135c, and 140c, appears to shift out of the graphical user interface 100. New information may appear within cells 130a, 135a, and 140a. In another example, the user selects cell 135c, and the contents within the cells 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140c within the rows of cells 115, 120, and 125 appear to shift in the opposite direction than the previous example.
If the user selects cells 130b or 140b, the content of the cells 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140c, within the rows of cells 115, 120, or 125 appears to shift within the rows of cells 115, 120, and 125. The subject headings within cells 110a, 110b, and 110c will also appear to shift within the column of cells 105. New information may appear as the user scrolls the information through the visible cells.
For example, if the user selects cell 130b, the contents of cell 130b shift to the focus cell 135b. Similarly, the former contents of cells 130a and 130c may shift to cells 135a and 135c, respectively. Further, the former contents of cells 135a, 135b, and 135c may shift to cells 140a, 140b, and 140c, respectively. The content that was in cells 140a, 140b, and 140c, appears to shift out of the graphical user interface 100. New information may appear within cells 130a, 130b, and 130c. Further, the subject heading within the cell 110a may shift to cell 110b. The subject heading within the cell 110b may shift to the cell 110c. The subject heading that was within the cell 110c may appear to shift out of the graphical user interface 100. A new subject heading may appear in the cell 110a. 
In another example, the user selects cell 140b, and the contents within the cells 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140c within the rows of cells 115, 120, and 125 appear to shift in the opposite direction than the previous example. Similarly, the contents within the cells 110a, 110b, and 110c within the column of cells 105 also appear to shift in the opposite direction than the previous example.
Once step 840 is completed, the graphical user interface 100 returns to step 820 to receive the next user input.
In step 850, the graphical user interface 100 may receive the activation of the focus cell 135b as the user input. If the focus cell 135b is activated, then FIG. 8 continues to step 860. If the focus cell 135b is not activated, then FIG. 8 ends in FIG. 870.
In step 860, the focus cell 135b is activated. The content of the focus cell 135b, along with the content of the cells 135a and 135c within the adjacent row of cells 120 as the focus cell 135b, is displayed as subject headings within the cells 110b, 110a, and 110c, respectively, within the column of cells 105. New information is displayed within the cells 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, and 140c. 
In another embodiment, the user may have the option to select and activate the cell 130a, 130b, 130c, 135a, 135c, 140a, 140b, and 140c within a single action thereby allowing the contents of the selected cell 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, or 140c, along with the contents of the cells within the same row of cells 115, 120, or 125 as the selected cell, to be displayed as subject headings within the contents of the column of cells 105.
After the new display is completed, the graphical user interface 100 waits to receive the next user input in step 820.
Although FIG. 8 depicts a number of functions, those skilled in the art will recognize that the graphical user interface 100 may perform many functions. For instance, a “more information” function may be added to display additional information about the contents of the cell 110a, 110b, 110c, 130a, 130b, 130c, 135a, 135b, 135c, 140a, 140b, or 140c, as well as a “back” function to undo the last selection or activation.
FIG. 9a illustrates three consecutive stages 900a, 900b, and 900c of a graphical user interface for accessing a programming guide in accordance with one embodiment.
In the first stage 900a of the graphical user interface, the history bar 990a displays the name of the hierarchical information as “Program Guide.” The cells 925a (“search”), 930a (“browse”), and 935a (“record”) are within the column of cells 905a. Cells 940a (“by name”), 945a (“by time”), 950a (“by genre”), are within the row of cells 910a. Cells 955a (“by name”), 960a (“by time”), 965a (“by genre”), are within the row of cells 915a. Cells 970a (“by name”), 975a (“by time”), 980a (“by genre”), are within the row of cells 920a. The focus cell 960a (“by time”) is surrounded by the focus frame 985a. 
In the example depicted, the user activates the focus cell 960a which contains “by time”. As a result, the next stage 900b of the graphical user interface may appear.
