Research On Product Availability And Morphological Visual Inspection Mechanism Based On ERPs Technology

With the gradual "black box" of high-tech product design,how to correctly and effectively match the user’s intent with the designer’s design intent has become a key issue in current user experience and product form research.This topic is based on the theory of availability and product form semantics,and uses the ERPs experimental technology of human factor engineering to explore the perspectives of product form extensional semantics and connotative semantics and the two types of availability.Recognize the association mechanism.(1)First reviewed the research foundation of availability and the current research status of neurodesign,and expounded the importance of cutting into the research of product shape design from the perspective of availability theory.(2)The analysis of product form semantics is not just a mismatch between the user’s cognitive model and the design model.The essence behind it is that the product’s external form in the real environment focuses on the product’s human-machine relationship and operation mode.The lack of explicit indicative information,and the lack of implicit symbolic information that focuses on emotional factors,is the lack of supply.(3)Summarize the two communication paths of product form semantics,namely,the extensional semantic communication expressing clear human-machine relationship and functional illustration,and the connotative semantic communication covering the emotional,cultural and other characteristics of the product’s intrinsic representation.And find the key factors to reduce the cognitive friction in the two types of semantic communication: Action affordance,which represents the behavioral operation,and Color Affordance,which represents the color emotion.(4)Design and conduct ERPs experiments for action availability and color availability.Experiment 1 explores the evaluation indicators of the use process and experience of different operating attributes of handheld tool products,and Experiment 2 explores the evaluation indicators and cognitive effects of different color elements on the experience of the same type of handheld tool products.(5)Through the extraction and analysis of EEG components,the two experiments found EEG indicators evaluated by the user’s behavior perception and specific action recognition mechanism under the condition of extended semantic communication,and the user’s color Evaluating EEG Factors by the Poetic Mechanism of Perception and Specific Action Through detailed evaluation materials and mastery of control variables,the pertinent conclusions between product semantic transmission and availability were obtained,and new EEG reference indicators were provided for product neuro-design.
