1. Exercise equipment comprising:
an exercise device for causing a user to perform a predetermined exercise which stimulates movement;
a measurement device configured to measure a viewpoint position of the user in a predetermined reference 3-D coordinate system when the user performs the exercise by using the exercise device; and
a video device including a fixed and unworn viewing surface configured to generate, based on the viewpoint position, a display video of a plurality of objects in a virtual space in the reference 3-D coordinate system which simulates how the plurality of objects appear when the plurality of objects are viewed from the viewpoint position via the viewing surface, and allows the user to view images as if moving in the virtual space, and display the display video on the viewing surface, wherein
the virtual space constitutes a three-dimensional video representing the plurality of objects as three-dimensional objects in the virtual space,
the video device modifies a perspective of the plurality of three-dimensional objects in the three-dimensional video as the user moves, based on the measured viewpoint position of the user in the predetermined reference 3-D coordinate system, and
the video device is configured to perform a transformation by which the plurality of objects in the virtual space, which are defined in three-dimensional data, are projected on the viewing surface to generate the display video.
