The Sony Ericsson Yari may miss the mark as the most innovative slider, but only if you don't look closer. Upon a second look, you will find that the Sony Ericsson Yari is a tiny little thing that's full of surprises.
The Yari has got a pretty decent 5 megapixel auto focus camera, but it's main focus point is another thing - gesture gaming. And we're not talking about accelerometer-based gesture recognition.
Thanks to an optical tracker technology developed by GestureTek, the Sony Ericsson Yari can use its camera to detect your movements and translate them into games moves. It can even do wireless multiplayer.
