Of course, there are quite a handful of tools available to help you out with controlling PCs via gestures, but nothing is as easy as Fultter, a Chrome extension designed to control PCs via gestures. Flutter is Kinect for your computer. It uses gestures detected via built-in camera in your computer to play, pause and skip songs & videos in YouTube, Pandora, Spotify, Grooveshark, iTunes, Netflix, and more. It also allows you to control slide shows in Apple’s Keynote using hand gestures!
It works even when YouTube tab is not in focus or Spotify, iTunes, and other apps are playing music/video in the background. Head on to the official Chrome Store Page to know more about it and try it out for yourself! Source – Flutter
