Assistive Glasses Using Ultrasonic Sensors for Visually Impaired Individuals

To provide an efficient solution to the difficulty in navigation faced by the visually impaired, this paper presents a device built on the principle of object detection. This model utilizes ultrasonic sensors to detect an object that is present in front of the visually impaired individual. This device is built using Arduino Nano which serves as a processing unit, a battery as a power source, a buzzer for feedback audio cues, and an ultrasonic sensor that detects obstacles. The prototype is then implemented on a pair of glasses which makes it easy to use in everyday life. This is a portable, economical, and easy-to-use device that helps in safe indoor and outdoor navigation of the visually impaired thus, fulfilling the needs of visually impaired individuals.
