基于LDA模型和意象图式的产品隐喻设计方法研究

Product Metaphor Design Method Based on LDA Model and Imagery Schema

目的为实现隐喻设计方法的喻体选择和隐喻转译,结合LDA模型和意象图式提出一种新型产品隐喻设计方法。方法应用LDA聚类分析始源域中事件的情绪体验,获取用户在始源域中的主题喻体。基于深度访谈和图式表征分析提取意象图式,并通过AHP评价排序获取重要图式转译因子。将图式因子进行组合表述,联想产品相应功能特征,完成意象喻体到产品主体的转译。结果以减压产品为例进行设计实践,通过LDA聚类获取了感官放松、情感满足、体验良性发展、探索未知、无意识本能、体能释放六大主题与相应模态,以及与主题对应的图示因子,并以可视化桌面蓝牙音箱为设计载体,从视觉、听觉和触觉模态介入,结合图式联想完成了音乐播放、探索互动、自动休眠和情绪释放4个功能隐喻设计。利用加权算法对设计方案进行测试评估,验证了设计方法的合理性。结论从隐喻设计现状出发,探索了基于LDA模型和意象图式的产品隐喻设计方法并加以实践,验证理论与方法的可行性与有效性,为产品隐喻设计乃至其他情感价值类产品的设计研究提供了优质案例与借鉴。

The work aims to propose a novel product metaphor design method by combining the LDA model and im-agery schema,so as to achieve metaphor selection and translation in the design process.Firstly,the emotional experiences of events in the source domain were analyzed using LDA clustering to obtain thematic metaphors of users in that domain.Secondly,imagery schema was extracted through in-depth interviews and schema representation analysis,and important schema translation factors were identified through AHP evaluation and ranking.Finally,these schema factors were com-bined and expressed to associate with corresponding product functional features,to complete the translation from imagery metaphor to product metaphor.The study exemplified this method with stress-relief products,identifying six major themes(sensory relaxation,emotional satisfaction,benign experience development,exploration of the unknown,unconscious in-stinct,and physical release)and corresponding modalities through LDA clustering,along with illustrative factors.Using a visual desktop Bluetooth speaker as the design medium,metaphorical designs for music playback,interactive exploration,automatic sleep,and emotional release were developed through the integration of visual,auditory,and tactile modalities with schema association.Moreover,the design schemes were evaluated using a weighted algorithm,confirming the valid-ity of the method.In conclusion,this study explores and applies a product metaphor design method based on the LDA model and imagery schema,validating its feasibility and effectiveness,and providing valuable examples and insights for the design research of product metaphors and other emotionally valuable products.
