Abstract

Un sistema de seguimiento de cabeza para determinar la orientación de la cabeza de un usuario con respecto a un sistema de coordenadas de referencia (13), que comprende: un elemento de montaje de cabeza, destinado a ser fijado a la cabeza del usuario, y un sistema sensor o de detección destinado a detectar la orientación del elemento de montaje de cabeza con respecto al sistema de referencia (13); caracterizado por la presencia de un señalizador o marca distinguible y de un sensor óptico (10) diseñados para que, durante su uso, se fijen, respectivamente, con respecto a un primer punto conocido, fijo en relación con el elemento de montaje de cabeza, y con respecto a un segundo punto conocido, fijo en relación con el sistema de referencia (13), o viceversa, y de medios de procesamiento (14, 28) destinados a determinar los instantes en que el señalizador se encuentra dentro del campo de visión del sensor óptico (10), y en el cual la salida de los medios de procesamiento (14) se utiliza para corregir la deriva o desviación del sistema sensor, o para proporcionar una verificación independiente de que el sistema está funcionando dentro de las tolerancias previamente seleccionadas.
