Research On The Interaction Design Of Supermarket Self-service Cashier Terminal Under The Unconscious Theory

The gradual development of smart new retail and mobile payment has prompted retail enterprises such as supermarkets and convenience stores to introduce and use self-service cashier terminals with low labor costs and high settlement efficiency on a large scale.Commodity transaction is an important part of the entire shopping process,which directly affects the shopping experience of consumers.However,the existing supermarket self-service cashier terminal interface is complicated,and the learning cost is high.It ignores the user’s experience and feelings,especially for users who use this new settlement method for the first time and middle-aged and elderly users who have the problem of "digital divide".In fact,the needs of these users should be more concerned.Guided by the unconscious theory,taking the interactive interface of supermarket self-service cashier terminals as the research object,combined with the current research foundation,this topic explores the method of integrating the concept of Without Thought into the interface design of supermarket self-service cashier terminals.It aims to realize the benign interaction of userterminal-environment.The main research content and research methods of this topic are divided into the following parts:First of all,through the method of literature analysis,this topic summarizes and summarizes the theory of unconsciousness and its research methods.By understanding the current state of cognitive psychology,neuropsychology,human-computer interaction,and unconscious design,it lays the foundation for follow-up research.Secondly,using the case comparison analysis method,this topic deeply analyzes the four common supermarket self-service cashier terminal interfaces in the market from five dimensions:strategy layer,scope layer,structure layer,framework layer and performance layer,and summarizes their characteristics and shortcomings.At the same time,with the help of Shadowing and AEIOU framework,the user’s behavior of commodity settlement in the supermarket selfservice settlement channel is recorded and sorted.In addition,using the contact graph to split user behavior,this topic focuses on listing the problem paths,analyzing and summarizing the interaction problems of the existing terminal interface,so as to derive design opportunities.Thirdly,guided by the unconscious theory,this project proposes three levels of unconscious design,namely,the level of five senses,the level of memory and habit,and the level of cultural background.On this basis,this project builds a model of unconscious design application,that is,objective sketching,scene restoration,and scene reproduction.Finally,using the three levels of Without Thought and the application model of Without Thought,aiming at the interaction problems of existing terminals,combined with user needs,this topic proposes a design scheme from the perspective of Without Thought.Specifically,the practicability of the theoretical model is verified through the design practice of the supermarket self-service cashier terminal interface.At the same time,the design evaluation link of this project is to evaluate the design practice through three indicators of effectiveness,efficiency and user satisfaction.Based on the unconscious theory and the concept of Without Thought,this research topic explores that the supermarket self-service cashier terminal interface can further meet the implicit needs of users on the premise that it has reasonable functions.In this way,a positive interaction between human,machine and environment can be generated,so as to enhance the consumer’s sense of technology shopping experience.
