Digital Scale Application?

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...

I assume something you only need a gram or two of...

there had been rumors also going around tht this was out for the treo 650 back in the day yet i was never able to find it

Ruler?
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 ;-)

Clever. I've seen that concept used before, but I'm not exactly sure where. It'd work, but accuracy would be an issue.

If someone can make this app, that would be awesome! Then I could do away with the scale in my bathroom, and weigh myself on my Touch, WTF?!

WOW! Thanks for the pointless post. If you dont understand the conversation then dont waste our time with your obviously simple narrow minded thoughts. You need to get out more.
It's to weigh things that only weigh a gram or so.

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.

another one bites the dust... good bye xperiancers... :(

guys. it was pure JOY to be an owner of SE Xperia, but enough is enough. I just got another cracks so I've decided to let it go and got myself new htc hd2.
seriously, typing in landscape on it is not that bad and comparable speed/accuracy wise with that not so perfect x1 physical qwerty. btw... speed. snapdragon. do I need to say more?
anyway... I guess no x2 for me after what I've seen on videos. no n900 either, even if I was considering getting one. x2 is daaaamn tooo slooooooww (seems to stutter even more than x1) and n900 unfortunately is a one big bug and shortcoming.
wish me luck...
see You on other parts of the forum. bye...
BTW: anyone knows what've happened with orelsi?? I almost miss that crazy bugger always knowing better... maybe his xperia finally cracked and he commited seppuku?? lol

lol good luck with your hd2, im thinking of buying one myself as a second device
btw, i too was wondering what happened to orelsi lol, havent seen him around here for a while, let's hope he aint clocked out

Well always good luck with the device you wish beeing the best for you.
Capactive screen is like seppuku for me,
As for HD2.
Actually I wonder more and more often what will I do in the future.
Even considering that I'll get my X2, I assume capactive will become
a ****ing tendency soon.
In this case I don't imagine using TouchScreen anymore!

well there will be two of us ... i hate so much capacitive ... but there might be some explanation for this ... my hands get really wet often and touching with the sensitive part of my fingers and swaping around gives me the nerves so i always touch the screen with the nails or top finger ... and not to mention the stylus problem ... I hope there are more people who dislike this thing... Ive heard there are also screens hybrid ... capacitive and resistive screens around.
And what the hell ... I dont get it this finger typing is by default non precise how can you make objects so big that you can use only your finger in such a small screen ... Web pages are not so big and with buttons there are also links ...
This is all Iphone fault

the snapdragon really makes a big difference in the speed and performace compared to slow x1 doesnt it??
i too dumped my x1 for a snapdragon phone. the lower-profile acer s200. lol. (hd2 a tad too big for me).
now i can watch hq wmv videos with no stutter at all.

i was looking at that phone as a replacement but just cant afford a new one when the x1a is still fullfilling my needs.
good luck with that phone, looking forward to reading your xperience (pun intended) with the hd2. hopefully next year i will replace my x1a with the hd2 or maybe an hd2 pro in the future.

well... still here. waiting for hd2 (delivery on monday, great deal with o2).
do not get me wrong, as I am not trying to convert anyone to hd2, but this whole need for resistive screen and real qwerty is becoming less and less obvious for me.
capacitive screen, read - toughened glass, hard to scratch, forces companies like ms to improve ui on their systems. see... the only good uses for styli are handwriting (are You handwriting with Your mouse on a pc?) and drawing (again, are You so much better with drawing using mouse on a pc comparing to sketches made with finger on a capacitive touch screen??). imho multitouch is more important than stylus.
qwerty... well... again - do some tests as I did. spb keyboard 4.1.1 trial, landscape fullscreen with clicking sound for better typing feel. I couldn't believe my eyes, as it wasn't much slower (if it was at all) or less accurate.
all I'm going to miss is xperia's still shot quality. some pictures shot in daylight are comparable quality with real cameras, and not those ****ty ones.
... but hey. I won't have to convert videos anymore.
anyway... I will keep my x1 as a backup device and I'll come back in here to share my hd2perience from ex x1 user point of view.
btw, I am not beeing paid for it.

i am torn between the HD2 and the X2
X2 = slow and keyboard
HD2 = Fast and no keybard
But i am so tempted to get the HD2 - to be honest i cant ever see my self using like the tilewave etc on x2 >.<

yeah... spb ms 3.5.x and manila are mos def better option than panels. have You tried that test with onscreen keys that I mentioned above? this and a visit in local o2 shop to get the feel of it convinced me to give it a go.
the last thing I was worried about was the lack of d-pad, but... honestly I do not play games much. other thing is that with recently hacked multitouch api apps like fpsece could use it in the future for virtual onscreen pad.

that would be really funny if it were true.

