The demo of Sigma R&D's gestural interface installed at the TTNet HQ. This video demonstrates the half circular gestures used to increase/decrease volume and change the channel. Bigger circles have different effects (mute, max volume, change channel by +/- 10)

Setup: A TV, running IPTV service, connected to a set top box, connected to a netbook, connected to a Kinect. Sigma NIL, Sigma R&D's natural interface library, is running on the netbook to enable gestural control of the TV.
