Blind man’s stick is a novel device designed to help blind or visually impaired users navigate safely and quickly among obstacles and other hazards. This review paper presents new thought a theoretical model and a system concept to provide a smart electronic aid for blind people. Mobility training uses a white cane for the blind or the visually impaired. Such cane, which enhances their own walking ability, is different from an approach that enables them to walk with mechanical equipment. When the stick’s sensors detect an obstacle, the embedded computer determines a suitable direction of motion that steers the stick and the user around it. The steering action results in a very noticeable force felt in the handle, which easily guides the user without any conscious effort on his/her part.
