title: A comparison of two 7 x 9 matrix alphanumeric designs for TV displays.
abstract: Twelve technical workers and 16 pilots read individual characters of two alphanumeric designs from a TV screen. Characters were arranged to appear briefly on the screen at a fixed position and contrast level. The comparisons showed an RAE design to give rise to significantly fewer errors than a comparable US design, for the conditions of the experiments reported.
