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.
