Accessible Shopping Systems for Blind and Visually Impaired Individuals: Design Requirements and the State of the Art

ABSTRACT

Independent grocery shopping is one of the most functionally challenging tasks for visually impaired and blind individuals. Many assistive shopping systems have been developed to address the problem of blind grocery shopping. In this article, we identify several design requirements for assistive shopping systems and analyze existing approaches to see how well they meet them. Our objective is to shed some light on possible research and development directions for the accessible blind shopping community and to offer designers of accessible shopping solutions evaluation tools that can be used as initial points of comparison.
