Infra-red sensor, 1080p full HD camera, surround sound, wide infra-red sensory bandwidth, operates in the dark and in the bright, has wider range, has voice recognition software, allows menu navigation via hand gestures and voice commands, will not respond to unregistered voices, will automatically sign you in, will automatically switch the settings to your preset settings and anybody else who is registered whenever you hand the controller over to that person, measures heartbeat, muscle texture mapping and breathing rate, blood pressure etc. It's ultra sensitive unlike the current one which Angry Joe has assured people, does not really work. Ever. Plus a bunch of other stuff too. Like, Skype, Snap, power on, power off etc.
