"The early intervention of children with development delay is more effective if it is applied in the golden period of 0-6 years old therefore to greatly reduce the longterm burden of society. In the process of intervention, the most important two issues are accurate functional assessment and abounding functional training. However, the rural areas are not able to meet the above needs due to the lack of therapist and the difficulty to gain rehabilitation equipment. The main purpose of the study is to solve the pain points of early intervention at rural area through the innovation and integration of technologies. It intends to provide adequate solutions to the urgent need of early intervention at rural area following innovation on the interdisciplinary application. First of all, an interdisciplinary team with experts in fields of special education, clinical medicine, physical therapy, occupational therapy, and technology is formed. Next, Routines-Based Interview (RBI) program has been implemented to achieve family-centered home/community early intervention. Then, an Internet of Things (IoT) platform is built to provide real-time video streaming and data visualization capabilities in order to carry out remote assessment. Also, electronic prescription function is implemented to achieve tele-rehabilitation. Finally, the proposed system will be applied to field test to verify its effectiveness and provide service."
