eBay uses iPhone head tracking to help you shop hands-free
Online shopping can be difficult if you don't have full use of your hands, since it frequently assumes that you can tap or click your way through a sale. eBay could make internet purchasing more accessible to just about anyone who can use a phone, though. It developed an open source project, HeadGaze, that uses head tracking on the iPhone X (and, we presume, future iPhones) to enable hands-free shopping. It uses Apple's ARKit framework to create a "virtual stylus" that follows your head movements. When you combine it with an interface designed for shopping, you just have to look at the right part of the screen to scroll, add items to your cart and check out.
