Microsoft's screen multi-touch technology Surface

A long time ago, I saw a video showing the multi-touch technology of the touch screen on Youtube. Today, Microsoft also introduced the same technology, which no longer uses one finger, but multiple fingers to operate the touch screen together, and uses gestures to naturally make some actions, such as zooming, zooming, placing, rotating, etc. Can also work with several people to complete a task, hope Microsoft early implementation of such a technology, is simply cool ~~~~~~~~~
