摘　　要：目的产品外观是用户与产品设计者之间的桥梁,传统情感测量方法很难准确的获取用户情感数据,而脑电技术具有高时间分辨率的优势,为产品外观情感测量提供一种可能。方法从用户脑认知角度出发,以加湿器为研究对象进行用户的情感测量,通过ERPs各成分波幅的差异反映用户的情感变化,进而探索用户的情感加工过程。实验中要求被试对不同的加湿器进行情感偏好(喜欢、不喜欢、中性)判断,同时记录被试的脑电信号反应。结果分析结果显示,N1波、P2波和LPP能够反应用户的情感变化。结论在产品开发设计的早期阶段,通过事件相关电位技术测量用户对不同产品原型的情感偏好水平,从而获取在外观上相对更符合用户需求的产品,为整体用户体验的提升奠定基础。Objective The product appearance acts as a bridge between users and designers. It~ a challenge that using traditional methods to measure users＂ emotions elicited by product appearance. The advantage of electroencepha- lography technology is high - time solution, and it offers a possibility for users＂ affective measurement. Methods The humidifiers were chosen as the experiment stimuli. Users＂ different emotional preferences evoked by the appearance of products were measured by event - related potentials. During the experiment, participants were required to judge whether the presented humidifier was he （she） liked or not through the mouse button clicking. At the same time, EEG signals were recorded. Results The results showed that N1 ,P2 and LPP were three indexes which reflected users＇e- motions. Conclusion In the early stages of product development, ERPs can be used to measure users＇affective pref- erence level to the product prototypes. According to the affective measurement, we can roughly found the products well satisfy users＂ needs, furthermore, improve overall user experience.
