BlindShopping: Enabling accessible shopping for visually impaired people through mobile technologies

Abstract. BlindShopping is a mobile low-cost easily-deployable system de-vised to allow visually impaired people to do shopping autonomously within a supermarket. Its main contributions are: a) a user navigation component combining an RFID reader on the tip of a white cane and mobile technology, and b) a product recognition component that uses embossed QR codes placed on product shelves and an Android phone camera for their identification. Furthermore, it provides a web-based management component to easily config-ure the system, generating and binding barcode tags for product shelves and RFID tag markers attached to the supermarket floor
