Odd thing about Nexus One Multi-touch

I downloaded the visualizer app (the one with the 2 dots and not the square)
and yea if I begin on the left side of the screen then touch the right and move around the points hang a bit when they cross and will hardly ever switch (unless u do complex rotating action with both points but then the switch is periodic at best)
but if I begin on the right side of the screen, the points ALWAYS switch...always...
Interesting...does that mean it's a software issue?
I already KNOW this is the wrong section but I feel this is something that could benefit from the most viewed sub forum.
edit: starting from the right side, the points fix themselves when I do the same complex rotating action that sometimes causes point switch starting from the left. I'd record it if I had a camera, but yea.

none of the 163 (at the time of this posting) viewers have anything to say?
not even a "WRONG SECTION NOOB" (Despite my non noobishness) post?
sheesh.

wrong section, noob.

wrong section noob.

hahahhaha LOVE IT.
another interesting update: The previous results were on a Cyanogen Mod...
Using Modaco Desire Alpha 14 I get the EXACT opposite results...
Starting with a finger on the left side of the screen then the right side point switch is guaranteed...whereas starting with a finger on the right then the left point switch is non-existent.
I think it is entirely a software fault...anyone who knows anything have anything to say about it?

then again, the overall finicky-ness of it is probably just a flaw period...though I think it can be fixed with a software update due to the different behavior between ROMs.
seems to switch points at random actually...on the desire ROM especially.

still wrong section noob. haha.

It has been covered by pretty much all tech blogs on the 'net already.
Some think it is a hardware bug, and others think it's software. Who knows.
I don't think it will matter for most people, although I consider it a serious flaw if it is not possible to fix it with software.
And yeah, this might be the wrong section, but it could also turn into a dev issue. "wrong section, noob" was funny the first time.

yea that's why I put it here in the first place, I shoulda added [Think Tank] and then squeezed my statements there...def belongs in General though...any Mod please move there without any Snarky comments prior.

i 'll move it but with snarky comment : use edit button when you want to replay to yourself instead of creating two posts

I just tried that Multitouch Visible Test, and it does not always switch the dots. It is a little bit strange though, because it seems like the dots are just put on the wrong intersect of the red and blue lines. If it is a hardware malfunction it is a very weird one. Some kind of random mirror function.

Maybe its a problem with the app itself and nothing with phones.... comon now, I don't have a problem with multitouch and I think that app is horrible to determine a bad phone..
No offence people, but these issues everyone brings up on this phone isn't a issue at all... the 3g issue is network not phone, the wonky screen is from the wrap around effect, the multitouch issue is retarded.....
The only valid one imo is the dust...... everything else seems irrelevant

The multitouch issue is not app based, otherwise it'd be present on the Droid as well (where it isn't, infact Droid's multitouch is damn near flawless looking at that video and having owned one) Though it's not going to be an issue for anything I and many others current use the phone for (Browsing, Maps, Gallery, anything else that uses pinch to zoom) it will become an issue and may already be for multitouch games...From what I saw it seemed like it is likely software based due to the fact that on the Cyan ROM one thing happened in one order and on the Desire ROM same thing happened (and a bit more buggy) in another order.
But yea, about the 3G issue..I never had that either...in fact my 3G with my N1 is better than the 3G i had with my G1.

It may be just that There is different hardware/software in one vs the other.....
I still don't believe it will be a issue, I mean that app your sliding both fingers at the same time, and it only happens some of the time..... I don't believe there will be many games where your performing that kind of action, and even if so it don't happent all the time and may act completely differently in a game than it does in the app..... I mean, if it was a big deal we would notice it in the other pinch to zoom apps, I've tried on pinch to zoom to get it to do anything weird and it don't..... just saying, I don't think this video/app proves much....
Then again, who the hell am I.. lol I don't know shat like anyone....

In fact, N1 has only pinch and zoom multitouch whereas droid has native multitouch...
temperbad there are a lot multitouch app in the market which state that Nexus One is not supported due to its multitouch misfunction..
ping pong multitouch is one of these applications..
Propably it is a hardware issue.

Try it in the browser. Pinch zoom out, then rotate your fingers in a circle and continue pinch zooming out. Instead of zooming out, it zooms in.

I too have absolutely 0 issues with pinch to zoom and rotating, getting my fingers really close together, etc. 0 issues whatsoever.
I'm on the Desire rom though.
Anyway, you have to remember this has absolutely NO importance whatsoever unless you play a lot of games.
If you don't, like me (I have a 360, so I couldn't care less), you'll never really have an issue with this.

HD2 Multi Touch?

Sorry that I keep asking noob questions today! I was wondering does the HD2 have multi touch in Android? Dont really care about Windows mobile. For stuff like pinch to zoom in browser or games like Nova with need multi touch?
Thanks.

Pinch to zoom on browser, maps ect. Yes.. as far as the game Idk..

edit: never mind my previous post. forgot we were talking about android.
afaik multitouch on hd2 with android works pretty good everywhere. cant remember any games in particular, but it works everywhere else that it should work

runningdap said:
well, the answer is both yes and no...
hd2's captive screen allows multitouch, but because winmo is a really old OS they didn't really updated it so that it supports multitouch 100%.
On the other hand, if you run android on hd2, you can see multitouch working pretty good though.

Great thanks to both of you that is great to hear! If someone wants to tell me it works in games too I would be super happy. Not just Nova that was just the first multi touch game that came to mind.

multitouch works with newton cradle at least.

