Baby FaceReader™ can automatically measure facial expressions in infants ranging in age from 6 to 24 months old. Because infants are unable to provide verbal feedback, their facial expressions are particularly insightful.
Baby Facial Action Coding System (Baby FACS)
Infant faces are different from adult faces in that they are smaller, rounder, have a considerable amount of subcutaneous fat, elastic skin and often have little to no eyebrows. Therefore, Baby FaceReader uses the Baby Facial Action Coding System (Baby FACS) to describe specific movements of an infant's face.
Baby FaceReader is ideally suited to research changes and stabilities in infants' facial expressions, as well as responses to taste, odor, and other sensory stimuli. In addition, Baby FaceReader can help analyze cognitive information processing, expressive behavior occurring in naturalistic and experimental situations, and during parent-child interactions.
Detecting risk for developmental disorders
Baby FaceReader has been developed as a state of the art system to automatically detect infant facial expressions in order to help address questions in developmental psychology related to affect and developmental disorders such as Autism Spectrum Disorder (ASD) and attention-deficit hyperactivity disorder (ADHD). Quantifying infants' facial expressions can assist studies in parent-child interaction and shed light on how we can possibly achieve early detection of these developmental disorders.
In this recording, you can see the capturing of valence, and Action Units, with the use of Baby FACS.
Infant responses to food
Is your infant's food sweet or sour? Baby FaceReader has the answer - it makes it possible to identify infants' responses to tastes. For example, the taste of something sweet will result in a facial relaxation, indicating that the infant experienced the sweet taste as pleasant. In contrast, a non-sweet taste will involve certain facial muscle actions indicating an unpleasant experience.
Action Units, as shown in the picture, provide an objective way of describing facial movement in order to answer research questions.
Baby FaceReader is unobtrusive
Measuring infant facial expressions using Baby FaceReader is unobtrusive and will capture a positive or negative valence, a set of Action Units, and head orientation. The Remote Photo-plethysmography (RPPG) module is available as an add-on as well.
