A New intelligent Shoe for Blind People Using Ultra Sound Waves for Obstacle Detection Base on Human Gait Cycle (A Replacement for White Cane)

In this research a new design of shoes was proposed to help blind people recognize the obstacles while walking. This can be a proper replacement for white cane. Furthermore، white cane has some deficits and we tried to remove them while designing this shoe، such as problem in recognizing depth and height. The mechanism informs while the person about the obstacle in the way through vibration on the person''s ankle. In the new structure the area around persons will be scanned (3D)، and constantly، there are some information about the area. And if the person reaches to an obstacle، a decrease in height، or an obstacle on the way of his body or his head، there will be warning via some vibrator motors. The main idea of producing such a device was from the mechanisms that use ultrasound waves to measure the distance، and they are widely used in radars and such devices. Making and using such waves are not harmful for health at all، I addition this shoe can make the electricity which needs with a small power generator so it does not need any external battery charge.
