authoring of augmented reality

There is provided an information processing device including an image acquisition unit configured to acquire an input image of a real space captured with an imaging device, a user interface unit configured to display the input image on a screen of a display device and detect a designated position designated by a user on the screen, a computation unit configured to compute a three-dimensional position of a virtual object in an augmented reality space from the designated position detected by the user interface unit, and an authoring unit configured to associate the three-dimensional position of the virtual object computed by the computation unit with the virtual object to store the three-dimensional position in a storage medium.
