Ultrasonic spectacles help the blind and visually disabled to better orient themselves. The direction, size, distance and space distribution of obstacles located in the field of vision up to 6 m distance are quasidigitally displayed by vibration generators mounted on the forehead or by optoelectronic signal generators. In order to accurately locate obstacles, the ultrasonic spectacles have an ultrasonic emitter in the centre of the spectacle frame and two ultrasonic receivers that work separately, have separate evaluating logics and are arranged at the left and right in the spectacle frame. The ultrasonic spectacle is designed in such a way that the sensors and vibration generators of the electronic ultrasonic system may be built into optical spectacles in order to assist vision.
