Fifteen knobs representing types which might be used underwater were subjected to an experimental comparison to determine what types most enhance speed or accuracy of knob adjustment. Six U.S. Navy divers adjusted the knobs underwater while wearing diving gloves in a variety of temperatures, pressures, and diving equipment. Adjustments were made with emphasis on speed or accuracy at each of three positions on the divers. Results indicate that large diameter knobs can be adjusted underwater more rapidly and accurately than smaller knobs, and that some types of tactile markers enhance accuracy of knob adjustment underwater.
