As usual, mobile phone companies come up with great patents that we never see implemented, so this time Sony Ericsson comes up with a software to use the camera to the maximum...to recognize patters and human movements, quite crazy but I've seen it being implemented for disabled people. This is how the world will end up lazy...or maybe it will encourage us to work and improve the technology, I don't know...

As you can see, you should be able to customize gestures and actions. Example:
If you lift your finger, the Email would be synchronized, if you turn your fingers, the volume would go up, etc.

At Unwired View they even proposed awesome events as if answering a phone on loudspeaker from a distance, controlling TV and other appliances, shooting a group photos, etc.

We must also look at the other factors, I mean you wouldn't want to dry up the battery in half an hour would you? Those darn fuel cells are taking way too long...
