基于情绪体验的ASD儿童干预机器人造型研究

目的 为提升ASD儿童干预机器人的训练效果,为教辅人员、设计师等提供参考,提出以ASD儿童情绪体验特点为基础的干预机器人拟人化造型特征评价方法。方法 对市场上的机器人造型样本进行拟人度评分,并从中选取代表性样本;从20余项HRV指标中筛选出8项代表性指标,通过HRV实验收集数据;使用改进的PAD情绪量表获取ASD儿童情绪体验主观得分;通过逐步回归法筛选出对情绪体验得分影响较大的HRV指标;以HRV指标为自变量、情绪体验得分为因变量,建立回归关系,为ASD儿童干预机器人造型的设计和方案评价提供理论依据。结果 研究表明,几何型机器人往往带来“放松的”情绪体验,类人型机器人会带来“高兴的”情绪体验,而真人型机器人则可能带来“焦虑的”情绪体验。同时,ASD儿童的愉悦度、唤醒度、优势度与HRV指标之间存在一定的相关性。结论 将改进的PAD情绪量表应用于ASD儿童干预机器人的造型评价中,建立情绪体验和HRV指标之间的回归模型,为设计和评估适合ASD儿童的机器人提供了理论依据,更好地促进了ASD儿童干预机器人的发展。

Modeling of Intervention Robot for Children with ASD Based on Emotional Experience

The work aims to propose an evaluation method of anthropomorphic modeling characteristics of intervention robots based on the emotional experience characteristics of children with ASD to improve the training effect of intervention robots for children with ASD and to provide reference for designers and teaching assistants. Firstly, the anthropomorphism scores of the robot modeling samples in the market were used to select representative samples. Secondly, eight representative indicators were selected from more than 20 HRV indicators and data were collected through HRV experiments. Again, the improved PAD emotion scale was used to obtain the subjective scores of the emotional experience of children with ASD. Then, the HRV that had a greater influence on the emotional experience scores were selected through stepwise regression method principal factors. Finally, the regression relationship between the principal factors of HRV indicators and emotional experience scores was established to provide a theoretical basis for the design and program evaluation of intervention robot modeling for children with ASD. The study showed that geometric robots tended to bring about "relaxed" emotional experiences, humanoid robots brought about "happy, dependent" emotional experiences, and life-like robots might bring about "anxious, dependent" emotional experiences. At the same time, there was a correlation between the pleasantness, arousal, and dominance of children with ASD and the HRV index. Applying the improved PAD emotion scale to the stylistic evaluation of intervention robots for children with ASD and establishing a regression model between emotional experience and HRV indexes provide a theoretical basis for designing and evaluating suitable robots for children with ASD and better promote the development of intervention robots for children with ASD.
