Acoustic Version Of QR Codes (+VIDEO)
The unusual concept design of acoustic barcodes has been developed by researchers from The Carnegie Mellon University. The bars are etched into a physical material such as wood, glass, stone, plastic and can be in form of a sticker, or 3D printed. Once you scratch a fingernail, a pen, a phone or any hard-edged object across the barcode a unique sound will be produced; a software app will then process these waveforms to create and identify the binary ID. The most interesting thing about this innovative concept is that these barcodes could serve like acoustic version of QR codes, NFC, and RFID. This gizmo might be widely used in retail shops to make passive display objects more interactive, e.g scratching the acoustic barcode to hear more information about the product.
