## Background
This application is the U.S. national phase of International Application No. PCT/KR2007/004618 filed 20 Sep. 2007 which designated the U.S. and claims priority to Korean Patent Application No. 10-2006-0109984 filed 8 Nov. 2006, the entire contents of each of which are hereby incorporated by reference.
TECHNICAL FIELD
The present invention relates to a method of displaying a menu, and more particularly, to a method of displaying a menu which displays at least one item selected by a user from a menu including a plurality of items.
BACKGROUND ART
In a conventional art, when a user selects an arbitrary item from a menu which includes a plurality of items, the selected item is displayed in a various ways. For example, the text of the selected item is displayed in bold text or in different colored font. In some cases, the background color and text color of the selected item are reversed so that the selected item is differentiated from the other items of the menu. In Korean Patent Registration No. 10-0619900, when an item of a menu is selected by a user, the RBG color value of the item is shifted to a predetermined color value so that the color of the selected item becomes dark.
Also, in a menu including a plurality of items within an image display range having a limit on the number of displayed characters, when a string in a line exceeds the limit on the number of displayed characters, the excess portion of the string is displayed as “ . . . ” to show the string is not fully displayed.
FIG. 1 is a diagram illustrating an example of a screen displaying a menu in a navigation system 100 in a conventional art.
A user inputs “Gang” in a keyword input unit 110 of the navigation system 100, and a search result is displayed in a menu display unit 120. As illustrated in FIG. 1, a string of an item, “Gang-ga-ne cheek meat/Incheon Seo-gu . . . ”, which is selected by the user and represented in a different background color, is actually to be displayed as “Gang-ga-ne cheek meat/Incheon Seo-gu Seoknam 3 11”. However, a portion exceeding a display range is displayed as “ . . . ” due to a limit of screen size. Although an item below the selected item is actually “Gang-ga-ne cheek meat/Incheon Seo-gu Seoknam 5 22”, the item is displayed as “Gang-ga-ne cheek meat/Incheon Seo-gu . . . ” due to the limit of screen size. As described above, in the conventional art, a selected menu item is displayed using a reverse, and the like. However, when a string included in the selected menu is not fully displayed, the user may not exactly determine which item is the item that the user desires to retrieve, using only strings of currently displayed items.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention are described in detail by referring to the figures. However, the present invention is not limited to the embodiments of the present invention.
FIG. 2 is a diagram illustrating a menu including a plurality of items in a navigation system according to an embodiment of the present invention.
The navigation system 200 includes a keyword input unit 210, a menu display unit 220, and a direction key 230. The keyword input unit 210 receives a selection on a keyword for searching a starting location, a destination, or an intermediate point from a user. The menu display unit 220 displays a plurality of items which is retrieved according to the keyword inputted via the keyword input unit 210. In this instance, a top item may be displayed as selected as a default. The direction key 230 is a tool for selecting at least one item from a plurality of items of a menu and inputting the selected at least one item desired to be retrieved.
FIG. 3 is a flowchart illustrating a method of displaying a menu which reduces a font size of a string of a selected item in a navigation system according to an embodiment of the present invention.
In operation S310, a menu display unit 220 of the navigation system 200 displays a menu including a plurality of items to a user. The menu including the plurality of items is retrieved according to a keyword inputted by a keyword input unit 210.
Referring to FIG. 2, the user inputs a keyword “Gang” in the keyword input unit 210, and the retrieved plurality of items such as “Gang-ga-ne rib house/Daejeon Jung-gu . . . ”, “Gang-ga-ne cheek meat/Incheon Seo-gu . . . ”, and “Gang-ga-ne roast beef restaurant/Seoul . . . ” corresponding to the keyword is displayed in the menu display unit 220. In this instance, since strings of each item exceed a limit on a number of displayed characters of an image display range of the navigation system 200, the excess portion of the strings are replaced with “ . . . ”. Accordingly, in “Gang-ga-ne cheek meat/Incheon Seo-gu . . . ” displayed twice in FIG. 2, omitted portions of the strings are different from each other.
In operation S320, the navigation system 200 receives a selection on at least one of the plurality of items of the displayed menu from the user. The user may select at least one or two items among the plurality of items displayed on the menu display unit 220 by operating the direction key 230 of the navigation system 200. A screen displaying that two items of “Gang-ga-ne cheek meat/Incheon Seo-gu . . . ” in FIG. 2 are selected by operating the direction key 230 by the user is illustrated in FIG. 4. In this instance, the two items of “Gang-ga-ne cheek meat/Incheon Seo-gu . . . ” are difficult to distinguish since an end portion of the strings are omitted. A selected item may change every time the direction key 230 is operated, or an item which is selected when the user pushes a separate selection button after operating the direction key 230 may be set to be a selected item.
