Third Eye for Blind

Abstract

People with visual impairments often depend on outside help that can be provided by the following agencies Humans, well-trained dogs, or special electronic devices are used as decision support systems. Principal The problem for blind people is how to navigate where they want to go. Those people need Help from other people with good eyesight. As described by the World Health Organization, 10% of people with visual impairment have There is no functional vision to help them move safely without assistance. This article is Designed to help blind people overcome visual defects through the use of other senses, such as sound and Touch. The system uses the Atmega328 microcontroller, which is a high performance 8-bit AVR RISC microcontroller. To detect the distance, the system uses HCSR04, an ultrasonic range Finder distance sensor module. The sensor module is designed to use sensors to measure distance The SONAR or RADAR principle uses ultrasound to determine the distance of an object. This The system also includes a buzzer that generates an alarm sound and a motor that generates vibration. Sign. The system uses audio and vibration signals to notify users of upcoming obstacles. What The distance between the glove and the obstacle, the frequency of the audio signals and vibration is reduced Increase. Therefore, the system helps to simplify the navigation process for those who need it. The system provides a Low-cost, reliable, portable, energy-efficient and powerful navigation solutions Response time is short.
