AR support system for therapy in 3 to 8-year-old children with altered fine motor skills

Abstract

In this project, an augmented reality (AR) system was designed and developed to contribute to therapy in children from ages 3 to 8 who suffer from fine motor skills disorder or seek to improve their skills during their neurodevelopment. The system was designed in the Unity engine along with a Leap Motion sensor so that the kids' hands can interact with scenarios created in the platform. The construction of the system followed the respective phases that describe the cascade methodology for the development of software systems, including the study of requirements and use cases. Additionally, it is intended that the progress of the child is tracked when he/she is performing a set of activities to develop fine motor skills. The Feine Motonik "FeMo" built module, has an 88.9% usability according to the study carried out in this article, which contemplates the test phase with the objective users who describe the situation of disorders in fine motor skills.
