There's plenty new in iPadOS 15, but it also features an under-sung accessibility upgrade: support for third-party eye-tracking devices. That'll allow people with disabilities to use iPad apps and speech generation software simply through eye movements -- no touchscreen interaction required. Tobii Dynavox, the assistive tech division of the eye-tracking company Tobii, worked with Apple for years to help make that happen. And now, the firm is ready to announce TD Pilot, a device that aims to bring the iPad experience to the estimated 50 million people globally who need communication assistance. The TD Pilot is basically a super-powered frame for Apple's tablets: It can fit in something as big as the iPad Pro 12.9-inch, and it also packs in large speakers, an extended battery and a wheelchair mount.
