Disclosed herein are a location tracking apparatus and method. The location tracking apparatus includes a head tracking unit, and a pointer tracking unit. The head tracking unit extracts a location, 3DOF and orientation of a head of a user by capturing the user from a screen on which a game is displayed using a first webcam and tracks the user's gaze based on the results of the extraction. The pointer tracking unit tracks a point indicated by a laser pointer projected onto the screen by capturing the screen using a second webcam, and designates the tracked point as cross hairs corresponding to a target to be shot at. The head tracking unit and the pointer tracking unit tracks the user's gaze and the point simultaneously. |
