A wearable ergonomic gaze-tracker for infants.

In this paper we present a low-cost hardware and software solution for monitoring gaze and head movements in infants. The proposed device consists in a webcam and a magneto-inertial sensor mounted on a cap. Signal acquisition and elaboration is carried out on a common PC. Technological choices and calibration procedures rely on a minimally obtrusive and ecological approach. The purpose of this work is to present preliminary in-lab evaluations on a new method that may enable researchers to gain new insights on the contents of visual experience from the child's point of view.
