Research On The Relationship Between Background Image And Subconscious Cognition And Its Application In Interaction Design

With the development of social science and the improvement of information technology,the proportion of electronic products and smart products that participate in people’s daily lives has gradually increased,and the frequency of human-computer interaction has increased.With the advent of the experience economy,product user experience has become a strong competitiveness in the market.User experience design is the core of interaction design.Continuously tapping the needs of users has become the key to designer innovation.Most of the existing design methods focus on the needs of the user’s consciousness,but research shows that about 95% of cognition,behavior,and decision-making depend on the needs of the user’s subconscious level.Therefore,paying attention to and exploring the implicit needs of the user’s subconscious level can be used as a kind of design innovative ideas and methods.Vision is one of the main sensory channels for users to obtain information.The image information obtained by vision often establishes the user’s first impression of the product,and even determines the use of the product.Most of the existing theoretical researches are based on single elements of foreground images,such as graphics and colors,while ignoring the composition of background image elements.Based on the theory of visual subconscious cognition,this paper decomposes background images,studies the influence of background image information on user subconscious cognition,and obtains experimental data through design experiments and questionnaire surveys,and obtains objective and rational experimental results.Based on this,a background image design method based on subconscious cognition is summarized,and it is applied to actual design cases,and the effectiveness and feasibility of the method are verified through usability test.(1)Based on the analysis of the subconscious cognition mechanism and the background image and user cognition,the relationship between the two is summarized:First,the background image and user cognition,the subconscious cognition theory,user memory mechanism and the subconscious cognitive mechanism are studied through literature research.Based on this,the relationship between the background image elements and the visual subconscious cognitive mechanism is summarized,laying a theoretical foundation for subsequent research(2)Through design experiments,the relationship between the background image information and the subconscious cognitive mechanism is studied: the element arrangement direction of the background image is the entry point,and the experimental independent variable is the arrangement direction of the lines in the background image.Three sets of experiments are designed to carry out the experimental data.One-way analysis of variance,analysis of data processing results to draw conclusions,verified the experimental hypothesis-the arrangement direction of elements in the background image will have a potential impact on user cognition.In addition,visual perception will affect the results of subconscious cognition,so choose another component in the background image information-the warmth and coldness of colors,and study the relationship between the coolness and warmth of the background image information and the user’s visual perception through questionnaire surveys.The introduction of the concept of "emotion" in the research enriches the subconscious cognitive mechanism of background images.Based on the above research results,a background image design guidance model based on the visual subconscious cognitive mechanism is summarized.(3)The actual design case verifies the effectiveness of the experimental and theoretical research results of this article: According to the guidance model,the product design guidance method with user experience as the core is summarized,aiming to design by tapping the potential needs of users to improve the target user experience.The design method was applied to the intelligent service robot design project,the whole process design of the product interactive experience was completed,and the background image design guidance model and method based on visual subconscious cognition was completed,the product-related advertising design was completed,and the usability test was passed.The research in this article expands the ideas and methods of enhancing user cognition through image design;the background image design method and product interaction design process based on subconscious cognition summarized can be used as a reference for designers in actual work,and innovative Improve the user experience of the product.
