The Android controllers
There are a variety of controllers and accompanying apps that essentially turn your tablet or smarthphone into a console that connects to your TV. These controllers blur the definition of “microconsole,” and are a viable option for developers who want to add a “10-foot experience” to their games.
A couple of the most prominent Android controllers are the Green Throttle and PowerA’s MOGA line (MOGA also supports Windows Phone 8).
The premise behind controllers like these is that people already own their “microconsoles” -- their mobile device -- and really only need an HDTV adapter, decent console-style controller and couch-friendly UI to complete the experience.
Green Throttle and MOGA’s SDKs are available on their websites, which explain how to get started.

To state again: This is meant to be a living document -- something that you can use as a continually updated reference. We’ve collected a good amount of information here, but if you have anything else you’d like to add to our Android microconsole reference guide that would be helpful for game developers, just mention it in the comments below or email me, Gamasutra EIC Kris Graft, at email@example.com.
