The Eye Tracker!
One way to look at a person’s behaviors is to track there eyes! This non invasive process involves a camera and infrared light, which tracks where the participants eyes are looking on the screen!
How do you test infants with this? We have two main ways to test infants- one is where an infants sit on their parent’s lap and the other is using an adjustable high chair, depending on what works best for the baby!
Does this hurt my eyes? Definitely not! The eye tracker will not bother your eyes!
Another way to test behavior is to have play a game on an iPad. Sometimes they will be asked to play games, make choices, or pick different objects!
