Hello
Is a pda screen pressure sensitive in such a way that it would be possible, in theory ,to use as a weighing scale with the right software?
Or am i just being silly?
If you want to make sure the dime bag you just purchased is up to par, don't use your TIlt, buy a scale!!! Geeezzzz, smoke some more why don't you
lol, you made my day
but the iPhone, it can do that
**edit**
to be serious, sure in theory. pressure is a kind of weight. it detects pressure till a limit is reached. proof of conecpt wpuld be: put 100 gr on the phone and see what pressure values u get, from that u can easily calculate the other values.
practical its nonsense. a phone isnt made for that. but i likethe idea to smash your brain with my polaris
I assure you my idea wasn't related to drug use in any way ,tthat would be another usefull application I suppose ?

lol that's funny, but not stupid question.. people tried to figure a way to have it read your finger prints but the screen isn't that sensitive to measure that.
it's obvious what you want to do unless you want to weigh jewlery? almost no one needs a scale this small unless you're measuring really small amounts but i recommend getting a pocket scale like mines for about $30 it's about the size of the touch. and yes i use mines for measuring my daily reefer diet.
it's not possible to do what you're looking for, but i think if it was possible it certainly would be really cool.
been discussed before, the conclusion was that it isnt possible, and the discussion descended into talk about weed and oregano
Rory
well who concluded it wasn't possible?
i don't care if it's possible or not, as i just brainstorm..
pressure eq weight and weight eq pressure.
isn't there a pressure threshold on the device? that is, pressure needed before it responds, which it does. if you have the pressure mathematics then you can figure its weight.
problem is, it would probably only work for some heavy objects.. if you try to measure a gram it doesn't apply enough pressure to the screen for a reading.
but, i think it's not totally impossible after giving it some thought.. it would be a total waste to even try to make it work
It will need 2 things... to know how many pixels (or some rare screen units) are being pressed and the area being pressed, that way you may get the pressure=force/area... and force=mass*gravity... the pressure may be related to the number of units been pressed, not the force measured, something like a density of pixels pressed, more weight more pixels pressed, also the area would be important... it will need also to know density of the object... well its 5:30AM and i'm still working here hehe

Is there anyway to use the touch screen as a scale? I mean is there a program that will let you measure the pressure your "finger" incurs on the screen? Now there has to be a way to convert that to grams/ounces. I would imagine that it would take a certain amount to even activate the digitizer and it could very well be the equivalent to a minimum of .5g and that's fine with me. An operating range from .5-5g would be optimal.
I just thought this would be very useful.
i believe that there is a point og g to activate
and thats if
a timer deside when the contex menu come about
normal touch screens even pasive digtizers on tablet pc's
only do on and off registration
active digitizerts on tablets though support preasure measuring

I believe it to be one of the ultimate applications because it transforms your phone into something completely different silmutaneously increasing it's resourcefulness as a digital "swiss army knife" for the modern world. What other application does that (short of a TV remote)?
Are you familiar with the force of 5 grams? I don't believe you are or you wouldn't think it would break your screen. I guarantee that you put, on average, at least 8 grams of pressure everytime you touch your screen.

Wouldn't all your Coke get stuck at the corners of the screen
haha u read the words outa my mouth ;x that would be gangster tho
Alternatively you could try making some scales into a phone.
Haha, i realize 5g is very light...But as mentioned above the only thing I can think of that would be useful to weigh between .5 and 5g would be some white powdery substance
Otherwise, if I new it was less than 5g, I wouldn't weigh it. Problem is someone might try to weigh something much heavier and yes, break the screen
Or I could replace and reinforce the external GPS antenna cover and make it a bottle opener also.
Or I could program it to emit the proper frequency to start my "keyless" car key.
Anyways, this is all just for fun, so, don't worry, I'm not trying to tweak you.

