After Kinect had faded from the spotlight, PrimeSense’s technology found a new home for itself, after being bought by Apple at the end of 2013. PrimeSense’s sensors were shrunk down and used to build FaceID. From the iPhone 10 onwards, each device essentially packed a tiny Kinect into the notch above their displays. Facial recognition isn’t limited to iOS devices, and is available on plenty of other smartphones, tablets and even PCs thanks to Windows Hello.
This is Microsoft’s modus operandi: poorly implement an amazing technology with bad taste. Repeat.
