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.
Claims20
A controlling method for inputting messages to a computer, by which a practical mouse is needless, and the control function of mouse being formed by a capturing image of a video camera, the method including the following steps:
- (A) capturing an image of a referring background and an object image different with that of the referring background by a video camera;
- (B) capturing a maximum point in Y axis as the A point of a cursor;
- (C) capturing a maximum point in X axis as the B point of a click;
- (D) monitoring movement of pointer A, and
- (E) monitoring a distance between the pointers A and B, and as it is varied to be larger than a set value .sub..DELTA. AB, generating a click selecting function.
