STUDIES IN DISPLAY SYMBOL LEGIBILITY. PART XIV. THE LEGIBILITY OF MILITARY MAP SYMBOLS ON TELEVISION
Abstract
The speed and accuracy with which five subjects identified military map symbols were determined with five different resolutions in lines per symbol height on a television monitor in three experiments. The first two experiments indicated that the minimum acceptable resolution is approximately 17 lines even after considerable practice. The third experiment indicated that a slightly lower resolution is permissible only with an optimum contrast of detail and a carefully selected and maintained television system. Recommendations are made for field installations.
