摘　　要：为解决产品气味嗅觉体验的客观测评,提出了一种基于嗅觉诱发脑电分析的产品材料气味用户嗅觉体验测试方法。分析了产品材料气味嗅觉诱发脑电测试的原理,设计与试制了一种用于嗅觉脑电事件相关电位试验的10通道气味发生器,通过音频信号转换控制信号的关键技术,实现通过心理学试验编程软件E-Prime 2.0对10通道气味发生器的编程与控制。选取薄荷香皂、硫磺香皂与苹果香皂3种不同香型的香皂作为嗅觉诱发脑电试验材料,招募了10名被试对3种气味进行用户嗅觉脑电事件相关电位测试,结果显示薄荷香诱发脑电波P300的波幅显著高于硫磺香皂和苹果香皂的波幅,与被试对3种产品气味的主观评价结果一致,使得产品气味的用户体验评价更加科学可靠。For the sake of the objective evaluation of olfactory experience of product odor,an olfactory-experience test based on the olfactory evoked EEG analysis is worked out.The analysis is conducted on the principle.A 10-channel odor generator is designed and manufactured for the olfactory EEG event-related potential experiment.With the aid of the key technology of audio-signal conversion and control,the 10-channel odor generator is programmed and controlled by means of E-Prime 2.0,which is a psychology-based experimental programming software.With menthol soap,sulfur soap and apple soap taken as examples,10 volunteers are asked to test the olfactory EEG event-related potential of three kinds of odors.The results show that the amplitude of P300 induced by menthol is significantly higher than that of sulfur soap and apple soap,and the results are consistent with those obtained from the subjective evaluation of these three products.It makes the user-experience evaluation of product odor more scientific and reliable.
