Microsoft Research uploaded an old video to its YouTube channel a few days ago showcasing a "versatile controller concept for mobile gaming." The video was made back in 2018, but represents work carried out between 2012 and 2014, so it goes back a bit!
It's still a really interesting showcase, however, highlighting how the controller could potentially operate with mobile and tablet devices, which ultimately could prove invaluable for Project xCloud users. It starts off by demoing the controller as a standalone device, before revealing how it can be snapped in half and clipped to the side of a tablet.
The potential downside, as Windows Central has noted, is the lack of bezels most phones and tablets have these days compared to a few years ago, making it difficult to clip anything onto the side of a screen without taking up too much space. That said, this controller is simply a concept, and there's every chance the final design (if it ever comes to fruition) will look nothing like this.
What do you think of the concept? Would you buy one to use with Project xCloud? Let us know in the comments.
