An Investigation of the Use of Moire Patterns for Computer-Generated Display Instrument Faces.

Abstract

Moire patterns are 'interference' patterns created when two closely spaced arrays of lines move relative to each other. This study explored a property of moire patterns, namely the 'beat' produced by interference between arrays producing the pattern. This was used to show apparent motion of an indicator dial to supplement or amplify the dial indication. Thus it would be possible to show a change in direction or a trend of an instrument before the motion was apparent on the dial indicator or on a digital indicator. The moire patterns were generated by a set of programs on the computer-generated display on the NAVTRAEQUIPCEN Computer Laboratory IDIIOM (Information Displays Incorporated Input-Output Machine).
