BLaDE (Barcode Localization and Decoding Engine) smartphone app in action

BLaDE (Barcode Localization and Decoding Engine) is an Android smartphone app designed to enable a blind or visually impaired user find and read product barcodes. The primary innovation of BLaDE, relative to most commercially available smartphone apps for reading barcodes, is that it provides real-time audio feedback to help visually impaired users find a barcode, which is a prerequisite to being able to read it.
