Ultrasonic obstacle detector for blind

We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. The blind stick is integrated with ultrasonic sensor along with light and water sensing. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves.

This Arduino smart cane can assist with walking alone in new environments by taking inputs through an obstacle sensor ( ultrasonic sensor) and providing feedback to the . A Wearable Ultrasonic Obstacle Sensor for Aiding.

The system consists of ultrasonic sensors, microcontroller, vibrator, buzzer, and water detector in order to guide visually-impaired people. It uses servo motors, ultrasonic sensors, and fuzzy controller to detect the obstacles in front of the user and . Since early eighties, active devices for obstacle detection have been proposed. Such system are commonly known as Electronic Travel Aids (ETAs) and have been mainly based on use of laser and ultrasonic ( US). Arduino Tutorial - Ultrasonic Sensor HC-SRwith Buzzer and LED ( Distance Meter ) - Duration: 4:07. Sensor can detect obstacles within the designed range (1cm) to avoid the blind person through the issuance of.

He is accomplishing this by mounting an array of ultrasonic sensors around some tennis shoes. It uses speech feedback to aware the subject about the detected obstacle and its distance. This proposed system uses AT89Smicrocontroller based embedded system to process real time data collected using ultrasonic sensor network. Based on direction and distance of detected obstacle , relevant pre-recorded speech . Obstacle detection module, supported with heat detection and haptic modules.

The person wearing it is indicated abut the obstacle by vibrations prod. Reducing blind spots and improving driver visibility are important issues for operators of road-going vehicles.

Over the past few years, safety devices such as additional mirrors or camera systems that give wider viewing angles have become commonplace and even mandatory under blind spot .

In this context, developing an assistive technology that can interpret in real-time the urban scenes and provide to the blind and visually impaired users with fine . In Italy, the number of VI subjects is estimated in 5300 of whom about 50are blind. ABSTRACT: A smart stick has been built for the visually impaired people that help to detect obstacles with the use of infrare ultrasonic and water sensors. Obstacles within the distance of about 3m can be detected with the help of these sensors. Also, we make use of GPS module to give positioning and navigation to the .
