Virtual reality simulator and virtual reality simulation program

A non-transitory computer-readable recording medium on which a virtual reality simulation program is recorded,

• the virtual reality simulation program being configured to, when executed by a computer, cause the computer to execute:
• a process of acquiring information on a real user position that is a position of a head of a user in a real space;
• a process of acquiring information on a virtual user position that is a position in a virtual space corresponding to the real user position;
• an imaging process that acquires a virtual space image by imaging the virtual space by using a camera placed at the virtual user position in the virtual space, based on virtual space configuration information indicating a configuration of the virtual space;
• and
• a process of projecting or displaying the virtual space image on a screen that is installed at a position distant from the user in the real space and does not integrally move with the user, wherein
• the imaging process includes a perspective adjustment process that adjusts a focal length of the camera such that perspective corresponding to a distance between the real user position and the screen is cancelled.
