Claim 14:
15. An electronic device comprising:
an eye tracker to track gaze directions of two eyes of a subject;
a memory to store a plurality of object representations of a plurality of objects in 3D space; and
one or more processors to:
determine a gaze endpoint of the subject in the 3D space based on a vergence of the two eyes using the gaze directions of the two eyes in a 3D reference coordinate system detected by the eye tracker;
determine a plurality of respective distances between the gaze endpoint and a plurality of representative points as a plurality of object representations representing a plurality, of locations of a plurality of objects in the 3D space;
determine which object representation of the plurality of object representations the subject is gazing at based on the plurality of distances between the gaze endpoint and the plurality of the object representations; and
identify which object among the plurality of objects the subject is gazing at based on the determined object representation.
