A disclosed technique relates to an interface capable of registering a context of interest (COI) in an augmented reality environment and, more specifically, to an augmented reality interface technique capable of specifying various types of objects of interest in the real space varied dynamically and adding and intuitively presenting virtual guidance/information associated therewith without physical constraints. The interface according to an embodiment of the disclosed technique can overcome the constraints of an augmented reality marker learned and defined previously to register a three-dimensional object of interest in an augmented reality space according to an immediate situation and can also provide an information representing technique in which augmented guide information provided when registering a three-dimensional object of interest varied dynamically according to work steps.
