Disclosed is a head mounted electronic device including a body, a lens clip having at least one opening defined therein, wherein the lens clip is disposed on the body so as to face toward a face of a user, an infrared-ray emissive device disposed on one portion of the body, an infrared-ray imaging device disposed on an opposite portion of the body to one portion thereof, wherein the infrared-ray imaging device acquires a first eyeball image obtained when infrared-ray emitting from the infrared-ray emissive device is reflected from an eyeball of the user, and a processor operatively connected to the infrared-ray emissive device and the infrared-ray imaging device.

Aspects of the present disclosure relate to multi-spectrum visual object recognition. A first image corresponding to visible light and a second image corresponding to invisible light with respect to an object can be obtained. A first contour of the object can be identified based on the first image. A second contour of the object can be identified based on the second image. The first contour of the object and the second contour of the object can be integrated to generate a multi-spectrum contour of the object. The object can be recognized using the multi-spectrum contour of the object.
