Smart Shopping Trolley for the Visually Impaired
Empowering Independent Shopping Through Technology
The Smart Shopping Trolley is an innovative assistive solution designed to help visually impaired individuals shop independently and confidently. By combining Artificial Intelligence, computer vision, and voice assistance, the trolley provides real-time guidance throughout the shopping experience.
The system can identify products, detect obstacles, guide users through store aisles, and provide audio instructions for navigation. It also supports automatic billing and product information retrieval, creating a seamless and accessible shopping environment.
Project Overview
The Smart Shopping Trolley for the Visually Impaired is an inclusive, assistive hardware and software ecosystem designed to provide complete shopping autonomy to individuals with visual impairments. By integrating precise indoor navigation, real-time product recognition, and an intuitive audio-assisted dashboard, this system eliminates the need for sighted assistance in retail environments, allowing users to navigate aisles and manage their cart confidently.

🎯 Key Features
Audio-Guided Indoor Navigation: Utilizes an integrated supermarket mapping matrix to compute optimized pathways, directing users safely from the store entrance to specific item aisles.
Proximity & Distance Metrics: Features a real-time aisle proximity tracker that continuously calculates and reads out the exact distance to selected grocery items.
Smart Cart Management: An automated list interface updates cart contents dynamically as items are added, ensuring the user always knows exactly what they have selected and how much distance remains to the next item.
📈 Project Impact & Deliverables
1. Restoration of Shopping Autonomy
Dignity and Independence: Empowers visually impaired individuals to complete grocery shopping entirely on their own, removing the awkwardness or reliance on store employees or companion assistance.
Seamless Field Execution: By replacing visual elements with clear audio feedback and distance alerts, the system creates a predictable and relaxed retail experience for the user.
2. Intelligent Path Planning & Safety
Accurate Aisle Navigation: Prevents collision and disorientation within busy retail layouts by guiding users along mapped paths with real-time aisle proximity alerts.
Time Efficiency: Reduces wandering time by dynamically tracking the user's position relative to their shopping list, converting a chaotic environment into a structured grid.
