Abstract: A display scrolling method for scrolling content displayed on a display screen of a display device according to a user operation includes the steps of, when a pointer of a pointing device is started to be dragged, calculating an amount of scrolling of the content to be scrolled with respect to a unit amount of movement of the pointer on the basis of a distance between the position of the pointer and a predetermined reference point; and displaying the content by scrolling the content displayed on the display screen by the determined amount of scrolling in a direction associated with a moving direction of the pointer.

Abstract: The present invention provides an information presentation method for presenting specific information in a basic presentation frame image on a display, the method comprising the steps of: indicating a time axis in the basic presentation frame image in one direction of the basic presentation frame image; providing a presentation area extended along the time axis in the basic presentation frame image; and presenting the specific information in the presentation area at a location along the time axis indicated by and corresponding to chronological information pertained to the specific information.

Abstract: A method of retrieving and selecting content includes the steps of detecting a motion tempo of a user; determining whether a time during which the detected motion tempo is continuously outside a threshold range of the motion tempo corresponding to content being played back exceeds a waiting time that is set or calculated; and retrieving and selecting content suitable for the motion tempo of the user if the motion tempo of the user is outside the threshold range for a time period longer than the waiting time.

Abstract: An information providing method includes a step of setting a relative chronological scale having a reference year set to be a calendar year designated as a birth year or a calendar year of a birth year calculated from a designated age, creating a chronology in which pieces of information related to individual eras on the relative chronological scale are indicated, and displaying the created chronology on a display, and a step of changing a range of era presented on the display of the chronology in response to a change instruction.

Abstract: A content-retrieval device includes first and second operation units, a display unit, storage storing contents, and a control circuit. The control circuit shows at least two thumbnails of the contents stored in the storage and an image of a mark indicating one of the thumbnails on the display unit, performs filtering, when showing the thumbnails, for the shown thumbnails under a predetermined selection condition, changes the strength of the selection condition under which the filtering is performed when the first operation unit is operated, and changes the thumbnail indicated by the mark image to another of the thumbnails when the second operation unit is operated.

Abstract: A method of using contents includes the steps of setting public time information and private time information, the public time information being associated with each content and defined universally for use by a large number of unspecified users, the private time being associated with the content and defined for use by a small number of particular persons, and searching for a content according to the public time information and/or the private time information and using the content detected in the searching.

Abstract: A content list display method includes the step of displaying a list of private content owned by a user and public content not owned by the user on a screen by using a predetermined common attribute as a search key attribute for search and display such that a difference between the private content and the public content can be visually recognized.

Abstract: A playback device includes a storing unit storing a contents database in which contents including at least music and tempo information indicating the tempo of the music are correlated with each other; a playback unit for performing playback of the contents; a tempo measuring unit for measuring an exercise tempo obtained along with the body movements of a user; a searching unit for searching contents from the contents database based on the information of the measured exercise tempo by the tempo measuring unit; and a contents selecting unit for selecting the contents searched by the searching unit as contents to be played by the playback unit.

Abstract: A video playback apparatus includes a thumbnail creating unit for creating thumbnail image data for a video file, and a user operation unit for receiving an instruction from a user. The thumbnail creating unit divides a total playback duration time T of the video file into 2ˆn intervals and creates the thumbnail image data from the first frame of each of the divided intervals. The thumbnail creating unit then supplies the created thumbnail image data to an image displaying unit to display thumbnail images. Upon the user operation unit receiving a first predetermined operation, the thumbnail creating unit increments the value n by 1 to increase the number of thumbnail images. Upon the user operation unit receiving a second predetermined operation, the thumbnail creating unit decrements the value n by 1 to decrease the number of thumbnail image.

Abstract: A data display apparatus includes: an extraction condition setting section that sets, based on an original data row where a plurality of data are arranged in a predetermined order, an extraction condition of extraction data that is to be displayed on a predetermined display section; and an extraction data display section that displays, out of an extraction data row where the extraction data extracted from the original data row based on the extraction condition are arranged in the predetermined order, the extraction data that are within a predetermined range in a predetermined display size on the display section.
