Abstract

An example electronic device calibrates a center of a sensor for acquiring sensing data differently according whether the electronic device is worn on a part of a user body or not, and provides data sensed based on a result of the calibrating to the user, so that more exact and/or accurate data and a better sense of use can be provided to the user.
