註釋Under monitorship of the MAN-COMPUTER FUNCTIONS Task, personnel of the System Development Corporation and the U.S. Army Behavioral Science Research Laboratory jointly conducted a study to evaluate three computer-compatible methods of identifying the image interpretation reference keys most pertinent to a given identification problem. Thirty-two enlisted image interpreters having training experience with imagery showing foreign terrain and targets were subjects for the study. Simulated computer procedures were devised in which the interpreters selected target signatures appearing on checklists as a means of designating the target category and finally the key or keys desired. Results of the experiment showed: (1) Target identification by means of a reference key was as fast and as accurate with computer-compatible procedures of key selection as with the manual procedure; (2) Interpreters tended to base selection of a key on only one or two signatures even when use of additional signatures would have increased probability of valid key selection; (3) Interpreters preferred viewing more than one key before final identification of a target; (4) No significant differences in speed and accuracy of identification were found under any of the procedures when using the two levels of imagery quality.
