Hence, applications running on Windows Vista and a hardware platform supporting touch input like the HP dx9000 can and should take advantage of the touch technology. This section highlights the gestures supported by Windows Vista and provide links for more touch input manipulation. System Gestures A touch gesture is a quick movement of a finger on the screen that a computer understands. The following table lists the system gestures defined by Windows and supported by the hardware platform referenced in this paper. Windows Vista maps the following touch gestures directly into equivalent mouse events. If your application responds to any of the mouse events below, it will automatically respond to the corresponding system gesture on the supported hardware platform.
