Abstract
This study is devoted to the study of systematic errors in visual perception caused by the influence of geometric illusions. The purpose of the work is to identify patterns of distortions in visual perception and to develop new methodological and automated tools for analyzing this phenomenon. The study examines the vertical-horizontal illusion and the illusion of distance between the edges of objects, which allows for a deeper understanding of the mechanisms and systematic errors that occur in the process of visual information processing. As part of the work, new modules were integrated into the previously developed testing system for more accurate measurement of perception and analysis of visual illusions. The results obtained are significant for further research in the field of psychophysics and cognitive psychology, as well as for practical applications in the field of design and development of visual interfaces.
