Air floating video display apparatus

An air floating video display apparatus comprising:

• a video display configured to display a video;
• a retroreflection plate which a light flux from the video display enters;
• an imager;
• and
• a controller,
• wherein the light flux reflected by the retroreflection plate forms an air floating video as a real image,
• wherein the controller can set a virtual position of a 3D model relative to the air floating video as a real image,
• wherein the video display displays a video resulting from a rendering process of 3D data of the 3D model based on a viewpoint position of a user detected from an image captured by the imager and the virtual position of the 3D model, and a video for stereoscopic viewing based on motion parallax for the 3D model is displayed in the air floating video as a real image, and
• wherein the 3D model is a 3D model in which bones of Humanoid format are set, and at the virtual position of the 3D model set by the controller, a start point of the bone of buttocks of the 3D model is arranged at a position shifted relative to a position of the air floating video as a real image, in a direction opposite to a traveling direction of principal ray when the light flux reflected by the retroreflection plate forms the air floating video.
