Methods and systems for interacting with an augmented reality application includes a providing an array of barometric pressure sensors within a housing of a wearable device to capture pressure variances detected from motion of one or more facial features that are proximate to the array of barometric pressure sensors. The pressure variances are analyzed to identify motion metrics related to the motion of the facial features. The motion metrics are used to derive engagement metrics of the user to content of the augmented reality application presented to the user.
