Abstract
An apparatus and method for recognizing an indoor zone in which a user is located by using an Earth's magnetic field that is generated naturally instead of the conventional method of combining a magnetic field generator and a magnetic field sensor. The apparatus includes a zone evaluator configured to primarily recognize a location of the portable terminal by using first and second components of an Earth's magnetic field and to finally recognize the location of the portable terminal by using first and second images.
