Eureka Baby! Baby and Mobile (IMAGE) Florida Atlantic University Caption A 3D reconstruction/representation of the positions of the infant's joints (red = left side; green = right side; yellow/orange = center; and the mobile's position = blue). The image to the right depicts little silver spheres placed on the baby's skin at different joints. Special cameras send out infrared light, which bounces off the spheres and reflects back to the cameras. The system then takes that reflective infrared information from all the cameras and figures out the exact location of each sphere.
