A Multitask Grocery Assist System for the Visually Impaired: Smart glasses, gloves, and shopping carts provide auditory and tactile feedback

According to the World Health Organization, "285 million people are estimated to be visually impaired worldwide" [1]. Several technologies such as automatic text readers, Braille note makers, and navigation assistance canes have been developed to assist the visually impaired. Concurrent advances in computer vision and hardware technologies provide opportunities for a visual-assistance system that can be used in multiple contexts. As part of the Visual Cortex on Silicon program, we have been developing interfaces, algorithms, and hardware platforms to assist the visually impaired with a focus on grocery shopping. This article describes the various features that we have incorporated into this visual-assistance system so that it can be used in multiple contexts.
