Blinds always meet a problem when they take buses because they
do not know when to get off clearly
because of their weaknesses. The device we designed will display the name of the next stop in braille,the blind can touch it and know whether they should get off.the device is attached to the handrail in bus.it has stored all the information previously,and it will adjust to display the next stop automaticlly by the signal it get from the bus.
