1. An augmented reality content in-situ authoring method, comprising:
selecting an augmented target object to be augmented from a camera preview image of a real world;
recognizing a two-dimensional (2D) plane region based on the augmented target object and then constructing a virtual three-dimensional (3D) space centered on the 2D plane region, wherein the virtual 3D space includes a plurality of 3D cube areas surrounding the recognized 2D plane region;
reconstructing a virtual sub-space including a plurality of sub-cube areas by dividing at least one of the plurality of 3D cube areas;
selecting any one of the plurality of sub-cube areas as an augmented target space, augmenting the augmented target object centered on the augmented target space, rotating the augmented target object to determine an augmented direction, and then registering augmented reality content in a database; and
receiving a selection of an authoring position in the camera preview image through author's gaze tracking and a point using a part of an author's body in the camera preview image,
wherein a size of the virtual 3D space is constructed differently according to at least one of a type and size of the augmented target object,
wherein at least one of a size of the virtual 3D space and a central position of the virtual 3D space is constructed differently based on the selected authoring position,
wherein each of the plurality of 3D cube areas is visually expressed as different visual information based on an author's constraint, which includes at least one of color vision deficiency or color blindness, and
wherein the plurality of 3D cube areas being expressed in different colors excluding color-deficient colors or in different hatching styles.
