Abstract: The present invention includes the steps of: displaying an unlocking interface via a user interrupt; receiving an unlocking pattern inputted via the unlocking interface; detecting the received unlocking pattern and executing a mode corresponding to the detected unlocking pattern to thereby measure the status degree of an object corresponding to the detected unlocking pattern; and calling a lookup table in which a range of adequate status degrees for each type is measured and matched according to a pre-set and classified object type to thereby determine the status degree of the measured object, and feeding back the result of the determination via the unlocking interface.

Abstract: Provided is a method of providing an augmented reality interaction service, the method including: generating reference coordinates based on a 3-dimensional (3D) image including depth information obtained through a camera; segmenting a region corresponding to a pre-set object from the 3D image including the depth information obtained through the camera, based on depth information of the pre-set object and color space conversion; segmenting a sub-object having a motion component from the pre-set object in the segmented region, and detecting a feature point by modeling the sub-object and a palm region linked to the sub-object based on a pre-set algorithm; and controlling a 3D object for use of an augmented reality service by estimating a posture of the sub-object based on joint information of the pre-set object provided through a certain user interface (UI).

Abstract: The present invention relates to a technology that allows a user to manipulate a virtual three-dimensional (3D) object with his or her bare hand in a wearable augmented reality (AR) environment, and more particularly, to a technology that is capable of detecting 3D positions of a pair of cameras mounted on a wearable display and a 3D position of a user's hand in a space by using distance input data of an RGB-Depth (RGB-D) camera, without separate hand and camera tracking devices installed in the space (environment) and enabling a user's bare hand interaction based on the detected 3D positions.
