Abstract
A head-mounted extended reality (XR) display device includes a rigid mounting element coupled to a frame. The XR display device further includes right-side and left-side visible light cameras coupled to the rigid mounting element, right-side and left-side near-infrared (NIR) cameras coupled to the rigid mounting element, and an NIR light-emitting diode (LED) configured to illuminate a region within a field of view of the NIR cameras. The visible light cameras are configured to capture stereoscopic visible light images within a field of view of the user when the user is wearing the frame, and the NIR cameras are configured to capture stereoscopic NIR images within the field of view of the user when the user is wearing the frame.
