I’m doing a presentation on the 1st of May about my work for the Signals in the City exhibition and its forced me to think about qr-codes on a deeper level than most people seem to engage with. I've come to the conclusion that  looking at qr-codes just by themselves or just in terms of their technical aspects is a rather superfical approach.

The thing about qr-codes that really interests me is that they are physical world hyperlinks: how does this affect people? what impact does this have on social activities mediated by computers/ handheld devices?  It is this linking between physical and virtual spaces that I find intriguing, not the advertising, or the idea that I could call a taxi just by taking a photo of it (with its qr-code emblazoned on its side), not the idea of buying a bottle of coke just by taking a photo of the vending machine that it is in. Although these are amazing ideas this is where most people stop because these ideas in themselves are money making and sometimes I think that this can limit people’s ability to push an idea to its limits.

We need to think about how a user interacts with a mobile phone, their expectations when they take a photograph, what it means to be “in the world” physically while interacting in virtual space. People multitask when they use mobile phones, their attention spans are short and usually data rates are an issue. How do these affect all affect the experience of the user?

Going back to the physical word hyperlinking, if we stop for a moment and question the semiotics of such an act there is so much in this it could be a book in itself. In the 3^rd year of my undergrad degree I did performance studies, and the most informative aspect of the whole year was a research project I did on the Semiotics of the Theatre Experience. I never thought such a project would be useful now, but it is – semiotics of space, breaking down of actor vs audience space could be related to breaking down of virtual vs physical space where the audience belongs to the physical world and the actors to the virtual….
