Abstract

Selon cette invention portant sur la communication à distance, un utilisateur (500) situé à un emplacement (502) a accès en temps réel à des informations saisies au niveau d'un emplacement (503) éloigné. En combinant des capacités de vidéoconférence et un casque vidéo unique, des ouvriers sur leur lieu de travail peuvent communiquer et collaborer directement avec des centres et des usines d'assistance. Selon une réalisation, cette invention permet au personnel (521) d'assister à distance des ouvriers (500) sur leur lieu de travail en dirigeant facilement des procédures complexes puisque ce personnel (521) a la capacité de voir et d'entendre exactement ce que les ouvriers (500) expérimentent sur leur lieu de travail. Cette invention permet de plus d'assurer l'entretien d'urgence et préventif en temps réel à des coûts bien moins élevés que dans une démarche traditionnelle.
