This web-based remote control for computers, tablets and TVs is designed to help those with physical disabilities, by letting users control devices with their eyes. Using their own eye-gaze software or other assistive technology, users log in to Xfinity’s free site and can surf, search and record just by looking at different buttons on the web page. For many, it will be the first time they’ve had the power to change the channel. —Josiah Bates