I think I might upgrade to a N900 after I save enough money - the X1's reception issue is a nightmare, even after testing 8 radio versions. At least with Nokia there is assurance of reception quality - what use is a smartphone if I can't even access 3G?! Or any thing except for WiFi, for that matter. Reception is sporadic at best, and at worse it doesn't even pick up a signal but my Nokia does display full signal strength...

Well exactly my points.

I am not sure why everyone so upset with X1, except for kinda wimpy 7200 chip.
I like keyboard, and don't really care about resistive or capacitive touchscreen. I am fine with either.
The one thing I don't use that much, but I am certain I would greatly miss is the physical keyboard. I don't think I am going to switch until there is a full keyboard on a snapdragon.
The cracks that everyone complains about are really just a cosmetic issue, and I don't really care too much about it (although I did re-shell my phone to make it black).
It is always kind of interesting to me the various types of devices that people decide to get and why. For the most part I understand each individuals reasoning, but I am yet to be swayed that there is a better device for me.
If anyone knows of a full QWERTY hardware keyboard unit with a snapdragon that is on the horizon PLEASE let me know.
Also, I miss Orelsi in a weird way. I suppose it was just his belligerent insistence on his perspective. I bet he got an iPhone too,
EDIT: I forgot about one thing that greatly aggravated me (although I had same problem on Kaiser) was that the keyboard goes bad and needs cleaning. Because of that I reshelled because I figured if I am gonna tear it apart anyway I might as well make it look like new.

actually there's one announced quite recently,LG eXpo GW820, 1 Ghz+qwerty,plus finger print security and a detachable projector as an optional accessory. it was initially announced for the american market and didnt mention european market,so we shall wait n see.
you might also want to keep an eye on toshiba n Acer as well,since they both got on the 1 Ghz ladder pretty early but havent make it go with qwerty yet.
btw,I am on the same boat with you, just want a decent processor with qwerty win mobile, not fussy about how advanced the bloody touch screen is going to be whatsoever...

ok guys. I just got it.
wow... that's all I can say. all You nonbelievers go to Your local mobile phone stores to have a look. bit too large, but I'll get used to it. speed... omg, I never knew that winmo can be that snappy. it's so iphone 3gs fast and smooth that I think I'll jizz in my pants. (http://www.youtube.com/watch?v=4pXfHLUlZf4)
one last thing, try it, and forget about anything other than snapdragon. seriously.

Yeah, actually I knew of that, but I am afraid of leaving XDA, so I guess I meant an HTC-based device with physical QWERTY and snapdragon
Nothing in particular against LG, but I am not sure I want to deal with their ugly iPhone-like interface.

Iphone 3gs screen also shivers like hd2

today i tried my friends iphone 3gs screen i zoomed a picture and moved my fingre on the screen and then stopped with my fingure still on the screen ,the iphone screen begens to shiver like what is happening on hd2 ,much more less but it shivers so i think this is a common capastive screens issues . i will post videos when i meet my friend again and take video of his i phone as this issue does not always happen

any comments to confirm or else

I get that too - and the sensitivity of the screen and whether it works is also affected by where I stand, and on what materials.
Tried to use HD2 next to refrigerator+light system today and an internal communication transmitter and the screen just wouldnt respond until I walked a couple of feet away - coincidence??? perhaps, perhaps not.

i get the shivver more when i use my finger tip instead of the finger pad. I suspect it is to do with the conductance being different on the tip.

