A display system includes a display device and a remote terminal device. The display device includes an image shooting device, an image recognizer, and a display controller. The image recognizer recognizes real objects in an image shot by the image shooting device, and recognizes positions of the recognized real objects on space coordinates. The display controller superimposes a virtual object at a designated position on the space coordinates in the shot image. The image recognizer recognizes a gesture of the real object at the designated position of the virtual object in the shot image. The display controller executes image processing on the virtual object in response to the recognized gesture.
