摘　　要：为解决汽车前脸造型设计决策的问题,比较了用户感知燃油车与电动车前脸造型特征的差异,探讨了汽车前脸正性和负性表情对消费者偏好决策的影响,提出一种采用脑电测量技术评价用户反馈的方法。以Neural Scan脑电仪为数据采集工具,采集了40位用户观看传统汽车与电动车表情并做出是否购买决策的脑电数据,通过事件相关电位分析,发现用户对传统车的情绪感知优于电动车,用户偏好购买正性表情的汽车。回归分析结果发现,P300和LPP两个脑电成分对用户购买决策有显著影响。研究结果表明:电动车车脸设计应加大拟人化效果,脑电测量可作为设计决策的客观依据。In order to solve design and decision-making issue of form features of car front face,the differences between user perception of traditional cars and electric cars’form features of front face were compared.The influences of positive and negative expressions of car front face on consumer preferences decision-making were explored.A method that evaluated user feedback using electroencephalogram(EEG)measurement technology was proposed,the EEG data of watching expressions of traditional cars and electric cars were collected from 40 users neural scan EEG as data acquisition tool to make a decision on whether to purchase or not.Through event-related potential(ERP)analysis,it was found that user emotional perception of traditional cars was better than that of electric cars.Users preferred to purchase cars with positive expressions.The results of regression analysis showed that P300 and LPP had significant impacts on user purchase decisions.The research results showed that the design of electric car front face should enhance the effect of anthropomorphism.EEG measurement could be used as an objective basis for design decision making.
