SmarToyGym: Smart Detection of Atypical Toy-oriented Actions in At-risk Infants

Summary

The study aims to develop a SmarToyGym where sensitized, wireless toys are strategically hung and placed within reach of infants to elicit toy-oriented body and arm/hand movements. Each toy will be equipped with sensors capable of measuring the infant's grasping actions such as squeezing, pinching, tilting, etc.

A low-cost 3D motion capture system will be used to collect video data and the infants' reaching and body kinematics in response to the toys. A pressure mat will be used to measure postural changes to detect weight shifts, rolling, crawling and other movements away from the initial posture. By capitalizing on these wireless and low-cost technologies, it will permit the regular and non-invasive monitoring of infants, which can lead to detailed, non-obtrusive, quantitative evaluation of motor development. In this vein, the investigators also aim to conduct proof-of-concept testing of the SmarToyGym with atypical and typical developing infants. The investigators will include infants' ages 3 to 11 months who are categorized as high-risk or low-risk using the Bayley Infant Neurodevelopmental Screener.
