Abstract: An apparatus to provide augmented reality includes an image acquisition unit to acquire an image including a target object, a supplementary information acquisition unit to acquire supplementary information, an object recognition unit to recognize the target object from the acquired image, and a candidate nomination unit to generate candidate objects based on the supplementary information. A method for providing augmented reality includes transmitting, at a terminal, an image including a target object or supplementary information of the target object, and location information of the terminal to a server; and determining, at the server, whether the target object is recognized, and generating a list of candidate objects based on the supplementary information, if the target object is not recognized.

Abstract: A terminal device stores augmented reality generated by merging an image of an object and attribute information associated with the object. The terminal device, and a method therefor, allow for retrieval of stored augmented reality information about selected objects if the terminal is no longer at a location where the object's image was captured. The terminal device obtains a preference level for the attribute information and displays the attribute information based on the preference levels. Based on usage of the attribute information, the terminal redetermines preference levels for the attribute information. If previously stored augmented reality is requested, the terminal displays the previously stored augmented reality based on the redetermined preference levels.
