Microsoft officially announced a new controller system designed for those with limited mobility. Called the Xbox Adaptive Controller, it's more accurate to call this a base system in which add-ons can help gamers with specific mobility assistance.
The Xbox Adaptive Controller is a white slab-like controller, the same one that was leaked earlier this week. However, that was only the tip of the iceberg. The large pad is customizable with two large pads with programmable controls, a D-pad, a Xbox home button, and two select buttons. But the ports on the base system also allows for extra joysticks, buttons, and other controls to be added-on for even more flexibility.
Microsoft says that the Adaptive Controller will be out "later this year," and will cost $99.99. Microsoft released a full blog post on the history and design process for the controller which is very much worth a read.
I think this is a phenomenal idea, and amazing concept that will hopefully open up gaming to a far larger audience, and maybe potentially lead to some really cool possibilities for all gamers. The customization, accessibility, and flexibility of the Adaptive Controller is something the gaming community needs.
