ABSTRACT:
In a method for direct manipulation of images on a computer monitor using a mouse, the image is divided on the monitor into nine regions. Dependent on the region in which a mouse cursor is located, a different function is executed by moving the mouse cursor. In the four corner regions of the image, displacement of the mouse cursor causes an enlargement or downsizing of the image dependent on the mouse displacement. If the mouse cursor is located in the central region, displacement of the cursor results in a shift of the image. If the mouse cursor is located in one of four middle edge regions, respectively disposed between the corner regions, a scrolling of the image ensues dependent on the mouse cursor displacement. In order to activate the function in each region, activation is accomplished by depressing a mouse key.
