Xbox SmartGlass is essentially an app for smartphones and tablets that allows Xbox 360 developers to create content that could be streamed to the app. This would allow smartphones and tablets to double up as a secondary display of sorts, much like how the Nintendo 3DS’ dual displays, where one displays the main gameplay while the other displays information like maps, status, etc.
In time for Electronic Entertainment Expo (E3) at the Los Angeles Convention Center, Microsoft have unveiled their future console in the Xbox line. The Xbox SmartGlass is essentially an app for mobile devices that can stream content. It’ll also allow those mobile devices to double up as a secondary display of sorts, particularly useful during gaming. Added social functionality is a bonus for the SmartGlass’ experience. It’s said that video functionality is compatible with iOS and Android devices, and extended game functionality appears was specifically noted for Windows devices only (i.e. Windows 8 tablets and Windows Phone devices).
