1. A head mounted electronic device comprising:
a body;
a lens clip disposed on the body and including at least one opening defined therein,
an infrared-ray emissive device disposed the body and configured to emit an infrared-ray;
an infrared-ray imaging device disposed on the body, wherein the infrared-ray imaging device is configured to acquire a first eyeball image when the infrared-ray is reflected from an eyeball of a user; and
a processor operatively connected to the infrared-ray emissive device and the infrared-ray imaging device,
wherein the processor is configured to:
transmit a first signal to the lens clip;
determine whether a user lens is inserted into the at least one opening, based on a second signal received in response to the first signal;
upon determination that the user lens is not inserted into the at least one opening, execute an eye tracking algorithm based on the first eyeball image; and
upon determination that the user lens is inserted into the at least one opening, execute the eye tracking algorithm based on a second eyeball image, wherein the second eyeball image is obtained by removing an additional reflected light image resulting from the user lens from the first eyeball image,
wherein the body includes a first electrode and a second electrode facing toward the lens clip, and
wherein the first electrode and the second electrode are electrically connected when the user lens is inserted into the at least one opening.
