So how long before our phones can measure heart rate from your pocket, or being held in your hand?
They already can by putting your finger on the camera and lighting up your finger with the led light. Then it detects the rhythmic changes picked up by the camera… At least 10+ years ago. It was a good novelty feature, but turns out, for most healthy people, checking your heart rate gets old after a few runs.

Hm I’m not sure I’d say it’s perfect? I thought 70-80 was?

This technology is being touted by the companies putting them in place to be a cost saving measure as staff no longer need to print new labels and manually replace them for products on the shelf. This is true in that it is a benefit of digital labelling, however there are many other usage options that could be implemented after installation.
alter prices around lunch hour for ready meals and snacks at retailers in walking distance to secondary schools
automatic increases for products being purchased more rapidly than historical averages to capitalize on a yet unknown trend
increases simply as stock begins running low
Imagine in a few years when this technology is combined with network snooping of phone identification, loyalty rewards card purchase histories, and automatic buying of customer information from data brokers, all to create a profile that predicts when a person would be likely to be menstruating and the moment they walk in the store, the hygienic products they buy every month raise in price by 30%.
Good point. A US department store chain – Kohl’s – has been using electronic shelf labels that change several times per day. Not sure how they handle the discrepancies.
How do I prove the product was prices $1 when I picked it up if the label now says $2? Is it my responsibility to notice the register price was different?
I more or less avoided Kohl’s, so I’m not sure how that was handled.
The only solution for that which I see is taking photos of the labels for every product taken off the shelf, but that’s quite the imposition obviously. Trouble is there are no laws guiding these practices, and the result is going to be quite the mess for customers to understand.
In my opinion, the best purchasing experience for this type of shopping is using a handheld device with which you both scan the product as you take it off the shelf, and also process payment on your way to the exit. No cashier lines, and even better, no more unloading and repacking of your items just to purchase them. From the shelf into your bag, only back out again in your kitchen.
On another note, it boggles my mind to see the square footage used by all these self checkout machines when these terminal systems exist. Sadly I’ve never used one in North America. This is an aspect of shopping that could make me loyal to a single vendor. I would actually install the vendor’s phone app if they built in this functionality instead of having these terminals.

Presence detection through WIFI was already garbage enough, this one is plain unusable.
You need more power than what regular people use. You would need the signal to go through walls into your home, and then read whatever comes back out through the same walls, so it’s a lot more attenuation than you typically expect.

I’m not super familiar with fiber. There’s no modem or anything needed? Don’t they still track data usage? Are they able to do that without any intermediate equipment?
Fiber that runs into your house can work with any fiber-ready router. So, yes, it’s a modem in a sense, but also does the router/wifi job as well.
However, if you have Verizon or Huawei device on the end of your fiber line, your ISP can likely connect to that device, specifically for things like seeing if anyone is home. They don’t need to do that, as it’s only data for them to collect to work out advertising profiles.
Once your data leaves your house and goes into their network, then it’s just your data on their network. Yes, they can see the data being routed, unless you use a VPN. So your options are going from your ISP able to see when you’re home, to not giving them access to anything and just paying the bill every month.

Yeah sadly it is paywalled, but I have been lucky enough to get access to it through my university.
Heres what I found regarding your question in the article:
Fig 1 illustrates Pulse-Fi’s system architecture which consists of three main components: data collection using commodity Wi-Fi devices, a CSI signal processing pipeline, and a custom lightweight Long Short Term Memory neural network for heart rate estimation.
And this is the Setup they used to collect the ESP-HR-CSI Dataset (left site) and the one that other researchers used to collect the E-Health Dataset (right side):
A. ESP-HR-CSI Dataset
We collected the ESP-HR-CSI dataset from seven participants (5 male, 2 female) in a room of a public indoor library. It was collected using two ESP32 devices, one as the transmitter and the other as the receiver. The sampling rate is 80 Hz, with a 20 MHz bandwidth with 64 subcarriers positioned at different distances. Each participant was measured at distances of 1,2 and 3 m for 5 minutes each. The participants sat in a chair between the devices and wore a pulse oximeter on their finger to collect ground-truth information as seen in
B. E-Health Dataset
The E-Health dataset [20] contains CSI collected from 118 participants (88 men, 30 women) in a controlled indoor environment measuring 3 m×4 m (Fig 4). The setup consists of a router set in the 5 GHz band at 80 MHz bandwidth as a transmitter, a laptop as receiver and a single-antenna Raspberry Pi 4B with NEXMON firmware for CSI data collection (234 subcarriers). Participants wore a Samsung Galaxy Watch 4 for the ground truth.
Each participant performed 17 standardized positions or activities, with each position held for 60 seconds.
To me it sounds like, that they really just used standard WIFI to collect the data (this is especially true for the E-Health Dataset), since all the processing gets done on the Raspberry Pi.

