The Advanced Environmental Controls (AEC) unit is a VA innovation that enables injured Veterans to perform many important tasks independently. The AEC uses a variety of advanced technologies, including voice activation, touch screen, sip-and-puff straws, head-tracking, eye-pupil tracking and augmented communication to enable Veterans with limited mobility to control a tablet device held in place near them by a wall arm. Learn more about how the Cleveland VA Medical Centers and other VA locations with Spinal Cord Injury Centers have incorporated the technology for Veterans.
