Investigation of the Influence of Geometry, Colour, and Spatial Components on Visual Perception and Their Importance in Visual Design

Abstract

Visual perception and cognitive psychology have focused on visual illusions to understand the visual system. Although much research has been done, the relative impact of geometric forms, color contrast, and spatial depth in visual illusions remains unexamined. This is important as it affects applications like art design, virtual reality, and human-computer interaction. Current research lacks a comprehensive comparison of these factors and their interaction in creating visual illusions. The purpose of this study is to fill this knowledge gap. A set of visual stimuli was designed to systematically study the influence of geometric forms, color contrast, and spatial depth on visual illusions. An experiment was carried out with 180 participants. The effects of different geometric shapes, color contrast levels, and spatial depth cues were evaluated, and subjective evaluations from the volunteers were collected. T-test analysis was used to analyze the experimental data. The t-test analysis of the experimental data showed that color contrast has the most significant effect on visual illusions, followed by geometric forms, while the effect of spatial depth did not reach statistical significance. The results answer the question about the comparative influence of the factors and challenge the traditional dominance of geometric shapes in creating illusions. Based on Treisman's feature integration hypothesis and Gregory's theory of perceptual hypotheses, color's strong influence is due to its perceptual precedence, and geometric forms use more complex cognitive mechanisms. Strong color contrast can lead the visual system's cognitive assumptions astray, enhancing the illusion experience. This study fills the research gap and provides theoretical and practical guidance for improving art design, advancing the field of visual perception research.
