Humanity grows as technology grows. Growth is complete only when it is uniform and common. In places where growth is uneven, technology steps in and happens to be the game changer. Ours is one such project that is aimed at bringing uniformity in the navigation of visually challenged people just like the common people. The project aims to aid the safe navigation of the visually impaired people. This helps the individual in reaching the destination, guiding them throughout the way and warning them about the obstacles that are awaiting their way through vibration and synthetic speech output by means of a headset. Thus preventing them from colliding with the obstacles. This adds on value to the conventional cane that has been used since ages. It makes use of an ultrasonic sensor to calculate the distance from the obstacle, a NodeMCU upon which the operational program and all the other components are based, a vibration motor to alert the person and an IR sensor to detect the obstacles through IR rays. Along with the function of guiding, it also has a backup protection plan in case of emergency. Wherein an alert message containing his location is sent to the person�s predetermined friend through GPS and GSM which is enabled through Wi-Fi module, thereby preventing any further complications. A pulse sensor is also used to have a basic monitoring of the person�s pulse rate. Thus, the project assures the visually impaired people to travel alone safely and confidently without the fear of getting lost or meeting with accidents anymore.
