Tish Shute: This year we have seen gestural interfaces go mainstream. What are the most interesting directions for gestural interfaces that you have seen emerge in recent months?
Bruce Sterling: To me, the most “interesting” part is seeing people do gestural stuff in public. William Gibson, my fellow author, observes that cellphones have stolen the gestural language of cigarettes. There’s lots of fidgeting, box tapping, ash-swiping, slipping boxes in and out of pockets… People quickly learn to do that without thinking twice, and they forget how weird it looks. It’s “design dissolving in behavior,” as Adam Greenfield puts it.
