Not Iphone (3, Insightful)

Anonymous Coward | more than 2 years ago | (#36853876)

The Iphone doesn't actually do any of the work. The ink senses the chemical levels, and the LED's and filters read it off the ink. The only work being done is by the camera, which isn't really unique to the iphone.

I agree violently! I don't understand why Slashdot falls for such a silly thing. Just report about the actual technique instead. Slashdot really doesn't deserve its readership.

Though I haven't thrown anything or hit anybody, I adamantly agree as well.

I am so sick to death of damn near every mobile tech researcher and every media outlet of any form tying everything to the frikkin' iPhone for no damn good reason. I'm waiting for the headline that says, "iPhone wins Indy 500" just because some driver forgot to take his phone out of his pocket before taking off.

What do they think, that Steve Jobs will reward them with a free iPhone? Or is it that they all fell for the marketing crap that told them they had to have an iPhone in order to be cool, and now they are trying to repair the cognitive dissonance that comes from not actually becoming cool by continuously promoting the very thing that embarrassed them? Could it possibly be that Apple has inadvertently (or perhaps advertently) created the first marketing campaign driven by customer's post-purchase embarrassment and disappointment? Naturally, no one would admit to such. It would confirm that they were wrong and create more intolerable cognitive dissonance.

Admitting such a thing would be possible only for someone who was not in the first place a candidate to get caught in this marketing ploy. I call this iCatch-22.

I'd argue that it's simply the fact that iPhone-using kiddies are very vocal about it, and will vote for anything with iPhone in it. And/or "timothy" is in the above group.

I mean... I know *plenty* of interesting stuff done with other devices -- Like the N900 for example -- but it just wouldn't reach the same level of publicity. It'd be like "We just created this great tool to read tattool ink!" "So? You just threw together a few OSS libraries anddid some processing. Big deal?"

But on the IPhone... I guess it *is* a big deal.

Re:Not Iphone (1)

bsdnazz (114881) | more than 2 years ago | (#36855266)

When it comes to technology, most people are 'kiddies'. They just want something that works and it easy to use. They follow the script like any kiddie. Most people what something that works and does something useful - they're not interested in how it works.

An iPhone app that can read the ink is special to them because it's available and works.

If you need publicity and you can't figure out a way to make your product fight terrorists or pedophiles, then go with an iphone app.

Amorymeltzer (1213818) | more than 2 years ago | (#36856302)

I can think of two, very good reasons:

1. Brand recognition. The iPhone name is huge, and instantly recognizable, especially as the "cool, slick, hip" thing it has been marketed as. Saying "Smartphones can read tattoo ink" is boring and "Charges can read tattoo ink" can be confusing.
2. News people are here to attract you. No matter what your opinion of the phones themselves may be, there's no denying that iPhone breeds more interest than any other.

I call fan-boy on that one. It is not the job of a journalist to achieve or play to "brand recognition." That is, unless all that "journalist" cares about is page hits. The terms "camera phone" and "smart phone" are also instantly recognizable, especially among the potential target audience of such articles. Your sample alternative headlines are obvious straw-men in that they are intentionally devised to appear boring, confusing, and inconsequential. Much more appropriate headlines could easily have been chosen: "New Tattoo Ink Puts a Medical Test Lab Under Your Skin" See, no need to mention the phone at all. If you don't think people are interested in tattoos then you don't get out much. I would venture to guess that more people have spent more money on tattoos than all the iPhones combined. Finally, if the iPhone really breeds more interest (among the readers) then why are Android powered phones overtaking iPhones? Not to mention all the other smartphones out there. Crackberry, anyone?

As I have said many times, iPhones are simply over-hyped status symbols, marketed to those with money to burn and thus, clamored for by those without who wish they had. They are nothing but "buttons" (See "Witness," the movie, the scene where Harrison Ford is first putting on his Amish clothes.) "Buttons," by the way, that lock their owners in to the control of a megalomaniacle organ stealer. Sorry, but I'm not buying into that particular lifestyle choice.

Re:Not Iphone (1)

Anonymous Coward | more than 2 years ago | (#36854176)

So if the article title was changed to "Android phones can read tattoo ink for medical info" the same argument can be said?

Re:Not Iphone (0)

Anonymous Coward | more than 2 years ago | (#36868442)

should be changed to app phones can read tatto ink for med info. i gues the reason they are using the iPhone is that it will get the headlines and that lots of people have them.
so may be the phone will be available on the NHS / insurance now.
Oh no apple will patent troll your blood/body parts....

Good news (2)

This could be a boon to those that have to do the finger sticks. Also useful for those that are borderline diabetic, or hypoglycemic.

