the xperia has a multi touch screen - XPERIA X1 Q&A, Help & Troubleshooting
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.

Hidden Features Thread
Hi, I just thought I’d start a thread for hidden tips. As I’m sure there are many things people are not yet aware of that the phone can do. Here’s mine for the HTC Album. When zooming in using an clockwise circle, the size of the circle drawn dictates the amount you zoom in. A large circle covering half the screen will only zoom a small amount to the area encompassed within the circle. However, a small circle covering a tiny section of the screen will give you a far greater zoom into the section just circled. Give it a go...

Probably not a hidden featuere, but was new for me: When the phone rings and you turn it around onto the display, it mutes the ring. Very useful in meetings to quickly turn off the phone.

In the weather tab, tap on the left and right side of the 'weather' text to cycle true all the weather pictures... Not a big secret
A Program that proves Diamond has Multi Touch Screen!!
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????
LeoBeo said: If they had really put a Multi touch Screen into the Diamond so why isn´t it in use???? Click to expand... Click to collapse 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.
[APP] [updated] 4x4 Gyrometer/Inclinometer/Landmeter
Hello friends. I am looking for an application for measuring car x and y tilt for offroad uses with 4x4 vehicle. Only one suitable app I found is the Kai's water level with its gyrometer feature,but this is very small and in my case I don't need bubbles,so I want to get a software to do my job,but with much larger indicator,angles and warnings as this... http://www.youtube.com/watch?v=QegwIr4dle8 Is there anybody here,who can mix both functionalities of these softwares for me(cause I am not skilled with C)to one application? Super graphic effects aren't necessary. Thanks in advance.
Very cool idea. I found this http://sites.google.com/site/srlappsproject/home/on-the-level-app its for android but looks cool.
This is very ideal,but for iPhone http://appshopper.com/utilities/clinovintage

Click to collapse In truth that's not a difficult app to write, however, I think you'll have issues if you are planning on using it on the move, as the sensor only measures the gravity that it perceives, so if you move the phone around, it gets terribly confused as to where "down" is. I'm guessing you want to know that an incline of over x degrees is likely to cause the vehicle to tip, etc, but if you are bumping over rough ground, then you'll never get an accurate reading anyway IMHO. Cheers, Steve.
Well,I know,that the sensor reacts also for acceleration,because normally it measures inertial forces and the result is not depended only on the gravity. Anyway,it should be okay,because I need it for very slow motion of the car in difficult terrain and I want to see,if my tilt angle(especially to side) is in tolerance,because I don't want to flip the car on the roof. Are you skilled with this "easy" programming?
I would be happy to do the graphics for it just tell me what you need.

