Visual Search Times for Navy Tactical Information Displays.
Abstract
An experiment was conducted to determine the time and accuracy with which an operator could find target items in each of six preformatted information displays. The displays corresponded to two versions (long and short) of three CRT formats proposed for the Naval Tactical Data System (NTDS). The number of items on the displays ranged from 6 to 40. Operators were tasked to retain either a two- or four-consonant letter set in memory during the search task. Following a fixed time to perform the search, single letter probes were presented to determine that the memory set had been maintained. Total amount of information on the display was the only relevant factor of those examined. Future effort should be concentrated on different search requirements, scan patterns, display area segregation, and practice or operator skill level.
