Research On Evaluating Methods Of Eye Tracking For Cognitive Performance Of Digital Interface Color Coding

In the context of advanced digital technology increasingly penetrating into various industries,the digital interface of complex systems has become an important part of information weaponry.The problem of digital interface design has been widely concerned by scholars at home and abroad.As an important influencing factor of human visual cognition,color plays a large visual cognition role in the process of complex information transmission.Taking the human-computer interaction demand as the guide and the digital interface cognitive efficiency as the research purpose,through the combination of theoretical research and experimental exploration,the evaluation method of digital interface color coding design is proposed,which provides optimization and improvement for digital interface design and provides theoretical experimental support.Cognitive characteristics and other characteristics of digital interface color are analyzed and studied,and the methods and principles of color coding design are summarized.Combining with the cognitive characteristics of color coding in digital interface,the cognitive mapping relationship between color and information is established,and the cognitive evaluation latitude of color coding is constructed.Eye movement tracking technology is used to evaluate the color coding of digital interface in this paper.Based on the proposed cognitive evaluation latitude,take the HUD of fighter aircraft as an example to conduct design experiment and evaluation experiment on its color coding.Finally the key eye movement indicators that can reflect the cognitive efficiency is explored,and obtained the HUD optimal color coding scheme under different geographical environments,day and night conditions,and brightness conditions.