i just sent mine back for repair because of this! in the cold screen jitter got so bad i couldnt select links whilst browsing! lets hope they loose my phone so i get a new one! lol!
sometimes i wish there was a decent alternative to HTC

has anyone noticed that shiver on i phone like what i noticed on my friends one

That's a common "issue" with all capacitive screens - including the iPhone's of course.

yes, i shouldve said that i first saw it on an iphone2G.
I think it is less noticeable though due to tighter spacing of the dots or just simply that it is a smaller panel...but it's still there.
Perhaps 4.3" is a bit too big!!! lol

good news that it is not only hd2 issue ,i was going to send my hd2 for repair

Id be interested to see a video of the HD2 and iphone doing it as i cannot make my HD2 do it at all??
Capacitive screens work with electrostatic fields in my understanding, maybe peoples electrostatic field who experience this is somehow different?? Who knows.... ??

i think all hd2 has the shiver screen but it depends on your finger position on the screen

I've found if you hover just above the screen it is more likely to happen. Or if you have another finger very very close to the screen and touch with another it gets confused.
But tbh I have it rarely.
BSB sensitivity tweaks and those in HD2tweak eliminated the issue for me entirely.
Another trick is to use a screen protector which makes it behave much more like a resistive screen.

Digital scale?

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!

Great information!!

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.

[Q] Is the touchscreen resistive or capacitative

I've been thinking all along that Nexus 7 would have a capacitative touchscreen, like all modern quality tablets. Never did it cross my mind it could be the resistive, more crappy, kind found on many low budget Chinese tablets.
However the UBM TechInsights teardown threw off alarms on my head by showing two resistive screen controllers:
ELAN Microelectronics eKTF3624BWS – Controller for Resistive Touchscreen
ELAN Microelectronics eKTH1036BWS – Controller for the Resistive Touchscreen
Can someone already with the tablet confirm which kind it is and report back? I think a simple test is just trying to use the back of a regular pen.
If it works with the pen it's resistive, if not it's capacitative.
Thanks guys!

One thing Google DEFINITELY didn't and wouldn't skimp on is this.
Don't worry, it's a standard touch screen. Trust me, if it was resistive you'd know. The internet would be up n arms, and this tablet would NOT be successful.

Thanks elcapitaine, but after the MHL saga I'm hoping to be sure of this. The reviews have told us surprisingly very little about the the hardware side of things.
I was re-reading the Verge's review to see if they picked up anything and noticed this: "To my eyes, this is definitely a software problem, but I didn’t see similar issues on the Galaxy Nexus with Jelly Bean, so this will remain a question mark. Simply put, sometimes when you’re scrolling quickly (say, on the homescreen), the scroll will not follow your finger, and instead snap back the page to the one you were trying to move away from."
So users may be assuming that any inconsistent behaviour is down to software glitches, when in reality it's the touchscreen itself.
I'm really a bit worried about this.

i can absolutely guarantee you that it's capacitive.
if it was resistive then we would know from engadget, verge, ign, or one of any thousand blogs.

Can anyone now confirm this since it's actually out now? Saw some apple fanboy going on about how the N7 had a touch resistive screen on a blog at Engadget, but couldn't find much either way on the net. Can anyone do the pen test?
Because as much as I want the N7, a resistive touch screen would be sufficient to make suffer using this POS iPad 1 until the next go-around.

It's capacitive, this isn't 2002.

Lmfao I don't think you know how hard resistive screens are to use.. They're **** and have crap multi touch.
OF COURSE the N7 is capacative, it'd be worthy of the garbage bin if it wasn't. Even $100 Chinese tabs are capacative these days.

Lol. I know exactly how much a pain in the ass touch resistive is, thus my disinclination to purchase the N7 IF it truly did have a touch resistive screen.
Though I admit that TR screens have come a long way since we all learned to hate them on the early palm devices. Most of our high-end drafting tables for our engineers at my company use TR screens, because there are some legitimate benefits to having a resistive screen over a capacative screen when you're drafting. But I definitely don't want one on a tablet. At least until palms new TR/TC hybrid screens start gaining traction. I think then we'll start to see some neat haptic screen techniques that weren't possible before.
But thanks for assuring me the screen is TC. Think I'll purchase my N7 now (though I'd kill for a 3G variant...).
