A display control device includes a processor. The processor is configured to: determine content to be superimposed and displayed over an object on a first display unit fixed to a moving body or a second display unit worn on a human body, the object being a real image seen through the first display unit or the second display unit; select either the first display unit or the second display unit to display the content based on a predetermined condition; and superimpose and display the content over the object on the first display unit or the second display unit, the first display unit or the second display unit being selected to display the content.
