L'appareil (1) peut former une partie de la télécommande (10) ou du dispositif (20) ou peut se situer entre les deux. Au moins deux capteurs différents (11, 12) utilisés en combinaison dans la télécommande (10) offrent un avantage considérable. L'appareil (1) peut effectuer la combinaison en utilisant les informations du second capteur pour vérifier, compléter, corriger et/ou annuler les informations du premier capteur. Le premier capteur (11) peut comprendre une caméra, le second capteur peut comprendre un détecteur pour détecter une accélération, un mouvement, un angle, une inclinaison, une orientation et/ou une rotation.
