The earlier plot, technically known as the Hand-ID, is certainly the more bizarre of the two. When you hold your hand over the Z-camera to register your palm, the phone actually identifies you by the telltale pattern of the veins in your hand. Pretty macabre, no? It is a pity, however, that the Hand ID is actually very hard to use properly. The problem is, it's almost impossible to set up the right hand on the first attempt (1
These AirMotion gestures are luckily a little easier to live with. And this is how they work: To gain the attention of the phone, you have to make a kind of claw with your hand in front of the camera. (I'm absolutely serious.) From there, you can enable app shortcuts that you've set up before, play and pause your media, and even dismiss incoming calls with a swipe.

Even so, these gesture controls actually work and are surprisingly practical even during my limited takeaway time.
