INTENTION :

             According to WHO 39 million peoples are estimated as blind worldwide. They are suffering a lot of hardship in their daily life. This innovation is to develop a cheap and more efficient object detector to help visually impaired to navigate with greater comfort, speed ,confidence and to encourage them to strive further valiantly. From my project we can attain upshot like

• The person can move anywhere confidently without the help of others.
• It is affordable for everyone.

NOVELTY OF THE PROJECT :

It is designed to overcome the lack of visual sense, by using other senses like sound and touch. It uses audio and vibration signals to notify the user about upcoming hurdle.

ELUCIDATION OF BUILDING BLOCKS :

Arduino Uno, a microcontroller is used as it is a open source electronic prototyping platform. In this innovation ultrasonic sensor HC-SR04( distance sensor) is used  as it is economical sensor which provides 2cm-400cm of non-contact measurement functionality, here the ultrasonic sensor act as an object detector. Buzzer and vibration motor is used to notify the user about the upcoming hurdle. In this innovation buzzer is used as it can withhold voltages from 4v-8v D.C.As it is very small, it gets fixed perfectly into the glove and since it's resonant frequency 2300khz , it will travel around very small distance and it won't disturb the people near by . In this project ,vibration motor is used as it is a core less D.C motor and it is compact ,the main purpose of the motor is to alert the user whenever the object gets detected.

WORKING PRINCIPLE :

                      Whenever the sensor detects the object , the buzzer and vibrating motor will receive the signal that the object is detected, then the buzzer will alert the user through a beep sound and sense of vibration through vibration motor.
