Subsequently, the control unit 190 controls the signal processing unit 120 and the display unit 140 to process the received service and provide the user with the service.
In this case, the control unit 190 updates the information on the frequency of use of the service and stores the information on the frequency of use of the service in the memory unit 170. Subsequently, the control unit 190 classifies services according to their frequency of use, and controls the UI generation unit 180 to generate a user interface based on the classification result. That is, the control unit 190 classifies services according to their total frequency of use or their recent frequency of use, and controls the UI generation unit 180 to generate a user interface so that the user can utilize the classified services easily.
The service menu in the user interface generated by the UI generation unit 180 is a widget menu which is generated in a widget form.
Hereinbelow, exemplary embodiments of the user interface generated by the UI generation unit 180 are described.
FIGS. 2A to 2G illustrate various types of user interface which are displayed on a display apparatus according to exemplary embodiments of the present invention. Referring to FIGS. 2A to 2G, a main screen 200 displays a broadcast program, and a widget menu window 210 displays icons for services generated according to their frequency of use.
In the widget menu window 210 of FIGS. 2A and 2B, icons such as [N weather], [E stock], [D news], [3-5 times], and [1-2 times] are arranged according to their frequency of use. That is, the most frequently used service is a service regarding [N weather], followed by [E stock] and [D news]. If [N weather] is selected, a first sub window 220 displays information regarding [N weather] as illustrated in FIG. 2A.
Services which are not frequently used by the user are classified in [3-5 times] or [1-2 times]. That is, if [1-2 times] is selected, the first sub window 220 of FIG. 2B displays icons regarding services which have only been used once or twice by the user. Among the icons [D shopping], [A weather], [B weather], [A movie], and [N music] which are displayed on the first sub window 220, if the user selects [B weather], a second sub window 230 displays information regarding [B weather] as illustrated in FIG. 2B.
In FIGS. 2A and 2B, as an example, the three most frequently used icons are displayed on the widget menu window 210, and the remaining services are classified into other two icons according to their frequency of use. The number of frequently used icons which are arranged in the widget menu window 210 can be set by the user. In addition, the number and frequency of use of icons for infrequently used services, such as [3-5 times] and [1-2 times], can be set by the user. In other words, infrequently used services may be classified under [1-5 times] and [6-8 times] icons, or may be classified under [1-2 times], [3-4 times] and [5-6 times] icons.
As illustrated in FIGS. 2A and 2B, since infrequently used services are managed under one or more icons, infrequently used services as well as frequently used services can also be easily found. That is, icons of frequently used services are displayed on the widget menu window 210, and icons of infrequently used services are collected and displayed as lower menus under representative icons, so many icons for all of the services do not have to be displayed in the widget menu window 210. Therefore, the user can find an icon of a desired service easily.
In a widget menu window 210 of FIG. 2C, icons of frequently used services such as [N weather], [E stock], and [D news] are displayed, and infrequently used services are classified under categories desired by the user, such as sport 211 and weather 212. If the user selects weather 212, a first sub window 220 displays icons regarding weather 212 as illustrated in FIG. 2C. Among [A weather], [B weather], [C weather], and [D weather] displayed in the first sub window 220, if the user selects [C weather], a second sub window 230 displays information regarding [C weather], as illustrated in FIG. 2C.
The categories can be modified by the user as desired, and the number of categories displayed in the widget menu window 210 can also be set by the user. That is, FIG. 2C illustrates two categories as an example, but it is possible to have only one category, or three or more categories.
In a widget menu window 210 of FIG. 2D, icons of frequently used services such as [N weather], [E stock], and [D news] are displayed, and infrequently used services are classified according to the user. That is, infrequently used services are classified under icons [user a] and [user b], as illustrated in FIG. 2D. If [user b] is selected, a first sub window 220 displays icons of services used by user b as illustrated in FIG. 2D.
The icons displayed in the first sub window 220 are arranged according to their frequency of use by user b. Among [A weather], [A movie], [N music], and [D mail], which are displayed in the first sub window 220, if [A weather] is selected, a second sub window 230 displays information regarding [A weather] as illustrated in FIG. 2D. Users can be distinguished by allocating a user identification and a password to each user in order for each user to log-in to use the display apparatus 100. Other methods can also be used to distinguish users.
As illustrated in FIGS. 2C and 2D, infrequently used services are classified according to their category or user, so infrequently used services as well as frequently used services can be easily found.
