基于 PCCS 色彩体系的 ASD 儿童干预 APP 配色研究

为提升自闭症谱系障碍(ASD)儿童干预 APP 的康复效果，为设计师提供合理有效的参考，提出 一种基于 PCCS 色彩体系的 ASD 儿童干预 APP 界面配色评价方法。首先通过文献分析和焦点小组法，构建基 于 PCCS 色彩体系的 ASD 儿童干预 APP 界面配色评价体系；其次运用 AHP 法获取各项评价指标的权重；再 次筛选得到 8 个基于 PCCS 色彩体系的界面配色设计方案，邀请专家对其打分，得到初始评判矩阵；然后通过 TOPSIS 法获得各方案的排序结果；最后对结果进行解析。研究表明，ASD 儿童对绿色、蓝色等冷色调及明度、 纯度较高的色彩具有较高的认可度；在 PCCS 色调图中，ASD 儿童更喜爱轻柔色调、浅色调、邻近色与互补色 的搭配；在界面配色设计中应更趋于明快、清晰、和谐、稳重的色彩搭配。将该评价方法应用于干预 APP 界 面配色实验方案评价中，可以提高设计评价过程中的客观性、科学性，为设计师进行决策提供参考，更好地促 进 ASD 儿童干预 APP 的发展。

Color matching study of ASD children intervention APP based on PCCS color system

In order to enhance the rehabilitation effect of intervention APP for autism spectrum disorder (ASD) children, and shed reasonable and effective light on the designers, this paper proposed an interface color matching evaluation method for ASD children intervention APP based on the system of PCCS (practical color coordinate system) color. Firstly, the literature analysis and focus group methods were used to construct the interface color matching evaluation system of ASD children intervention APP based on the PCCS color system. Secondly, the AHP method was used to obtain the weight of each evaluation index. Then eight interface color design schemes were selected based on the PCCS color system, experts were invited to offer their scores, and the initial judgment matrix was obtained. Then the ranking results of each scheme were obtained through the TOPSIS method. Finally, the results were analyzed. The results showed that ASD children were more likely to recognize green, blue, and other cool colors, as well as colors with higher lightness and purity. In the PCCS tonal figure, ASD children would prefer gentle tone, light color tone, the collocations of adjacent colors and complementary colors. In the interface color design, the color collocation should  be livelier, clear, harmonious, and stable. The evaluation method was applied to the evaluation of interface color matching experiments for intervention APP, and could boost the scientificity and objectivity in the process of design evaluation, and provide a reference for designers to make decisions, thus advancing the development of intervention APP for ASD children.
