The release this week of the Windows 8.1 Update added a number of new features to the OS, mostly for keyboard and mouse users. This week, the Microsoft Research team posted information about a project describing a possible future update for Windows 8 that involves interactive live tiles for its Start screen.
Finally, the third video shows how interactive live tiles could be used by a person at work with Windows 8. At one point, the person uses his Windows Phone and brings it to the monitor running the Windows 8 Start screen to bring up a message notification in the live tile inside the smartphone. It"s currently unknown why Microsoft Research posted this information to the public site and then removed it.
