5 of the best new concept phones

BlackBerry Empathy by Kiki Tang and Daniel Yoon
Remember mood rings? Well, this touchscreen phone works a bit like that, except it's not naff. A biometrics ring works alongside the hexagonal phone to collect your "emotional data". Your emotional status is then transmitted to a social network-style system, which by the time this phone makes it into production will be some kind of super platform that obliterates Facebook, Twitter and Google Plus. User avatars are surrounded by two rings that show your previous and current emotional state, with an Emotional Health Chart on hand to put it all into a handy timeline. An optional feature allows friends to view your chart – but would you really want them to know you were bored senseless while they prattled on about their new girlfriend? Probably not. An OLED screen that becomes transparent when not in use and opaque when it senses interaction sounds pretty nifty, though.
