Abstract: A calibration system includes a head mounted device including an eye tracking (ET) system, processing logic coupled to the ET camera, and a calibration apparatus removably coupled to the head mounted device. The ET camera may take an image of a plurality of 3D objects on the calibration apparatus to collect calibration information and use the calibration information to update eye tracking parameters for the ET camera. The calibration apparatus may include a plurality of 3D pillars or cylinders having varying heights and which are located at varying distances from each other.

Abstract: An eye-tracking system may include an optical assembly with integrated micro light emitting diodes. The optical assembly may include a substrate and a flexible printed circuit board assembly bonded to the substrate. Micro light emitting diodes may also be bonded to the substrate. A plurality of conductors may be laminated in the substrate. The conductors may electrically connect the micro light emitting diodes to the printed circuit board assembly. An optically clear adhesive layer may be adhered to the substrate. The optically clear adhesive layer may include an anti-reflective layer and an optical adhesive layer to arranged in a stacked configuration.
