Children with disabilities are frequently ignored by the general population, hence the development of movement evaluation and training devices for use in special education settings are relatively overlooked. Usually the performance of these children is not stable and contains variations. Hence in order to get a complete picture of their sport performance, simply measuring movement time and distance is definitely not representative. With the rising attention from government regarding fitness and social participation of the disabled in recent years, developing a special-designed individual evaluation & training plan is of great importance. To achieve this goal, a device which is able to record the complete process of movement, and contains algorithm that can pick up the movement characteristics of children with disabilities is needed. The purpose of this study is to design and develop a smart soccer ball system for use in children with intellectual disabilities(ID), and to compare the performance between children with ID and the typically developed.

Inclusion Criteria:

1. Intellectual disabilities (ID) group:

   • children with mild to moderate intellectual disabilities.
   • able to walk independently
   • can follow simple commands

2. Typical developed children:

   • age-matched TD children

Exclusion Criteria:

1. fracture or receive orthopedic surgery within six months.
