A Quick and Simple Portable Automated Scorer for the Farnsworth-Munsell 100-Hue Test

A cheap, portable automated scorer for the Farnsworth-Munsell (FM) 100-hue test has been developed. It consists of a light-pen, a series of omni-directional bar-codes attached to the reverse of the FM 100-hue caps and a small micro-computer. The print-out includes patient details, a linear histogram of the partial errors by cap position, indication of the peak error positions for congenital colour vision deficiencies and appropriate statistical analysis of the total error score. All of the results are available within four minutes of completing the testing procedure.
