Eyes-Free Barcode Localization and Decoding for Visually Impaired Mobile Phone Users

An eyes-free barcode localization and decoding method is presented that enables visually impaired (VI) mobile phone users to decode MSI (Modified Plessy) barcodes on shelves and UPC barcodes on individual boxes, cans, and bottles. Simple and efficient barcode localization and decoding techniques are augmented with an interactive haptic feedback loop that allows the VI user to align the phone's camera with a fixed surface in the pitch and yaw planes. The method is implemented on a Google Nexus One smart phone
