Title:
STUDIES OF DISPLAY SYMBOL LEGIBILITY. PART XV. RELATIVE LEGIBILITY OF LEROY AND TELETYPEWRITER SYMBOLS

Abstract:
The first two studies are reported from a planned series of studies to obtain legibility data on teletyped hourly sequence weather reports. In the first study, subjects were asked to identify symbols, shown singly in a random order with the symbols occurring with equal frequencies. The two teletype fonts, Murray and Long Gothic, were compared with a standard Leroy font. The second study used the teletype fonts only, and the subjects identified symbols shown with symbol frequencies similar to those in typical hourly sequence reports. For these experimental conditions, the teletype fonts were not as legible as the standard Leroy font although the symbol frequencies found in typical hourly sequence reports improved the subjects reading performances.
