AI辅助沟通系统助自闭症儿童与家长高效交流
AACessTalk: Fostering Communication between Minimally Verbal Autistic Children and Parents with Contextual Guidance and Card Recommendation
- 通过实时引导与情境卡片推荐，促进亲子对话
- 11组家庭两周使用中对话频率与轮次显著提升
- 帮助家长优化互动策略，增强孩子表达主动性
由于极少说话的自闭症（MVA）儿童主要通过少量词汇和非语言信号与父母交流，父母常难以激发孩子表达细微情绪与需求，也难理解其复杂信号。我们提出AACessTalk，一款基于平板的AI中介沟通系统，旨在促进MVA儿童与父母之间的有意义交流。该系统实时为父母提供互动引导，并向儿童推荐情境相关词汇卡。通过对11组MVA儿童-父母配对进行为期两周的部署研究，我们评估了系统在日常对话练习和相互参与方面的效果。结果显示所有配对均表现出高度参与，对话频率与轮次明显增加。同时，系统促使父母反思自身互动方式，增强了儿童在沟通中的自主性。本文讨论了在亲子互动中设计平衡沟通动态的技术意义。
原文摘要 · Abstract (English)
As minimally verbal autistic (MVA) children communicate with parents through few words and nonverbal cues, parents often struggle to encourage their children to express subtle emotions and needs and to grasp their nuanced signals. We present AACessTalk, a tablet-based, AI-mediated communication system that facilitates meaningful exchanges between an MVA child and a parent. AACessTalk provides real-time guides to the parent to engage the child in conversation and, in turn, recommends contextual vocabulary cards to the child. Through a two-week deployment study with 11 MVA child-parent dyads, we examine how AACessTalk fosters everyday conversation practice and mutual engagement. Our findings show high engagement from all dyads, leading to increased frequency of conversation and turn-taking. AACessTalk also encouraged parents to explore their own interaction strategies and empowered the children to have more agency in communication. We discuss the implications of designing technologies for balanced communication dynamics in parent-MVA child interaction.
