Semantic Evaluation Method of Automobile Modeling Based on Event-Related Potential Experiment Absolute Time Marking Method

摘要:

借助Muse脑电设备，采用绝对时间标记法，探索事件相关电位（ERP）实验的造型评价方法，从而缩短造型设计评估周期，提高企业内部造型设计决策效率。首先通过句尾歧义经典实验范式，验证Muse脑电设备可用于ERP的N400经典实验范式研究，其次进行多模态语义加工研究的复合刺激范式实验，验证Muse脑电设备测试结果。结果表明，Muse脑电设备在对汽车造型语义与文字语义进行测量时，能够准确采集N400成分并进行比较。N400成分可以在特定刺激下反映用户的真实想法，提高汽车造型决策效率，降低造型设计成本。

Abstract:

With the help of the Muse EEG device， this paper explores the styling evaluation method of event-related potential experiment （ERP） by using the absolute time notation method to shorten the styling design evaluation cycle and improve the efficiency of internal styling design decision-making in the enterprise. First， through the classic experimental paradigm of sentence ending ambiguity， it is verified that the Muse EEG device can be used for the N400 component research of ERP. Then， the compound stimulation paradigm experiment of multi-modal semantic processing research is performed to verify the test results of the 32-lead EEG device and the Muse EEG device. The results show that the Muse EEG device can effectively collect the N400 EEG data. The N400 amplitudes induced by 32-lead EEG and Muse EEG devices are consistent when measuring the semantics of car modeling and text semantics. It is concluded that N400 can reflect the user’s real and objective thoughts under certain stimuli， which can improve the efficiency of automobile styling decision-making and reduce the cost of styling design.
