DEVICE FOR MEASURING THE VISUAL ATTENTION OF SUBJECTS FOR A VISIBLE OBJECT |
摘要 |
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.
