Various implementations disclosed herein include electronic devices, systems, and methods that detect reflections of light produced by a plurality of light sources reflected from an eye. An example electronic device may include a frame, an image sensor, a transparent substrate coupled to the frame, a waveguide coupled to the transparent substrate, and a processor coupled to the plurality of IR light sources. The transparent substrate may include a plurality of infrared (IR) light sources that may be configured in a spatial arrangement within the transparent substrate or on a surface of the transparent substrate. The waveguide may be configured to display a projected image. The processor may be configured to receive sensor data from the image sensor. The sensor data may correspond to a plurality of reflections of light produced by the plurality of IR light sources and reflected from an eye.
