1. A method, comprising:
positioning first and second triaxial magnetometers respectfully in front of a first eye and a second eye to synchronize respective movements of the first and second triaxial magnetometers with respective movements of a center of the first eye and a center of the second eye, wherein first and second eye gaze direction vectors extend from the centers of the first and second eye, respectively;
each of the first and second triaxial magnetometers detecting a direction of a magnetic field, having X-axis, Y-axis, and Z-axis components, from the first and second triaxial magnetometers, respectively, to an object within a field of view of the first and second eyes, wherein the X-axis, Y-axis, and Z-axis are orthogonal to each other;
determining the first and second eye gaze direction vectors based on the X-axis, Y-axis, Z-axis components detected by the first and second triaxial magnetometers, respectively; and
calculating an eye convergence angle of the object based on the first and second eye gaze direction vectors.
