Hey guys wondering all these Rom makers or Google/htc made any multi touch fix?
With all the custom kernels and open source roms, has any developer attempted to fix this issue?
Would like to play games without on screen keyboard issues due to multi touch, this also affects typing fast.
Thanks
Hardware not software please do some research
Thanks. So does the s-lcd have the same issues?

the type of screen does not make a difference its the bit that lets the phone detect touch that is the issue here.
All HTC devices detect only one touch, and then detect the "size" of that touch which allows it to have pinch zoom when it detects a change in the size.
It cannot detect 2 individual touches.
please delete

Wait a minute, the Desire does have a basic multi touch digitiser... pinch to zoom in the browser etc. proves this. The EVO guys have developed a multi touch keyboard fix btw

you obviously didn't read what I just posted then.
It cannot touch 2 different touches at one, it detects one LARGE touch when two fingers are on, and then when you "pinch" it detects the size of that LARGE touch getting bugger or smaller.
Search for "Multitouch Visible Test" in the market.
That is an app for displaying the detected finger touches.

the desire dosent have multi touch, but dual touch instead, the issues people are having with games is beacause the desire gets confused When two fingers are placed close to each other or they cross the same axis because the data points get flipped, this is because of the way dual touch works, When you touch the screen with two fingers one by one, you get three points of reference: 1) Fixed Point – location of first finger, 2) Real Point – hardware detection point when two fingers are placed and 3) Fake Point – location of second finger. Interestingly, the hardware does not ‘know’ about this position – instead it is calculated by the application.
Is this translated in a hardware level or just driver?

ok then, sorry
And as mentioned you are wrong, as the desire do detect 2 points/fingers. Any multitouch test app from the market will show that.

no, what we have said is correct, the apps show an output but its not true multitouch.
All you have to do is try any multitouch app and do a google search to see all deivces up until now (after desire) made by HTC have dual touch, not multitouch
basically speaking it can detect certain multitouch gestures but not everything.
well i can play sonic and a load of other games and snesoid on the genisoid with run and jump buttons together, which tells me it's at least dual touch, to be honest the screen isnt really big enough to get 3 or 4 fingers on it properly and see what you are doing anyway
I will record a video of the hardware limitation of the touchscreen in HTC Desire.

or just search on youtube, loads have been done already.
I am not on about the lack of multitouch, there is a bug with two points with two near x, or y, axis points; they join together for some strange reason.
Link to video: http://www.youtube.com/watch?v=noQBUDy-WCQ
This is why multitouch keyboards dont work and there are problems with the PSX4droid emulator when having both dpad and control buttons on top or both on bottom.
I read somewhere that there was code in Android for a that filtered the Droid's multitouch results, that results in the Droid not having the axis flipping issue (does still have the sticking issue when close). Is there any way this code can be implemented on the Desire?
I think a developer called Phhusion on the Acer liquid forum in Modaco solved this software wise.

Hi guys, ever since I updated my Desire with Froyo (OTA) I've experienced a "bug" in the "dual-touch" that the Desire has.
The problem is when you are dual-touching and hold the first finger absolute still and remove the second one, the touch of the second one stays on until you move the first finger.
Which isn't a big problem until you play a game where you have to hold one button and steer at the same time.
Link to a crappy video to show my problem: http://www.youtube.com/watch?v=3eLYfHGeFnY
Now to my question, is it only me who is experiencing this kind of problem? Could this be fixed with a bakground app that checks the touch screen (when the second touch leaves the screen)?
/Oggeh
Same problem, i think is "normal" for the desire...isnt a multitouch screen..is an emulation and of course dont work properly..
Sent from my HTC Desire
But I don't recall the Desire having that problem before Froyo :/

the desire dosent have multi-touch, it has dual-touch, basically the way this works is, the desire's screen can only physically detect one finger touch, when you touch the screen with a second finger, although the desire can detect that a 2nd finger has touched the screen, it dosent know where that 2nd finger touch is, it then uses a mathematical algorithm using 3 points of reference, to work out where the 2nd finger is ..........

ok this is problematic in FPS games and games like meteor blitz
something i noticed though, on my previous amoled desire i had the official screen protector installed so i never noticed the problems in games
now on my new handset still unprotected, multi-touch games struggles a lot more
can anyone else confirm if their experience is better with the screen protector?

