Visually impaired people find difficulties detecting obstacles in front of them, during walking in the street, which makes it dangerous. The smart stick comes as a proposed solution to enable them to identify the world around. In this paper we propose a solution, represented in a smart stick with ultrasonic sensor to detect any other obstacles in front, left and right of the user, within a range of four meters. Moreover, another sensor is placed at the bottom of the stick for the sake of

... g puddles. The vibration of motor is activated when any obstacle is detected. The blind stick is integrated with ultrasonic sensor along with GPS &GSM based Navigation/Tracking system. This proposed system uses the microcontroller ATmega 328 embedded system. The stick is capable of detecting all obstacles in the range 4 meter during 39 ms and gives a suitable respect message empowering blind to move twice his normal speed because she/he feels safe. The smart stick is of low cost, fast response, low power consumption, light weight.
