This paper treats the human factor considerations involved in the Mod II PICTUREPHONE®set development to maximize customer safety and usage efficiency, to provide a functional circuit environment, and to produce a pleasing appearance design. The set was designed to accommodate 99 percent of the American adult population in environments having illuminations varying from 3 to 660 fL. Particular attention was given to the optical problems of juxtaposing video receiving and transmitting facilities. The design incorporates a number of new features including electronic zoom capability for changing the field of view, electronic height control, graphics mode capability, and a silicon target camera tube which is considerably more resistant to damage than previous tubes.
