INFLUENCE OF COLOR OF THE IMAGE-TEST BACKGROUND ON THE TIME OF DETECTION BY THE HUMAN-OPERATOR OF THE OBJECT LOCATED ON IT, IN COMPUTER TRAINING SYSTEMS

Abstract

The paper presents the results of an experimental study regarding the influence on the recognition time of an object of a given color, from the background color on which this object is randomly localized. The following factors were taken into account: background orientation, object localization sector, area of the site with the object, color of this area, and the complexity of the recognition itself. Eight young students agreed to take part in the experiment. The working hypothesis was whether the recognition time depends on the color of the background area on which the object of attention is located. The object of attention was a light gray image of the plane. The research results are presented in the tables of values of expert estimates of factors and diagrams of the scope – box plot diagrams. The homogeneity of the psychophysical characteristics of the recipients is represented by the result of cluster analysis using as signs of indicators of individual time series, multiple regression equations. The organization of the experiment was to provide the recipient on the monitor of a computer simulator sequence of test images with the appropriate characteristics. The analysis of the results showed that despite the differences in individual psychophysical characteristics, background-color influences the time of recognition of the object of attention. In general, the study showed that, despite some simplicity and primitiveness of the test image, we could confidently accept the assumption of the influence of background color on the time of search and detection of objects of attention. As the sets of scale diagrams show, each recipient perceives the color differently, and in this case, for some background colors, the difference between the recipients is quite small.
