Information processing apparatus, information processing method, and program

Abstract

There is provided an information processing apparatus including a display section which displays, as a first layout state, an object group including a plurality of objects arranged in a first direction, a detection section which detects an operation input that is input to the display section, and a control section which, when the detection section detects an operation input in a second direction that is perpendicular to the first direction, changes the first layout state into a second layout state in which the respective objects constituting the object group which has been selected are spread and pieces of information associated with the plurality of objects, respectively, are displayed.

What is claimed is: 
     
         1 . An information processing apparatus comprising:
 a display section which displays, as a first layout state, an object group including a plurality of objects arranged in a first direction;   a detection section which detects an operation input that is input to the display section; and   a control section which, when the detection section detects an operation input in a second direction that is perpendicular to the first direction, changes the first layout state into a second layout state in which the respective objects constituting the object group which has been selected are spread and pieces of information associated with the plurality of objects, respectively, are displayed.   
     
     
         2 . The information processing apparatus according to  claim 1 ,
 wherein, when the operation input in the second direction is detected by the detection section in the first layout state, the control section moves the respective objects constituting the object group in the second direction in a manner that an arrangement of the selected object group is misaligned.   
     
     
         3 . The information processing apparatus according to  claim 2 ,
 wherein the control section determines a movement distance in the second direction of the respective objects constituting the object group based on information of variables which varies depending on a motion of the operation input.   
     
     
         4 . The information processing apparatus according to  claim 3 ,
 wherein, when the operation input is stopped, the control section returns a display of the respective objects of the object group which have been moved in the second direction to the first layout state when the information of variables at a point of stopping the operation input is less than a predetermined threshold, and the control section allows the display of the respective objects of the object group to become the second layout state when the information of variables at a point of stopping the operation input is equal to or more than the predetermined threshold.   
     
     
         5 . The information processing apparatus according to  claim 4 ,
 wherein the information of variables represents a movement distance or a movement speed of the operation input in the second direction.   
     
     
         6 . The information processing apparatus according to  claim 1 ,
 wherein the control section moves the respective objects constituting the object group in the second direction in a manner that the arrangement of the selected object group is misaligned when a predetermined state change condition is satisfied, and the control section causes the object group displayed in the first layout state to be scrolled in the second direction when the state change condition is not satisfied.   
     
     
         7 . The information processing apparatus according to  claim 6 ,
 wherein the state change condition is that the respective objects constituting the object group are moved in the second direction in a manner that the arrangement of the selected object group is misaligned, by inputting at least once an operation input in the first direction.   
     
     
         8 . The information processing apparatus according to  claim 6 ,
 wherein the state change condition is that a motion of an operation input is not detected for a predetermined time period or longer in the first layout state.   
     
     
         9 . The information processing apparatus according to  claim 1 ,
 wherein the control section causes the second layout state to be displayed regarding, as a reference point, an object among the plurality of objects, which is displayed at an initial contact position which was touched first when there was the operation input in the first layout state.   
     
     
         10 . The information processing apparatus according to  claim 1 ,
 wherein, when an operation input in the first direction is detected by the detection section after a display is changed to the second layout state, the control section returns a display of the display section from the second layout state to the first layout state.   
     
     
         11 . An information processing method, comprising the steps of:
 detecting, by a detection section, an operation input that is input to a display section in which an object group including a plurality of objects arranged in a first direction is displayed as a first layout state; and   changing, by a control section, when the detection section detects an operation input in a second direction that is perpendicular to the first direction, the first layout state into a second layout state in which the respective objects constituting the object group which has been selected are spread and pieces of information associated with the plurality of objects, respectively, are displayed.   
     
     
         12 . A program for causing a computer to function as an information processing apparatus which includes
 a detection control section which causes a detection section to detect an operation input that is input to a display section in which an object group including a plurality of objects arranged in a first direction is displayed as a first layout state, and   a layout control section which, when the detection section detects an operation input in a second direction that is perpendicular to the first direction, changes the first layout state into a second layout state in which the respective objects constituting the object group which has been selected are spread and pieces of information associated with the plurality of objects, respectively, are displayed.