In the next stage 900b, the former contents of the row of cells 915a are displayed as individual subject headings within the cells 925b, 930b, and 935b. New information is displayed within the cells 940b (“A”), 945b (“B”), 950b (“C”), 955b (“ABC”), 960b (“BBC”), 965b (“CBS”), 970b (“Action”), 975b (“Biography”), and 980b (“Comedy”). The history bar 990b continues to display the title, “Program Guide”, as well as the current position within the hierarchical information, “browse by time”.
In the example depicted in stage 900b, the user activates the focus cell 960b which contains “BBC” to “browse” (depicted in the history bar 990b) the programs available on the “BBC” channel “by time” (depicted as the subject heading contained within cell 930b.) As a result, the next stage 900c of the graphical user interface may appear.
In the next stage 900c, the former contents of the row of cells 915b are displayed as individual subject headings within the cells 925c, 930c, and 935c. New information in the form of television programming is displayed within the cells contained in the row of cells 910c, 915c, and 920c. The history bar 990c continues to display the title, “Program Guide”, as well as the current position within the hierarchical information, “browse by time”. In this example, the television programming information displayed within the cells 945c, 950c, 960c, 965c, 975c, and 980c is related to the closest subject heading within the cells 925c (“ABC”), 930c (“BBC”), and 935c (“CBS”) as well as “by time”.
In this example, the contents of the focus cell 960c is displayed as a television program that is currently being broadcast. The contents of the cells 940c, 955c, and 970c to the left of the focus cell 960c may represent television programs in the past and are left blank in this example. The user may browse a future program broadcasted by the “BBC” by selecting the cell 950c, 970c, or 980c to the right of the focus cell 960c. 
In the example depicted in stage 900c, the user selects the cell 970c to the right of the focus cell 960c. As a result, the next stage 900d in FIG. 9b of the graphical user interface may appear.
FIG. 9b illustrates two further consecutive stages of a graphical user interface 900d and 900e for accessing a programming guide in accordance with one embodiment.
In the stage 900d, the content within each cell 945c, 950c, 960c, 965c, 975c, and 980c have shifted, respectively, to cells 940d, 945d, 955d, 960d, 970d, 975d. The contents of the formerly blank cells 940c, 955c, and 970c have appeared to shift out of the graphical user interface. Similarly, new information is displayed within the cells 950d, 965d, and 980d. 
In the example depicted in stage 900d, the user activates the focus cell 960d. As a result, the next stage 900e of the graphical user interface may appear.
In the stage 900e, the lowest level of the hierarchical information has been achieved. By activating the focus cell 960d, details of the selected program are displayed along with television options to “watch” 987d, “record” 989d, or “record & watch” 991d. By choosing the television options, the graphical user interface may provide the user with the ability to control a television, media device, audio device, or recording device. Those skilled in the art will recognize that many digital devices may be controlled by the user using the graphical user interface.
FIG. 10 illustrates a block diagram of an interactive portion 1000 of the graphical user interface for accessing data, in accordance with one embodiment. The interactive portion 1000 of the graphical user interface comprises a history bar 1050, a column of cells 1005 including cells 1010a, 1010b, and 1010c, a first row of cells 1015 including cells 1030a, 1030b, and 1030c, a second row of cells 1020 including cell 1035a, focus cell 1035b, and cell 1035c, a third row of cells 1025 including cells 1040a, 1040b, 1040c, and a focus frame 1045 surrounding the focus cell 1035b. 
The history bar 1050 is displayed above the interactive portion of the graphical user interface. The history bar 150 may be placed in any position within the display of the digital device. The history bar 150 may also include a feature whereby when the history bar 150 is selected, the user may return to the initial view of the interactive portion of the graphical user interface 1000 or return to any previous action within the interactive portion of the graphical user interface 1000.
FIG. 11 illustrates a block diagram of the graphical user interface for accessing data including advertisements and a media window, in accordance with one embodiment. The graphical user interface 1100 depicts an interactive portion 1000 as in FIG. 10 surrounded by advertisements 1110, 1120, 1130, 1140, 1150, and a media window 1160.
