The FOCUS application for mobile devices is a camera function with a fun new wrinkle. In fact, it’s an experimental prototype that the Ars Electronica Futurelab (AT) came up with as a way to foster social interaction. Installation visitors can use it to take a picture of any motif they select and produce it in the small, round format of a button (the kind you pin to your lapel). Then it can be uploaded to the FOCUS-website and shared with others. The presentation at the FOCUS terminal in PostCity invites festivalgoers to select a photo from the collection and generate it as a button users can take home with them.