Oh, oregano! Makes sense with your screen name being Chef
A little more green? Smokin a little herb are we? Or are we selling?
I think we're onto something here. We need better touchscreens that can handle more force.
Imagine the perfect windows mobile diet phone which can tell you how much weight you've put on, find you a diet plan online. And order a pizza when it can tell you don't care anymore.
Who cares about fingertip scrolling when we finally bring the phone into the real world and make it fix other problems too.
I think a built-in stun device would be cool. And a personal alarm. A decent torch. A proper flash camera with a zoom feature. Maybe we make the zoom strong enough and big enough to take a person's weight. Who needs stepladders anymore!
I think a built in printer could help but needs to support full A4 sheets. Maybe it can scroll up and down a page until it's printed. And can we adjust the camera so it can act like a proper scanner? A portable colour photocopier is born!
I'll stop there but as you can see, the possibilities with this magical device are amazing!
LOL
i really think theres no such thing as ultimate application
i really depend on how this application will help your needs and so that way it will be very useful

It should of course be able to monitor ovulation, blood pressure, heart rate (full ECG), blood oxigen level, blood sugar level, prothrombin ratio and last, not least my need for coffee.
And my next SIP should read my mind. Voice control and T9 are a bit old fashioned, right?
I want a phone that also works as a lightsaber.
if you smoked the "oregano"
all applications you come up with seem ultimate
and all old cake leftovers taste like the best thing in the world
(or so i've been led to believe...)
You are better off getting to know your “oregano” and learn to estimate the weight accurately. Maybe if you would need this for “sugar” or “brown sugar”, weighting something under 5g’s would be in some use.

and why do you need to weigh grams on your phone?
I work at a nextel service center, and the other day a customer asked about the touch and told me his buddy had a digital scale application on the phone. Apparently turning the screen into a scale, dont really know if this is possible but thought I would ask here.
Thx,
Corey
dont believe so the touchscreen reg preasure or no preasure
so i dont believe it would be able to tell just how much preasure
lol what would you be measuring with said scale its weight tolerance would be very small
An app like this would rule. Especially added with clinical xpert...

Not sure if you guys are kidding but the buddy probably meant a ruler.
I just loaded up the new android os. It has a tool that shows a graphical representaion of presure. The harder you push the number changes. I dont know how to make that into something but hey it's a great start.

If you mean a scale as in a weight-measuring tool... it's possible to do so with a pressure-sensitive screen (not all touch screens are). I don't know of any commercial or freeware programs to do this, but it is technically possible.
Even if someone took the time to write the program, it might be for a single kind of phone, and it'll be totally inaccurate. A scale should always be a scientifically calibrated tool, especially for small weights.
If the customer meant a scale as in a ruler, yeah, there's a freeware app or two that does that. Some people do say 'scale' instead of 'ruler'. Here's three to choose from:
http://freewareppc.com/misc/pocketruler.shtml
http://freewareppc.com/misc/ruler.shtml
http://freewareppc.com/misc/pruler.shtml
Finally, I suspect that your customer witnessed some sort of weird technical demonstration software for a pressure-sensitive screen OR they witnessed a hoax similar to this http://freewareppc.com/misc/xray.shtml .
We obviously have pressure-sensitive touch screens in our Vogues... if you push with your fingernail, (making a smaller touch footprint,) you can select text... if you use your fingertip, it moves the whole screen... try it in PIE

thats because the actual digitizer grid that enables the touch can sense whether the area being pressed is small or large - this is not based on how much pressure is applied.

Thanks, you beat me to that one.
Pressure touch screen
However all you'd need to do is have a device that will translate pressure into surface area, something like a rubber thumb may be effective, the more weight the larger circle it "creates" on the touch screen, then scan the touch screen to see the current number of pixels being touched and translate that back to weight.
I imagine McGyver could do this with a paper clip ;-)

Sorry if I'm one of the many people that see using a PPC to weigh your drugs is the goofiest thing ever heard of !
By design the touch screen is a digital device, it measures on or off. It doesn't measure pressure.
If you want something precise there are many scales that use a serial port, all you'd need to do is interface the scale with bluetooth, there are probably some lab scales available that use bluetooth, haven't found from a quick search though.
it sounds like it would be near imposible to make it work
as the expanding rubber would have to be heavy enough
to activate the screen without any extra weight on and still expand
enough for preasure size to be measured without adding
more weight then the screen could handle without breaking
The thread is quite old but I think the original request is for scale rulers. i.e. for engineer to read an engineering drawings. Most plans are print out at an exact scale and it is a hassle to find the correct ruler for a particular scale. To have an app that can display a ruler at the edge of the screen at a particular scale saves a lot of time for an engineer to estimate a distance based on the drawing he's refering to.

Hi all
Just wondering if its at all possible to use the screens pressure sensor as a measuring surface? I guess it could measure light things up to 5 or so grams?

