Here we go... A nice program... Just put more than one finger on the screen... it recognize them all!! (it does not create a swirl for each finger, but it takes the average of coordinates and locate the center of swirl there)
It means that diamond screen can recognize more than one point simultaneously... (i wish i am not wrong)
Wasn't that behaviour always the case for single-touch devices?
Yes, that's not multitouch. Average of all touch is the default behavior for many touch devices including touchpads at laptops.
If they had really put a Multi touch Screen into the Diamond so why isn´t it in use????

Not a good argumentation. They've put a lot of HW in the diamond that we'll probably never use (heat-sensitive buttons, accelerated 3d graphic i.e.)
what are you talking about...first of all OS has to support multitouch...its the same as you cannot use HW when you havent SW support = drivers...
....but if its multitouch or not I ll try it in the evening...
Is it NOT Multitouch. It's a simple Resistive Touch Display.
This is how it works... it measures the resistance between two layers, if you connect the two layers at multiple points, the result is a point in the middle of the connection points.
heeey fellow forum readers.... yea its me again
a nother question
When i am in the fish tab.
AND i put a finger in the top and in the bottem of the screen
the fishes go tho the middle of the screen
when i release 1 of mij fingers the swim tho the one thats stil on the screen
Is there som software that lets you use this multie screen just like the pictures on the iphone?
greetings and sorry fore my poor english
sorry but it has NOT got multi-touch, I dont think the screen tech (resistive touchscreen) is even capable of that.

edit: how do you delete a double post :S
That is not multitouch, the fish simply move to the "average" position of your fingers (the middle) then when you remove one finger, this "average" changes to the position of your remaining finger.
This is what happens with a singletouch screen.

but how can a single touch screen(i mean not mulitie)
can calculate the average of 2 points??
than it has to know that you have 2 fingers on it right?
and when i move the 2 fingers on the screen the fishes moves with it on the midle of them
sorry if i am missing somthin here
i amde a sammple sovie of it... and sorry poor qualety

First read this: http://en.wikipedia.org/wiki/Analog_resistive_touchscreen
Now, when you depress on two points, the voltage reading used to provide the co-ordinates is exactly what it would have been had you pressed in the exact centre of those two points.
The screen cannot tell the difference between you pressing on two points, and you pressing on one point that is located at the centre of those points.
If you operate the device with your thumb, it does the same thing - activates the screen at the centre of the point of contact, as opposed to the stylus which is much more precise.
I don't know how else to put it, apologies if it is not very clear
i've been puzzling over the multi touch possibility because when using ie/viewing emails, if i swipe (vertically) using a stylus it selects text, while if i swipe with my finger, it scrolls. hard to explain if the screen is simply averaging out the positions, isn't it?
Biotouch.exe is responsible for that behavior.
Xperia's touchscreen is single touch only.

Pages 2/3 of this document show the diagrams of a regular 4wire resistive touchscreen and how it detects the xy position. That should give you a more clear view on how/why it averages the way it does when you have 2 fingers on it.

Gestures aren't exclusive to to multi-touch screens. You can write software (I have done some of this) that tracks a movement across the screen, use fancy math to get the direction, and implement that gesture. Not very hard.
If the average of movement of the two points moves enough in one direction to set off a gesture thats what will happen.

Oh deer, i guess you're very, very wrong...
Multitouch is possible with the Xperia touchscreen - but the rest of the phone (especially winmob 6.x) isn't ready.
See here how great resistive multitouch screens are:
http://www.engadget.com/2009/02/19/stantums-mind-blowing-multitouch-interface-on-video/
There's some WM software that does the multitouch trick on resistive screens. I think it does it through some intense calculations though (CPU heavy). I'm sure it's just a novelty and not useful for anything.
My theory:
Detect the first finger press, the second finger creates the average, from those two values you can compute the location of the second finger. This is a lot more CPU heavy than just reading two values from a true multi-touch screen.

Hi, do you have any idea how Biotouch.exe (the program that runs all the time on our Xperias) tells the difference between a thumb/finger press/drag versus a stylus press/drag?
I'm speculating/guessing that when you use a finger/thumb, when you press down, it creates little movements constantly (because your thumb/finger isn't exactly flat on the screen, it creates tiny little movements as your finger pressure moves slightly around)?

