Phones can be used with minimal dexterity and voice commands. The small numbers of special users is, once again, exactly why items like this get marketed to the rest of us.

I disagree. To me it's like the (apocryphal) story of the US spending millions on developing a pen that can write in zero gravity and the Russians using a pencil.

There are plenty of simple solutions for shoes for the disabled - sandals, slip-ons, shoes with velcro straps etc; Nike created shoes that can self-tie from phone apps just because they thought it would be cool.

I mean, tbf slip-ons are nice but sometimes you do want lace-ups, and phones are pretty usable if you have low manual dexterity with the right modifications. More generally, a lot of Weird Products are more or less this-products aimed at physically disabled persons

Progress!

N.I.H. Head Calls for End to All-Male Panels of Scientists
Francis Collins pledged to decline to speak at conferences that do not include enough women in prominent speaking roles.


The New York Times wrote:In an interview after his statement was released, Dr. Collins said, “Certainly white men are wonderful contributors to the biomedical enterprise — I’m one of them. But at the same time, there’s a tendency to neglect the fact that we have lots of other people contributing to research.”

[...]

Dr. Collins said that from now on, whenever he is asked to speak, he will say that “we want to see exactly how you handled this issue of inclusiveness — please tell us what you’re doing.” He will ask to see the final roster 30 days before the event.

Dr. Collins said he was not going to require any quota for women as speakers or direct other N.I.H. scientists to follow his example because “I would not want anybody to do this because they’re forced to.”

He acknowledged that in some areas it might be challenging to bring in a significant number of women. “I want to be totally reasonable about that,” he said. “But I want to see the effort.”

That is impressive.
It is a delightful example of an ally.

We need examples.
That's how we learn.

The Pentagon has a laser that can identify people from a distance—by their heartbeat

The Jetson prototype can pick up on a unique cardiac signature from 200 meters away, even through clothes.


Which is a lot more useful than if it only worked at Black's Beach.

The first question is, how unique and consistent are individual people’s heartbeat patterns? Is it like retina or fingerprints where a person’s pattern remains stable over their lifespan? Second, do the patterns vary in a predictable way for a given individual when the person is under various stresses that alter heart rate?

Given that a person's heart rate will change as they improve their cardiovascular health from jogging or swimming, I'm going to assume that no, your heartbeat is not consistent over time the way the retina or fingerprints are.

Your heart rate also alters slightly just from breathing - it speeds up slightly when you breathe in, and slows when you breathe out (and is more accentuated the deeper the breaths). Generally easiest to see in children, but some adults keep it as well.

However, given apparently these cardiac signatures have been around for a while from the article, I guess there must be something unique in the patterns? Apparently some were just going off the pulse (I'd been wondering if there was some sort of valve thing you could detect from the chest) - even things like pulse pressure are changed by peripheral vasculature). If you take medications, does that change your signature? Is it not as good in the elderly if they have degenerative valvular disease? So many questions.

It probably has a fairly high rate of false positives/negatives.

If the rate of false positives is too high, then it would/should not be admissible as court evidence the way that fingerprints or DNA are. If the accuracy rate is below eighty percent or so (one false positive for every five or six true positives), then it should not even be used as justification for an arrest.

The article seems to imply its more than just heart rate since they say the signature cant be altered like facial recognition. What exactly is unique about a cardiac signature is presumably in the details of the tech.

One of the most jarring things after my daughter's heart transplant was being in her hospital room, just like old times, and seeing a wildly different (i.e., normal) EKG on her monitor screen. It was obvious that that was a completely different heart beating.

I can only imagine.
You two have had a highly unusual experience.
Because you did, you know more than we do

That must have been interesting from an emotional perspective, given how we still culturally think of the heart as the seat of the soul despite knowing that it’s in the brain...
