Abstract:
1. A display device comprising: a display unit that displays an image on a display surface; a detection unit that detects, relative to the display surface, a position of an operation element including a magnetic member; and an external force application unit that applies an external force to the operation element via the magnetic member, by generating a magnetic field in a space faced by the display surface, according to the position of the operation element detected by the detection unit and content of the image displayed by the display unit, the external force application unit being arranged on a side opposite to the display surface of the display unit, the display surface emitting a light corresponding to the image, wherein the display unit synthesizes multiple images corresponding to different viewing positions, and displays a synthesized image that causes a virtual object to be viewed stereoscopically so as to appear in the space; the detection unit includes multiple imaging units having different directions of imaging, and detects the position of the operation element in the space relative to the display surface based on an image of the operation element captured by each of the multiple imaging units; and the external force application unit applies the external force to the operation element, the external force being determined on the basis of a comparison between a position of the virtual object in the space and the position of the operation element detected by the detection unit.
