Peripheral makers Nyko have announced a partnership with NVIDIA and have unveiled a line of game controllers for use with Android tablets. The controllers, the Playpad and the Playpad Pro, are optimized for use with Tegra devices and should work flawlessly with the Tegra 3 chipset. Devices are also required to be running Android 3.0 and above with Bluetooth capabilities.

The controllers will be useable right from the outset, no rooting, hacking or tweaking is required. Through a free application too known as Playground, support for legacy apps that aren't optimized for Tegra devices will be possible as well providing they meet the necessary criteria.

The Playpad will be the smaller of the two devices, and will come with dual analog sliders, a carry case and a collapsible tablet stand. The Playpad Pro by contrast is a full sized gaming controller, with dual analog sticks, a D-pad, shoulder buttons and face buttons.
