I did a bunch of mini interviews at the Microsoft BUILD 2011 Windows 8 conference.
The following video shows a Microsoft employee giving a quick description of the new Microsoft Touch Mouse.
The Touch Mouse is a new mouse from Microsoft that uses natural gestures including some of the most common tasks that people do with Windows, like opening and moving between windows and task switching.
In addition, Touch Mouse uses gestures that engage the whole hand. Touch Mouse also features BlueTrack technology, which lets people track on virtually any surface.