Even though I didn't notice this kind of bug before Froyo update? I mean, did someone experience this in 2.1?? Before Froyo it was possible to play games, emulators etc.
And yes I know that the Desire don't have the best touch sensor.

yes it happend with eclair, its because, imagine when u touch the screen with one finger, the screen detects it yeah? when u touch it with the second one the device see's it as one big finger touch, and then uses its reference point to work out where the 2 fingers are, now when u take one finger off again, because the first finger is still touching the screen it dosent realise because it cant phyically distinguish two fingers if you get what i mean lol

Isn't that just the common axis bug?
hello
i have a wird bug on my touch screen and i want to know if it is a general desire bug or a probleme with my device that i have to send back for repair ?
on magikmarker app when i press two points very quicly, my desire draw a line.
http://www.youtube.com/watch?v=pMyN822idH4
i thought maybe the app works like that.
so then i tried with swype and slideit
and there is exactly the same problem :
http://www.youtube.com/watch?v=gaPxeUqnCBc
anybody have the same problem ?
Thank you
This is a bug with all desires. They don't support true multi touch so glitches like that happen. Look for videos about desire multi touch on the YouTube.
Just tried it on mine and i don't get any lines.
not much more i can say on that really
If you get apps like visible multi touch test and use two points this will happen when you cross the axis too. The touchscreen can only support one touch. It uses an algorithm to work out where the 2nd point resides. HTC fixed this problem with new digitalisers in the stood incredible.

Ok I believe you but how come I can play games like NOVA fine using both my fingers at the same time if multitouch isn't supported? There must be some kind of multitouch or it wouldn't be possible.

He just told you how it works... You quoted his post with the answer...
Multi touch works but it's a very poor basic way of using it.
Desire doesn't got true multi-touch, it got half assed dual touch, and I couldn't play NOVA correctly because it wouldn't shoot when I wanted to if I had had my thumb on the joystick . Its because of the panel it uses and not because of software, so this is a hardware "problem"(Technically not a problem because HTC never advertised multi-touch, only pinch to zoom). Desire HD/Droid Incredible/Evo 4G uses newer and better touch panel with proper multi-touch.

It seems that the desire won't be supported, but I hope that list is not final.
There are very similar devices (eg. HTC Incredible) so maybe they just forgot about the Desire

I think we'll see an update, just not the full feature update. Same as the Nexus 1
I think the 3D tilt view will not be fully supported on the Desire/N1 due to the multi-touch issue. The main thing is the offline caching and we will get it.
Ye only thing is the multitouch bug that will make some of the tilting quite difficult.
Yes the Nexus one and the Desire have a poor Touch Panel, so altho it will get Google maps 5 You won't be able to rotate the Maps with a gesture (Although it SHOULD be able to do a pivot gesture according to its specification), The Droid incredible has a different Touch panel, which although still only Dual touch, handles that gesture fine without buggyness.
There is no "multitouch bug", the Desire supports pinch to zoom, not multitouch.
Working as designed.

There is a bug, as the Droid Incredible is only Dual touch as well but doesn't do the same thing. Just don't call it a multitouch bug but its still a bug.

As you said 3 posts up, the Droid has a different touch panel and has more features. Its not a bug, its a limitation. The panel does as it was advertised to do...pinch gestures.
Yes, the axes swap and the points stick together when on close x or y, but this doesn't stop it from doing its job, pinch gestures work fine with these limitations, therefore, not a bug.
The only advertised feature is pinch to zoom, which is working as designed.
Calling the lack of multitouch support a bug is the as same as calling the lack of face camera a bug... ;-)

But as I said in the same post, The touch panel in the desire is advertised to be able to do the gestures needed (both Pivot and rotate) and to close proximity, the phone is incapable of doing these and exhibits strange behaviours when you do them, thats bugginess to me, at worst its a defect, not a limitation.

Its not working as designed, it was designed to do more, it cant for one reason or another, HTC messed up by putting it in the Nexus one and the Desire, thats why we have touch sensitive screen or Pitch to Zoom in brackets, but I'm talking about what the Digitizer manufacturers say it can do.
In your scenario it would be a phone having a camera and a flash in your phone, but to take a picture with a flash doesn't work, then calling it a video light....
I agree that not having real multitouch support is annoying, but you bought this device knowing this.
If you didn't know, you should probably take the habit to read some reviews before buying something...