It may be possible, but I have no clue. It may also be, that the position of the router and the Laptop is important, but that’s probably something you would have to test.
All these Wifi for tracking people methods use the channel state information (CSI) that is used to help decode the transmitted data. CSI is obtained from pilot signals that are transmitted as part of a regular transmission. This is done in basically all digital communication standards, so you could do this not just with Wifi but also with 4G or 5G or older mobile communication standards. This is all not very surprising, there is a lot of research in contactless radio based heart rate monitoring, they usually build on radar systems not communication systems though. The buzzword for 6G for all this is joint communication and sensing.

The problem is not sharing and accessing, but generating. If we had a system where people would be paid for generating knowledge, then they wouldn’t have to charge for accessing knowledge.

It has nothing to do with that. This is about privacy and data security.
If we think about the applications of the technology to the benefit of someone’s health I think it’s really cool.
Needless to say it does pose a risk to our privacy and data security if used with an intention to monitor ones health without their consent.
Capitalism asks whether you are the kind of person harvesting people’s health info without concent or selling aluminum mesh underwear with fearmongering campaign. No other choices.
Insurance companies…sorry you’re denied for being a health risk…we can see from your home internet that you’re an unhealthy person
Remember kids, you can buy your own home fiber router! Don’t live with someone else’s equipment between you and the internet.
Care to explain what you mean? Are you saying you can run fiber in your house? Doesn’t that still require some form of equipment from an ISP to actually go out to the internet?
The fiber line into your house from the ISP is needed. What that fiber line connects to is up to you. The router your ISP provides isn’t special. You can get your own equipment.
I’m not super familiar with fiber. There’s no modem or anything needed? Don’t they still track data usage? Are they able to do that without any intermediate equipment?
Fiber that runs into your house can work with any fiber-ready router. So, yes, it’s a modem in a sense, but also does the router/wifi job as well.
However, if you have Verizon or Huawei device on the end of your fiber line, your ISP can likely connect to that device, specifically for things like seeing if anyone is home. They don’t need to do that, as it’s only data for them to collect to work out advertising profiles.
Once your data leaves your house and goes into their network, then it’s just your data on their network. Yes, they can see the data being routed, unless you use a VPN. So your options are going from your ISP able to see when you’re home, to not giving them access to anything and just paying the bill every month.
So the tricorder in Star Trek was just a fancy, battery powered wifi hotspot??
It was named after the sarcastic comment its early users would say to the people offended, “Try cords”.
Yeah but it ran on Linux.
If it could do that this whole time why did I invest a bunch of money and a whole lot more time in fancy mmWave presence sensors?? 🥲
Capitalism
Inb4 the cops starts doing nonconsensual “polygraph tests” using wifi
Those 5G Conspiracy Theorists probably feel vindicated after reading this lol
I rather think they will be let down, given we’re on wifi 7, not 5G, and also no injected nanites were involved.

