Abstract:
1. A content display device comprising: a display hardware unit; a detection hardware unit operable to detect an operation location and an operation amount of a touch input operation; a touchscreen including the detection hardware unit and the display hardware unit, one of which being overlaid on the other; a group selection hardware unit operable to select one of a plurality of groups, each having a plurality of contents belonging thereto; a memory; and one or more processors, wherein the content display device, through execution, by the one or more processors, of a program stored in the memory implements: an extraction unit operable to extract two or more contents from among the plurality of contents belonging to the group selected by the group selection hardware unit; a display control unit operable to (i) based on the operation location detected by the detection hardware unit, calculate for one content from among the two or more contents, which have been extracted by the extraction unit and arranged in sequence, a selected order which indicates an order of the one content, and (ii) cause the display hardware unit to display the one content of the selected order which has been calculated; and a display update unit operable to, each time the operation location detected by the detection hardware unit has moved during a period from calculation of the selected order until the detection hardware unit no longer detects the touch input operation, (i) change the selected order by a number corresponding to the operation amount detected by the detection hardware unit, and (ii) cause the display hardware unit to display a content of the selected order which has been changed; wherein the display control unit is further operable to (i) arrange first display objects that correspond one-to-one to the two or more contents in accordance with the sequence of the two or more contents, and (ii) cause the touchscreen to display the arranged first display objects; the one content for which the display control unit calculates the selected order corresponds to one of the first display objects that has been displayed on the touchscreen at the operation location detected by the detection hardware unit; the display control unit causes the touchscreen to display the first display objects in such a manner that part of the first display objects is distinguishable from a rest of the first display objects, the part containing said one of the first display objects corresponding to the one content of the selected order which has been calculated, a total number of first display objects included in the part corresponding to the operation amount detected by the detection hardware unit; the touchscreen is a pressure-sensitive touchscreen; the detection of the operation amount by the detection hardware unit denotes detection of a pressure level of pressure applied by pressing the touchscreen; the display control unit sets the number corresponding to the operation amount detected by the detection hardware unit in such a manner that the number becomes smaller as the pressure level becomes larger, and the display update unit, each time the operation location has moved during the period from calculation of the selected order until the detection hardware unit no longer detects the operation amount, changes the selected order by the number corresponding to the operation amount detected by the detection hardware unit, the number being set by the display control unit.
