INFORMATION PROCESSING APPARATUS AND NON-TRANSITORY COMPUTER READABLE MEDIUM

1 . An information processing apparatus comprising:

a processor configured to

receive a display instruction to display a display window from an operator;

automatically display the display window on a display at a basic display position determined according to a predetermined rule, in response to determining that movement history information of a plurality of movement instructions of a display window by the operator does not satisfy a first condition; and

automatically display the display window on the display at a changed position that is offset from the basic display position, in response to determining that the movement history satisfies the first condition.

2 . The information processing apparatus according to claim 1 , wherein

the movement history information comprises information indicating a movement direction and a movement amount of the display window from the basic display position, and

the changed display position is a position moved in a movement direction based on the movement direction included in the movement history information, by a movement amount based on the movement amount included in the movement history information, from the basic display position determined by the display instruction.

3 . The information processing apparatus according to claim 2 , wherein

the processor displays the display window at a position with the smallest amount of edges of a screen which are displayed on the display before the display window is displayed and which are hidden when the display window is displayed, among the changed display position and one neighboring position or a plurality of neighboring positions of the changed display position.

4 . The information processing apparatus according to claim 3 , wherein

the processor

calculates an index value that

increases as the amount of edges hidden when the display window is displayed increases, and

increases as a distance from the changed display position increases, for each of the changed display position and the one neighboring position or the plurality of neighboring positions of the changed display position, and

displays the display window at a position where the index value is the smallest.

5 . The information processing apparatus according to claim 1 , wherein

the display window comprises a plurality of types of buttons,

the movement history information includes information indicating a movement direction of the display window from the basic display position and a button operated after a movement, and

when (i) the operator tends to operate a first button after moving the display window in a first movement direction and (ii) the operator tends to operate a second button after moving the display window in a second movement direction, the processor

displays a divided window including the first button at a position moved in the first movement direction from the basic display position based on the movement history information, and

displays a divided window including the second button at a position moved in the second movement direction from the basic display position based on the movement history information.

6 . A non-transitory computer readable medium storing a program that causes a computer to execute information processing, the information processing comprising:

receiving a display instruction to display a display window from an operator;

automatically displaying the display window on a display at a basic display position determined according to a predetermined rule, in response to determining that movement history information of a plurality of movement instructions of a display window by the operator does not satisfy a first condition; and

automatically displaying the display window on the display at a changed position that is offset from the basic display position, in response to determining that the movement history satisfies the first condition.

7 . An information processing apparatus comprising:

means for

receiving a display instruction to display a display window from an operator;

automatically displaying the display window on a display at a basic display position determined according to a predetermined rule, in response to determining that movement history information of a plurality of movement instructions of a display window by the operator does not satisfy a first condition, and

automatically displaying the display window on the display at a changed position that is offset from the basic display position, in response to determining that the movement history satisfies the first condition.
