I work with people who have many kinds of disabilities, and I recommend all kinds of assistive technology on almost a daily basis that is designed to overcome challenges people may have to living independently. That being said, I think that it's fantastic to see that Xbox is getting an adaptive controller. The official description is as follows (from Microsoft):
"Designed primarily to meet the needs of gamers with limited mobility, the Xbox Adaptive Controller is a unified hub for devices that help make gaming more accessible. Connect external devices such as switches, buttons, mounts, and joysticks to create a custom controller experience that is uniquely yours. Button, thumbstick, and trigger inputs are controlled with assistive devices (sold separately) connected through 3.5 mm jacks and USB ports."

Description-wise, as you can see the Adaptive Controller features a large white base unit, with a few buttons and large pads and an amazing backside where all kinds of things can be connected. My thought on this is that if you combine this with the button mapping capabilities found in Steam to make any game/program on the pc work with a controller, then it is definitely going to open the door up for so many people to play/experience things they've never been able to do.
Microsoft, you done good.