In operation S330, the menu display unit 220 of the navigation system 200 reduces a font size of a string of the selected at least one item, and displays the string. For example, when two items are selected in operation S320, the strings of the two items, “Gang-ga-ne cheek meat/Incheon Seo-gu . . . ”, selected by the user, are displayed after reducing a font size of the string.
FIG. 4 is a diagram illustrating an example of reducing a font size of a selected string in a navigation system according to an embodiment of the present invention.
In the navigation system 400 of FIG. 4, a user inputs a keyword “Gang” in a keyword input unit 410. A plurality of items of a menu is displayed on a menu display unit 420, the user selects one or more items from among the plurality of items of the menu using a direction key 430. In FIG. 4, the selected item, “Gang-ga-ne cheek meat/Incheon Seo-gu Seoknam 3 11” and “Gang-ga-ne cheek meat/Incheon Seo-gu Seoknam 5 22”, are illustrated as an example. In this instance, a font size of strings of each of the selected items is reduced. As illustrated in FIG. 4, since the font size of strings of each of the selected items is reduced, more of the strings may be displayed. Also, the user may check an accurate content of each item and select “Gang-ga-ne cheek meat/Incheon Seo-gu Seoknam 3 11” as a stating location, a destination, or an intermediate point in a menu.
When the user selects the two items, that is, “Gang-ga-ne cheek meat/Incheon Seo-gu Seoknam 3 11” and “Gang-ga-ne cheek meat/Incheon Seo-gu Seoknam 5 22”, reducing of the font size of the strings of each item indicates that the font size of the string of the selected at least one item is smaller than that of a string of an unselected item such as “Gang-ga-ne rib house/Daejeon Jung-gu . . . ” and “Gang-ga-ne roast beef restaurant/Seoul . . . ”.
However, when the font size of the string of the selected at least one item is reduced to be so small the user may not read, the user may not discern a content of the string or divide each item.
Accordingly, the font size of the string of the selected at least one item which is smaller than that of the string of the unselected item indicates designating a minimum font size which is readable by the user, that is, a threshold font size, not limitlessly reducing a size of the string and displaying the string in the menu screen. Accordingly, a limit for the font size of the string of the selected at least one item, set to be equal to or greater than the threshold font size, exists, and the font size of the string of the selected at least one item is set to display as much of the string as possible within the limit range. That is, according to an embodiment of the present invention, the font size of the string of the selected at least one item is set to be equal to or greater than a predetermined threshold font size and set to display as much of the string as possible. For example, in an environment where the a threshold font size is 5, when an entire string of a corresponding item may be displayed even when a font size is set as 8, a font size of the corresponding item is set as 8 and the string of the corresponding item may be displayed. Also, in an environment where the a threshold font size is 5, when an entire string of a corresponding item may not be displayed even when a font size is set as 5, the font size is not reduced any further, is set as 5, and a string of a selected item is displayed.
According to another embodiment of the present invention, when the user selects an item as described above, a reduced font size of a string may not vary within a threshold font, and may be predetermined. For example, a string of an unselected item is displayed as a font size of 10, and a string of a selected item is displayed as a font size of 8. The predetermined font size may vary in a system or through a menu screen environment setting by the user. According to the present embodiment, it is advantageous that a configuration is simple and more strings of the selected item may be displayed than the string of the unselected item.
FIG. 5 is a flowchart illustrating a method of displaying a menu which displays a selected string in two lines in a navigation system according to an embodiment of the present invention.
In operation S510, a menu display unit 220 of the navigation system 200 displays a menu including a plurality of items retrieved according to a keyword inputted in a keyword input unit 210.
Referring to FIG. 2, the user inputs a keyword “Gang” in the keyword input unit 210, and the plurality of items retrieved according to the keyword such as “Gang-ga-ne rib house/Daejeon Jung-gu . . . ”, “Gang-ga-ne cheek meat/Incheon Seo-gu . . . ”, and “Gang-ga-ne roast beef restaurant/Seoul . . . ” is displayed on the menu display unit 220. In this instance, since strings of each of the plurality of items exceeds a limit on a number of displayed characters of an image display range of the navigation system 200, the excess portion of string is replaced with “ . . . ”. Accordingly, in “Gang-ga-ne cheek meat/Incheon Seo-gu . . . ” displayed twice in FIG. 2, omitted portions of the strings are different from each other.
