"Für die TU Graz interne Zeitschrift TUG Print haben wir eine Artikel über QR-Codes geschrieben. Das Ziel war in das Thema einzuführen und zu erklären wofür 2D Codes in Zukunft eingesetzt werden können."
In: Computers Helping People with Special Needs. Berlin/Heidelberg: Springer. (= Lecture Notes in Computer Science.) 1065-1069. In this paper a barcode-based system to help the visually impaired and blind people identify objects in the environment is introduced. The system is based on the idea of utilizing QR codes (two-dimensional barcode) affixed to an object and scanned using a camera phone equipped with QR reader software. The reader decodes the barcode to a URL and directs the phone’s browser to fetch an audio file from the Web that contains a verbal description of the object. Our proposed system is expected to be useful in real-time interaction with different environments and to further illustrate the potential of our work, two scenarios are presented.
