In order to measure the visual attention of persons or animals to a visible object, a beam (9) is radiated to an area of observation (1) including the persons or animals under test. A measuring arrangement in close vicinity to the object comprises a radiation source (1) emitting, e.g. an invisible parallel beam (9), a scanning member (3), guiding said radiation beam (9) across the area of observation (1) and detector means (6, 7) receiving the radiation scattered from the area of observation (1). Radiation from the retina and/or cornea of said persons or animals is selectively detected and transformed into an evaluation signal.
Afin de mesurer l'attention visuelle que des personnes ou des animaux accordent à un objet visible, un faisceau (9) est émis vers une zone d'observation (1) comprenant les personnes ou les animaux soumis au test. Un système de mesure, situé à proximité de l'objet, comprend une source de rayonnements qui va émettre un faisceau parallèle invisible (9), par exemple, un élément de balayage optique qui va guider le faisceau (9) à travers la zone d'observation (1), ainsi qu'un système de détection (6, 7) qui va recevoir les rayonnements dispersés depuis ladite zone d'observation (1). Les rayonnements provenant de la rétine et/ou de la cornée des personnes ou des animaux sont ensuite mesurés de manière sélective, puis transformés en un signal d'évaluation.
