Comprehensive Assistive Mobility System for the Visually Impaired: The Smart Blind Stick with Ultrasonic Sensor Solution

An advanced blind assistance device integrates an ultrasonic sensor, Arduino UNO board, buzzer, and GSM module to create a cost-effective solution for enhancing the safety and autonomy of visually impaired individuals during navigation. The ultrasonic sensor detects obstacles, sending signals to the Arduino UNO, which activates the buzzer to alert the user. The GSM module enables emergency communication, transmitting distress messages to a predetermined contact. This Smart Blind Stick comprehensively addresses the needs of visually impaired individuals by offering features such as obstacle detection, navigation assistance, and a panic button. The ultrasonic sensor identifies barriers, triggering the buzzer for alerts and warnings of moving objects. The device facilitates road crossings during traffic signals, contributing to a safer navigation experience. In critical situations, the GSM module becomes crucial, allowing users to dispatch emergency messages to designated contacts for swift response and assistance. The overarching goal is to empower visually impaired individuals, fostering a sense of relief and self-dependency in their daily mobility. This innovative device amalgamates advanced technologies to provide a tailored solution to the specific challenges faced by the visually impaired community.
