User interface controlling apparatus, user interface controlling method, and computer program

1. A user interface controlling apparatus comprising:

input means for receiving user operation information; and

display controlling means for controlling display of data in a switched manner on a display unit based on input information from said input means,

said display controlling means exercises control, based on said input information of said input means designating any of upward-, downward-, rightward-, and leftward-directions, of selection of:

a data aggregate to be displayed from data aggregates including different categories of data, wherein said data aggregates are formed of description data defining varying combinations of at least one of text data, picture data, and program information data as said different categories of data,

particular description data, and

any one of the text data, picture data, and program information data constituting said category data for display from the selected description data,

before outputting the selected category data to said display unit.

2. The user interface controlling apparatus according to claim 1 , wherein

said display controlling means exercises control, based on said input information of said input means designating any of said upward-, downward-, rightward-, and leftward directions, of a scrolling display of description titles as identifiers of said data aggregates and, during said scrolling display, of display of the description titles covering the data belonging to the category designated beforehand for display, in a manner different from the description titles not covering said data.

3. The user interface controlling apparatus according to claim 2 , wherein

said display controlling means provides an animated display showing that the description titles not covering the data belonging to the category designated beforehand for display are skipped.

4. The user interface controlling apparatus according to claim 1 , wherein

said display controlling means performs, based on said input information coming from said inputting means designating any of said upward-, downward-, rightward-, and leftward directions, a scrolling display of description titles as identifiers of said data aggregates, as well as a scrolling display of category data in linkage with said description titles, said category data being displayed in a screen area different from that for said description titles.

5. A user interface controlling method comprising:

inputting user operation information; and

controlling display of data in a switched manner on a display unit based on input information from said inputting,

said display controlling exercises control, based on said input information coming from said inputting designating any of upward-, downward-, rightward-, and leftward-directions, of selection of:

a data aggregate to be displayed from data aggregates including different categories of data, wherein said data aggregates are formed of description data defining varying combinations of at least one of text data, picture data, and program information data as said different categories of data,

particular description data, and

any one of the text data, picture data, and program information data constituting said category data for display from the selected description data,

before outputting the selected category data to said display unit.

6. The user interface controlling method according to claim 5 , wherein

said display controlling exercises control, based on said input information coming from said inputting designating any of said upward-, downward-, rightward-, and leftward directions, of a scrolling display of description titles as identifiers of said data aggregates and, during said scrolling display, of display of the description titles covering the data belonging to the category designated beforehand for display, in a manner different from the description titles not covering said data.

7. The user interface controlling method according to claim 6 , wherein

said display controlling gives an animated display showing that the description titles not covering the data belonging to the category designated beforehand for display are skipped.

8. The user interface controlling method according to claim 5 , wherein

said display controlling performs, based on said input information coming from said inputting step designating any of said upward-, downward-, rightward-, and leftward directions, a scrolling display of description titles as identifiers of said data aggregates, as well as a scrolling display of category data in linkage with said description titles, said category data being displayed in a screen area different from that for said description titles.

9. A computer readable storage medium encoded with computer program instructions which when executed by a computer implement a method of exercising control over a user interface, said method comprising:

receiving operation information; and

controlling display of data in a switched manner on a display unit based on input information from said inputting;

said display controlling exercises control, based on said input information coming from said inputting designating any of upward, downward, rightward-, and leftward directions, of selection of:

a data aggregate to be displayed from data aggregates including different categories of data, wherein said data aggregates are formed of description data defining varying combinations of at least one of text data, picture data, and program information data as said different categories of data,

particular description data, and

any one of the text data, picture data, and program information data constituting said category data for display from the selected description data,

before outputting the selected data to said display unit.

10. A user interface controlling apparatus comprising:

an device configured to input user operation information; and

a display controlling device configured to control display of data in a switched manner on a display unit based on input information from said input device,

said display controlling device exercises control, based on said input information coming from said inputting device designating any of upward-, downward-, rightward-, and leftward directions, of selection of:

a data aggregate to be displayed from data aggregates including different categories of data, wherein said data aggregates are made up of description data formed by varying combinations of at least one of text data, picture data, and program information data as said different categories of data,

particular description data, and

any one of the text data, picture data, and program information data constituting said category data for display from the selected description data, before outputting the selected data to said display unit.
