Virtual Scale?

[PDROID]

Im not really sure just how sensitive the screen is, but would it be possible to make an app the has the screen act as a scale, weighing whatever s on it??


Just found a post all about the way the touchscreen works

Would you really want to set heavy objects on you phone?? lol..

Well it could be used to measure drugs

thats more along what i was thinking he meant

but anyways to the OP:

no, there was one rumored to be out for the iphone a while back, just not really possible.

[rereTHEEbeast]

why.. jus wondering why yew wud want to weigh things

[AdrianLeon]

Not sure if your request is possible...

On a side note though, I use the 'Bubble' app to make sure my spliffs are level!

LOL

That would be awwweesssommmeeee. I dont see why it cant be made? & You guys, I dont think he meant a SCALE Like for you to stand on, a light weight sca;e.

If you don't see why it can't be made then you don't know enough about the phone.

The screen is a capacitive touch screen. If it were resistive you might be able to detect the amount of pressure on the screen and convert it, but it would only work on a very small range of weights. Either way, with capacitive touch screens, there is no pressure sensing since it just detects the electrical field from your finger. Thus the reason you can't use a stylus on it.

GasBot nailed it.

There is no sort of way to measure weight from the screen. It can sense if something is touching it, or if something isn't. It can't sense how hard someone is pressing.

Resistive possibly but also highly doubtful. It probably also works like an "on/off" switch. Some might have adjustable sensitivity, and you could weigh based on the pressure, but it still would have a very small range to where it wouldn't be useful.

Hmm, I don't think a resistive touch screen would be able to measure weight, since it uses the difference of resistance to measure how far across the X / Y scale the touch is.

For example, you press in the middle of the screen, and the resistance is half way between the minimum and maximum resistance of both the X and Y scale.

It's a nice idea, but with the touch technologies that I know of (not exhaustive!), it's not possible.
