目的 代际合作绘画能有效提升老年人与儿童的情绪和认知收益，但实际操作中存在合作不平衡和松散的问题。基于社会互赖理论，探索在代际合作绘画系统的设计中，绘画内容的互动动画如何提升老年人与儿童之间合作绘画的参与度和合作行为。方法 基于近似刚性变形(As-rigid-as-Possible)和双线性插值算法(Bilinear Interpolation Algorithm)开发代际合作绘画交互式原型，并运用绿野仙踪法(Wizard-of-Oz)模拟AI实现绘画内容的互动动画，增强合作参与度与合作行为深度。采用定量与定性相结合的研究方法，邀请16对儿童和老年人组合进行组内实验。结果 绘画内容的互动动画显著提高了老年人和儿童的绘画参与度，促进了任务导向行为的增加，并在一定程度上减少了合作不平衡现象。结论 本研究证实了互动动画在提升代际合作绘画中的积极作用，为后续代际合作绘画设计奠定基础。

Intergenerational cooperative drawing can effectively enhance the emotional and cognitive gains of the elderly and children, but there are problems of uneven and loose cooperation in practice. Based on social interdependence theory, the work aims to explore how the interactive animation of drawing content can enhance the engagement and cooperative behavior of cooperative drawing between the elderly and children in the design of an intergenerational cooperative drawing system. Based on Approximate Rigid Deformation (As-Rigid-As-Possible) and Bilinear Interpolation Algorithm (Bilinear Interpolation Algorithm), an interactive prototype of intergenerational collaborative drawing was developed, and the Wizard-of-Oz method was used to simulate AI to realize the interactive animation of the drawing content to enhance the participation and depth of the collaborative behavior. A combination of quantitative and qualitative research methods was adopted and 16 dyads of children and the elderly were invited to conduct a within-group experiment. The interactive animation of drawing content significantly increased drawing engagement in both the elderly and children, facilitated an increase in task-oriented behaviors, and reduced cooperative imbalance to some extent. This study confirms the positive role of interactive animation in enhancing intergenerational cooperative drawing and lays the foundation for subsequent intergenerational cooperative drawing design.
