Mixed reality device, processing method, and storage medium

A processing method executed by a mixed reality device including a display and an imaging device, the processing method comprising:

• displaying a virtual space to overlap a real space;
• when the imaging device captures a prescribed object in a real space, recognizing the prescribed object;
• setting an origin of the virtual space and an orientation of a three-dimensional coordinate system that is fixed to the prescribed object based on a pose of the recognized prescribed object;
• acquiring a display position of a virtual object that is pre-registered as coordinates in the three-dimensional coordinate system;
• calculating, using the pre-registered coordinates based on the origin and the orientation, a display position at which the virtual object is to be displayed;
• determining whether or not the display position is present inside a visible region set in front of the mixed reality device;
• and
• displaying a guide indicating a direction of the display position when the display position is not present inside the visible region.
