Abstract: Embodiments of the present disclosure provide a method for identifying an indoor environment location. The method includes an operation of obtaining a visibility map of an indoor environment. The visibility map may include a plurality of static markers in the indoor environment. The method can determine a direction of a first static marker with respect to magnetic north by an electronic device if the electronic device is located to point at the first static marker and can determine a direction of a second static marker with respect to magnetic north if the electronic device is disposed to point at the second static marker. The method can calculate an intersecting point based on the determined first static marker and second static marker and can identify a location of the electronic device in an indoor environment.

Abstract: A method of generating data representing a structure of a room on a device, the method including: outputting an audio signal at a first position in the room; acquiring a first reflection signal of the audio signal at the first position; outputting the audio signal at a second position in the room; acquiring a second reflection signal of the audio signal at the second position; estimating distance information about the room by using the acquired first and second reflection signals; acquiring at least one angle information about the room; and generating a floor plan illustrating the structure of the room using the estimated distance information and the acquired angle information.
