May 10 2024Indiana University What do infants see? What do they look at? The answers to these questions are very different for the youngest babies than they are for older infants, children and adults. Characterized by a few high-contrast edges in simple patterns, these early scenes also contain the very materials needed to build a strong foundation for human vision.

"You can buy 'baby flash cards' for newborns that show these simple, high-contrast images," she explains. "What the head-camera videos show, what this work shows, is that young infants find these types of images all around them in their daily life, just by looking at things like lights and ceiling corners."

"The massive scale of daily-life input" To identify the properties of visual input in infants at approximately three to 13 months old, the researchers placed head-mounted video cameras on 10 infants and 10 of their adult caregivers, collecting and analyzing 70 hours of visual documentation of at-home daily life.

Bigger pictures, past and future Smith and her collaborators have also shown that the same sequence of images improves the training of AI visual systems.
