While we don't have many details about how it works exactly, you can see in the image how it has grooved impressions at the top which represent all of the Xbox controller's different functions, which would help users who favor touch over sight to program different buttons, and two large "A" and "B" buttons which are presumably programmable. It also features a 3 light LED similar to the previously leaked Xbox Elite V2 controller, which could be to indicate when different programmed modes are active. It also looks as though it has a USB port and 3.5mm audio jack on the left side.
Expect more details in the near future, but this is just another example in a huge list of commitments Microsoft and the Xbox team has been making to help those with unique accessibility needs.
From a 2018 leak to a supported accessibility product
The “likely” launch predictions above are historical reporting from before the announcement. They should not be read as a current product rumour. Microsoft now provides an official Xbox Adaptive Controller product page; use it for the currently described features and compatibility rather than treating an old leaked image as the specification.
For an accessibility setup, begin with the actions a player needs to perform and the inputs they can use comfortably. Then check which external switches or accessories are required and how the complete setup will be mounted. Compatibility is a requirement for the whole arrangement, not just the central controller. This update does not claim a hands-on assessment or that one configuration suits every player.
