Abstract

The invention relates to an orientation aid for blind persons, in which orientation at unknown locations is facilitated for the blind person. This is achieved by means of a conventional ultrasonic transducer which transmits ultrasonic tones and waits for the echo. If there is a change in the time which the ultrasonic tone requires, the device warns the blind person of an obstacle.

Description

Die Erfindung betrifft eine Orientierungshilfe für Blinde. An Orientierungshilfen für Blinde sind meines Wissens bisher nur teuere, unhandliche Geräte bekannt, die nach Art einer Brille zu tragen sind. Für die meisten Blinden sind diese Geräte uner­ schwinglich und wenig praktikabel.The invention relates to an orientation aid for the blind. As far as I know, orientation aids for the blind are only available expensive, unwieldy devices known to be like glasses are wearing. For most blind people, these devices are not essential affordable and not very practical.

Aufgabe der vorliegenden Erfindung ist es somit, eine Orientie­ rungshilfe für Blinde anzugeben, die trotz einfacher und kompakter Bauweise ein Optimum an Zuverlässigkeit bietet. Zudem soll die besagte Orientierungshilfe preisgünstig herstellbar und ästhe­ tisch ansprechend gestaltet sein.The object of the present invention is therefore an orientation to provide assistance for the blind, despite the simpler and more compact Construction offers an optimum of reliability. In addition, the said orientation aid inexpensive to manufacture and aesthetic be designed appealingly.

Diese Aufgabe wird durch die im Kennzeichen der Ansprüche 1-7 angegebenen Merkmale gelöst.This object is achieved in the characterizing part of claims 1-7 specified features solved.

Nachstehend wird die Erfindung an Hand von zwei Ausführungsbei­ spielen erläutert. Es zeigtThe invention will now be described in two ways play explained. It shows

Fig. 1 die schematische Darstellung der in der Hand zu tragenden Version der Orientierungshilfe. Fig. 1 is a schematic representation of the version of the orientation aid to be carried in the hand.

Fig. 2 zeigt die schematische Darstellung der Version, bei der die Auswerteinheit getrennt vom Ultraschallwandler, verdeckt am Gürtel oder einem anderen Kleidungsstück getragen wird. Fig. 2 shows the schematic representation of the version in which the evaluation unit is worn separately from the ultrasound transducer, concealed on the belt or another item of clothing.

Wie in Fig. 1 dargestellt, sind sämtliche für den Gebrauch nö­ tigen Teile in einem Gehäuse (1) untergebracht. Der Ultraschall­ wandler sendet Ultraschallwellen aus und empfängt deren Echo. Die Auswerteelektronik (3) steuert das Senden der Wellen und mißt die Zeit die zwischen dem Senden des Signals und dem Empfang des Echos vergeht. Dadurch erkennt die Schaltung Objekte die sich innerhalb der Reichweite der Schallwellen befinden. Wird ein Objekt bemerkt, so wird es dem Blinden über den Schallgeber (4) oder den Tongenerator (5) mitgeteilt. Gespeist wird die Orientie­ rungshilfe durch einen eingebauten Akkumulator, der durch die Ladebuchse (7) von außen geladen werden kann.As shown in Fig. 1, all parts necessary for use are housed in a housing ( 1 ). The ultrasound transducer emits ultrasound waves and receives their echo. The evaluation electronics ( 3 ) control the transmission of the waves and measure the time that elapses between the transmission of the signal and the reception of the echo. As a result, the circuit detects objects that are within the range of the sound waves. If an object is noticed, it is communicated to the blind person via the sound generator ( 4 ) or the tone generator ( 5 ). The orientation aid is fed by a built-in accumulator that can be charged from the outside through the charging socket ( 7 ).

Fig. 2 zeigt die Ausführung, bei der der Blinde nur den Ultra­ schallwandler in der Hand tragen muß und die anderen Teile am Gürtel, an einem anderen Kleidungsstück oder in einer Tasche mit sich führen kann. Fig. 2 shows the version in which the blind person only has to carry the ultrasound transducer in his hand and can carry the other parts on his belt, on another piece of clothing or in a bag.

Die Erfindung funktioniert folgendermaßen:The invention works as follows:

Bei der Orientierungshilfe für Blinde gemäß Beispiel 1 und 2 werden Ultraschallwellen von einem Ultraschallwandler (2) ausgesandt und das Echo, das entsteht wenn die Wellen von einem Objekt zurückge­ worfen werden, wieder aufgefangen. Durch die Verzögerung läßt sich feststellen, ob ein Objekt im Weg ist oder nicht. Diese Information wird dem Blinden durch akustische Signale übermittelt. An Stelle der akustischen Signale ließe sich auch ein kleiner Vibrator auf der Haut befestigen. Das Gehäuse läßt sich außerdem noch ergono­ misch gestalten, wodurch man es besser halten kann.In the orientation aid for blind people according to Examples 1 and 2, ultrasonic waves are emitted by an ultrasonic transducer ( 2 ) and the echo that arises when the waves are thrown back by an object is collected again. The delay can determine whether an object is in the way or not. This information is transmitted to the blind person by means of acoustic signals. Instead of the acoustic signals, a small vibrator could also be attached to the skin. The housing can also be designed ergonomically, which makes it easier to hold.
