We've now experienced JVC's Snap and Gesture HDTV
-- the display that replaces your remote by responding to audio cues like snapping/clapping, or visual ones with hand gestures -- and can confirm we are exactly the type of lazy couch potatoes this is not aimed towards. While leading a nation, signaling for a time out or expressing displeasure with another driver are best done with elaborate hand movements, we're a bit more thumb-oriented. Check out some lazily-snapped photos (auto focused, not manual) in the gallery.
