METHOD FOR TESTING A SPATIAL APTITUDE ANOMALY AND DEVICE FOR CARRYING OUT SAID METHOD

摘要

There have been developed a method for detecting spatial perception anomalies and a device for carrying out this method. The device comprises an arrangement (1) for fixing the head of a person under test, a first transparent screen (2) disposed in a close-vision field, and a second screen (3) seen through the first one and located in a far-vision field of the person under test. The device is provided with means (5) and (6) for creating images selectively on the first and second screens, and also with a means (4) for recording trajectories of the movement of the eye pupil of the person under test while following these images. The method is based on detecting specific irregularities in trajectories of the eye pupils, such as nystagmuses, cut-offs, sudden drops of the gaze, etc., when the person under test follows the smooth trajectory of a moving image on one of the screens; and also on finding irregular changes in the size and position of the eye pupil in response to instantaneous switching of images between the screens while the head of the person under test is kept stationary. 2 independent claims, 14 dependent claims, 9 illustrations.
