Freaky. I like it. It occurs to me that probably the next (somewhat more difficult) step from there is making the entire head move, and eventually you work up to entire body movements.
There was also that tech demo I can't find any more of using a webcam/desktop computer rig to real-time take video of a celebrity, and have it make the facial expressions of an actor.

Edit: found it.

And here I thought Facerig stuff was impressive. (Well, it is neat that it does CGI and drawn characters, but not quite so impressive.)

Huh; I just noticed that for a lot of the models, the whole head does move (albeit only a little). Missed that the first time. I suppose that the more the head has to turn, the harder the modeling is.

That's gonna be ungodly expensive ($475,000 per infusion, apparently), and a qa/manufacturing nightmare. Interesting stuff though!

I think Gilead paid $12B for Kite.

The company is quick to point out it's less expensive than bone marrow transplants, and they won't charge if there's no sign of remission in the first month. Still, cool stuff, though. And, yeah, expensive. How's that single payer thing going?

No idea about your last sentence, db.

So Apple's big new iPhone development is Face ID. The iPhone X will have no home button and unlocks by looking at your face.
That's cool and all, and I'm sure facial recognition will bring about loads of great new capabilities. But are people really going to like this. I mean, if you have to take your sunglasses off and open your eyes and whatever, every time you want to use your phone. I wouldn't be surprised if certain kinds of makeup threw it off as well.

I think some models of Android already have been capable of that, but would unlock for a photograph of a person's face.

I don't quite see how you secure this against a photograph. I get that a low-quality photograph should not be enough to unlock the phone, so the random thief who gets the phone that accidentally fell out of your pocket on the bus is not going to easily break this.

But a sophisticated thief hanging out in a touristy area could easily take lots of pictures through a good camera without attracting suspicion. At some point in the day they get someone's phone, put it in front of a good screen displaying the photos at the right distance, and I'm not sure how they don't break in.

So, for the unsophisticated thief this seems as difficult as anything else. For the sophisticated thief this seems easier.

Forget thieves. Private investigators could have a field day with this. Even if the phone is really sophisticated about getting the image from a particular angle or whatever, a PI can surely get several pictures at different angles and use some software to reconstruct a picture from whatever angle and distance the phone wants.

Presumably it also has a code, and you can set it to only open with the code the way you can with the current fingerprint ones. You can even do it on an ad-hoc basis without unlocking the phone.

Not to mention cops can access such phones at will and easily erase incriminating audio, photos and videos stored locally.

I might be wrong, but I thought I heard a reporter say something like "It uses 24 infrared data points". So if it's using infrared, a photo won't work. The number of things that will keep it from working really seems to be the FAIL of this idea to my mind.

If IR is used, maybe a hard copy photo won't work, but I wouldn't be surprised if a photo on another phone screen would do the trick.

The cops won't need any photo tricks. They'll just detain you, confiscate your phone, and hold it up to your face.

That would be my concern. You won't be able to withhold your passcode from the police if they have you in custody.

Same problem exists with fingerprint unlock.

Exactly. Or with bandage/eye patch.
In the demo I saw, the phone wouldn't unlock until the guy opened his eyes.

But I think it's probably the case that the phone will be unlockable via code just as the current iphone can be unlocked with fingerprint or code. In which case, face recognition is just that much more convenient.