The Paper: ieeexplore.ieee.org/abstract/document/…/metrics#m…
This is very cool and useful, but at the same time very concerning. While I see a lot of good use cases for this ranging from hospitals to stress recognition in animals I Am also quite scared, that big corporations will use this to spy on us. Luckily currently it is only possible to measure the pulse at about 3m, but it should be possible to increase the range. It may fall short when multiple persons are in detection range, but as far as I have read from the paper they did not test this.
Sure, everyone is getting spied on by everyone because everyone is so damned important to everyone.
Let’s try again: someone is getting spied on by someone because someone is so damned important to someone. And there’s a lot of someones.
Health data is extremely valuable. You can use it to serve more personalised ads or even use it to, as example, define prices for health insurance. When you combine it with lots of other data it becomes even more valuable. Also never forget, big corporations track literally everything. Why not add your heart rate.
Not everyone, just Americans and other surveillance states. I have no idea about Canada but probably you too.
Where do you live that you don’t think America is spying on you too?
America 😂 it’s at least theoretically possible to avoid American companies outside of America. In practice, you’re certainly correct.
Article is paywalled for me.
Does it describe the methodology of how they use the transmitter and receiver?
What specifically are they transmitting? Is it actually wifi signals within the 802.11 protocols, or is “wifi” just shorthand for emitting radio waves in the same spectrum bands as wifi?
Yeah sadly it is paywalled, but I have been lucky enough to get access to it through my university.
Heres what I found regarding your question in the article:
Fig 1:
<img alt="" src="https://feddit.org/pictrs/image/ec3b41c9-0741-4a3e-81b4-d1d0596fef54.png">
And this is the Setup they used to collect the ESP-HR-CSI Dataset (left site) and the one that other researchers used to collect the E-Health Dataset (right side):
<img alt="" src="https://feddit.org/pictrs/image/8f4e393c-1051-4090-a39c-fa1dc08fbb94.png">
The parts on how they collected the data:
To me it sounds like, that they really just used standard WIFI to collect the data (this is especially true for the E-Health Dataset), since all the processing gets done on the Raspberry Pi.
does that mean a passive observer can do all that observations? and that a raspberry pi, with its single average antenna is capable of this?
It may be possible, but I have no clue. It may also be, that the position of the router and the Laptop is important, but that’s probably something you would have to test.
All these Wifi for tracking people methods use the channel state information (CSI) that is used to help decode the transmitted data. CSI is obtained from pilot signals that are transmitted as part of a regular transmission. This is done in basically all digital communication standards, so you could do this not just with Wifi but also with 4G or 5G or older mobile communication standards. This is all not very surprising, there is a lot of research in contactless radio based heart rate monitoring, they usually build on radar systems not communication systems though. The buzzword for 6G for all this is joint communication and sensing.
Isn’t this no different then a sonogram
I am not surprised. Passive WiFi was introduced nearly a decade ago, so it makes sense that measurement systems based on WiFi have come a long way since. It’s frightening, honestly.
This is really cool and will be useful. My second thought was oh great now my smart TV can see how excited I am watching their injected ads and how many people saw it too. One of the many reasons to never connect modern TVs to the Internet.
The next headline will be “wifi connecting to internet-no modem needed”
Oh, the person selling you medical or life insurance is gonna love this…
One day, WiFi might even be usable as a method for making a reliable network connection
Just imagine how much humanity could benefit if sharing and accessing knowledge was freely available for almost anyone
is it not?
Depends on how specific the information is and how well it’s hidden among alternative facts
That’s the joke.
The problem is not sharing and accessing, but generating. If we had a system where people would be paid for generating knowledge, then they wouldn’t have to charge for accessing knowledge.
That’s why a lot more research should be paid for by the government. In exchange, government-funded research would be excluded from having patents and/or copyright.
Goverment funded research is paid for my public money via taxes but the research information is not publicly accessible, I can understand this if it’s defense or other secretive research but there is no reason someone should have to pay for access to other research fields information when it is publicly funded
One can dream. For now though it’s the one radio my phone doesn’t use. Mobile network tunneling through Bluetooth baby! My atrial fibrillation when remain between me and my meth dealer! Shout out to Craig!
Wifi sognals can read my heart rate, and be used to track me around my house. But I still can’t get a signal in my room one floor up from the router.
This is the key point - these have to be clear signals in the same room.
Hence wifi 7.
Care to elaborate?
Faster speeds, better connection, requires higher AP density.
Is this good? I can’t tell if it’ll just be used as one more invasive information gathering data points for Amazon and google
Is this good? I can’t help but think it’s just another datapoint for google to scrape