Ok it seems there is a bit of interest for the ultimate urban tool that will give the HTC Diamond the street cred it deserves. Therefore I’ve decided to professionalize the thread as humorously as possible
Below are the application details and status
Executive Summary:
The ultimate urban tool that will use the built in pressure sensor of the HTC Diamond LCD Touch screen to measure the weight of light objects down to 0.1grams.
Names: (Please feel free to add some names, I’ll keep updating)
1) Diamond Crystal Display
2) DiamaWieght
3) Ice Ice Weighty
4) The real "G"Sensor
5) .... more to come...

If someone can whip this program out ill PayPal them $15...its easier then carrying my scale around and i cant get charged with intent to sell if i dont have my mini scale one me
Help me out
**** ill paypal 75 no lie to anyone who can make this happen this weekend!
Haha i will use it and paid money to... max 15 dollars (thats what's left on my paypal account). This will be the coolest app ever made And verry handy for on the streets indeed.
Then You will not need a digital weigh in your pocket for your street bussines
hmm, don't think of it as very useful... It could weigh from about 4 grams to maybe 40 grams, regarding the fact that the weight has to be concentrated at one point and not distrubuted over the surface. The fact that keeps me holding back is that the result from weighing someting over 100 grams could easily end op in a sound and screen effect not coming from the program (KKrraaack with the screen affect of shattered glass)
lol, thats a funny idea
it sounds like a funny idea but dont think it will work
because of the difference in screenprotectors - some screenprotectors are thicker so you need more pressure, some dont even use screenprotectors (like me... BIGGGG MISTAKE! when i wanted to apply my screenprotectir my screen was already scratched! so i left the protector off.. but now i have even MORE scratches.. but oh well..)
just test it, turn your clicking sound on for you screen and hold your stylus at the very top and drop the end on your screen, you'll notice that you will not get any feedback, so maybe just like hellboy said mabye t would work from 4 grams
and your screen! it would damage i think when putting someting above 500grams (maybe even with lower amount of grams)
it could be done..
it would be fairly easy FOR SOMEONE WHO HAS THE PATIENCE AND THE KNOWLEDGE OF SCRIPTING APPS!!
because there are apps already that show how much pressure you're appying on your screen and gives you feedback in color...<<< i think that part is easy because i think there will be some snippets from codes around the net that do that.. but i think the hard part>>> is programming the ammout of grams that is put on the screen..

It would be useful for any jewelers who need to weigh stones and gold in small quantities, but the accuracy will need to be very very high for this kind of application.

I don't think your gonna get this kind of accuracy from a touch screen, besides I don't even think it will work!
A touch screen works by having two charged membranes over the top of each other, as soon as these membranes make contact it allows a voltage to pass through it. So how hard you push will not mean the voltage is increased and therefore won't make a difference.
Would be a sweet app though!
I had a debate with my friend last nite if it was possible or not. I say it is with resistive touch screens... Can someone prove me right? it only needs to measure oooh, say a few grams
Id imagine the only thing that would keep our TP2 from measuring weight is the lack of multi-touch.

LOL I think I can picture exactly the creative process and environmental variables that led to this question...I'm surprised that nobody else has had that same "hey...what if!" moment already
I think the obstacle here is that resistive screens generally can identify one 'peak point' of pressure, and can track it's movement, but I don't know if they could do anything with weight that is spread across the screen. So, you'd have to measure out...whatever...into something about the size of a thimble, but weighing much less. I'm not saying that it's entirely not possible, but it would have to be done some other way than just setting some substance directly on the screen (unless it was compact enough that it only created one pressure point...)
Honestly I'd really love to see this too. Not just for the obvious use, but also because it would be great to have for the next "yeah, well, can your phone do this" competition I find myself in
Can your phone keep your dealer honest? I KNOW there's not an app for that!

