METHOD AND APPARATUS FOR DETERMINING RELATIVE POSITION BETWEEN TWO TERMINAL DEVICES

A method and apparatus for determining a relative position between two terminal devices. The method for determining a relative position between two terminal devices comprises: receiving, by means of two differently located microphones in a first terminal device, a time difference between ultrasonic signals transmitted by a loudspeaker in a second terminal device; and determining, on the basis of a relative position between the two microphones, a relative position between the first terminal device and the second terminal device. The method can be used to determine relative positions between multiple terminal devices without significantly increasing costs. La présente invention concerne un procédé et un appareil destinés à la détermination d'une position relative entre deux dispositifs terminaux. Le procédé destiné à la détermination d'une position relative entre deux dispositifs terminaux consiste : à recevoir, au moyen de deux microphones situés différemment dans un premier dispositif terminal, une différence
