in the game process,

the processor performs

executing an item use process upon determination that the user has made an item use motion, with the item acquired and possessed by the user character, based on the user information.

11. The simulation system as defined in claim 10 , wherein

in the game process,

the processor performs

executing the item use process in accordance with at least one of a motion direction of the item use motion, intensity of the item use motion, a type of the item, line-of-sight information of the user during the item use motion, and a state of a predetermined body part of the user used to make the item use motion.

12. The simulation system as defined in claim 1 , wherein

in the game process,

the processor performs

canceling an item possessing state of the user character when a given condition is satisfied, with the item acquired and possessed by the user character.

13. The simulation system as defined in claim 1 , wherein

in the game process,

the processor performs

a notification process of notifying of the item acquisition by an image, sound or vibration when the item is acquired.

14. The simulation system as defined in claim 1 , wherein

in the virtual space setting process,

the processor performs

setting a disposing location of the item in accordance with physical information of the user.

15. The simulation system as defined in claim 1 , wherein

in the display process,

the processor performs

generating, as the display image, a display image for a head mounted display worn by the user to cover a field of view of the user.

16. An image processing method comprising:

an information acquisition process of acquiring user information including at least one of position information, direction information, and posture information of a user;
