1. An augmented reality display device comprising:
a camera configured to capture a background image;
a distance sensor configured to measure a distance to a real object in the background image captured by the camera;
a display configured to display an image;
a memory configured to store data of the real object and of an AR object;
a controller configured to:
extract a contour of the real object,
determine an area for placing the AR object within the contour of the real object,
display the area for placing the AR object,
receive a selection operation indicating a location for placing the AR object within the area for placing the AR object,
determine a first side of the AR object,
determine a first side of the real object,
associate the AR object with the real object, wherein the first side of the virtual object abuts the first side of the real object,
display the AR object at the location for placing the AR object superimposed on top of the real object in the background image based on a shooting direction of the camera,
calculate a new shooting direction of the camera, and
display the AR object at the location for placing the AR object superimposed on top of the real object in the background image based on the new shooting direction of the camera.
