Multi-Touch problem in Nexus S? - Nexus S General

I found that sometime when you touch two points at the same time, the phone doesn't response as expected. The screen only detect one point being pressed. This happens quite often and I am wondering if it is my phone's issue.
You can notice the problem easily when playing "Slice It".

Multi touch is app dependent, some apps dont support it, open up google maps and pinch to zoom

Multi touch works fine for me. Nothing like the shennaigans of the Nexus One. Downloaded multitouch visulaizer 2 - my touch screen can detect 5 points of touch at once!
Edit - I see what you mean on sliceit. Sometimes if you put down 2 fingers simultaneously, it will lose the track on one of the fingers. All you have to do is lift that finger and put it back down again and it regains track.

I noticed that with Slice It! too and was messing around investigating it. Also, I think it's the app's issue, since I've never had any other problems with multi-touch anywhere else.

sound like more of a bug with some specific Apps rather than a hardware issue.
as the multitouch test apps works just fine, if it were a hardware problem those test apps should be failing as well.

I don't know if you guys remember, but when the N1 got its first update to enable "multitouch", there was a lot of speculation that it wasn't true multitouch as Apple has it patented. I wonder if they're continuing on that same track or whether Google said screw Apple and dropped it in anyway.

No. back then they used thinkpad2000 or something like that. forgot the same. wasnt real one " much like what Sony is doing with xperia x10" right now
the nexus s has true multi touch.

On the subject do any of you guys have problems with zoom in your photo galleries. When ever i try to pinch to zoom in for example to someones face it will start to zoom somewhere else. Don't know if its just my phone or everyones.

I tried to do the multi touch test using multi touch visualizer and multi touch tester. In multi touch tester, it only detect one touch point when i touch two points at the same time. In multi touch visualizer, it detect two touch points but the second point has a 1-2 second delay when i do the same test. I did the same test using Droid and galaxy s and they don't have the problem mentioned...any thought?

Slightly off topic, but in the Gallery app in the Album thumbnail section, you can two-finger press an album and spread your fingers and it'll give you a mini-slide show right there. Very impressive.

i never heard of a screen that has a multi touch problem as in hardware issue.
but try different nexus S. if its doing the same thing then your phone is fine.

Apple patented a specific method for implementing multi-touch... part of it is UI, which was only granted in the US, and part was technical... in either case, there are new ways of doing multi touch in technical terms, and as for UI Apple doesn't have a leg to stand on when it comes to "generic" actions like pinch to zoom, et al.

Some ppl in thus thread also experience the same problem. To me this is not a acceptable multi touch experience. I hope this can be fixed by an firmware update.

Update to windows mobile 6.5 and 7

Hello Xda
i am wondering are we can able to upgrade to windows mobile 6.5 in the future and windows mobile 7 too.
also can we will be able to use multi touch function on hd device?
Well on past models HTC have released new ROMs with newer version of WM, so you would think they would release new updated ROMs for the HD.
Unless they have another new phone on the horizon! You would think they would wanna sell 1 or 2 HD's first though before they release another 'high end' handset.

Yer was very close, I heard mixed reviews of the Diamond/Pro so held of upgrading, then the HD popped up on the HTC website so waited for the HD instead!
winmo 7 is said to have hardware requirement of 256MB ROM for the OS. so should be fine.
WinMo 6.5 will probably be less than 256MB ROM too so all go there too.
TOUCH HD should be well future-proofed for WinMo updates (official or otherwise), and then there's the possibility of Android too......
I think and hope that they will release at least an update to winmo 6.5 But I also think you shouldn't hope for Multitouch! If i'm not totally wrong the HD use a resisitiv Touchscreen and they are all not cabable of Multitouch, doesn't matter which Firmware is running
There is supposed to be a pre-WM7 release, not sure what else is included but supposedly it will have a better version of the IE browser.
I imagine this may depends on how much WM7 will be a change and needs adjustment from HTC. Like... what will be the touch 3D layer then ?
My bet is, the more we are expecting from WM7 as a breaktthrough in the series the less me may use it on this version of the Touch HD.

