Taking a whole boatload of feedback into consideration, the Ouya team has made several notable improvements to its controller. Developers that have had their hands on the consoles for a few weeks have started to give their recommendations back as to how the controller could be improved, and the team is taking it all to heart.
First, the D-pad on the controller has switched from a "disc" to more traditional "cross" layout, which should help prevent accidental movements. The thumbstick caps have been redesigned to give more grip, and the touchpad area has better sensitivity now. The triggers have been improved as well, and are now more flush with the body of the controller. And last but not least, the battery compartment has been redesigned for a tighter fit, and some materials will be changed out for higher quality ones by the time the final units ship.
Those are some notable improvements, changing basically all of the input surfaces on the controller. Ouya seems committed to delivering a high quality product to consumers, so let's hope this all comes through in the end.
