Instrument Reading: the Design of Long-scale Indicators for Speed and Accuracy of Quantitative Readings

Walter F. Grether

Chapter 17 in Psychology and Industrial Productivity, 1981, pp 245-258 from Palgrave Macmillan

Abstract: Abstract Quite a number of instruments used in aviation and elsewhere must be read with precision greater than can be provided by one revolution of a pointer on a circular dial of conventional size. There is considerable accumulated evidence that, except for the direct reading counter, most of the devices that have been used to increase effective scale length result in instruments that are very difficult to read. In a previous study by the author (Grether, 1948a) on the design of clock dials, it was found that as common an instrument as a clock is quite difficult to read. Even the best clock designs required approximately 5 seconds (including recording time) for readings in hours and minutes by Air Force pilots. Even with this time spent on each reading, about 7 per cent of the readings on the better clocks were in error.
