Abstract:

In the continuation of research concerned with development of techniques to improve performance of image interpreters, the usefulness of stereoscopic viewing was assessed in terms of quality of information obtained and the rate at which it is extracted. Tactical and strategic photographs were used in developing performance measures which were administered during July and August 1960 to two matched groups of image interpreters at the U. S. Army Intelligence Center. For each measure, stereo pairs were provided to one of the two groups and nonstereo photographs to the other. Analysis of the data obtained established an equivalence of stereo and nonstereo viewing in terms of quality of information provided and confidence assigned by interpreters to their responses. The number of objects reported tended to be higher, under the nonstereo viewing condition. Findings strongly suggest that 1 need for stereo capability should be demonsrated before new display equipment is developed for use of military image interpreters and 2 future studies should examine additional interpreter functions.
