Abstract
A head mounted display (HMD) displays content to a user wearing the HMD, where the content may be based on a facial model of the user. The HMD uses an electronic display to illuminate a portion of the face of the user with. The electronic display emits a pattern of structured light and/or monochromatic light of a given color. A camera assembly captures images of the illuminated portion of the face. A controller processes the captured images to determine depth information or color information of the face of the user. Further, the processed images may be used to update the facial model, for example, which is represented as a virtual avatar and presented to the user in a virtual reality, augmented reality, or mixed reality environment.
