Development of an Augmented Reality Handwashing Tool for Children with Autism Spectrum Disorder

This paper introduces an innovative Augmented Reality (AR) handwashing tool for children with Autism Spectrum Disorder (ASD). Traditional handwashing training often needs more practical engagement, resulting in adequate muscle memory development. Traditional methods may need to address these children’s needs more effectively, leading to suboptimal handwashing or avoidance. This study presents an Augmented Reality (AR) handwashing tool, leveraging the Microsoft HoloLens2 platform, to offer an engaging learning experience tailored for children with ASD. The tool simulates a bathroom setting, guiding users through handwashing steps using dialogues, text, and audio. Evaluations included observations, interviews, and a controlled experiment involving five children with ASD. Feedback highlighted the tool’s engaging nature, mitigating tactile sensitivities and anxiety linked to regular handwashing. Results showed improved handwashing practices after using the AR tool. This AR approach can foster better hand hygiene in children with ASD. Future research will focus on personalizing the tool, studying long-term engagement, and combining therapeutic strategies to enhance its effectiveness and applicability in enhancing life skills for children with ASD.
