Applications For Object Hyperlinking
The object hyperlinking systems described above will make it possible to link comprehensive and editable information to any object or location. How this capability can best be used remains to be seen. What has emerged so far is a mixture of social and commercial applications.
- The publishers of the Lonely Planet guidebooks are issuing yellow arrows with one of their guidebooks and encouraging travellers to leave tags to stories and comments wherever they go.
- Siemens see their virtual tagging system being used to tag tourist sites, and also leave messages for friends. They also suggest that virtual tags could be used to link advertisements with locations. Geominder also offer a virtual tagging service.
- Nokia have demonstrated that when a 3220 phone with the RFID shell attached is tapped against an RFID-enabled advertisement, a URL can be read and information about the advertised product or service returned to the phone.
- Japanese consumers are able to read barcodes with their mobiles and download comparative prices from Amazon.
- Semapedia have created a system for linking physical objects and Wikipedia articles using the Semacode tagging scheme. Graphical tags can be created that link to the URLs of individual Wikipedia articles. These tags can then be attached to the physical objects mentioned in the Wikipedia articles. Reading a tag with a camera phone will then retrieve an article from Wikipedia and display it on the phone screen. This creates the Mobile Wikipedia advocated by Mobile Weblog and Eclectica.
- An alternative to using 2d barcodes is to apply computer vision techniques to identify more complex patterns and images. Companies like kooaba, Daem, or Neven Vision (acquired by Google in 2006 ) develop image recognition platforms to turn any image into object hyperlinks.
- Microsoft has developed a system for creating hyperlinks using image matching.
- Google is now planning to tag 100,000 businesses in the United States with QR codes.

Famous quotes containing the word object:
“In the one instance, the dreamer ... loses sight of this object in a wilderness of deductions and suggestions ... until ... he finds the incitamentum, or first cause of his musings,... forgotten. In my case, the primary object was invariably frivolous, although assuming, through the medium of my distempered vision, a refracted and unreal importance.”
—Edgar Allan Poe (18091849)