Even without the iPhone, this is really cool (4, Interesting)

Dynedain (141758) | more than 2 years ago | (#36853910)

This is a really cool idea.

The iPhone part is a bit of a sensationalist gimmick, but it is a quick and dirty development environment for handheld image capture and processing. Just add the LED array for the specific light frequencies needed.

The real story I think is the specialized ink tattoos that can change based on the presence (or lack thereof) of certain chemicals in the bloodstream. While it sounds like a fairly permanent solution, it could be a real blessing for long-term patients that need frequent blood tests. Gives healthcare professionals, as well as the patient, an easy way to monitor conditions without having to draw blood.

Re:Even without the iPhone, this is really cool (0)

Anonymous Coward | more than 2 years ago | (#36853958)

Depending on accuracy and cost this could be really useful to people who don't even have a serious medical condition to worry about, like athletes.

It they can do that why cant they do something more useful like make the change visual. Tattoo goes red you're in trouble with no need to keep
taking pictures of your arm every time. As simple as checking your watch.

Re:Even without the iPhone, this is really cool (2, Informative)

Anonymous Coward | more than 2 years ago | (#36854466)

Because human eyes are not precision instruments.

A camera measurable change under certain very specified LED lights (possibly only detectable in the dark) is relatively easy (and would not be that striking) compared to a dye which absorbed something prevalent in visible light to a very high level emitting a dramatically different light wavelength as a result and changing form active to inactive in a fairly narrow range of concentrations.

Consider that the first could be read by something like a light sensor + LED under a black sticky plaster and either fed to a gadget either through blue-tooth or a small wire if it was near by (eg hidden under a watch which doubles as a recorder). in the future maybe artificial implanted pancreases will be the norm but this allows the nearly same level of protection without the major surgery.

Dragonslicer (991472) | more than 2 years ago | (#36855930)

Maybe they're restricted by physics and chemistry? Just because they found one substance that emits certain wavelengths, that doesn't mean they instantly know what substances could emit any given wavelength under any given conditions.

Please, please! Make a tattoo ink that fluoresces in the presence of birth control. And tattoo all the women with the word "SAFE" on their forehead, visible when they walk in the bar under a black light.

Re:Even without the iPhone, this is really cool (0)

Anonymous Coward | more than 2 years ago | (#36854372)

ummm, for some values of "safe", I guess that works.

you'd better add shades of varying tones from minor to major STDS, and the really bright warning for penis severing tendencies. Oh, and while you are at it, how about a double check that "she" is a "she", and not a "shemale".

iPhone plug notwithstanding (1)

relikx (1266746) | more than 2 years ago | (#36853986)

this is another classic example of the further integration of technology into our lives, regardless of the device's brand name. However, I'm ironically reminded of Apple's infamous 1984 ad in the approach that a sense of cult worship exists in the uniformity (I own an iPhone, not a judgement). "We shall prevail."

It will balance itself out over time. :)

Level or threshold? (2)

PPH (736903) | more than 2 years ago | (#36854214)

According to TFA, the ink fluoresces in proportion to the level of chemical in the bloodstream. Wouldn't an ink (or series of inks) that begin to fluoresce at a set of levels be better? You would remove the attenuating effect of skin and losses in the illumination/sensor light path. Different skin patches would be tattooed with different level sensitive inks and the result would be a pattern that would encode the bloodstream level. The reading s/w would be dirt simple (possibly even read with an LED flashlight/filter combo and the naked eye). a two dimensional tattoo could encode a number of parameters, include some registration patterns with ink that always fluoresces to mark pattern corners.

This is all about chemical equilibrium (look it up); briefly: While each single sensor molecule acts as an on/off switch with two distinctive states, we can macroscopically only observe the sum of the states of all molecules combined at a given time. And while the state of each single sensor changes continually, the sum of these states remains the same at a given concentration of target molecules/ions and sensor molecules. Thus, we can only observe grades, not states.

Different skin patches would be tattooed with different level sensitive inks and the result would be a pattern that would encode the bloodstream level.

This principle works well in pH paper; but keep in mind that the change of one pH unit is a tenfold in- or decrease in the concentration of "H+ ions". You don't see changes like this in the blood level of glucose. ;)

But you're right in that the combination of different dyes makes for a more reliable read-out, e. g., to control for skin changes through dirt, sun influence, etc., which affect the absorption of different frequencies.

Not just divers.

Body builders, or anyone looking to keep tabs on some process in their body that is conducive to this sort of measurement. Hell, people trying to lose weight, adjust their diet. Women looking to track their fertility, either to bring about or prevent pregnancy... perhaps anyone on birth control?

It is a nice new tool, something so often hard to do, now could become relatively easy and portable. It still remains to be seen what is actually practical... but... it has a lot of potential.
