Display control apparatus, display control method, display control program, and recording medium storing the display control program

A display control method, comprising the steps of:

• in the case where an input unit operated in order to change the display state of a plurality of content items displayed on a display screen is subjected to a user operation so as to enclose an arbitrary position on the display screen, detecting whether or not the user operation is a circling operation from a trail from a start point to an end point of the user operation, and if the detection result indicates a circling operation, detecting whether a circling direction is a first direction or a second direction which is opposite to the first direction and detecting a number of revolutions in the circling operation, and determining the area on the display screen enclosed by the trail to be a selection area;
• searching the plurality of content items for relevant content items that correspond to position information included inside the selection area;
• and
• displaying or hiding the relevant content items are according to the circling direction, and in the case of a plurality of relevant content items, determining the number of relevant content items to display or hide from among the relevant content items on the basis of the number of revolutions, such that when the circling direction is detected to be the first direction the determined number of relevant content items are displayed and when the circling direction is detected to be the second direction the determined number of relevant content items are hidden.

A non-transitory computer-readable recording medium having stored thereon a display control program causing a computer to function as:

• circling detecting means configured such that, in the case where an input unit operated in order to change the display state of a plurality of content items displayed on a display screen is subjected to a user operation so as to enclose an arbitrary position on the display screen, the circling detecting means detects whether or not the user operation is a circling operation from a trail from a start point to an end point of the user operation, such that if the detection result indicates a circling operation, the circling detecting means detects whether a circling direction is a first direction or a second direction which is opposite to the first direction and detects a number of revolutions in the circling operation, and also determines the area on the display screen enclosed by the trail to be a selection area;
• content item searching means configured to search the plurality of content items for relevant content items that correspond to position information included inside the selection area;
• and
• content display quantity adjusting means configured to display or hide the relevant content items according to the circling direction, and in the case of a plurality of relevant content items, determine the number of relevant content items to display or hide from among the relevant content items on the basis of the number of revolutions, such that when the circling direction is detected to be the first direction the determined number of relevant content items are displayed and when the circling direction is detected to be the second direction the determined number of relevant content items are hidden.

• and
• a content display quantity adjuster configured to display or hide the relevant content items according to the circling direction, and in the case of a plurality of relevant content items, determine the number of relevant content items to display or hide from among the relevant content items on the basis of the number of revolutions, such that when the circling direction is detected to be the first direction the determined number of relevant content items are displayed and when the circling direction is detected to be the second direction the determined number of relevant content items are hidden.
