Simulation system, processing method, and information storage medium

A simulation system comprising a processor including hardware,

• the processor being configured to perform:
• a virtual space setting process of setting a virtual space in which a plurality of objects are arranged;
• a virtual camera control process of controlling a virtual camera corresponding to a point-of-view of a user wearing a head mounted display;
• a display process of generating an image as viewed from the virtual camera in the virtual space as a display image on the head mounted display;
• and
• a determination process of determining whether a given change condition is satisfied based on point-of-view change information of the user,
• in the virtual space setting process,
• the processor performs
• arranging an information display object controlled to follow a change in the point-of-view of the user in the virtual space,
• in the determination process,
• the processor performs
• determining that the given change condition is satisfied when a change speed of a line-of-sight direction or a point-of-view position of the user becomes equal to or higher than a given speed, or when a change acceleration of the line-of-sight direction or the point-of-view position of the user becomes equal to or higher than a given acceleration, and
• in the display process,
• the processor performs
• an erase process of the information display object, a semi-transparentization process of the information display object, or a cancel process of following by the information display object to a change in the point-of-view of the user, as a change process of a display mode of the information display object, when determining that the given change condition is satisfied, and
• the processor performs
• a return process of the change process of the display mode of the information display object after the change process of the display mode of the information display object, when it is determined in the determination process that a given return condition is satisfied.
