摘　　要：目的为了探究一种更高效的苗绣纹样检索方式,通过对手绘草图检索及文本检索过程中的认知负荷来进行对比研究。方法首先通过构建认知负荷信息检索过程模型,对5个认知阶段的平均认知负荷及所需时间进行实验对比;其次通过眼动指标(持续注视时间、眼球扫视振幅、眼球直径)及NASA-TLX评估对两种检索过程的认知负荷进行分析;最后基于眼动追踪得到可视化眼动数据(热点图、注视轨迹)验证是否符合检索任务需求。结论基于手绘草图的图形检索方式更适合于苗绣纹样检索,通过主、客观融合对比实验验证了草图检索的高效性,同时也验证了眼动追踪和NASA_TLX具有相关性,能更有效地进行认知负荷测量。The work aims to explore a more efficient way of retrieving Miao embroidery patterns by conducting a comparative study on the cognitive load during hand-drawn sketch retrieval and text-based retrieval processes.A cognitive load information retrieval model was constructed to experimentally compare the average cognitive load and required time across five cognitive stages.Eye-tracking metrics(such as dwell time,saccade amplitude,and pupil diameter)and NASA-TLX evaluations were employed to analyze the cognitive load of the two retrieval processes.Finally,visual eye-tracking data(heatmap and gaze path)were obtained to validate whether they met the requirements of the retrieval task.The graph retrieval method based on hand-drawn sketches is found to be more suitable for Miao embroidery pattern retrieval.The efficiency of sketch retrieval is validated through subjective and objective integrated comparative experi-ments.Additionally,the correlation between eye-tracking and NASA-TLX is confirmed,making them more effective for measuring cognitiveload.
