A monitor for… the baby monitor?!
This is Sandra Tsing Loh with the Loh Down on Science.
Raising kids is a science – one that we need more data on.
Enter Zhenzhen Weng and team at Stanford. They created HARMONI, an A-I tool that watches videos to study how kids and caregivers interact. It tracks movement, body language, touch, visibility, and conversations. It’s accurate and one hundred times faster than humans at “reading children.”
HARMONI could improve pediatric care, early education, and developmental psychology. By automating video analysis, it could also help in behavioral science and public health. We could gain better insight into how early experiences shape growth and learning.
It’s only a matter of time before HARMONI runs the household! May I have an extra cupcake, HARMONI?
