Description
System zur Umweltsteuerung mit bloßer Hilfe des menschlichen Auges.System for controlling the environment using only the human eye.
Die heutige Technik kennt die Umweltsteuerung, die Steuerung von elektrischen Geräten über einen zentralen Punkt, meist ein Computer, in verschiedenen Variationen, Sie wird beispielsweise dazu eingesetzt, Behinderten die Integration in ein uneingeschränktes Leben zu erleichtern. Diese Steuerung, die auch mit diesem System ermöglicht wird, wird verschiedenartig angesprochen, beispielsweise über Spracherkennung oder einfache Schalter.Today's technology is familiar with environmental control, the control of electrical devices via a central point, usually a computer, in various variations. It is used, for example, to make it easier for disabled people to integrate into an unrestricted life. This control, which is also made possible by this system, is addressed in various ways, for example via voice recognition or simple switches.
Diese Arten von Umweltsteuerung sind allerdings für vielerlei Einsatzgebiete nicht geeignet. Kommandos für mehrere Geräte ließen sich mit bloßem Angucken und Lidschlag schneller absetzen als über umständliche Sprachcodes.However, these types of environmental control are not suitable for many applications. Commands for several devices can be issued more quickly by simply looking at them and blinking an eye than by using complicated voice codes.
Wird das Aufnahmegerät, welches das Auge einsieht, mit Hilfe des Lichtleiterkabels konstruiert, so entsteht ein leichtes Gerät, das den Benutzer nicht wesentlich in seiner Beweglichkeit einschränkt Die drahtlose Übertragung der Kameradaten an den Computer trägt dazu bei. Der Benutzer kann sich also durch den Raum bewegen und an die entsprechenden, in die Umweltsteuerung integrierten Geräte, Befehle schnell und leicht per Lidschlag absetzen.If the recording device that the eye sees is constructed using the fiber optic cable, the result is a lightweight device that does not significantly restrict the user's mobility. The wireless transmission of the camera data to the computer contributes to this. The user can therefore move around the room and send commands to the corresponding devices integrated into the environmental control system quickly and easily with the blink of an eye.
Die Erfindung läßt sich in Bezug auf die angeschlossenen Geräte behebig erweitern, auch das Integrieren einer roboterähnlichen Mechanik, die mit ihren Bewegungen den durch die Blicke des Benutzers gegebenen Befehlen folgt, ist möglich. Über die Beobachtung von beiden Augen (beispielsweise durch zwei Kameras oder schnell klappende Spiegel) kann der Computer sogar auf einen im dreidimensionalen Raum fixierten Punkt schließen. Ebenso ist das System bereits zur Steuerung von elektrischen Rollstühlen vorbereitet: der Benutzer kann den Rollstuhl in die gewünschte Blickrichtung dirigieren.The invention can be easily expanded in terms of the connected devices, and it is also possible to integrate a robot-like mechanism whose movements follow the commands given by the user's gaze. By observing both eyes (for example through two cameras or quickly folding mirrors), the computer can even deduce a point fixed in three-dimensional space. The system is also already prepared to control electric wheelchairs: the user can direct the wheelchair in the desired direction of view.
Technik:Technology:
Das Ortungssystem, das die Position des Kopfes des Benutzers im Raum feststellt, kann in einem durch den Benutzer zu tragendes Stirnband untergebracht werden. Es enthält zwei Tongeber, von denen jeder in einer verschiedenen Frequenz Töne erzeugen kann - im Ultraschallbereich. Am Computer sind drei Empfänger - quasi Mikrophone - angebracht. Zu bestimmten Taktzeiten senden die Tongeber einen Tonimpuls, der von den drei Mikrophonen aufgefangen wird. Für die Strecke Tongeber - Empfänger lassen sich vom Computer nunThe positioning system, which determines the position of the user's head in space, can be housed in a headband that the user wears. It contains two sound generators, each of which can generate sounds at a different frequency - in the ultrasound range. Three receivers - microphones, so to speak - are attached to the computer. At certain times, the sound generators send a sound pulse, which is picked up by the three microphones. For the path between the sound generator and the receiver, the computer can now
Laufzeiten angeben - er registriert die Verspätungen, mit denen die Impulse nach Aussenden bei den Empfängern eintreffen. Daraus ermittelt er sechs Strecken (für jeden Tongeber drei) und weiß dann über die Raumkoordinaten von beiden Tongebern Bescheid, daraus auch auf die Drehung des Kopfes.Specify the travel times - it registers the delays with which the impulses arrive at the receivers after they have been sent out. From this it determines six distances (three for each sound generator) and then knows the spatial coordinates of both sound generators, and from this also the rotation of the head.
Die von der Kamera übermittelten Daten wertet der Computer aus und erhält die Koordinaten der Pupille des Auges.The computer evaluates the data transmitted by the camera and obtains the coordinates of the pupil of the eye.
Aus beiden Datenpaketen ermittelt der Computer die vom Benutzer fixierte Position und vergleicht mit gespeicherten Daten von angeschlossenen Geräten - stellt er fest, daß der Benutzer ein bestimmtes externes Gerät fixiert, so aktiviert oder modifiziert er es entsprechend.From both data packets, the computer determines the position fixed by the user and compares it with stored data from connected devices - if it determines that the user is fixating on a specific external device, it activates or modifies it accordingly.
