Abstract
A mobile device moves by calculating a distance between a sound source and the mobile device using a sound source direction estimation technique. The mobile device moves by a reference distance in a direction perpendicular to a direction in which the mobile device faces the sound source when call sound of the sound source is generated, outputs voice to instruct to the sound source to generate recall sound, checks a directional angle of the mobile device when recall sound is generated by the sound source, calculates the distance between the sound source and the mobile device according to the reference distance and the directional angle of the mobile device, and moves to the vicinity of the sound source.