Actually, correct me if I'm wrong here, but resistive technology is able to detect multiple touches - and even laptop trackpads can too, it's just that there's never been any software developed for it, and the operating system has just been hard coded to ignore multiple touch points and averaged them out to somewhere in the middle of where touched.It's pretty much a case of trackpad and touchscreen designers going "hmm what about if someone touches with two points at the same time? Ah well, there's no reason for doing that, let's just average it out"
Now, more realistically speaking, what exactly is the benefit of multi-touch on a mobile operating system? Pinch zooming? The zoom bar on Opera seems pretty simple and actually easier to use to me! Anything else? New Macbooks use gestures for Expose (no use for that on a mobile), two finger scrolling (about the only day-to-day useful feature, but again useless on a mobile device with finger scrolling anyway!) Two finger rotating maybe (um, accelerometer does that for you!) so anybody got any more suggestions for making this gimmick actually useable on a portable device that can't do it better already?
How can you play an instrument like a keyboard without multi touch!
While such a functionality might be an intesting one, it also seems like a step backwards in certain aspects.
Single handed operation is one of the essential aspects of mobile phones.

No correction needed, this is 100% true. Touchscreens do not register clicks, or anything similar, the screen itself is nothing but a sensor. The screen sensor layer on the HD screen registers any surface part of the screen on which the pressure exceeds a given threshold and the output is translated by a driver into anything the OS uses for manipulation. Thus, theoretically, ANY touchscreen device can be multitouch.

Many of the more objective iPhone users have indicated that multitouch should not be overrated. It is nice for picture viewing, but in practical terms such as with a browser, it can be frustrating to see people zooming in to 100% with a swift doubletap while the iPhone users themselves are having to place two fingers on the screen, prevent accidentally using your nails, and having to squeeze/pinch until the page looks right.
BUT... I for one believe that more natural forms of input, i.e. a Keyboard, REQUIRES multitouch to function 100% intuitively. You simply do not need to release your finger from one key in order to press another, and a singletouch screen does require this. This causes lots of mistakes when typing too fast, you have to be over-articulate while typing.
Then again, I see most iPhone users typing with one thumb even when sitting down and holding the phone with both hands, because it's their first smartphone Not fair... WinMo pro's should have received this years ago
Oops I am straying from objectivity here...

Just another confirmation of this. Synaptics, the maker of most touchpads for laptops, released driver updates for laptops to include multi-touch pinching, gestures, zooming, and Chiral(circular) scrolling - These were for touchpads that could previous only do what WinMo does with multiple touches.
So, as everyone said, you're right. If the manufacturers wanted to, they *could* give us multi-touch, but WinMo doesn't have an implementation of that anyway so it's useless.

The real answer is: no you can't have hardware multitouch like the iphone. If you search in this forum, you'll find that some people are working on a software solution to be able to press 2 differentes buttons at the same time; But you wont get pinch zooming etc on Blackstone.

From what I've read it will be possible to get a 'pinch' effect but only when holding one finger still and moving the other, it won't be able to pick up both fingers moving towards each other though.

If you keep one finger still on the screen and move the other to pinch, the touch screen won't be able to differentiate whether you are pinching in (for zoom-in) or pinching out (for zoom-out), because it only see one displacement: the movement of the center point between the 2 fingers.
So if we can't distinguish zoom-in from zoom-out, how can we use this 'pinch' effect to zoom?

When the first finger touchs an X,Y coordinate is available... when the second finger touchs there will be an instantaneous coordinate displacement that does not include the intravening points and also with no cooresponding finger-up event... it should be possible to look for this programatically and know that you are in a two-finger style event... also based on the change and a knowledge of the screen size, the first finger point and the resultant two finger average it should be possible to determine point number two as well as the changing delta between the 2 points which will give you pince or expand when you remove your fingers and you get a finger up event... note it is true you will not be able to distinguish more than two fingers but I'm betting this is enough for most uses.
they made it possible on the g1
It's difficult but can more than likely be done, would be a fair bit of maths to work it out though. Difference between resistive and capacative. But you can use a stylus or wear gloves with the touch HD so it's a trade off.

The G1 uses a capacitive touchscreen similar to the iPhone's and the Android OS already had redundant coding for multi-touch capabilities, IIRC.
So all they effectively did was throw a switch.
For the likes of the Touch HD, everything will need to be coded from scratch.
limited multitouch IS possible on the HD - I took a video of it in fact BUT don't tell me it's not true multitouch - I know it isn't. In Windows if 2 points are touched at the same time Windows interprets it as a touch between the two points. If a developer maps a virtual key press between two 'buttons' then the virtual key will register as both keys. So no, there is no iPhone type multitouch but there are ways to mimic it. See these two postings and in the first one there's a video using an HD that shows what I am referring to:

Well not even the iPhone has 'true' multi-touch as it's limited to two fingers.

