Abstract
A method for constructing a gesture mouse utilizes an object e.g., a user's palm) in the background of the photographed region of a video camera as a determination basis. In a computer system, (1) for the image of an object, the point with maximum Y-axis value is set to be a cursor; (2) the point with maximum X-axis value is set to be a push button; (3) the cursor and the push button are used as centers to set small tracking areas respectively; (4) if the distance between the cursor and the push button becomes greater than a designated threshold within a time period, an action of the push button is determined to occur. Images obtained by the video camera are input into a computer through the digital image interface of the video camera or an analog/digital converting card for further processing.
