Learning to perform self-care skills can pose a major challenge for children with Autism Spectrum Disorder (ASD) as well as the parents and caregivers who support them. The computerized device described in this paper has been used by children with ASD and their carers to autonomously assist with self-care activities. The device uses computer vision and artificial intelligence to track a child with ASD through an activity and issues audio and visual prompts as required. A pilot study involving five children with ASD was conducted to evaluate the efficacy of the device as it assisted with hand washing. Results showed that the device responded correctly to approximately 74% of the situations it encountered. While there are areas requiring improvement, acceptance of the device by children and their parents was encouraging. Efforts are underway to refine the device before evaluation through future long-term, in-home trials. (Contains 6 tables and 5 figures.)
