The video shows the new NextWindow Gesture Server Application.
Info from the NextWindow website:
"NextWindow Gesture Server Application in conjunction with a NextWindow touch screen enables two-touch gestures to be used on the Microsoft Windows Vista desktop and certain applications.
You perform a gesture by double-tapping or dragging two fingers on the touch surface. The Gesture Server interprets these actions as commands to the operating system. For example a two-touch vertical drag on the Vista desktop can adjust the computer's audio volume control up or down as required."
Also from the website:
Vertical scroll: drag two fingers up or down the touch screen.
Horizontal scroll: drag two fingers left or right on the touch screen.
Zoom: move two fingers apart or together.
Double Tap: double-tap two fingers on screen.
"You can enable or disable the two-touch functionality and adjust the sensitivity of each of the four two-touch gestures. You can also select the command that is executed with the double-tap gesture."
