This system assists the blind to navigateI.INTRODUCTIONon their own . in case of emergency situations such ashigh traffic density the location of the member is sharedto the family members The prototype model consists ofa stick and a hand cuff within built pulse detector. Thestick with sensors deployed can detect the obstacles inThe survey conducted byWorld HealthOrganization in 2017 estimates that there are327 billion people in world with visualfront with sensors and it will produce various buzzerimpairment, 36 billion of people are blind andsounds depending upon the direction. The buzzer would258 billion are with low vision, and around 24alert the user. Furthermore, the Sensors on stick canmillion people are blind in India,. This systemdetect the water and fire on ground and informed to thedesigns and develops a portable unit (stick) forperson by buzzer. The hand cuff is equipped with inthe blind people for easybuilt GPS , GSM and pulse detector equipments , soplaces. The stick with long cane structure withthat if the member pulse falls below a threshold levelthen his location will be shared to his family. By trialand error method the system can detect obstacles suchas pedestrians, objects , water and heat with greaternavigation in allsome alteration at hand cuff parameter is usedbecause it can feel the path nature and detectobstacles in the path of the blind person. Beingan emerging area of research, a review of theaccuracy761
