Eye tracking metrics and their interpretation.

In order to objectively assess the effectiveness of rural space design on the affective dimension, this study utilized eye-tracking and electrocardiogram (ECG) monitoring techniques to quantify users’ visual attention and emotional responses and to assess the impact of rural design on users’ affective experience. The results show that incorporating natural elements and cultural features into the design enhances the values of the subjects’ pupil diameter change rate, Heart Rate Variability Index (HRV), subjective evaluation and reduces their Saccade Velocity Average. The experimental results not only verify the application value of eye tracking and ECG monitoring techniques in assessing the design effect of rural space, but also provide a scientific assessment method based on the user’s physiological and emotional responses, thus providing a strong support for the optimization of rural space design.

为客观评估乡村空间设计在情感维度上的应用效果，本研究采用眼动追踪与心电图（electrocardiogram, ECG）监测技术，量化用户的视觉注意力与情绪反应，以此分析乡村设计对用户情感体验的影响。研究结果表明，在乡村空间设计中融入自然元素与文化特色，可提升受试者的瞳孔直径变化率、心率变异性指数（Heart Rate Variability Index, HRV）及主观评价得分，同时降低其平均扫视速度。本次实验结果不仅验证了眼动追踪与ECG监测技术在评估乡村空间设计效果中的应用价值，还提供了一套基于用户生理与情绪反应的科学评估方法，可为乡村空间设计的优化提供有力支撑。
