CA 2629656
A method for testing a person's vision is disclosed. The method includes providing, for display to the person, one or more sequences of test images, each test image including one or more test symbols. For each test image, a target symbol is identified to the person. The person then views each test image in the sequence and activates a control in response to recognising a test symbol that replicates the shape of the target symbol. At the completion of the sequence, a parameter value associated with the activations is processed and correlated with a vision metric. A system for testing a person's vision is also disclosed.
L'invention concerne un procédé permettant de contrôler la vision d'une personne. Ledit procédé consiste à fournir, à la personne, un affichage d'une ou de plusieurs séquence(s) d'images de test, chaque image comprenant un ou plusieurs symbole(s). Pour chaque image de test, on identifie un symbole cible pour la personne. Puis, cette personne visualise chaque image de test de la séquence et active une commande en réponse à la reconnaissance d'un symbole test qui reproduit la forme du symbole cible. A la fin de la séquence, on traite une valeur de paramètre associée aux activations et on établit une corrélation avec une métrique visuelle. L'invention concerne également un système permettant de contrôler la vision d'une personne.
