Smart Assistive Stick with Enhanced Mobility and Independence for the Visually Impaired Using Ultrasonic, GPS, and GSM Technologies

This paper presents the design of an advanced assistive stick for visually impaired individuals, integrating ultrasonic sensors, GPS tracking, and GSM communication to enhance mobility. Traditional walking sticks have limitations in detecting obstacles, which can hinder independent navigation. The proposed solution improves upon conventional designs with ultrasonic sensors for faster and more accurate obstacle detection, reducing accident risks. GPS tracking provides real-time location data, aiding navigation in unfamiliar areas, while GSM technology enables emergency alerts and location sharing with caregivers. Additionally, the device includes a feature to help users locate the stick if misplaced. By enhancing safety, independence, and inclusivity, this smart navigation tool supports equitable opportunities and improved well-being. It contributes to sustainable development goals and aims to enhance the autonomy and quality of life for individuals with visual impairments.
