Available in PDF, EPUB and Kindle. Book excerpt: An experiment conducted to compare two methods--graphic and textual-- of indexing reference materials for use of image interpreters in a tactical image interpretation facility is reported. The objective was to evaluate the two methods for speed and accuracy in locating rolls of reference imagery in a TIIF. Image interpreters trained in the use of area-oriented graphic and textual indexes to tactical imagery on roll film were required in two experiments to obtain from indexes the accession number of rolls of imagery containing coverage for a given area. Interpreter performance with both types of indexes was compared for accuracy and speed. Major findings were: (1) Interpreters took less time on the average with the textual index when areas were small; (2) with the graphic index, less time was taken when areas were large. The longer time taken with the textual index to locate desired imagery for large areas appeared due to recording and analyses tasks required under these conditions. Conclusions point to the greater utility of the graphic index in a manual image processing system where coverage of large geographical areas is required or if image coverage has to be precisely defined. The textual index appears more useful in a computerized system where coverage of small area targets with less definition is the major requirement.

Download or read book Study of Two Image Interpreter Map Displays written by Richard S. Laymon and published by . This book was released on 1966 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comparison was made of two methods of displaying reference maps for the use of image interpreters in a tactical image interpretation facility (TIIF). Image interpreters were required to perform two tasks -- to match imagery to a reference map and then to estimate the coordinates of a point on the image. Time taken to reach correct solutions was compared when reference maps were displayed from simulated slide chips (map sections projected onto a fixed screen) and when hard-copy map chips (standard presentation) were used. Measures of performance with both display modes were obtained under experimental conditions where the image would appear on one or two chips. Two conditions of imagery orientation for each map display mode were also imposed: one in which position of the imagery was fixed and one in which the imagery could be freely oriented to the map display. Separate analyses of variance were conducted on time scores from the matching and locating tasks. The following major conclusions were derived: (1) Display of map information upon a screen instead of by hard copy increased time taken by an interpreter to match imagery and to determine map coordinates of an object on an image; the longer time required when the interpreters used map chips was attributable to need to study two slides when the imaged area lay on the boundary of one or both chips. (2) Freedom to orient an image relative to a map display did not affect time taken to complete either the matching or the locating task. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: An experimental study was made to assess the effectiveness of two techniques for rapid screening to select imagery frames of high military potential and to determine the effects of variations in display time on screening performance. Two samples of image interpreters, each consisting of three matched groups, screened three sets of imagery at three different display time intervals (5, 15, and 25 seconds per frame for Sample 1; 10, 20, and 30 seconds per frame for Sample 2). Each interpreter was instructed to perform two screening functions while scanning each print--(1) annotate on the frame all areas of military activity he detected; and (2) assign to each print a priority rating of High, Medium, or Low to indicate estimated intelligence value of the frame. Interpreter performance under the two methods was compared in terms of accuracy and validity of the annotations and priority ratings across the six screening time intervals. Results of the study definitely favored the priority ratings technique over annotation screening. The ratings, of high accuracy even with short viewing time, improved significantly both in accuracy and in validity with longer display time. Generally, performance was better on the measures which were less complex and showed fewer target areas. Validity of the number of annotations on a frame, generally low, did not vary significantly with display time. More incorrect as well as correct annotations were made, a finding similar to previous BESRL findings for unspeeded interpretation performance.

Book excerpt: 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.
