Apparatus and method for remote control using camera-based virtual touch

A remote control apparatus using a camera-based virtual touch, comprising:

• position calculator, obtaining a 2D image of an user's body by a camera and calculating coordinate data indicating positions of first coordinates and second coordinates of the user's body based on the 2D image of the user's body,
• a matching identifier, determining whether the position of the second coordinates of the user's body matches a valid area with respect to the position of the first coordinates of the user's body based on the calculated coordinate data, and
• a virtual touch setting unit, detecting a variation in the obtained coordinate data of the first and second coordinates to detect the user's motion in response to determination that the position of the second coordinates of the user's body matches a valid area with respect to the position of the first coordinates of the user's body, generating a control command signal for controlling or selecting a particular icon displayed on an electronic device based on the detected motion, and sending the control command signal to the electronic device,
• wherein the calculated coordinate data is 2D data and is coordinate data at a position viewed from lens of the camera, and
• wherein the particular icon to be selected or controlled is determined based on the relation between an angle specified by positions of the first coordinates and the second coordinates on the 2D image and an angle specified by positions of the camera and the particular icon on the electronic device.
