Jason wrote earlier this week about the potential for QR Codes to help librarians annotate the real world though digital metadata.
If you enjoyed this post, you should check out Ellyssa Kroski's July 2008 issue of Library Technology Reports, "On the Move with the Mobile Web: Libraries and Mobile Technology".Ellyssa was way ahead of the curve, exploring this topic in a Report that is still very relevant in 2010. An excerpt:
[New] search technologies enable mobile users to find information related to the world around them by employing pattern recognition technologies or utilizing quick-response (QR) 2D barcodes. Mobot enables cell phone owners to take photos of posters, magazine pages, CDs, billboards, and brand logos in order to connect with mobile content, Web sites, information, and purchasing options. Thrrum allows camera phones to take point-and-click snapshots of any text found in books, on billboards, in stores, and so on in order to receive related search results. The Semapedia project strives to tag real-world objects with 2D barcodes that can be read by camera phones (see figure 17). When phones scan these barcodes, users are led to encyclopedic entries from Wikipedia. You can create your own Wikipedia barcodes on the site, as well as locate a link to install your own barcode reader. 2D barcodes can also be easily created on Winksite or Semacode Web sites.
We've made the digital version of this issue publicly available for a limited time through our new online archive, hosted by MetaPress. You can view each chapter either as PDFs or HTML, and the text is fully indexed and searchable.
As Mobile services become a larger part of the library world, we'll hope you'll find this material helpful to your library's planning.
