A method for searching out an object in a building or group of buildings stores positions of objects in relation to wireless communication base stations. Relative lateral and vertical positions of an electronic device are calculated according to strengths of wireless signals received by the wireless communication base stations from the electronic device and by reference to sensors. Actual distance between the electronic device and the object is determined to be more or less than a preset distance and orientation is also determined. Information as to an object within the preset distance can be transmitted to the electronic device. A server executing the method is also disclosed.