I was actually using the ""Impersonal You"
Where is here the problem? The list is so short that not only the Desire is missing but many other devices which also have or not any multitouch bug
The whole thing bugs me, so it must be a bug...
its so sad that desire isn't in the list ...
Calm down, someone will make it work, whether it comes to the Desire officially or not.
The Desire's touch panel has an issue where it gets confused if you cross an axis with two fingers at once.
This means the rotating gesture will not work reliably, because if you cross an axis with two fingers at the same time, the map will rotate in the wrong direction.
Everything else should work and I think the issue is a rather small one, so most likely all we need is the .apk (if it doesn't get released for the Desire anyway).
There are apps out that show you what the touch sensor is seeing, where it will register multiple touched locations, but only two actually do anything at the same time. If you put three fingers on it, it will show all three, but if you try to move, only two will show the sliders for each finger moving.
Also, if you try to use two fingers, one at 2 o'clock and one at 7 o'clock, and rotate them clockwise, when they are at the 12/6 or 9/3 axis, the circles at your fingers switch with each other and it acts up.
I agree how some see it as a bug, but I would have to say it is just a limitation due to what our device was designed with. (A black and white TV can't show color picture, it's a hardware limitation, not a bug)
I wonder if something along the lines of the hack that allows single-touch displays to be able to use dual-touch would work to allow dual-touch to use multi-touch...thereby allowing GM5 to work without issue?
Hello,
My desire has some touch related problems, the screen acts like I toching on the top right of the screen (notification bar area) and then he gets crazy, make me to lose my mind many times....
A new touch screen + intallation cost in my country like 100$, and I dont think its worth for such an old device...
There is any way to disable multi touch or and other method that can help me fix this?
Thanks alot,
Daniel.

Frankly, it s quite a known issue t the Desire has a faulty touchscreen and you should know that by having used the search button with lots of occurences.
First thing first: The HTC Desire has a dual- touch screen type and not multitouch. The means it has been designed mainly to support pinch to zoom actions. Therefore only two fingers can be recognized "fine",on the screen.
Why "fine"? Because it actually takes the real position of the first finger and calculate the virtual position of the second finger. This touchscreen configuration has created an issue that is well known as Axis swapping and stickiness. Search this on the Desire and you should get more information that, I hope, will help you very well

I searched about touch related issues, but this is not the problem Iam talking about...
I cant use the phone in avarage use, I getting crazy from using it every day,
Its hardware related issue...
Up, help please
Assuming you can disable multitouch. Your screen acts like it's always touching the top right side of the screen, then you wont even be able to swipe your finger as that top right screen bug will always make use of the touch functionality.
You determined it's a hardware issue then go replace the screen.
Hello all,
Today I started working on an app to test Windows 8 touch capabilities with my Synaptics touchpad. The app kind of works at the moment, but only with one touch point. I haven't figured out how to get the number of the touch point in the touchpad packet data.
How To:
Download the app (link below) and run the SynapticsToTouch.exe. It should work now, try using your touchpad. You may want to calibrate your touchpad with the Calibrate button. Click it and follow the instructions.
Download v0.3 alpha: https://github.com/downloads/Digiex/SynapticsToTouch/SynapticsToTouch_v0.3_c3902b3a54.zip
Source code: https://github.com/Digiex/SynapticsToTouch/
Issue Tracker: https://github.com/Digiex/SynapticsToTouch/issues/
Please fork and fix any bugs you might find
Bug reports and feature requests should go to the issue tracker You can report in this thread too, but they might get ignored.
Awesome work, I always wanted to try Windows 8's touch interface.
It works nicely, however it has some glitches, like tapping in one section of the panel actually translates in the other side of the screen, taps on the start screen get interpreted as scrolling, etc.
It's kinda difficult to hit small buttons tho
Nice work, would like to see more of this.
Keep it up :good:

I fixed the tapping bug, thanks. v0.2 alpha: https://github.com/downloads/Digiex..._07170ef033b5a3eade530a78d9de395e3350da3a.zip
----
v0.3 alpha adds minimizing to taskbar and saving calibration settings. Also a button to run as admin so touch input works everywhere. Download: https://github.com/downloads/Digiex/SynapticsToTouch/SynapticsToTouch_v0.3_c3902b3a54.zip
This is Great! I have been looking everywhere for something like this. To be honest I don't know why the synaptics touchpad isn't designed like this from the start. Synaptics says it has a suite of gestures. Well that's all well and good but half the time the gestures just get in the way. For instance sometimes I just move my finger from left to right and all of a sudden I find myself going from the desktop to the "Start" menu (the one with the apps).
Just noticed something: Is there anyway you can make a keyboard shortcut override? Because of course as soon as you touch the pad it is interpreted as a mouse/finger down event, yet getting the precise location is difficult. So if there was a way to override the mouse/finger down event just until you are in the right area that would be good I think. At least until the user gets used to where on the touchpad to touch in relation to the display.

This app allows you to touch anywhere on your touchpad and have the cursor move to that location on the screen as if you had a touch screen
