We've now moved on to the next keynote, by Nina Wakeford from INCITE at the University of Surrey; I saw her keynote at ISEA2004, of course, but I think this one is on a different topic. I also just ran in to fibreculture's own David Teh - good to see another familiar face!
Nina considers how we might think about ubiquity - through developments of ubicomp, and through analogous social and cultural activities; also, how might we intervene in already existing ubiquity work? A guiding example is the 'gaydar', a new technology for gay men to find one another through mobile devices. What exactly is it that ubiquitous computing promises, what technologies may it replace?
