Abstract

La présente invention concerne un système d'affichage d'informations de travail pourvu d'un écran transparent qui affiche, superposées à un champ de vision extérieur, des instructions correspondant au contenu de travail d'un opérateur, l'écran transparent comprenant au moins une unité d'acquisition d'informations biométriques qui acquiert des informations biométriques de l'opérateur au travail. En outre, le système d'affichage d'informations de travail comprend également une unité d'acquisition de données relatives à un travail qui acquiert, en tant que données relatives au travail, des données correspondant à un obstacle au travail lié au travail effectué par l'opérateur, et une unité d'analyse d'informations biométriques qui analyse une corrélation entre les informations biométriques et les données relatives au travail, et définit comme seuil de travail pour chaque opérateur une valeur des informations biométriques à laquelle il est prédit que l'obstacle au travail se produira au moins dans une certaine mesure. Si la valeur des informations biométriques dépasse le seuil de travail, l'affichage transparent affiche une instruction d'aide au travail à l'opérateur.
