Abstract:

The experiment measured the maximum area which can be reached on a flat vertical surface by the two arms of eight male subjects seated at varying viewing distances away from the surface. The paper discusses the influence of some of the variables viewing distance, arm length, and body distance between pivot centers. It was found that each arm described an approximate circle whose diameter decreased as the distance between the subject and the flat vertical surface was increased. The three viewing distances of 10 inches, 15 inches, and 20 inches were selected as representative of actual operating practice.
