application request...
 

not sure if this is the right place to post...if not sorry mods....i wanted to know if anyone knew of or knew a way to make a program that would basically turn your touch screen into a scale....like you put stuff on it and it weighs it by the pressure that is being applied....is there any possibility for this?

Re: application request...
 

what are you trying to weigh?:headbang:

Re: application request...
 

That would be an interesting app to see. If it were at all possible. From what I understand laptop touchpads are pressure sensitive to a point but not sure about the screens of the 6850

Re: application request...
 

this has come up before, but it went dead because what you would be able to weigh would probly be in small amounts and probly illegal and also too much n you risk cracking your screen, it would also be hard because youde have to have a "center of gravity" but again if its to much you crack the screen to little and it wont register

Re: application request...
 

Oh you silly little pot head. Or chef, he could be a chef guys. lol.

I would dl this app just to show off.

Re: application request...
 

It could be used as a postage meter for very, very small letters. Whatever you weigh would have to be very small since anything that you put on there would cover up the screen where it would be displaying the weight. :scratch:

Re: application request...
 

Does the screen even register anything past a touch?

Re: application request...
 

well you just have it set to show the maximum weight that was on there...like it slowly goes up to whatever weight and then when you take it all off that the number that is displayed....and this would be a cool app just to mess with...plus sometimes you end up in dire need of a scale when you dont have one....

if anyone could tell me or point me somewhere that would tell me how to i would try to make a program that could do this...

and as far as i know the pro's screen is pressure sensitive

Re: application request...
 

hey hey hey...just bc i need to weigh stuff doesnt mean im a pothead :silent:....but yeah im pretty sure we could just say this is bc im a chef and need to weigh out stuff when i cook hahaha :twisted:

Re: application request...
 

i would also like to weigh stuff ;-)

Re: application request...
 

btw....cnet reveiw says touch pro screen is pressure sensitive...

Screen - iPhone has multi-touch capacitive touch screen (changes voltage with finger, not compatible with standard stylus), Touch Pro has resistive touch screen (pressure sensitive, stylus included), but the buttons under the screen are capacitive. iPhone has 480x320 resolution, Touch Pro runs 640x480. EDGE: Touch Pro

heres the link...it was comparing iphone and touch pro....guess what....an app that no way in hell the iphone could ever use!

Re: application request...
 

The screen just does not work that way. In a nut shell resistive touch screens work by having layers, when you push your finger or stylus onto it causes those two layers to make contact. Then with some electrical magic the system knows where the screen has been pressed.

It does not operate by measuring pressure. So it would be impossible to make a scale.

Re: application request...
 

you sure it doesnt actually measure the pressure bc i know ive read somewhere that there is less pressure needed when using a stylus then when using your finger....wouldnt it need to know how much pressure is in that area in order for this to be true?

Re: application request...
 

I really don't know how to explain this properly but I'll give it a go. The tip of the stylus is smaller then your finger, thus it focuses the pressure in one area much better then your finger. This causes the two layers to touch each other.

Touch screens have more to do with electrical fields then pressure.

Re: application request...
 

this is an excellent idea for an app, instead of everyone wasting their time building 100000000000000 roms that r similar someone should make this useful program. make a toolkit, u can include a level app and ruler with the scale app. if anyone can do it its u guys

Re: application request...
 

but with advanced config you can change the sensitivity of your screen tap or something like that. i don't see why our screens wouldn't be able to weigh something with that option.

Re: application request...
 

haha i was thinking about this a couple of months ago. thought it would make a perfect little scale for a gram or 2 that would need to be weighed out (oregano). just for those times at the beach when some guys is like hey, i want to cook some pasta but i need exactly 2 grams of oregano to do it right. i could bust a maguiver, pull out my swiss army phone, and poof! 2 grams of cooking genious!

Re: application request...
 

Get one of these... It's only like 25 bucks.
Besides... Your product representative should have his Oregano nicely packaged in little baggies and weighed. You should have nothing to worry about unless you are buying at a non reputable establishment that is not monitored by the department of weights and measures... OR... If the oregano is actually being weighed by you for redistribution. Then I see why you would not want to have such a device in your "possession" lol.

Re: application request...
 

lol but these devices are so big and bulky, expecally when i already have a phone in my pocket. if the department of health comes in and i should feel the need to jog, i don't want an extra piece of equipment smacking my leg (haha).
