Information processing apparatus, information processing method, and program

A non-transitory computer-readable medium for use with an apparatus including a display, a touch panel, and a processor, wherein the computer-readable medium is encoded with instructions which, when executed by the processor, cause the apparatus to:

• display, in a region of the display, a portion of a scrollable display object including a plurality of respective items, the display object including an edge and having at least one of the plurality of respective items located adjacent the edge;
• detect a movement operation in which an operating object moves at least partially in a first direction along the touch panel;
• determine, during the movement operation, whether the edge of the display object has reached the region of the display;
• if, during the movement operation, the edge of the display object has not reached the region, scroll the display object in the first direction within the region;
• if, during the movement operation, the edge of the display object has reached the region, refrain from moving the edge of the display object in the first direction;
• detect, during the movement operation, an overdrag operation in which the operating object moves at least partially in the first direction at a time after the edge of the display object has reached the region of the display;
• and
• in response to detecting the overdrag operation, display a graphic element in the region that at least partially overlays the at least one of the plurality of respective items adjacent the edge.

A method for operating an apparatus including a display and a touch panel, the method comprising:

• displaying, in a region of the display, a portion of a scrollable display object including a plurality of respective items, the display object including an edge and having at least one of the plurality of respective items located adjacent the edge;
• detecting a movement operation in which an operating object moves at least partially in a first direction along the touch panel;
• in response to a first portion of the movement operation, scrolling the display object in the first direction within the region of the display;
• determining that the edge of the display object reaches the region during the movement operation;
• detecting, during a second portion of the movement operation, an overdrag operation in which the operating object moves at least partially in the first direction at a time after the edge of the display object has reached the region of the display;
• refraining from moving the edge of the display object in the first direction in response to the second portion of the movement operation;
• and
• in response to detecting the overdrag operation, displaying a graphic element in the region that at least partially overlays the at least one of the plurality of respective items adjacent the edge.