This bit's wrong though.
The limiting factor is not the OS, it's got nothing to do with Windows, it's because the handset uses a resistive screen.

Multitouch accuracy in games

Multitouch pinch to zoom is nice and all, but I mainly am looking forward to it in games to get the kind of experience the iPhone has been delivering with onscreen dpads and buttons. It's the kind of thing necessary to play Nesoid and others on the Nexus One.
There's a game in the market called ToonWarz Lite that tries to implement exactly that; the left side is a dpad and the right side is buttons and look direction. Problem is... it doesn't really work that well. It doesn't seem to track two fingers consistently, especially if the two touch points "cross" the same axis. The game looks pretty great, but control is still a mess in my opinion. I'm hoping it will/can improve.
Is this a limitation in hardware? SDK? Just bad design? Is it that clumsy on an iPhone too (I've never used one)? I know multitouch is supported, but I'm just concerned if there are still hardware limitations preventing it from working as well as I wish it would.
Android has supported multitouch for a long time. We're just now getting Google Apps w/ multitouch...that is all.
So to answer your question, the game's multitouch is poorly designed.

That's reassuring. Especially because in those multitouch demo apps (like MultiTouch Visualizer) the same problem seems to be apparent. Pressing two points near the same axis just seems to kind of stick and not register correctly. And it doesn't seem to react instantly, there's a delay before it recognizes the second touch point.
Does anybody know of an app that demonstrates it better, without the problems I've mentioned above?
Otherwise I'll just sit tight and hope for better implementation one day

The last time I looked at the source for MTV it was using the "old style" of MT where it would infer the locations of the two fingers based on the "size" of the primary touch. This was the closest you could get back on 1.6 which lacked the true MT APIs. Also, this method involved a heuristic to determine when there was more than one touch - I think the size had to go over a threshold before it would try to decode the multiple touches. All in all it looked a lot like voodoo to me and I wasn't surprised by how flaky the results were, especially when crossing axes.
In 2.0 they now report each touch independently with its own size and pressure. I was going to hack the MTV app to do true multi-touch, but I never got around to it. Did you find a version of it that is "True MT" or is it still the same old original version that was doing it the old way?

hd2 can't really handle multi-touch well? (compared to samsung or iphone)

sorry if this was mentioned before, but i cant seem to find any related threads on hd2 forum, anyways here it goes
does anyone else find the hd2 handles multi touch really poorly compared to some other smartphones out there? like the iphone and samsung galaxy s. this is especially obvious when the two point are close to each other in either axis, which is demonstrated by the video attached below (not by me!), although htc desire is used in the video, i can replicate the same response on my hd2 easily
so my question is, is the htc hd2 hardware 'imperfect' or is it the driver for the touch screen the one that is causing the problem, cheers
http://www.youtube.com/watch?v=hVlsRCMltDg
edit: forgot to mention, what i mean by hd2 handles multi touch really poorly is when the 2 touches are close to each other in either axis, the hd2 sort of just merge the two axis, although they are not exactly in the same line!
Ill take the hd2 off your hands.

It.s a known old problem on the HD2. It was a long hard debate that HD2 can only ,,pinch-to-zoom,,. HTC implemented the drivers to use the device just for pinching. There are some workarounds on WM 6.5 to use the MT (look at fpsece) but if you refer to android (games i assume) you will experience weird behavior on the HD2.

Dont see the problem personally, unless you are expecting three point touch. Trying one of the multi touch test apps in Android, it works fine... are you referring to the snapping when the points approach orthogonal? or maybe mixing it up with this: http://www.knowyourmobile.com/blog/326530/htc_hd2_leo_lacks_universal_multitouch.html
...which clearly is untrue.
Real multitouch?
HTC HD2 have Synaptics Clearpad 2000 - work only with two fingers.
So there is no chance to see real multitouch on HD2 :/
Producent page : http://www.synaptics.com/sites/default/files/Product_Brief_CP2000_01_0.pdf
HTC Evo 4G have new touch panel - Atmel MaxTouch mxt224 - UNLIMITED FINGERS!
@UP :
This videos don't show new drivers . It's practically impossible to write new drivers by normal person.
Even with 2 fingers MT does not work as it should, actually HD2 is capable only to ,,pinch-and-zoom,, (as i said there are some work-arounds but you can.t compare evo or iphone MT with HD2)

it works, thats about it. the biggest problem i've had so far is when the two touches are quite close on the y axis, e.g. using a multi-touch keyboard, when i type o immediately after a, sometimes the o is registered as k or l, because the os somehow merges the two touches vertically, so they seem to be on the same horizontal line (sorry if i didnt explain this properly, but i think the video i've attached above should make this clear)
One thing that I noticed when using MultiTouch Visualizer 2 (free on Market) was that touch point 1 and touch point 2 would flip when using any Nexus builds. It is most apparent when touching between diagonal corners. Desire builds will show the two touch points recognized correctly. If anyone is having problems with Nexus builds, try this out. It may be part of the reason for your multitouch problems.

