Opera 10 with Face Gestures
You may have seen this already, but I come across it now. New Opera 10 has a “Face Gestures” feature that allows you to make face gestures at your PC to control common browser commands. You can go to “Home”, go next, back, speed dial and do other stuff with this feature. Obviously you need a PC with a built in camera or an external web-cam for this feature to work. Following is a subset of the supported face gestures.
You can start by viewing this demo video below and can download the browser from this link.
