An information model of the data structure and an experimental technique for improving the human-computer graphical interface

Abstract

In the article, the authors describe the developed and tested methodology for conducting a computational experiment to study the effect of color solutions on the visual perception of a video frame by the viewer. The developed technique is designed to assess the subjective emotional reaction of the viewer that occurs at the final stage of the human visual system when perceiving visual information. The article describes methods of preparation of stimulus material, methods of conducting an experiment using a developed software module located on a network resource. The authors have developed a methodology for conducting an experiment with online testing, the information structure of the database, a questionnaire for collecting information, the form of testing by the subjects, algorithms for statistical processing of the results of the experiment. This study is based on the results of a series of experiments conducted using a software and hardware complex for fixing oculomotor activity - an eye tracker, which allows obtaining objective parametric data of a template for viewing stimulus material. The technique described in the article is an addition to the experimental study using the eytracking technology. The results of the experiment should be used in the development of textbooks on color correction, as well as in the design of control interface elements. The methodology is programmatically implemented and tested in the local network of Peter the Great St. Petersburg Polytechnic University. It is planned to finalize the Internet survey module and conduct a global experiment with subsequent statistical processing of the results.
