A gesture recognition based user interaction method and apparatus therefor are disclosed. The user interaction device for this is. A face detection unit for detecting at least one user''s face area from the color image photographed by the image photographing apparatus using the face pattern information, a three-dimensional position information of the face and the hand based on the three- A hand region localization unit for selecting a hand candidate region of a predetermined size at both ends of the hand region and selecting a hand region according to the shape of the hand candidate region, A fingertip point extracting unit for calculating a curvature of a pixel existing in a hand-held palm of the hand, and for detecting a fingertip point in accordance with the calculated curvature, and a finger end point extracting unit for extracting at least two of the detected hand regions, And a gesture recognition unit for recognizing the texture. Therefore, the bare hands of a user without special equipment can be detected / tracked based on color information and depth information.
