摘要:
The invention relates to a method for testing a spatial aptitude anomaly and to a device for carrying out said method. The inventive device comprises an arrangement (1) for fixing a human head, a first transparent screen (2) arranged in a close field of view and a second screen which is visible through the first screen and arranged in the far field of view of a tested person. Said device also comprises means (5, 6) for selectively forming images on the first and second screens and means for recording the motion trajectory of the tested person's pupil watching said images. The inventive method is based on the detection of specific faults of the pupil trajectory such as nystagmus, interception or linearisation of the trajectory, a sudden depression of eyes, etc, when the tested person watches the image displacement along a smooth trajectory on one screen, and on the detection of the irregular modifications of the pupil size and position thereof caused by the reaction to instantaneous transfer of the image from one screen to the other, while the head of the tested persons remains in a fixed position.
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.