I've wondered about that too, I first noticed it when trying to scroll an email with my nail, it selected instead.
My theory is area of pressure, a stylus would have a very specific area of contact, an thumb would depress a much larger area, it would take the centre of the area as the target, but be able to act differently.
Wow .. it really handles stylus and finger different !
Yes, it for sure is area size. You can achieve 'stylus' touch with fingernail too.
Then this is one and half touch screen .. not singletouch, not multitouch.
Old Palms had singletouch, and that technology can't detect center of touched area, nor size, it detects only lower-left (IIRC) corner of the touched area. Fine for stylus, but really bad for fingers.
Most touchpadts work just like this. They can detect upper left corner and bottom right corner of the touched area .. but nothing between it.
Anyway with this you actually can detect most of the multitouch gestures. You can detect 1 finger or 2 fingers drag (different area size), you can do pinchzoom (area size changing). I guess things like this would be possible on Xperia.
Only thing you can't do is using screen as gamepad .. which iPhone can do .. it can detect several areas (virtual buttons) with no interference at all.
What I experimented on S2U2 software with xperia,
is to test the result is it with multi touch capability, but i am not sure.
You guys can have an experiment.
1. slide the S2U2 slide with 1 finger with ur right finger to the right.
2. then using ur left finger to press the slide bar somewhere at your left.
3. Play around by releasing the your left and right thumbs to test is it multi touch.
I am not sure, please some one tell me does it shows any clue. thanks.
yea my theory is that the hardware supports multi-touch, but the software doesn't recognize them as two individual points but instead takes all the values (or coordinates) of everything that is being inputted and takes in the average instead. if this is true, microsoft should definitely start developing multi-touch capability on their future winmo platforms.
The Xperia X1 touchscreen is most definately NOT a multitouch display. Multitouch works by actually using an array of touch devices on a single panel. This is true for both resistive and capacitive touch panel technologies. The result is the multitouch have a great many connections to a processor. While single touch panels only use 3 to 5 connections. The touch panel on the Experia X1's touchpanel has a 4wire interface, making it a common single touch device.
It is, as speculated, possible with some calculations to compute a second touch point with a little trickery. This is limited to a single extra touch point and results in both points being inaccurate.

The X1's resistive digitiser doesn't support multitouch.
What you described (avg co-ords) is how resistive screens work. They can only detect one point. They have two sheets, one sheet detects X co-ordinate and the other detects Y (hence 4 wires- you can check this yourself if you pull apart your phone). Biotouch uses some mathematical trickery to guess whether you're using a stylus or a finger.
The X1 is not capable of multitouch.
Is it possible to calibrate the touch screen for use with the s pen?
When using the pen my note seems to 'write' about 1-2mm above and slightly to the side of what i'm actually doing.
Makes things like drawing even reasonably accurate shapes/lines etc near impossible....

My note also does the same and mine every note does the same and unfortunately touch cannot be calibrated in any android device(I may be wrong though)

have you tried changing the "dominant hand" setting under spen options in your phone's settings menu? if that still doesn't work try Touch Screen Tune from Market.....the developer also has a thread on XDA for this app as welll.
Sent From Galaxy Note Baby!
this is how to calibrate (read that several times in this forum and also works for me and other people:
enable auto rotate > open e.g. smemo in landscape view > draw sth with the pen and touch all the corners and edges with it > rotate back to portrait > now the pen should work accurately

I need to try this next time. When I had this problem I started the Note in recovery mode and wiped the cache. The pen then tracked fine again.
I am looking for a way to increase touch sensitivity on the S6 - like you can on the S5 - Note 4 - etc.
Cant find it - am I blind or is it missing? Normally it is located under "display" but I don't see the option there - Suggestions?
I don't think it's enabled. I'll look around and see what I can find. In the mean time you can flash @ktoonsez kernel. I believe he improves things in that area.
You having issues with your touch sensitivity?

Couldnt tell if you were making a funny or if you were serious.
What I am trying to do is have the option to use my stylus on the screen - not all the time - just sometimes - with increased touch sensitivity on the S5 you can do that - I would have thought they would have done this on the S6 -
anyone know if there is a way to be able to use Stylus on the S6?
Do you really want to increase the touch sensitivity? I actually want to decrease the touchscreen sensitivity of the S6. The touches is registering as swipe instead of single touch. Sometimes when I type fast it register as swipe. Want to know what I mean, download the app 9gagtv and try to click on the video cards to play the video.
I think the option is either gone or disabled because I couldn't find the option for it either
is it possible to disable the entire horizontal area with the front facing camera on it, so that you don't lose out on a portion of your viewing experience? kind of like the notch / no notch options in other phones
So to avoid losing a very small part of screen? You removen 3 times+ more screen? ? Seems counter intuitive

Like someone else mentioned I don't see the reasoning behind that, but you could possible use another launcher like Nova and have the permanent status bar across the top.
The justification is that one is more distracting than the other.
I'd rather take the hit and have a smaller screen (lose 0.2 of an inch) than have video gain 0.2 of an inch but be hampered by a pill sized cutout that obscures video. It is a massive distraction. Arguably worse than the notch because at least that was flush at the top.
The question is whether we have the opportunity to control placement in software. If so, is that native support in android or would that have to be a custom feature via different launchers?

I doubt it will be native support and it will require another launcher.

LOL, Thanks, good to know. That surprises me since that cutout was a Samsung feature and Samsung isn't big on hiding their features.
