News of Sony Ericsson’s Yari mobile phone was leaked earlier this year.  On the surface, it doesn’t seem like there’s a lot new here – quad-band GSM, 5 MP camera, video camera, non-3.5 mm headphone jack.  But the real news with Yari is its gesture gaming technology.

The device uses a camera to track the movement of users, and uses this movement to control games.  Gesture gaming has been used in Japan for years, but this is the first time such technology has made its way to the States.

With the push for gaming on mobile devices, it’ll be interesting to see how popular the Yari is.  Like other gaming platforms, though, this one seems to rely heavily on software – a lack of games on this device could make the Yari a flop, while conversely a killer app could elevate the Yari to Wii status.
