It is to provide a viewpoint position history management device which can be recovered. A viewpoint position history management device of the present invention stores a light spot projection means, a camera for photographing a projected target surface, a display means for displaying the captured image, and a captured image. Each image has a memory for storing a control program and a control means operated by the control program, and the camera captures a screen including a light spot projected onto the surface to be viewed at desired time intervals.
