A new SMART fabric concept is reported in which visual changes of the material are designed to influence different human emotions. This is achieved by developing a novel electrochromic composite yarn, knitted into pattern-changing fabrics, which has high response in temperature change and uniform contrast. The influence of these pattern-changing effects on the response of the human visual brain is investigated further by using event-related potential (ERP). Four SMART pattern-changing fabric pairs were used in this experiment. Each fabric presents two patterns interactively with different, but complementary or opposing, pattern attributes. 20 participants took part in the experiment, in which they were exposed to the patterns, while their visual brain activities were recorded. Comparisons of the three prominent ERP components; P1, N1, and P2 that correspond to the two patterns of each fabric have shown significant differences in the latency and amplitude of these components. These differences show that patterns and pattern-changing cause different visual impacts and that these changes influence our level of attention and processing effort. The study concludes that with the pattern changing ability of these thermochromic hybrid materials we can create designs with attributes that can directly manipulate user emotions, which we like to call 'psychotextiles'. Our study also poses much wider questions of our image processing process in relation to design and art.
本文报道了一种新型智能织物概念，该材料的视觉变化旨在影响人类的不同情绪。这是通过开发一种新型电致变色复合纱线来实现的，该纱线编织成可改变图案的织物，对温度变化具有高响应性且对比度均匀。通过使用事件相关电位（ERP）进一步研究了这些图案变化效果对人类视觉大脑反应的影响。本实验使用了四对智能图案变化织物。每块织物以交互方式呈现两种具有不同但互补或相反图案属性的图案。20名参与者参与了该实验，他们在观看图案时，其视觉大脑活动被记录下来。对与每块织物的两种图案相对应的三个主要ERP成分P1、N1和P2进行比较，结果显示这些成分的潜伏期和振幅存在显著差异。这些差异表明图案及其变化会产生不同的视觉影响，并且这些变化会影响我们的注意力水平和处理能力。研究得出结论，利用这些热致变色混合材料的图案变化能力，我们可以创造出具有能够直接操纵用户情绪属性的设计，我们将其称为“心理纺织物”。我们的研究还提出了与设计和艺术相关的关于我们图像处理过程的更广泛问题。