i get this too if i type very fast only it happenes to me everywhere on the keyboard
the hd2 doesn't have the clearpad 2000 , i asked htc themselves , it is used in nexus and desire not hd2 , that is why we don't have the axe problems that they face , and the 2 point multitouch is a driver limitation as htc said to me

Atrix 4G- just two fingers multi touch?

I just tested the multitouch capabilities of the Atrix. It only registered two fingers? wow I have expected that it will recognize at least 4.....I don't play games on my phone so I don't worry too much but still it leaves a bitter taste...
You can't really use more than 2 fingers on a 4" screen anyway unless you have tiny hands.
Why would you ever need 4 point multitouch on the atrix to begin with... I mean of all the things to complain about this is the lame...

First of all. I wasn't complaining. I just wanted to test how accurate the multitouch is because I am a former N1 user and the multitouch sucked. It was more by curiosity that I tried 3 fingers. I had also a Nexus S and a MT4G and they could register several fingers. I thought that all newer touch sensors were multi finger enabled...
BTW I like my Atrix very much and the screen responsiveness is better than on my HTC devices that I had.
from the build.prop file, it says 2 max touches.
I tried to change the value to 4 but it still would only register 2.
wierd my Nexus S allowed 5
and htc desire HD allowed 4
i think newer screens would allow more, not that it matters
just curious
Is by brand is not HTC so don't expect the same I guess it does suck tho , oh well
I looked at the fixit site and they say it is the same sensor as in the Nexus S: Atmel mXT224. But this beast should have unlimited touch according to the manufacturer. Interesting maybe it is disabled software wise.
As a former N1 user, this touch issue is not important. What is important is it registers two independent touches and never confuses them.
Why is this important? Virtual game joystick and buttons. You will never use more than two touches for that.
Yes there are a few games or apps that can do more than two touches and it is disappointing to not have that enabled. But we will almost never notice this.

This has already been proven for the Atrix (that it treats multitouch correctly); read about it a few days ago on this very forum.

The Atrix has the same ATMEL multitouch sensor as the Nexus S, EVO, etc. So we know it can register at least 5 screen inputs at once. The apps you are using to test the multitouch input simply does not support the device (yet), and will need to be updated in order to for this phone to register multiple inputs beyond 2. This is simply a case of outdated software on new hardware.

The EVO would not register more than two touch points while operating on the stock kernel - and it was shown after rooting and unlocking the bootloader that there were two different touch panels - one that could do three points and one that could do 5.
So hopefully the OE kernel enables the use of the max number of touch points supported by the screen and it is just a matter of outdated software.
so far I have downloaded multitouch test, touch test, multitouch visualizer 2, and multitouch tester all from the android market and the results are always dual imput, not multi...
Am I doning something wrong is the fact that it will not register a third or more imputs... I thought we had up to 5 digit touch
Can anyone confirm or deny?
Thanks
more than 2 fingers, Apple will give u a hard time

Use the app phonetester. That is the most accurate.

Why would you ever need 4 point multitouch on the atrix to begin with... I mean of all the things to complain about this is the lame...

This is a terrible problem. I had to stop playing metroid zero mission on my old phone, because you couldn't press the r trigger, the up button, and the b button simultaneously, and you needed to (those 3 buttons when pressed shoot misslles up) in order to kill the boss.
has anyone tried some emulators, like snes or psx or gameboid? i wonder if it reconizes more than two touch imputs..??

Apple, Google and device makers have been embroiled in patent lawsuits since the first Android devices were being made. It still continues. If folks recall, there was huge controversy when I think the original Droid (or was it even earlier, the G1 maybe?) came out and didn't have multitouch in the US, but the international version did. This is why and it continues to be an issue.
What are you talking about... The ATT captivate with the froyo ROM does 5 fingers...
Galaxy s has 5 touch
