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.
At the University of Huddersfield we have used QR codes to deliver context appropriate help and information to blur the boundaries between the physical and electronic world. We’ve developed mobile friendly materials to deliver information skills materials directly to our users at the point of need, linked by QR codes on printed materials and on appropriate locations in the physical library. This article outlines the practical uses we’ve found for QR codes and gives preliminary results of how they’ve been received by our library users.
application that uses inexpensive off-the-shelf office supplies and a standard inkjet or laser printer to enable users of the iPhone to make audio labels or text labels that are read aloud by their phone.
CrossRef has created a sample API that will take a CrossRef DOI and turn it into a QR Code. The QR Code will include the title of the document pointed to by the CrossRef DOI as well as the “htttp://dx.doi.org” URL of that will allow you to link to that item. Most mobile phone QR Code readers will allow you to bookmark, share or link to the URLs thus encoded.

open source (LGPL) library for generating QR Code, 2-dimensional barcode. Based on libqrencode C library, provides API for creating QR Code barcode images (PNG, JPEG thanks to GD2). Implemented purely in PHP, with no external dependencies (except GD2 if needed)
We strongly believe bringing knowledge to places and things that matter to others is a great way to help others understand our beautiful and complex world. To accomplish this, we invite you to create and distribute Semapedia-Tags which are in fact cellphone-readable physical hyperlinks to the free online encyclopedia Wikipedia (or any of Wikipedias' sisterprojects such as Wikibooks, Wikinews , and Wikinews ). You can create such Tags easily yourself by choosing and pasting a Wikipedia URL into our creation-form . Pressing the button will generate a custom PDF file to download and be printed.
ZXing (pronounced "zebra crossing") is an open-source, multi-format 1D/2D barcode image processing library implemented in Java. Our focus is on using the built-in camera on mobile phones to photograph and decode barcodes on the device, without communicating with a server.
Mobile Geräte werden aufgrund erhöhter Bandbreite und Usability weltweit immer populärer. Auf ihnen fließen die Funktionen eines Computers, Audio-Players, Fotoapparats und Mobiletelefons zusammen. In Zusammenhang mit diesen neuen Technologien, nimmt die mobile Nutzung des Internets drastisch zu und stellt auch an Bibliotheken die Herausforderung, ihre Dienstleistungen in virtuelle Umgebungen einzubetten und Inhalte und Dienste mobilen Nutzern anzubieten. Mobile Technologie kann für verschiedene Bibliotheksdienste genutzt werden: mobile Interfaces, Lokalisierungsdienste, Multi-Media-Führungen und SMS-Benachrichtigungen. Während in Deutschland mobile Dienste in Bibliotheken eine noch unbedeutende Rolle spielen, nutzen US-amerikanische Bibliotheken bereits ein breites Spektrum. Diese Arbeit soll nach einer Einführung in die Thematik anhand ausgewählter Praxis-Beispiele veranschaulichen, welche der mobilen Dienste bereits von Bibliotheken in den USA und Deutschland angeboten werden.
