Microsoft has just unveiled a new accessory, the XBOX Adaptive Controller, which will be compatible for the XBOX One as well as Windows PC games. This new hardware is designed to work with many common adaptive switches a person with disabilities may own currently. The controller is fully programmable and has been designed to work for as many people as possible, while also staying affordable.
Look for Microsoft to share more details of the controller at this year's E3event in June.
