ABSTRACT:
A controlling method for inputting messages to a computer, in which by the object, such as a hand, on the background of the capturing section of a video camera, the following parameters is set up within a computer: (1) the maximum Y point of the image of the object is assumed as a cursor, (2) the maximum X point is assumed as a click; (3) small monitoring sections are set up around the coordinate points of the cursor and click, relatively; and (4) if the distance variation between the set cursor and click points is over a allowing value, then it is judged the click has been operated. The digital image capturing by the video camera is directly transferred to a driving means or is transferred through an analog I digital signal converter to a computer for being calculated and controlled as a mouse.
