Nowadays, safer and more accurate systems have been achieved through the development of ‘intelligent’ sidewalks and ‘talking’ walking sticks.
In Fukuoka City, on their ‘intelligent’ sidewalks for the visually impaired, they use a special walking stick, equipped with a magnetic sensor. The user touches the sidewalk where the magnetic labels (ferrite) have been laid and signals are then delivered enabling him/her to walk safely along the sidewalk. It also provides messages such as, “This is Tenjin 1-chome, turn left and you will head for Fukuoka City Hall” from a loudspeaker embedded under the sidewalk at a point where an antenna is buried.
In Sendai City, the visually impaired use small transmitters and sensors. They are informed vocally of their location and direction by the use of a sensor attached to their walking sticks, and a card-sized buzzer or receiver system with a small transmitter.
In Yamaguchi Prefecture, the visually impaired are detected automatically, and their directions determined through reflective tapes and infrared sensors attached to their walking sticks. At each diverging point the visually impaired are automatically informed vocally and along Braille blocks as to their location and direction.

There are many spiritually blind people groping around in utter darkness!
In whom the god of this world (Satan) hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them. 2 Cor. 4:4
Satan is the god of darkness -- there is no light in him and he cannot give light to any man! He is a master of keeping his followers in a world of utter gloom and the blackest of nights!
In Luke 6:39 Jesus said, "...Can the blind lead the blind? shall they not both fall into the ditch? "
If you desire to walk in brilliant light, Christ gives marvelous sight and insight! After Jesus made a blind man to see "He answered and said, Whether he be a sinner or no, I know not: one thing I know, that, whereas I was blind, now I see. " John 9:25
Even the blind can "see" when they are in Christ. Even those blind in sin can "see" and walk in marvelous light when Christ indwells them! Don't you want to truly see? Just ask God to take away your sin! And He will take the blindness that Satan puts in our hearts away!