Click to collapse I wouldn't necessarily say "skilled", but I wrote the Touch Incall Screen Tweak which turns on/off the screen during a call based on the orientation of the phone, so I'm familiar with working with the accelerometer. Cheers, Steve.
Okay,I will prepare demo application tomorrow for PC. I want to have the functionality of the software in video,but with comparable graphics as Kai's bubble level gyrometer(visible horizont). It will be lonely one application of its type on the world,so you can be rich.
Maybe a little something like this. The buttons at the bottom would change color depending on the alarm setting for each angle. You could change that setting by pressing the corresponding button. The numbers in the buttons would give you the actual ° reading. Just a thought.
Ok, I pulled a stupid moment, there would only be 2 axis, Yaw and Tilt. I was thinking 3D
Also the Waterlevel app found here http://forum.xda-developers.com/showthread.php?t=411550 has the open source files posted with it, may save some time.
For me is enough to have just 2 axis. The front-end angle and side angle. The image posted before is quiet perfect,but we should have 4 buttons for X-warning,X-max,Y-warning-Y-max,when I hit one of them,I will be able to adjust it. Of course some notifications for these warnings are welcomed as well as angle value visible on the screen all the time. Next thing what is also welcomed is the power-on ability to prevent auto-dim/off the display. All the things should be visible from the driver's place,when the phone is fixed on the dashboard,so the fonts should be big enough and of course the calibration function to be present. With this picture you have saved me lot of time spended with programming the PC demo-now isn't needed,because all features are explained. Anyway,thank you for your help and willingness.
Something more like this? Then pressing the X or Y button would take you to a setup page that you could set warning sounds for yellow or red and you could also set degrees for the setpoints of yellow warning and red warning for each axis.
Quiet perfect! Can you enlarge the degree fonts and locate them to the bottom corners nearby the circle? Also the labels "Actual" are not necessary. Into the top corners maybe you can locate Calibration button and options/exit(if it will be fullscreened). The warning sounds is also not bad idea...
Like this?
Absolutely perfect!!! Well done mate. Now just make it working and it will be super. Are you able to make it alive?
Sorry I do not have that talent, wish I did.
Oh,what a shame. I'll try to take some developers here...
I think this needs moved to the developers thread.
Please, make this dream come true! I'm looking for this kind of software too!
[Q] Can Galaxy sense the footprint of your finger? [= pressure enabled apps]
Can anyone test whether Galaxy S software / hardware wise can detect the area touched by your finger? If this is possible then pressure related applications would also be possible. Imagine invoking a right click just by tapping your finger in a different way (so as to cover a greater surface) - the music / drawing apps / or GPS scroll speed in such programs or other (e.g. the greater the "pressure" the quicker the scrolling). Any ideas?
i highly doubt that this is possible and it is definitely not supported by the android api... edit: i just looked into the api reference and saw that android does support pressure for touch events. i have no idea however if the galaxy s does support this. i think i will try it ... edit2: sorry but i have to disappoint you, i always get the value 0.15686275 for the motion-event's pressure...but at least the galaxy s supports 5 finger multitouch while the htc devices can't even track 2 fingers right: http://www.youtube.com/watch?v=hVlsRCMltDg & http://www.youtube.com/watch?v=KRCDRXYJBCY
afaik this is only possible with resistive screens that report back the pressure, not with capacitive screens.

Thoughts on keyboard position on all-screen phones
After a week of using the 6T, I noticed that my typing wasn't as accurate as it was on my Moto Z Play. My thumbs also were a little uncomfortable when typing for a while. I realized that because of the screen extending further down the screen on the 6T vs the MZP, I had to move my thumbs much more down the phone than before. After playing around with the floating function of the Google Keyboard, I found a position that is more comfortable (image attached), and my accuracy has improved as well. The keys are now in a more natural position, lining up right next to where my thumbs fall when holding the phone. The other option is also holding the phone lower, thereby placing thumbs where the keyboard lies on this phone. The downside of that for me is that I have to shift my hands up and down the phone to get my thumbs to the top of the screen. Time will tell which solution I prefer. Out of curiosity, I wanted to see if anyone else who is coming from a phone that had a much larger chin than the 6T has had the same challenges. It may be also that I'm just getting old, and my hands are less flexible.
how do you make the gboard float like that? I can't seem to find it in settings.
raing said: how do you make the gboard float like that? I can't seem to find it in settings. Click to expand... Click to collapse Tap the g in the upper left, then the triple dots top right, look in the lower right?
This will be a necessity for me if I ever talk myself into upgrading my MZP to a 6T as well. My stubby, clumsy thumbs will have nothing to do with a keyboard all the way at the bottom of the device. Actually recently got rid of nav bar for gesture nav on the MZP, and this helps in that scenario too.
I just got my OP6T today and I'm pleasantly surprised by the phone. Maybe the screen is not as sharp as my previous U11 but the difference is quite small so I think I can live with that for now. The secondary thing is like the OP mentioned typing on the keyboard. I tried using the phone with gestures and even though its really easy to navigate around the UI, writing is just horrible. Space bar is so low that I have to hold the phone really low in order to right properly. With standard navigation bar everything is ok. Tried floating keyboard but its so weird to type and look down to see what you are writing. Also it's so funny that everyone is chasing the 99% front display ratio but at the same time interaction with the phone suffers a lot and we have to find ways to go around obstacles created but those almost full front display phones.
I use Minuum keyboard with adjustable spacebar height independent of the adjustable keyboard height.
