The scientific research related to the use of eye tracking technologies are currently of particular relevance. A substantial area of scientific knowledge, in which it is feasible to use eye tracking technologies, is associated with the study of perception of visual information. One of the trends of such research is the examination of the impact of compositional construction of visual image upon its perception by the viewer. The object of this research is elements of graphic composition (stylistic and color solutions). The subject is the methods and algorithms for digital processing of graphic material. The article employs the computational methods of color correction, eye tracking technology, expert assessment, statistical processing of the obtained experimental data. The scientific novelty of this work consists in the development of methodology of preparing and conducting computational experiments for the impact of the stylistic solution of graphic composition upon its perception by the viewer. The technique developed by the authors has proven itself in carrying out the experiments for studying the effect of color solution of the frame upon its perception by the viewer. The study revealed the statistical significance of the impact of stylistic solution of graphic composition upon viewer’s perception. The hypothesis that abstract graphic compositions are difficult for viewer’s perception was statistically proven. The acquired results can be used in constructing complex graphic images, which require the speed of information perception to view them.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
