Gaming User Interface
In the past decade or so, most gamers would agree that gaming experience had improved vastly. Not only in terms of graphics or game play, the gaming interface has seen big changes as well. I'm sure many had seen or at least tried playing one of these before:

Nintendo Game Boy

Nintendo Game Boy Color

Nintendo Game Boy Advance

Notice how much the game boy series changes over time. From a non-colour device to a coloured device, to a differently shaped device. The change in shape is to cater for a better grip for users, the addition of colours is straightforward.

Sony Playstation

Sony Playstation 2

Sony Playstation 3

As you notice, the controller design remains the same, indicating a sign of consistency. However, the difference is in that the latest instalment of the PlayStation series has a wireless controller for the convenience of users. Speaking of convenience, the Xbox kinect doesn't even require a controller.

It works by hand gestures and voice recognition. This makes iterating on the interface much easier for users. Slick? Absolutely. Judging from the changes seen, one would not be surprised if the next generation of gaming interface would involve some brain computer interface.
