ABSTRACT:
In a method for manipulating a selected object on a computer display of a computer system through the use of a pointing device and a screen based icon, the types of manipulation may include rotating and/or scaling the selected objects. The method includes the step of selecting a manipulating tool having a designated "axle" mark that serves as its center of rotation. The pointing device is directed towards a "handle" portion of the manipulating tool that is spaced apart from the axle to "grab" the handle. The pointing device is then used to rotate the handle about the axle. The computer system then manipulates the selected object by an amount that is a function of the angular distance that the handle is rotated about the axle user interface includes a screen based icon.
