Abstract
A method and apparatus for producing a video display that is especially useful in an article handling system to help control a mechanical arm to move an article into a selected position. A video camera is operated to produce a picture of the article on a video screen. At the same time, force sensor are used to measure forces on the article, and a graphical display of those sensed forces is produced on the view of the article on the video screen.
