Abstract: Systems, methods, and devices for eye tracking are provided. A device may include a multi-functional optical module including a plurality of optical lens layers. The device may include a layer, among the plurality of optical lens layers, including a patterned substrate including a plurality of light emitting diodes in a field of view of the layer and a plurality of wires configured to connect to a printed circuit board assembly. The light emitting diodes in the field of view may be configured to illuminate light directed to at least one eye of a user to cause at least one reflection of the at least one eye.

Abstract: An eye tracking system with in-optical-assembly plane illumination is described. Side-emitting light emitting diodes (LEDs) aligned with a plane of an optical assembly of a near-eye display device are used to illuminate the eye of a user and generate glints that can be detected by an eye tracking camera. A waveguide display of the near-eye display device projects computer-generated content to the eye. A mirror is positioned between the LEDs and the waveguide display to reflect light beams generated from the LEDs toward the waveguide display to mitigate any double glints that may cause ghost signals. A processor of the near-eye display device determines a position and gaze of the eye based on the captured image of the eye with the glints, and generates the computer-generated content for the waveguide display based on the position and gaze of the eye.

Abstract: An eye tracking system with in-optical-assembly plane illumination is described. Side-emitting light emitting diodes (LEDs) aligned with a plane of an optical assembly of a near-eye display device are used to illuminate the eye of a user and generate glints that can be detected by an eye tracking camera. When a corrective optical lens or similar element is included in the optical assembly that may distort illumination beams from the light emitting diodes (LEDs), the distortion is mitigated by using in-package or externally modified LEDs that provide angled beams. In addition to in-package level mitigations such as reflectors or labels, edge portions of the distorting optical elements may be shaped or complemented with refractive elements to redirect the beams toward the eye.
