Microsoft’s Adaptive Accessories are designed to be customizable inputs

Microsoft has announced a lineup of adaptive accessories which are meant to augment or replace the regular keyboards and mice that people with disabilities could struggle to use. The lineup consists of three different devices: the Adaptive Mouse, Adaptive Buttons, and the Adaptive Hub. The mouse and buttons are made to support 3D-printed accessories so you can customize them to work the way you want them to.
