A user is enabled to easily set processing conditions with simple operations of a pointing device, such as a mouse. When a gesture operation operating a pointer being dragged corresponds to a predetermined operation retained in advance, an information processing device sets processing condition defined in advance correspondingly to the corresponding predetermined operation. For example, a user performs the gesture operation of the pointer on a print setting screen of a figure with the use of the pointing device, such as a mouse. The trace of the pointer is a predetermined operation defined in advance for setting the sheet direction to be horizontal, for example. A graphical user interface processing unit of the information processing system determines that the pointer operation is the horizontal sheet setting and sets the sheet direction to be horizontal in the print processing conditions.
