I was in a meeting with Tim Kindberg this week. He works for HP in research and development at the HP Labs in Bristol. One of his projects is physical hyperlinks. This is by no means a new technology - it's already been put to use by the BBC and won an award.
The idea is that physical objects could have a unique barcode printed on them that can be photographed by a mobile phone. The image leads to a unique reference point on the web which contains information. The technology was used as part of the BBC series Coast. Scenic walks were marked with posters that included these tags and linked to various pieces of information. You can learn more on the Active Print site.
There are a couple of barriers to this technology taking off. Having seen it in action, though, I'm much more convinced than I was. Properly integrated into phones it could be very easy to use and very useful. The phone tells you when you've succeeded in capturing the barcode - a major plus for usability.
There are, by the sounds of it, two major hurdles. The first is getting the appropriate software embedded into phones. The second is standardisation of codes.
This technology has all kinds of possible applications. The 'barcode' could, in theory, execute any number of activities on a phone. It could probably replace phone numbers on business cards, for instance.
It could definitely act as an easily traceable response mechanic on outdoor and ambient advertising. It could add real value to consumers and be easily trackable for media spend optimisation.
Some of the ideas that Tim covered were:
real time travel information at bus stops and on train platforms
in-store promotions
response mechanism on outdoor
incentive delivery on outdoor to increase footfall
map download from online to mobile
