Abstract

La présente invention se rapporte au domaine technique des dispositifs d'écoute portables. L'invention concerne un procédé d'interaction de casque d'écoute à champ lointain, destiné à être utilisé dans la mise en œuvre d'une fonction d'interaction de champ lointain d'une paire d'écouteurs sans fil. Le procédé comprend les étapes suivantes : lorsqu'un accessoire d'interaction en champ lointain d'écouteur détecte un événement prédéfini déclenchant une fonction d'interaction de champ lointain, celui-ci reçoit des informations de réponse transmises par des premiers écouteurs sans fil connectés à un terminal, les informations de réponse étant un message de réponse produit en transmettant des informations d'instruction vocale captées par un microphone dans les écouteurs sans fil au terminal et reçues en provenance du terminal ayant traité les informations d'instruction vocale; et les informations de réponse sont délivrées. Le procédé utilise les écouteurs sans fil en tant que pont entre l'accessoire d'interaction de casque d'écoute à champ lointain et le terminal, et met en œuvre un échange de données entre l'accessoire de casque d'écoute à champ lointain et le terminal, mettant ainsi en œuvre la fonction d'interaction de champ lointain des écouteurs sans fil. L'invention concerne également l'accessoire d'interaction de casque d'écoute à champ lointain, les écouteurs sans fil, et un support de stockage lisible par ordinateur, fournissant l'effet bénéfique décrit.
