An evaluation was made of the separate screening of aerial photos prior to interpretation as a technique for improving performance in the quick-time extraction of information from imagery under varying conditions of frame overlap and image quality. Rolls of positive transparencies were interpreted by 48 interpreters under two conditions: In one condition, the photos had been screened by experienced interpreters; in the other, interpreters used normal Hot Report techniques combining frame selection and target identification in one process. Zero overlap and 50 percent overlap and two levels of image quality were represented in the imagery. On the first trial, half the subjects interpreted preselected imagery, half used regular techniques; on the second trial, procedures were reversed for the two groups. Interpreter performance was evaluated in terms of screening efficiency, accuracy and completeness of interpretation, time and rate of interpretation, and errors. The separate screening procedure added significantly to interpretation time. Overlapping imagery added significantly to interpretation time without increasing accuracy or completeness. The slight difference in image quality introduced did not seriously affect processing time. Accuracy of both screening and interpretation was lower with the lower quality imagery. Screening was more seriously affected than was interpretation. On the basis of evidence, screening cannot be recommended as a useful procedure in rapid interpretation. (Author).

BESRL Technical Research Reports are publications describing completed research studies or programs which contribute directly to the solution of Army human factors problems. The Report is generally divided into two parts--a brief general report to management and a technical supplement. BESRL Technical Research Notes are of interest primarily to technically trained research workers in the Department of Defense and in other government research agencies. Notes present technical information concerning research methodology or basic psychological knowledge growing out of the work program. BESRL Research Studies are special reports to military management, generally prepared in response to questions raised by operating agencies when early answers are needed. Research Studies may include presentations to military management, interim bases for changes in personnel operations, and bases for research decisions. Distribution is usually limited to operating agencies with a direct interest in the content. BESRL Research Memorandums are informal reports on technical research problems. Research Memorandums include the following types of content: details concerning construction of experimental instruments, fragmentary or incidental data, and methodological developments relating primarily to in-house technical operations. Limited distribution is made, primarily to personnel engaged in research for the U.S. Army Behavioral Science Research Laboratory.

Support Systems Research Division and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1969 with Information display systems categories.

The Surveillance Systems research program of the U.S. Army Behavioral Science Research Laboratory has as its objective the production of scientific data bearing on the extraction of information from surveillance displays and the efficient storage, retrieval, and transmission of this information within an advanced computerized image interpretation facility. The present technical research report summarizes in integrated fashion the major problem areas, the rationale of BESRL's approach to their solution, and the general course of research studies completed or in progress in the surveillance areas of manned systems experimentation. The research effort is conducted within the following Work Units: (1) Interpreter Techniques--The determination of interpreter techniques in a surveillance facility; (2) Image Interpretation Displays--Influence of displays on image interpreter performance; (3) Intelligence Systems--Intelligence information processing systems; (4) Image Systems--Information processing in advanced image interpretation systems. Studies of the Surveillance Systems research programs conducted by the Support Systems Research Division of BESRL have resulted in findings which are applicable in optimizing human component performance in existing systems and in providing systems developers with information useful in design specifications for future systems.
