Quantifying interaction with robotic toys in pre-term and full-term infants

Area of Science:

• Developmental Pediatrics
• Neuroscience
• Robotics

Background:

• Infants born pre-term face higher risks of developmental, behavioral, and motor delays.
• Early detection and intervention are crucial for improving functional outcomes in at-risk infants.
• Current assessment methods are resource-intensive and may not capture natural infant behavior.

Purpose of the Study:

• To introduce the Play and Neuro Development Assessment (PANDA) Gym, an affordable, sensor-based system for assessing infant behavior.
• To evaluate the PANDA Gym's ability to differentiate between pre-term and full-term infants' motor and visual engagement with robotic toys.
• To explore novel methods for early detection of neurodevelopmental differences.

Main Methods:

• Development of the PANDA Gym, a mechatronic, sensor-based play environment.
• Analysis of video recordings of 24 pre-term and full-term infants interacting with three distinct robotic toys.
• Manual coding of interaction frequencies and durations (e.g., kicking, grasping, gazing) using established classification codes.

Main Results:

• Pre-term infants exhibited similar visual engagement (gazing) with toys as full-term infants.
• Full-term infants demonstrated significantly higher frequency and duration of physical engagement with the robotic toys compared to pre-term infants.
• The PANDA Gym successfully detected behavioral differences between pre-term and full-term infant groups.

Conclusions:

• The PANDA Gym provides a viable, low-cost tool for assessing infant behavior and neurodevelopment outside clinical settings.
• Observed differences in physical engagement may indicate early neurodevelopmental variations in pre-term infants.
• Further research is needed to ascertain if detected differences are attributable to post-conceptional age or developmental delays.