In a widget menu window 210 of FIG. 2E, a plurality of icons [{circle around (1)}], [{circle around (2)}], [{circle around (3)}], [{circle around (4)}], and [{circle around (5)}] are displayed, and each icon includes services classified according their frequency of use. For example, services having a frequency of use of 50% or more are classified in a lower menu under [{circle around (1)}], services having a frequency of use of 30%-50% are classified in a lower menu under [{circle around (2)}], services having a frequency of use of 10%-30% are classified in a lower menu under [{circle around (3)}], services having a frequency of use of 2%-10% are classified in a lower menu under [{circle around (4)}], and services having a frequency of use of 0%-2% are classified in a lower menu under [{circle around (5)}]. Alternatively, the number of services classified under each icon [{circle around (1)}], [{circle around (2)}], [{circle around (3)}], [{circle around (4)}], and [{circle around (5)}] may be limited. That is, the three most frequently used services may be classified under [{circle around (1)}], and services can be allocated to [{circle around (2)}], [{circle around (3)}], [{circle around (4)}], and [{circle around (5)}] in the same manner.
As illustrated in FIG. 2E, if the user selects [{circle around (1)}], a first sub window 220 displays icons [N weather], [E stock], and [D news] which are classified under [{circle around (1)}]. Among [N weather], [E stock], and [D news] which are displayed in the first sub window 220, if the user selects [N weather], a second sub window 230 displays information regarding [N weather], as illustrated in FIG. 2E.
FIG. 2F illustrates that a widget menu window 210 displays an OSD menu for setting the function of the display apparatus 100 as an example. That is, the widget menu window 210 can display frequently used icons of the OSD menu as well as icons of frequently used services. As illustrated in FIG. 2F, if [sound control] is selected, a first sub window 220 displays an OSD menu for setting sound.
The widget menu window 210 of FIG. 2F may display [1-3 times] regarding the frequency of use as illustrated in FIGS. 2A and 2B, or display weather 213 regarding the category as illustrated in FIG. 2C. Although not illustrated in FIG. 2F, the widget menu window 210 may also display icons classified according to the user. As described above, the type of icons displayed on the widget menu window 210 can be set by the user, so the user can utilize the widget menu window 210 in diverse manners.
In a widget menu window 210 of FIG. 2G, a first icon 214, a second icon 215, a third icon 216, a fourth icon 217, and a fifth icon 218 are displayed. Information regarding each service is sequentially displayed on each icon as a slideshow. That is, as illustrated in FIG. 2G, information regarding the N weather service is displayed in the first icon 214 as a slideshow, information regarding the E stock service is displayed in the second icon 215 as a slideshow, and information regarding the D news service is displayed in the third icon 216 as a slideshow.
The fourth icon 217 and the fifth icon 218 display infrequently used services as slide shows. For example, if the fourth icon 217 includes services used by user a as a lower menu, the fourth icon 217 sequentially displays icons corresponding to services used by user a as a slideshow. As another example, if the fifth icon 218 indicates a category regarding weather, the fifth icon 218 sequentially displays icons corresponding to services classified under weather as a slideshow.
Various user interface display methods as described above can be set by the user, and the user can easily select a desired service through a menu arranged according to the frequency of use.
FIG. 3 is a flowchart illustrating a method for displaying a user interface on a display apparatus according to an exemplary embodiment of the present invention.
Referring to FIG. 3, if a user command to select a specific service is input to the display apparatus 100 (S300), the control unit 190 updates information regarding the frequency of use (S310). That is, the control unit 190 checks the frequency of use of the selected service, and stores the checked frequency of use in the memory unit 170. Subsequently, the control unit 190 classifies the services according to the updated frequency of use (S320), and controls the UI generation unit 180 to generate icons corresponding to the classified services (S330).
If a user interface display method has been set (S340-Y), the control unit 190 controls the UI generation unit 180, the video processing unit 125, and the display unit 140 to display a user interface according to the set user interface display method (S360). If a user interface display method has not already been set (S340-N), a user interface display method is set (S350), and the control unit 190 displays a user interface according to the set user interface display method (S360).
As can be appreciated from the above description, the user can easily utilize a desired service using icons generated according to the frequency of use of the service by directly setting a user interface display method.
According to exemplary embodiments of the present invention, the user can easily select a desired service by displaying icons according to the frequency of use.
The foregoing exemplary embodiments are merely exemplary and are not to be construed as limiting the present invention. The present teaching can be readily applied to other types of apparatuses. Also, the description of the exemplary embodiments of the present invention is intended to be illustrative, and not to limit the scope of the claims, and many alternatives, modifications, and variations will be apparent to those skilled in the art.
