Abstract

Dans un mode de réalisation, l'invention concerne un dispositif électronique pouvant vérifier si un accessoire de couverture couplé au dispositif électronique peut aider à déterminer si une fonction cible est fournie ou non, selon qu'une fonction cible du dispositif électronique est activée ou non. Le dispositif électronique selon l'invention peut demander à l'accessoire de couverture une indication d'une image prédéterminée correspondant à la fonction cible, en fonction d'un signal de réponse de l'accessoire de couverture à la vérification, et transmettre un signal pour reconnaître le dispositif cible auquel la fonction cible est fournie. Ainsi, le dispositif électronique peut exécuter la fonction cible sur le dispositif cible en fonction de la réponse du dispositif cible reconnu par le signal de reconnaissance du dispositif cible.
