| description | An augmented reality system determines the position and orientation of an eye. The system includes an electronic contact lens that projects images onto a user's retina. The contact lens includes magnetic sensors. The magnetic sensors detect magnetic fields along one axis, or more than one axis, depending on their configuration. The sensors may be a conductive coil, a solenoid, or a tunneling magnetoresistance device. The sensors detect magnetic fields generated by magnetic sources. The magnetic sources may be collocated, or non-collocated, on a wearable device, a device in the environment, or a secondary electronic device. The sources may have different orientations such that they produce magnetic fields along different axes, and the sensors are configured to independently detect the magnetic fields. The system determines the pose of the eye using a combination of the measurements, and the position and orientation of the sensors and sources. |