In operation S520, the navigation system 200 receives a selection on at least one of the plurality of items of the displayed menu from the user. The user may select at least one or two items by operating the direction key 230 of the navigation system 200 among the plurality of items displayed on the menu display unit 220. A screen displaying that two items of “Gang-ga-ne cheek meat/Incheon Seo-gu Seoknam . . . ” in FIG. 2 are selected by operating the direction key 230 by the user is illustrated in FIG. 6. In this instance, the two items of “Gang-ga-ne cheek meat/Incheon Seo-gu . . . ” are difficult to distinguish since an end portion of the string is omitted. A selected item may change every time the direction key 230 is operated, or an item which is selected when the user pushes a separate selection button after operating the direction key 230 may be set to be a selected item.
In operation S530, when an entire string of the selected at least one item is not fully displayed in one line, the menu display unit 220 of the navigation system 200 displays the string in at least two lines. For example, strings of the two items of “Gang-ga-ne cheek meat/Incheon Seo-gu Seoknam . . . ” which are selected by the user in operation S520 are displayed in two lines, since the entire string is not fully displayed.
FIG. 6 is a diagram illustrating an example of displaying a selected string in two lines in a navigation system according to an embodiment of the present invention.
In the navigation system 600 of FIG. 6, a user inputs a keyword “Gang” in a keyword input unit 610. Then, a plurality of items of a menu is displayed on a menu display unit 620, and the user selects one or more items from the plurality of items of the menu using a direction key 630. In FIG. 6, “Gang-ga-ne cheek meat/Incheon Seo-gu Seoknam 3 11” is displayed as “Gang-ga-ne cheek meat/Incheon Seo-gu” in a first line and “Seoknam 3 11” in a second line. Also, in FIG. 6, “Gang-ga-ne cheek meat/Incheon Seo-gu Seoknam 5 22” is displayed as “Gang-ga-ne cheek meat/Incheon Seo-gu” in a first line and “Seoknam 5 22” in a second line. When a number of characters of a selected string is greater than a number of characters which may be displayed in a first line within a menu screen display range, the string may be divided into two lines as illustrated in FIG. 6, or when the selected string is longer than the menu screen display range, the string may be divided into at least two lines and displayed. Accordingly, more characters of an item may be displayed on the menu. Also, the user checking an accurate content of each of the plurality of items may exactly select “Gang-ga-ne cheek meat/Incheon Seo-gu Seoknam 3 11” on the menu.
FIG. 7, FIG. 8, and FIG. 9 are diagrams illustrating a menu screen to which a method of reducing a font size of a selected string is applied, a menu screen to which a method of displaying a selected string, which may not be displayed in one line, in at least two lines, and a menu screen to which the above-described two methods are applied, in a navigation system according to an embodiment of the present invention.
In FIG. 7, a “Gang” is inputted in a keyword input unit 710 and a plurality of items retrieved is displayed on a menu display unit 720. When “Gang-ga-ne roast beef restaurant/Seoul Gangnam-gu . . . ” is selected using a direction key 730, the string of selected item exceeds a display character limit of the menu display unit 720 although a font size of the string is reduced as described above. Accordingly, a user may not exactly distinguish the selected item from a below item of “Gang-ga-ne roast beef restaurant/Seoul . . . ”.
In FIG. 8, when the user selects an item of “Gang-ga-ne roast beef restaurant/Seoul Gangnam-gu Nonhyeon-dong 1000”, the menu display unit 720 displays a string of the selected item in two lines as described above. When the string of the selected item is longer than the two lines illustrated in FIG. 8, the string may be displayed in a plurality of lines. However, when a selected item includes at least four lines, the menu display unit 720 where a number of lines which may be displayed is limited may not enable the user to compare and select. In FIG. 8, the menu display unit 720 may display up to four lines.
FIG. 9 is a diagram illustrating an example where a font size of a selected item of “Gang-ga-ne roast beef restaurant/Seoul Gangnam-gu Nonhyeon-dong 1000” is reduced and displayed in two lines in order to enable a user to obtain accurate information about “Gang-ga-ne roast beef restaurant” on a menu screen.