that same question was raised back 3-4 years ago when i had my tilt (1) kaiser. It would be handy at times such app...
Yeah, if somebody figured it out I'd pay them a visit shortly after harvest with the shiny kind.
that would def be a app to have! id show some love for a working version that could weigh up to 4 ounces(quarter pound)... with a changeable standard, grams or oz... mmmm.... what were we talkin about again? lol
haha, Seems like theres a real demand from the erm... "Community." The big question is it is possible on a resistive screen that DOESNT have multitouch? Devs, we're lookin at yous
http://www.xda-developers.com/windows-mobile/dual-touch-sdk-for-resistive-screens-v1-0-beta/
multitouch?
Yes we would all love multitouch and in the future windowsphone7 will support it. When I made the SuperMarioBros. for windows mobile it didnt support Multitouch which some people had problems with , but got used to it after a while. You would have to let go of a button in order to press next button. I look forward to multi-touch as I will be able to create games of more depth.
Disclaimer
If the phone does not pass this test it's definitely not waterproof!
If the phone passes this still is not 100% confirmation that your phone is definitely waterproof. The chance is rather high though.
Did you ever wonder if your device is really waterproof but do not want to find that out by dunking it in water?
Here is a test which uses just the phone and it's service mode (or any barometer app).
1. dial *#*#7378423#*#*
2. go to "Service Tests"
3. go to "pressure sensor"
4. slightly compress the phone using your thumb and index finger by pressing on the display and back
SLIGHT PRESSURE. No Berserker mode please! This is not a crush-your-phone contest!
--> if all seals are intact the pressure should rise. Your phone with intact seals is a closed system. If you compress the volume the pressure goes up as a result. If any of the seals is compromised pressure will not rise.
Note: pressure will decrease automatically - that is likely a result of some mechanism (membrane/valve behind lanyard hole) to adjust for changes in atmospheric pressure to allow the barometer to work.
credit for the original idea goes to User Alik from the German Android-Hilfe.de forums
Haha, that's kinda cool and a good way to reassure yourself before you do anything drastic.
I chose the 'go hard or go home' approach and the first day I had my phone I dunked it straight into the fish tank for 5 minutes and took pictures of the fish!
This is cool ?
Do i press on the ports? Pressure only seems to go up when i press on the display! Pressing in on the ports does feck all ha

No, you don't press on the ports. You need to reduce the internal air volume of your device, this can only happen by physically compressing the device. As the front and back panel is slightly flexible this is the way to go. Pressing on the ports will not do that as the frame is rigid and will not give.
High school physics:
Pressure = Force/Area
In this case the area is the air in the phone and the force is your squeezing. If you increase the force but the air cannot escape and thus stays the same, the pressure must increase.
If the phone was not airtight then the air would escape when you squeeze so Force would increase but Area would decrease proportionally and pressure would stay basically the same.
That is why this is a useful test.
Thanks for share brother.:good:
If you don't want to use the code every time there are plenty of free apps on the play store that show pressure: https://play.google.com/store/search?q=barometer
What a great idea. I have a Z1 that I suspect that back seal is compromised, so I'll test it later.
I did the test with my Z3 and it does works, even, if you open some port then the pressure doesn't rise.
Thanks for the info.
Out of curiosity, how much should it rise? When pushing medium hard, mine go from around 1005->1020 or so. So mine should be waterproof, right?

Yes that's fine already
Any one else getting a slight popping sound after applying pressure to the screen and then releasing it? Kind of like something snapping back in place. I'm not even applying that much force either. My difference in pressure is rather slight. A change from around 1001 to 1007. Since it was rising with all flaps closed and not when opened I figured it was good to go.
Mine goes from 974 to to 980 tryd the service and a barometer app. Are there any numbers which i can look up to be save bevore going for a dive

very interesting find!
My 6603 also has the same behaviour. I'm not sure whether this really is a defect and the point of water entry for your device. It might be a membrane/valve to account for pressure buildup, i.e. when the phone heats up due to heavy cpu stress.
You could start a poll to find out if every unit has this.

Considering the number of people who have this behaviour, I'm suspecting that this is functioning as designed, rather than a defect, and is probably an automatic air pressure equalization valve, something you would need in a waterproof device. Mine does this as well. (D6616)
Just to clarify, I don't have that unit. I have the D6708, the Z3v. Basically the Z2 chassis with no wrist strap holes for leakage.
So it should maintain the higher pressure if you keep pressing on the screen? I have the Z3v and if I push down on the screen and hold it pressure goes up but drops back down to the baseline within a few seconds. Waterproof or not?
Actually i tried the test and it does rise but when i place my finger to close the lanyard opening and do the test it rises more, that really concerns me. I submerged my previous xperias before without using this test before. I'm not sure if i could do the same with the Z3 after knowing that there maybe a design flaw in this line.
