Abstract

Se propone un método para detectar un marcador fiduciario mostrado en un dispositivo (2) de visualización en un mundo real, en donde un dispositivo (1) portátil que comprende una cámara y un unidad de detector de marcador, realiza: la obtención de información de atributo actual representativa de un valor actual de al menos un atributo modificable asociado con el marcador (5) fiduciario mostrado; la detección del marcador fiduciario mostrado en una imagen mostrada en el dispositivo de visualización, de acuerdo con la información de atributo actual; el cálculo de información de postura representativa de una postura del dispositivo portátil en relación con el marcador fiduciario mostrado en el mundo real, de acuerdo con la información de atributo actual y el marcador fiduciario mostrado detectado; y la obtención de la primera información de atributo nueva representativa de un primer valor nuevo de al menos un atributo modificable, el primer valor nuevo depende de la información de postura calculada.
