An Enhanced Shopping Cart Guidance System for Visually Impaired Users with Passive Control Interface

Abstract

To address the challenges faced by visually impaired individuals in supermarkets, this paper introduces a shopping cart-type robot equipped with a camera and environmental markers for intuitive navigation. It employs a passive control strategy for safety and provides verbal and haptic feedback to guide users to their destinations. In ten validation experiments, the system effectively led blindfolded users to desired locations, demonstrating its potential as an assistive tool for visually impaired shoppers.
