Intelligent Walking Stick for Elderly and Blind People

Abstract : Mobility for blind and elderly people is a problem as they have to face many difficulties in their day to day life. Most commonly, stick is use by blind and elderly people as a support for their body to stand and walk. The most common disadvantage of walking stick is user should have to be in close proximity of obstacle so that he can sense the location of obstacle to avoid bumping while waggling. We proposed a new concept of walking stick which is helpful for both blinds and elderly people to move in unfamiliar environment and monitor their medical condition. In this methodology we have used different sensors mounted on a walking stick which will help a user to navigate easily indoor and outdoor along with monitoring their health. Unlike other electronic blind stick which were helpful in detecting obstacle and alert user we designed a stick having multiple feature embedded in a single stick. This stick used for detecting obstacle, pit ,water on ground to some level, location of user, pulse rate detection, body temperature measurement of user and alert another person by sending message about the health issue of user or some other emergency.

 EXISTING SYSTEM :

 ? The system have the capacity to detect obstacles that exist on the ground during walks indoor and outdoor navigation. ? Moreover, many people simply afraid of being helpless in constant movement of people, vehicle and other road users.It is therefore advisable to offer new solutions of the problems with existing technologies. ? The idea of the proposed system came into existence because of a short visit to a blind school.

 DISADVANTAGE :

 ? This problem is very much prominent in old age people especially when they walk. ? In existing system they use IR Sensor to detect obstacles ,this sensor value doesn’t provide how long obstacle is there ,so blind people may get insufficient.

 PROPOSED SYSTEM :

 • This paper proposes an Node MCU based obstacle finding stick for visually impaired people, which helps a blind person by detecting the obstacles using Ultrasonic sensors and IOT application. • One button is used for the emergency text transmission purpose from the user and second one is used to know self-location of the visually challenged person. • When visually challenged person very near to object the vibration starts and speaker tells how near to obstacle and also send notification call to guardian . • The proposed method is a simple walking stick equipped with sensors to give information about the environment.

 ADVANTAGE :

 ? The performance and functionality are improved by the addition of alert Vibration, and voice guidance signal which is relayed to a miniature Speaker. ? The cost effectiveness of the proposed solution leads to compromises in performance. ? Their proposed stick was intended to provide low cost and efficient navigation aid for the blind. ? The use of IOT Data stored in server for instance, will be more advantageous in order to get up to date of person.
