Socially assistive robots may help the treatment of autism spectrum disorder(ASD), through games using dyadic interactions to train social skills. Existing systems are mainly based on simplified protocols which qualitatively evaluate subject performance. We propose a robotic coaching platform for training social, motor and cognitive capabilities, with two main contributions: (i) using triadic interactions(adult, robot and child), with robotic mirroring, and (ii) providing quantitative performance indicators. The key system features were accurately designed, including type of protocols, feedback systems and evaluation metrics, contemplating the requirements for applications with ASD children. We implemented two protocols, Robot-Master and Adult-Master , where children performed different gestures guided by the robot or the adult respectively, eventually receiving feedback about movement execution. In both, the robot mirrors the subject during the movement. To assess system functionalities, with a homogeneous group of subjects, tests were carried out with 28 healthy subjects; one preliminary acquisition was done with an ASD child. Data analysis was customized to design protocol-specific parameters for movement characterization. Our tests show that robotic mirroring execution depends on the complexity and standardization of movements, as well as on the robot technical features. The feedback system evaluated movement phases and successfully estimated the completion of the exercises. Future work includes improving platform flexibility and adaptability, and clinical trials with ASD children to test the impact of the robotic coach on reducing symptoms. We trust that the proposed quantitative performance indicators extend the current state-of-the-art towards clinical usage of robotic-based coaching systems.

为 ASD 儿童应用的运动、社交和认知技能培训机器人教练的设计

社交辅助机器人可以通过使用二元交互训练社交技能的游戏来帮助治疗自闭症谱系障碍(ASD)。现有系统主要基于对受试者表现进行定性评估的简化协议。我们提出了一个用于训练社交、运动和认知能力的机器人教练平台,有两个主要贡献:(i)使用三元交互(成人、机器人和儿童)、机器人镜像,以及(ii)提供定量的绩效指标。关键系统功能经过准确设计,包括协议类型、反馈系统和评估指标,并考虑了 ASD 儿童应用程序的要求。我们实现了两个协议,机器人大师成人大师 ,儿童分别在机器人或成人的引导下执行不同的手势,最终收到有关运动执行的反馈。在这两种情况下,机器人在运动过程中都会镜像对象。为了评估系统功能,对一组同类受试者进行了测试,其中包括 28 名健康受试者;一项初步收购是对 ASD 儿童进行的。数据分析被定制以设计用于运动表征的特定于协议的参数。我们的测试表明,机器人镜像的执行取决于动作的复杂性和标准化,以及机器人的技术特征。反馈系统评估运动阶段并成功估计练习的完成情况。未来的工作包括提高平台的灵活性和适应性,和 ASD 儿童的临床试验,以测试机器人教练对减轻症状的影响。我们相信,所提出的定量绩效指标将当前最先进的技术扩展到基于机器人的教练系统的临床使用。
