Abstract
An example method for determining, at an electronic device, a presence or absence of the electronic device in a specific space may include estimating a current location based on strength of signals received from a plurality of wireless communication devices; correcting the estimated location by using movement information acquired through a sensor to generate a first corrected location; correcting the first corrected location by using information about a boundary area of a predefined presence determination area to generate a second corrected location; and determining the presence or absence in the presence determination area, based on the second corrected location.
