Abstract: A facial tracking device including an illuminator and a photon detector. The illuminator configured to project a light toward a first portion of a head of a user and the photon detector configured to detect light reflected from a second portion of the head of the user. The facial tracking device further including a processor that is connected to the illuminator and photon detector and configured to cause the illuminator to project the light toward the head of the user, receive information from the photon detector, and determine a facial expression of the user.

Abstract: A camera module includes an image sensor, a lens assembly, a printed circuit board, and a substrate. The image sensor has edges that define a two-dimensional footprint substantially parallel to a surface of the image sensor. The lens assembly is coupled to a top surface of the image sensor and focuses light onto the top surface of the image sensor. Edges of the lens assembly do not extend beyond the footprint. The printed circuit board is below the image sensor and controls the image sensor. The substrate is coupled to a bottom surface of the image sensor and to a top surface of the printed circuit board. The substrate electrically couples the image sensor to the printed circuit board. Edges of the substrate do not extend beyond the footprint.
