Legibility of Alphanumerics at Naval Aircraft Crew Stations. II. The Effect of Font Styles and Type of Instruction on Reading Speed.

摘要

This experiment is the second of a series concerned with legibility of aircraft instruments and label legends. In the present experiment the effect of two types of instruction and four font styles on 'Absorption Time' is reported. Under one set of instructions ('Never Asked' type) the subject read two digit numbers and reported only when he had finished reading. In the other set ('How Often' type), prior to each stimulus slide, S was provided a target number and at the end of his reading was asked how often the target number appeared.
