Offenbarung der ErfindungDisclosure of the invention
Die Erfindung geht aus von einem Verfahren und einer Vorrichtung zur Bestimmung einer die Pupillenreaktionsfähigkeit repräsentierenden Größe, wobei die Pupillenreaktion durch ein Lichtereignis hervorgerufen wird.The invention is based on a method and a device for determining a variable representing the pupil reactivity, the pupil reaction being caused by a light event.
Der Kern der Erfindung besteht darin, dass das Lichtereignis nicht zum eigentlichen Zweck des Verfahrens stattfindet, sondern zufälliger Natur sein kann.The essence of the invention is that the light event does not take place for the actual purpose of the process, but may be of a random nature.
Hintergrund der Erfindung ist es, ohnehin vorhandene Lichtereignisse für die Bestimmung der Pupillenreaktionsfähigkeit zu verwenden, um auf diese Weise erfindungsgemäß die Belastung der Pupille durch zusätzliche, eigens zum Zweck des Verfahrens hervorgerufene Lichtreizungen zu vermeiden.Background of the invention is to use existing light events for the determination of the pupil responsiveness, so as to avoid in this way, the burden of the pupil by additional, specifically for the purpose of the method caused light irritation.
Vorzugsweise wird das nicht zum eigentlichen Zweck des Verfahrens stattfindende Lichtereignis mittels eines Lichtsensors, insbesondere einer Kamera festgestellt.Preferably, the light event not taking place for the actual purpose of the method is detected by means of a light sensor, in particular a camera.
In einer vorteilhaften Ausgestaltung geschieht die Bestimmung der die Pupillenreaktionsfähigkeit repräsentierenden Größe in Abhängigkeit von der Zeitdauer zwischen zwei Pupillenzuständen.In an advantageous embodiment, the determination of the size representing the pupil responsiveness occurs as a function of the time duration between two pupil states.
Einer weiteren vorzugsweisen Ausgestaltung gemäß wird die Bestimmung der die Pupillenreaktionsfähigkeit repräsentierenden Größe in Abhängigkeit des Pupillendurchmessers vorgenommen.According to another preferred embodiment, the determination of the variable representing the pupil responsiveness is made as a function of the pupil diameter.
Gemäß einer Ausgestaltung geschieht die Bestimmung der die Pupillenreaktionsfähigkeit repräsentierenden Größe vorteilhaft in Abhängigkeit des Vergleichs der Reaktion verschiedener Pupillen desselben Lebewesens.According to one embodiment, the determination of the variable representing the pupil responsiveness advantageously takes place as a function of the comparison of the reaction of different pupils of the same living being.
Hintergrund dieser vorteilhaften Ausgestaltung ist, dass Lebewesen in der Regel zwecks räumlicher Wahrnehmung mit wenigstens zwei Augen ausgestattet sind, wobei jedes funktionierende Auge über mindestens eine Pupille verfügt.Background of this advantageous embodiment is that living beings are usually equipped for the purpose of spatial perception with at least two eyes, each functioning eye has at least one pupil.
Vorzugsweise wird zur Bestimmung der die Pupillenreaktionsfähigkeit repräsentierenden Größe ein Sensor verwendet. Dabei handelt es sich bei dem Sensor vorteilhaft um eine Kamera und/oder um einen Ultraschallsensor und/oder um einen Radar und/oder um einen Laser.Preferably, a sensor is used to determine the size representing the pupil responsiveness. In this case, the sensor is advantageously a camera and / or an ultrasound sensor and / or a radar and / or a laser.
Zur Unterstützung der Bestimmung der die Pupillenreaktionsfähigkeit repräsentierenden Größe wird vorzugsweise eine Beleuchtungseinheit verwendet. Hintergrund dieser Ausgestaltung ist es, auch in solchen Fällen eine Untersuchung der Pupille durchführen zu können, in denen die Pupille schlecht beleuchtet ist (beispielsweise bei Nacht-, Untertage-, Wald- oder Tunnelfahrten) oder verdunkelt ist (beispielsweise bei der Verwendung von Lichtschutzbrillen oder getönten Brillengläsern).To assist in determining the size representing the pupil responsiveness, a lighting unit is preferably used. Background of this embodiment is to be able to perform an examination of the pupil in such cases, in which the pupil is poorly lit (for example, at night, underground, forest or tunnel rides) or darkened (for example, when using goggles or tinted spectacle lenses).
Gemäß einer vorteilhaften Ausgestaltung wird eine Vorrichtung zur Bestimmung einer die Pupillenreaktionsfähigkeit repräsentierenden Größe verwendet, wobei die Pupillenreaktion durch ein Lichtereignis hervorgerufen wird und das Lichtereignis nicht zum eigentlichen Zweck des Verfahrens stattfindet.According to an advantageous embodiment, an apparatus is used for determining a variable representing the pupil reactivity, wherein the pupil reaction is caused by a light event and the light event does not take place for the actual purpose of the method.