HD2 Does not support True multi touch. As you can see when you touch both finger on screen then when both finger on the same line your multi touch will freeze. USe market multitouch visulisation 2 to test it and you will know what i mean.

i think it assumes two fingers but more it doesn't work. does desire hd solve this isue?

Yes, the DHD is able to recognize up to 4 fingers and thus 4 different moves.
That's because of the built in clearpad 3000. It even supports up to ten fingers. But this depends on the driver.

Multitouch problems...

Hi,
how is your experience with multitouch on the HD2? For me many games with multitouch don't work correct. Multitouch zooming works, but also doesn't really really work perfect.
How is your experience? Is this a hardware problem of the HD2 as WM6.5 didn't support multitouch so this wasn't necessary? Or is this a driver problem that might be improved by other WP7 roms?

WP7 is designed for 4 point multitouch and the HD2 is only 2 point. Just dont put your fingers so close together.

For me it doesn't even really work with 2 Fingers. When I have a game where i have to press a "button" for right and another "button" on the other end of the screen to jump this doesn't really work...

you really don't know what you are talking about , how an os with 4 point multitouch won't recognize two points accuratly , it is just driver issue

[Q] HD2 Multitouch Issues

hi i have been have a very big problem with the multitouch on the HD2 running in android NAND the best way of showing this is using the app multitouch visualizer 2 which is free on the market its shows that when the touching two points on the screen when two axis become near each other from the vertical axis or the horizontal it will move both points that are being touched
is anyone working on this problem and if so are you working on more than 2 point multitouch for the HD2 android

You should post this in the right section Android Q&A

The multi touch is a known issue. There are debates on whether or not the HD2 supports more than two fingers also, but that is irrelevant right now, as two finger multi touch doesn't even work properly. However we also don't know if it is the HD2 that simply can't handle the two finger touch or is it the drivers.
Now iunno if anyone is actually even going to bother with the problem as the only times the problem is an annoyance, is during gaming, but that is, gaming with a joystick and etc. So I don't think devs are actually going to bother with a problem they don't even know whether its the device or software.

ah...
but since it only support two touch i think mine got a lil bit problem with 2 touch,
like it will get trouble when i am trying to put 2nd touch... like playing gt game, which im breaking it also react my steering that makes me unable to play it...
so it is cant be fix then?
thank for the information then

The hd2 can only support 2 touches, there is no problem with axis inversion , although when the two points are close to each other they lock and that is a hardware problem

No, can't be fixed. When the touch touches are near the same axis, they will both show touches on the same axis. Pretty sure it's a hardware problem. This is one of the big points I always tell people when they're trying to decide between HD2 and a native android phone, along with the fact the HD2 screen is only 56,000 colors compared to 4million a native device has.

well if it is a hardware problem can some one give me a link to a source that shows this

I'm not about to dig up old threads about the touchscreen driver development or irc logs... any of the devs that have worked on drivers for the touchscreen have said this. I remember seeing cotulla discussing it in irc sometime in the last few months. Touchscreen is not going to get any better than it is right now... there has been a lot of work on it over the last year and a half.

i resume this thread to notice that isn't an android issue... it happend on windows mobile also.. and is irritating..

There is definitely axis inversion and a few other bugs.

The Hd2 is single-touch and pinch-to-zoom.
It was never intended to have multitouch or android.

well... let this multitouch be for pinch to zoom only but this issue is disturbing while normal tapping on the keyboard.... You tap next letter of your word and You don't release the previous letter so this "next" letter won't be recieved. The touch runs between my fingers, look :

It is not single touch, it dual touch not true multitouch axis inversion is happening in the video as they are putting the fingers to code to the edge of the screen so its messing up.

Is the keyboard multi-touch? Many keyboards aren't and can only receive a single input at a time so even if you type really quickly, you need to make sure you left one finger completely off the screen before typing the next. I can type pretty fast using the HTC_IME that comes with multi-touch. I mean, you can't hit "shift+a" to get a capital "A" but you can hit a key before letting go of another key and the keyboard will still pick up the correct keystrokes most of the time.

Dual touch mode allows a two sensor system to track the absolute location of two simultaneous events provided that they are located in different regions of the screen.
What you mean is Dual Control or Gesture Input aka pinch-to-zoom.

When I was using MDJ_FroYo_Revolution_v._2.1_NAND, i think, Multitouch was doing well. There were no such thing like multitouch problem, even while crossing the fingers. Now I'm using BOYPPC-SHIFTPDA GINGER 2.3.3_V10 and I have problem with multitouch. I'm 100% sure that I was using some ROM with well working multitouch. Maybe someone should check it?
Sorry for poor English...
Edit: I was not MDJ_FroYo_Revolution_v._2.1_NAND. When i figure out, I will make a video for a prove.

where is the proof?

Umm I starting to think that i was dreaming... -.-'

Honestly i have no problems with multitouch either using Gingerbread .
There s a couple other things that are a lil quirky but nothing that would make it unusable

Touch screen quality compare to other handsets

I have been using the Atrix for a few months. Last week, I have accessed to a Samsung Galaxy S2 and have played a few games with it. The touch screen on the S2 is very accurate and precise. In comparison, the Atrix touch screen is inaccurate and sluggish, especially if you're touching more than 1 point. This has nothing to do with the 10 seconds timeout that Motorola implemented. It's just the responseness on the touchscreen.

Tell me if i'm wrong, but don't we already have a MOD for that called "Touchscreen MOD (8 points)"
I saw it in the Dev thread under various roms like Darkside and WetDream.
Try it out and see if it helps

Install 'touchscreen booster' in market and select 'Super Optimized.'
Seems to make a difference here.
