Claim:
A hand-held jigsaw, comprising: a saw blade; control means for automating a tracking of an element selected from the group consisting of a saw blade, the hand-held jigsaw, and both along layout lines; a sensor comprising a camera unit configured to use analog image processing to divide a monitoring region into individual search lines and, to detect individual points of layout lines provided on a workpiece; optical mouse sensors for detecting movement and speed data; an actuator unit; a processor unit for receiving and processing sensor information, including movement and speed data, image data and data associated with the detected points and, based on the points, image data, movement and speed data interpolates and adapts an actual path curve or spline, generates control signals and transmits said control signals to the actuator unit for controlling said saw blade speed and movement direction and, by adjustment of a saw blade angle, wherein the saw blade angle represents an angle by which the saw blade is moveable around a longitudinal axis of the saw blade, and wherein said longitudinal axis of said saw blade extends parallel to a main span direction of the saw blade.
