基于眼动实验的ASD儿童陪伴机器人造型设计评价研究

目的 通过解析ASD儿童视觉偏好特征，提高陪伴机器人造型设计评价的有效性，为设计师及教辅人员提供参考。方法 首先调研整理目前市场上具有代表性的陪伴机器人造型样本，对样本进行灰度模式处理，制作亮度直方图;然后结合文献分析从30余项眼动指标中筛选出10项代表性的眼动指标，并运用眼动追踪方法展开实验，收集整理各项眼动指标数据及视觉偏好得分;接着通过逐步回归法筛选出3项对视觉偏好影响较大的眼动指标;在此基础上建立眼动指标主因子与视觉偏好之间的回归关系，并通过实验再次进行验证。结果 通过实验发现，基本几何形的陪伴机器人造型更为符合ASD儿童的视觉偏好。结论 合理解析并利用ASD儿童陪伴机器人的视觉偏好、眼动指标及造型特征的相关性，可为陪伴机器人造型设计研究提供理论依据。

Research on Modeling Design Evaluation of ASD Children Accompanying Robot based on Eye-Movement Experiment

By analyzing the characteristics of ASD children''s visual preference, the effectiveness of modeling design evaluation of the accompanying robot can be improved, which provides a reference for designers and teaching assistants.First of all, the representative modeling samples of accompanying robots in the market were investigated and sorted out, manipulated in monochromatic processing and made into brightness histogram; Then, according to the literature analysis, 10 representative eye-movement indexes were selected from more than 30 eye-movement indexes, and the experiment was conducted with the eye-movement tracking method with collected data of eye-movement indexes and visual preference score; After that, three eye-movement indexes were selected by the stepwise regression; On this basis, the regression relationship between the main factors of eye-movement index and visual preference was established and verified by experiments.According to the experiment, it is found that the basic geometric shape of the accompanying robot is more consistent with the visual preference of ASD children.By analyzing and utilizing the correlation of visual preference, eye-movement indexes and morphological characteristics of the ASD children accompanying robot, it can provide theoretical basis for the research of the modeling design of the accompanying robot.
