ABSTRACT:
A graphic aid device is disclosed which may be used with computers having a mouse-type computer cursor controller. The device provides a specific geometric orientation to the mouse, thereby enabling a tracing member attached onto or near the mouse to be used to manually trace complex figures while simultaneously and accurately transferring the complex figures to the computer memory. The device of the present invention utilizes a drawing machine arm to maintain a specific geometrical relationship of the mouse with respect to the surface over which the mouse is moved to trace the complex figure.
