ARDUINO BASED CUSTOMIZED SMART GLASSES FOR THE BLIND PEOPLE

Abstract

For all human beings’ vision is primary requirement to survive in fast-changing environment. Scientific glasses are there to improve the eye sight of visually impaired people. But for blind people there is a need for smart glass to guide them to be independent. For that introduced a method to support visually challenged people. The existing methods are available to identify obstacles, stair cases, water proximity separately as well as combined. This Project extended the existing smart aid techniques for obstacle detection with the fire detection and also the background detection with a low cost solution using the input and output sensors connected through Arduino board. The environment in front of the subject is detected by sensors and then the signal will be sent to the processor. The processor will respond to the input and sends the corresponding signal to the output transducer. The buzzer sound or beep sound from the output transducer will alert the user accordingly.
The proposed model of smart glass for visually impaired enhance the features of the existing obstacle detection models. It is an embedded system integrating the pair of ultrasound transducer, flammable gas or smoke detector and Light Dependent Resistor (LDR) to identify the objects like obstacles, fire, smoke and darkness. The information obtained from sensors is given to the Arduino processor. Arduino UNO process the information and sends corresponding signal to buzzer. The corresponding buzzer sound will help the subjects to identify the objects or obstacles accordingly.
