Abstract:
An electronic device capable of determining an eye convergence angle using a magnetometer sensor is provided. The magnetometer sensor is capable of reporting angle readings in three dimensions that is aligned with an eye gaze direction of each eye of a user. The magnetometer which is incorporated into the device can fit into a human eye like a contact lens and determine the angle of the gaze direction of both eyes with respect to an object within a field of view. By obtaining this eye convergence angle for an object, it is possible to accurately detect depth information. The electronic device also functions as a digital contact lens that can automatically adjust the focal point of the object to provide the user with a clear vision. The electronic device also includes a display that provides the user with additional information about the object.
