Mobile device and method and computer-readable medium controlling same for using with sound localization
First Claim
1. A method of controlling a mobile device, the method comprising:
- in response to a sound source generating a call sound, moving, by a computer, the mobile device by a reference distance in a direction perpendicular to a direction in which the mobile device faces the sound source;
outputting, by the computer, a voice to instruct the sound source to generate a recall sound when the mobile device has moved the reference distance;
checking, by the computer, a directional angle of the mobile device;
calculating a distance between the mobile device and the sound source according to the reference distance and the directional angle of the mobile device; and
moving the mobile device toward the sound source.

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.

11. A mobile device, comprising:
-
a direction estimator to estimate a directional angle of the mobile device relative to a sound source making a call sound; a traveling direction determination unit to determine a traveling direction using the estimated directional angle; a driving unit to move the mobile device by a reference distance in the traveling direction; a voice output unit to output a voice to instruct the sound source to generate a recall sound when the mobile device has moved the reference distance; and a sound source position calculator to calculate a distance between the sound source and the mobile device according to the reference distance and the directional angle of the mobile device when the directional angle of the mobile device relative to the sound source is estimated according to the recall sound, wherein the traveling direction determination unit determines the traveling direction as a direction perpendicular to the direction in which the mobile device faces the sound source when the call sound is made. - View Dependent Claims (12, 13, 14, 15, 16, 17)
