Abstract - One of the biggest problems faced by the visually impaired is navigating from place to place. The adverse conditions of the roads make it even more difficult for them to walk outdoors. They have to be alert at all times to avoid consequences like colliding with stable or moving obstacles, ascending or descending staircases, slipping down wet terrain. Also, at times they may be in distress and might want to send an alert message to their relatives or friends about their whereabouts. These problems of blind people can be addressed with the intervention of technology. The proposed solution employs the Internet of Things (IoT) paradigm to provide a medium between the blind and the environment. Several sensors can be used to detect anomalies like obstacles, staircases and wet terrains respectively. The prototype discussed here is a simple, sophisticated and affordable smart blind stick equipped with various IoT sensors and modules. Also, this solution provides a way to send a message about the whereabouts of the user to the concerned people. A software application is designed to help the acquaintances of the blind to manage the stick’s configuration ex: add or delete phone numbers to which alert messages have to be sent. Misplacing the stick indoors can also be a substantial issue.
supported with a rechargeable port. Hence they are rechargeable.
1.1 Location Identification The blind person will be notified when they are close to public places. Transceivers are used to communicate between the blind stick and traffic signal. The signal will initiate a vibration notifying the place of location. each traffic signals are supported with different frequencies so that we can differentiate the signals from different transceivers. The same setup can be installed in mall, hospital, school etc
1.2 Indication to the Public An additional red light is displayed when the blind person press a button in order to cross the road. The red light is associated with the regular red stop symbol. This additional light is provided to give a public attention. People in the traffic will be notified with the extra light symbol.
2. SYSTEM DESIGN System consists of transceiver, led, push button, ultrasonic sensor, regulator IC, BMS module, vibrating module and a rechargeable port. Wireless Communication is the algorithm that we use in this design. To meet this wireless technique transceivers are used to establish the connection. Arduino is the microcontroller used here. Arduuino Mini is implemented in the stick in order to occupy within the small radius.

1. INTRODUCTION According to the World Health Organization, there are nearly 285 million people with some form of visual impairment out of which 86% people have low vision and 14% people are blind. Vision is one of the most important sense to humans to survive. Vision helps to connect with the surroundings. People deprived of vision rely on other dependencies like a simple walking cane or other people. In familiar places like the interiors of a house, they memorize the site directions, obstacles on their way and navigate according to them. However, it is not always safe for the blind to rely on their memory to move from one place to another. Especially when they are out-doors. Not all the times blind people are offered help from others and hence there is a need for a device, such as a stick, which can assist the visually impaired people in all forms of life. Transceivers and all the associated components are connected to Ardino Micro controller. Disabled person will be assisted with a vibration in the blind stick when they come in contact with a traffic signal. The button associated with the cane when pressed will displays an additional red light along with the red stop symbol. The blind stick is also provided with battery and is

2.1 EXISTING SYSTEM Existing systems like canes can guide blind people by helping them detect the obstacles in their path through touching/poking. Alternative to the above method some other aids include smart belts, smart rings, smart canes etc., which can assist them by detecting obstacles using ultrasonic or laser sensors. These systems produce either an audio or vibration in response w.r.t the detected obstacles to warn them. The limitations of existing systems are as follows: Expensive , Not very effective and reliable ,Have very limited features and usability.
