A method for a first portable electronic device to locate a second portable electronic device includes: determining location coordinates of the first portable electronic device, receiving location coordinates from the second portable electronic device, determining a relative direction from the first portable electronic device to the second portable electronic device based on a comparison between the location coordinates of the first portable electronic device and the location coordinates of the second portable electronic device, generating an arrow on a display of the first portable electronic device, the arrow representing a direction from the first portable electronic device to the second portable electronic device. Wherein the direction of the arrow is automatically updated based on changes in the location coordinates of the first portable electronic device and the location coordinates of the second portable electronic device.

L'invention concerne une méthode permettant à un premier dispositif électronique portable de localiser un deuxième dispositif électronique portable. La méthode consiste à : déterminer les coordonnées de l'emplacement du premier dispositif électronique portable, recevoir les coordonnées de l'emplacement à partir du deuxième dispositif électronique portable, déterminer la direction relative du premier dispositif électronique portable au deuxième selon une comparaison entre les coordonnées de l'emplacement du premier dispositif électronique portable et celles du deuxième dispositif électronique portable, générer une flèche sur l'écran du premier dispositif électronique portable, la flèche représentant la direction du premier dispositif électronique portable au deuxième. La direction de la flèche est automatiquement mise à jour en fonction des changements des coordonnées de l'emplacement du premier dispositif électronique portable et de celles du deuxième dispositif électronique portable.
