Shopping Assistance System for Blind Customers

Shopping Assistance System for Blind CustomersProject ID: SLIIT/CTP/2014/12

Bring the visually impaired customers to Super Market shopping culture..Our Vision..

IntroductionWhy Vision impaired customer assistance system? Estimated statistics reveal that 285 million people are visually impaired and out of this number, 39 million people are totally blind

Shopping behavior analysis Function Name Function Description F1Shopping list preparation F2Getting to super marketF3Finding products in storeF4Getting to cash registersF5PayingF6Getting to exitF7Getting home Our solutionIntegration of Three systems -Navigation System This function involves identifying the correct good shelves that the customer need, by comparing the shelfs ID number with customer inputs. The ID is given to each shelf using RFIDs. The RFID is captured by a RFID reader and that information is possessed by a mobile application, for further comparison. Depending on the position of a customer the system will deliver the relevant shelf name as a voice recording to customer.

Item selecting Soon after the customer receives the message that he is passing the correct shelf, he should stop and start selecting. For reading purpose the customer is given hand held RFID reader. Thus as mentioned in earlier function, each good is uniquely identified by a RFID chip and a recording will be played, uttering goods name each time customer reader the ID from reader.

Collision detecting System During the navigation period the customer is who control the navigation path of cart depending on the audible instructions. Thus there should be a way to identify barriers in front of the cart. We intended that again best way to solve this, is to let the customer to know about the barrier in front of him using a small alarm.Background -We found out several attempts on this issue.RoboCart

RoboCart was our first accessible blind shopping project that started in early 2004 [1] at the Computer Science Assistive Technology Laboratory of Utah State University (USU CSATL). The objective was to design a robotic supermarket shopping assistant for blind shoppers. A long-term collaborative agreement was negotiated with Lee's Market Place to grant us access to its supermarket in Logan, Utah for experimental purposes.

GroZi GroZi is an accessible shopping project at UC San Diego: 1) an accessible web site for blind and VI users to create grocery shopping lists in the comfort of their homes; 2) computer vision software for recognizing products and signs in stores; and 3) portable devices that can execute computer vision algorithms and give the user haptic and verbal feedbackIBM patentIn 2002, IBM acquired a patent on a method to provide VI shoppers with location and item identification at sites that have barcode labels. The patent describes a portable unit that assists VI shoppers at stores by providing them, through speech synthesis, with information on their locations from various barcode labels.
