Abstract: A relatively low-cost, portable, stand-alone visual training system interactively displays two dimensional representations of elongated objects on a viewing screen. An operator observes the elongated object and through an input device, such as an alpha numeric keyboard, divides the object into segments and allocates the segments according to preselected criteria. The results of the operator's decision are then calculated in a programmed data processor and compared visually with a predetermined result which is stored in memory for the particular object.
