The idea of gesture-based remote control isn't new, but GestureTek has added in 3D tracking to the mix for, you guessed it -- even more expressive interaction with your TV. After all, you don't live in flatland, so why should your remote control gestures? Of course, adding in depth perception requires the use of more than one webcam, but maybe that's not a big tradeoff in our age of six and more speakers in the living room. The setup will be on display at CES (sans Xpletive), so we'll try and swing by for a, um, hands on while we puzzle over how to add voice commands to this system. Watching the big game with your buddies just might get even more entertaining yet.
