In the Android 4.0 Ice Cream Sandwich SDK, some developers find a game control function which let users connect game controller with a USB port. This means your next Android smartphone or tablet can control Xbox 360 games or PC games.
From the Froyo ( Android 2.2), Android added some basic human input device, like keyboard and mouse, support. But the new game control attracted developers attention. Some developers once used Bluetooth to build connection between Android and Wii. But the former solution need some specific apps support and can just used to control Gameboid. Now the Ice Cream Sandwich can control Wii, PS3 or Xbox 360 directly. www.itgeeg.com
Use the game controller, we can free from the touch screen control ( This does not mean touch screen control is not good. We just think some of games will be more exciting if we can control with a hand shank.). And the new feature can brings more idea for developers. They can use this function to control other apps.
As the hardware developed, like Tegra 3 or more powerful processors, Android devices can run high revolution games perfectly. It can even connect to TV with HDMI port.
