Abstract

Provided is an information processing device including a detection unit configured to detect a user operation, and a display control unit configured to display a list including list items, and perform display of, in response to a detected user operation, causing new list items to gradually appear in the list.

What is claimed is: 
     
         1 . An information processing apparatus comprising:
 a display;   a touch panel;   a control unit configured to
 detect, on the touch panel, a pinch out operation which increases a distance between two objects, 
 control to display a first thumbnail and a second thumbnail on the display, 
 control to display an animation in which the first thumbnail gradually appears, based on a first granularity of information when an amount of the pinch out operation exceeds a first threshold, and 
 control to display an animation in which the second thumbnail gradually appears, based on a second granularity of information when an amount of the pinch out operation exceeds a second threshold which is larger than the first threshold. 
   
     
     
         2 . The information processing apparatus of  claim 1 , wherein the second granularity of information is finer than the first granularity of information. 
     
     
         3 . The information processing apparatus of  claim 1 , wherein the thumbnails appear regardless of a position of the pinch out operation on the touch panel. 
     
     
         4 . The information processing apparatus of  claim 1 , wherein additional thumbnails appear in the space between existing thumbnails. 
     
     
         5 . The information processing apparatus of  claim 1 , wherein
 the control unit is further configured to control to display a third thumbnail on the display, the position of the third thumbnail moving based on the pinch out operation.   
     
     
         6 . The information processing apparatus of  claim 5 , wherein
 the control unit is further configured to control display of an animation in which the size of the third thumbnail remains same and the size of the first thumbnail is same as the size of the third thumbnail after the pinch out operation is completed.   
     
     
         7 . The information processing apparatus of  claim 5 , wherein
 the control unit is further configured to control display of an animation in which the first thumbnail is appeared from a position which is overlapped by the third thumbnail and is displayed in a position which is not overlapped by the third thumbnail.   
     
     
         8 . The information processing apparatus of  claim 1 , wherein
 when the first granularity of information or the second granularity of information is refined to reach a limit, the number of the displayed additional thumbnails is zero.   
     
     
         9 . The information processing apparatus of  claim 1 , wherein an amount of the pinch out operation comprises:
 a movement amount or a movement speed.   
     
     
         10 . An information processing method comprising:
 detecting, on a touch panel, a pinch out operation which increases a distance between two objects;   displaying a first thumbnail and a second thumbnail on a display;   displaying an animation in which the first thumbnail gradually appears, based on a first granularity of information when an amount of the pinch out operation exceeds a first threshold; and   displaying an animation in which the second thumbnail gradually appears, based on a second granularity of information when an amount of the pinch out operation exceeds a second threshold which is larger than the first threshold.   
     
     
         11 . A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer causes the computer to execute a method, the method comprising:
 detecting, on a touch panel, a pinch out operation which increases a distance between two objects;   displaying a first thumbnail and a second thumbnail on a display;   displaying an animation in which the first thumbnail gradually appears, based on a first granularity of information when an amount of the pinch out operation exceeds a first threshold; and   displaying an animation in which the second thumbnail gradually appears, based on a second granularity of information when an amount of the pinch out operation exceeds a second threshold which is larger than the first threshold.   
     
     
         12 . An information processing apparatus, comprising:
 a display;   a touch panel; and   a control unit configured to
 detect, on the touch panel, a pinch in operation which decreases a distance between two objects, 
 control to display a first thumbnail and a second thumbnail on the display, 
 control to display an animation in which the first thumbnail gradually disappears based on a first granularity of information when an amount of the pinch in operation exceeds a first threshold, and 
 control to display an animation in which the second thumbnail gradually disappears based on a second granularity of information when an amount of the pinch in operation exceeds a second threshold which is larger than the first threshold. 
   
     
     
         13 . The information processing apparatus of  claim 12 , wherein the second granularity of information is coarser than the first granularity of information. 
     
     
         14 . The information processing apparatus of  claim 12 , wherein the thumbnails disappear regardless of a position of the pinch in operation on the touch panel. 
     
     
         15 . The information processing apparatus of  claim 12 , wherein
 the control unit is further configured to control to display a third thumbnail on the display, the position of the third thumbnail moving based on the pinch in operation.   
     
     
         16 . The information processing apparatus of  claim 15 , wherein
 the control unit is further configured to control to display an animation in which the size of the third thumbnail remains same and the size of the first thumbnail is same as the size of the third thumbnail before the pinch in operation is completed.   
     
     
         17 . The information processing apparatus of  claim 15 , wherein
 the control unit is further configured to control to display an animation in which the first thumbnail is displayed in a position which is not overlapped by the third thumbnail, and is disappeared from a position which is overlapped by the third thumbnail.   
     
     
         18 . The information processing apparatus of  claim 15 , wherein an amount of the pinch in operation comprises:
 a movement amount or a movement speed.   
     
     
         19 . An information processing method, comprising:
 detecting, on a touch panel, a pinch in operation which decreases a distance between two objects;   displaying a first thumbnail and a second thumbnail on a display;   displaying an animation in which the first thumbnail gradually disappears based on a first granularity of information when an amount of the pinch in operation exceeds a first threshold; and   displaying an animation in which the second thumbnail gradually disappears based on a second granularity of information when an amount of the pinch in operation exceeds a second threshold which is larger than the first threshold.   
     
     
         20 . A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer causes the computer to execute a method, the method comprising:
 detecting, on a touch panel, a pinch in operation which decreases a distance between two objects;   displaying a first thumbnail and a second thumbnail on a display;   displaying an animation in which the first thumbnail gradually disappears based on a first granularity of information when an amount of the pinch in operation exceeds a first threshold; and   displaying an animation in which the second thumbnail gradually disappears based on a second granularity of information when an amount of the pinch in operation exceeds a second threshold which is larger than the first threshold.
