Orientation and obstacle warning device ( 10 ), comprising a housing arrangement ( 12 , 14 ), a location device ( 34 ) with a transmitter ( 34 ') for directional electromagnetic or acoustic radiation and a receiver ( 34 ") for at an obstacle reflected electromagnetic or acoustic radiation, an electronic compass and egg NEN electroacoustic transducer ( 66 ), characterized by a pedometer ( 76 ), wherein a number of steps covered can be output in natural language at least via the electroacoustic transducer ( 66 ), and / or a light sensor ( 36 ) which designally generates a brightness indicator which has a variable value dependent on the determined brightness and which can at least be output as acoustic information via the electroacoustic transducer ( 66 ). 2. Einrichtung nach Anspruch 1, deren Lichtsensor (36) mit einer Vielzahl unterschiedlicher Helligkeits­ schwellen ausgestattet ist, wobei jeder Helligkeits­ schwelle eine spezifische akustische Information zu­ geordnet ist.2. Device according to claim 1, the light sensor ( 36 ) is equipped with a variety of different brightness thresholds, each brightness threshold is assigned a specific acoustic information. 3. Einrichtung nach Anspruch 2, bei der ein Helligkeits­ wert wählbar ist, bei dessen Erreichen eine Meldung erfolgen soll.3. Device according to claim 2, wherein a brightness value is selectable, when it is reached a message should be done. 4. Einrichtung nach einem der vorhergehenden Ansprüche, bei der aus dem Richtungssignal des Kompass und/oder dem Helligkeitsmeldesignal des Lichtsensors (36) und der Schrittzahlinformation des Schrittzählers (76) eine richtungsbezogene Weginformation gebildet wird, welche als natürlichsprachliche Information über den elektroakustischen Wandler (66) ausgebbar ist.4. Device according to one of the preceding claims, in which a direction-related path information is formed from the direction signal of the compass and / or the brightness signal of the light sensor ( 36 ) and the step number information of the step counter ( 76 ), which information as natural language information about the electroacoustic transducer ( 66 ) can be output. 5. Einrichtung nach einem der vorhergehenden Ansprüche, wobei Hindernismeldungen der Orientierungs- und Hin­ derniswarn-Einrichtung (10) Priorität vor den Infor­ mationen des Kompasses, des Schrittzählers (76) und des Lichtsensors (36) haben.5. Device according to one of the preceding claims, wherein obstacle messages of the orientation and Hinnisniswarn-device ( 10 ) have priority over the information of the compass, the pedometer ( 76 ) and the light sensor ( 36 ). 6. Einrichtung nach einem der vorhergehenden Ansprüche, deren Mikrocontroller (60) einen Datenspeicher (78) enthält, in dem Informationen aus der Ultraschallor­ tungsvorrichtung (34) und/oder dem Kompass und dem Schrittzähler (76) speicherbar sind.6. Device according to one of the preceding claims, the microcontroller ( 60 ) of which contains a data memory ( 78 ) in which information from the ultrasound processing device ( 34 ) and / or the compass and the pedometer ( 76 ) can be stored. 7. Einrichtung nach Anspruch 6 mit einer Betriebsart, in der die Daten der zuletzt gegangenen Wegstrecke rück­ wärts aus dem Datenspeicher (76) ausgelesen und unter Berücksichtigung der Richtungsumkehr (aus links wird rechts, aus Nord wird Süd) als natürlichsprachige Weginformation über den Lautsprecher (66) ausgegeben werden.7. Device according to claim 6 with an operating mode in which the data of the last path traveled backwards from the data memory ( 76 ) is read out and taking into account the reversal of direction (from left to right, from north to south) as natural language path information via the loudspeaker ( 66 ) are issued.
