Definitions

  • the present invention relates to eyeglasses suitable for blind and/or deaf-blind people.
  • the invention relates to eyeglasses provided with sensors allowing to reveal obstacles and to indicate their distance to the user.
  • the amount of information involves vibrating interfaces rather bulky, or sound interfaces having different timbres and tones and mixtures of the same heavily occupying the hearing of the blind.
  • the sizes of the electronics is not negligible, being made heavier under the senso al point of view due to the needing of preserving the retina of people occasionally in front of the system with respect to damages. Further, the visible ray does not allow to the blind to unobserved, giving him an unpleasant psychological condition.
  • blind people mainly need: a) to know the configuration of the obstacles that could prevent its movement freedom within some meters; b) a system which does not create psychological problems during its use; c) not to create problems to people approaching the blind; d) an easy usable system.
  • a) to know the configuration of the obstacles that could prevent its movement freedom within some meters a system which does not create psychological problems during its use
  • c) not to create problems to people approaching the blind d) an easy usable system.
  • the finding has the aim of allowing to individuate eventual obstacles in front of the blind people, from the ground level to the view line of the same blind, within 6 - 7 meters, and to give the distance and the direction.
  • the solution suggested according to the present invention is light so as to be possible to house the same within an eyeglasses frame to allow to the blind, by little rotations of the head, to create a tridimensionai approximate image of the surrounding environment.
  • the finding is substantially comprised of a group of infrared emitters focalized on selected directions, for example coming out from a lens of the eyeglasses, and of an analogous group of suitable sensors, preferably provided on the other lens, or even in the same lens, revealing the echo of the return radiation from eventual obstacles.
  • the distance of the obstacle is electronically obtained by the triangulation of the emission line, of the echo line and of the emitter - sensor distance.
  • the information obtained by the various directions can be parallel transmitted to the blind person by tactile vibrators, or they can be transmitted sequentially (one direction after another direction according to a cyclic mode) by an auditory way.
  • the vibrating or audio frequency is connected with the distance of the obstacle.
  • control, detection and data transmission electronic is small and by an hybrid integration it can be housed within the side rods of the eyeglasses, if said rods are of the high kind.
  • the data communication system preferably of the tactile vibration kind (necessary for the deaf - blind people and not limiting for those not deaf), is housed within the ends of the same rods.
  • eyeglasses suitable for blind and/or deaf - blind people comprising at least one infrared ray emitter, connected to a first optical system, to lighten eventual obstacles according to pre-established directions, at least one reflected infrared ray receiver, connected to a second optical system, an electronic providing a signal function of the distance from the obstacle, and a tactile and/or sound vibrating interface providing to the blind people an indication about the distance of the obstacles.
  • said at least one infrared ray emitter is of the LED of laser diode kind emitting within the close infrared field, so as not to be dangerous for eventual observer which are close to the device.
  • between one and three emitters and between one and three receivers are provided, still more preferably two emitters and two receivers.
  • said emitters and said receivers can be provided on different lenses or on the same lens.
  • it can be provided a sole first optical emission system for all the emitters, or it can be provided one optical system for each emitter.
  • it can be provided a sole second optical receiving system for all the receiver, or it can be provided one optical system for each receiver.
  • said detectors can be of the PSD kind or CCD kind bars, sensitive to the infrared emitted by the emitters.
  • said electronic controls the emitters, detects the echo signals, generates signals proportional to the distances of the obstacles, associates to the same signals corresponding vibrations transmitted to the tactile interface, or corresponding frequencies codified for each sensor, sequentially applied to an earphone.
  • said electronic can be integral and housed within said eyeglasses, or within one lens, or discrete and remote and connected to the eyeglasses by a wire directly or by a connector device.
  • the eyglasses lenses can be realised in such a way to let the infrared passing and to strongly reduce the visible light, so that from the outer the components (emitters, sensors, mirrors, ecc.) housed inside cannot be observed.
  • figure 1 shows one person wearing eyeglasses according to the invention
  • figure 2 is a top view of the head of the person wearing the eyeglasses according to the invention
  • figure 3 is a front view of the head of a person wearing the eyeglasses according to the invention
  • figure 4 is a perspective view of eyeglasses according to the invention.
  • figure 1 it is represented the solution of the eyeglasses having three directions, which is deemed to be a good compromise between the information for the blind people and the encumber of the electronic in case the aim is to realise a solution completely housed within the eyeglasses frame.
  • One sensor 4 corresponds to each emitter 1, while the two optical systems 2 and 3 are common to the various emitters and sensors.
  • the position of the emitter 1 / detector 4 with respect to the corresponding optical system defines the direction.
  • the emitters 1 are infrared LEDs, the spectrum of emission which is connected to the spectral response of the detectors 4. Their directivity is enough pronounced so as to allow to exploit at best the focal opening of the next optical system: in the prototype LED having a peak wavelength of 890 nm, radiant flux of 15 mW and directivity of 50% at + or - 40° have been used.
  • An infrared radiation pulse is generated by the emitter 1 and sent toward the obstacle by the optical system 2.
  • the optical system has been realised by a mirror and an optic having a .5 focal.
  • PSD detectors have been used, said detectors having an output determined by the position of the image on their sensitive area.
  • the spectral response has the peak at 920 nm, but is wide almost twice the emission spectrum of the used LED, so that the fitting between source and detector is very good.
  • An integrated circuit e.g. the one manufactured by HAMAMATSU, H2476, executes the different needed functions: it memorises the value of the output from PSD immediately before the emission of the LED pulse, subtracts the memorised value from the value measured during the pulse in such a way not to be influenced by the background, and finally amplifies the signal. Further, it creates, among other things, an analogic signal proportional to the position of the image on the sensitive area of the PSD, directly performing the measure of the triangulation among emitter, obstacle and sensor. The minimum cycle between two following measures is 1.5 ms.
  • the analogic signal controls the frequency of a not stable multivibrator directly controlling the vibrator 7.
  • the analogic signal controls a VCO followed by a BUFFER operating the earphone.
  • Lenses 5 are treated: upon them an optic "coating" is laid, so that they are transparent only for infrared rays. From outside it is not possible to see the devices housed within the eyeglasses. The same kind of effect can be obtained employing a suitable plastic material for lenses.
