Is multitouch broken on the Nexus One? Sort of… - HD2 General

This video and the reply from Google makes me think that this could be related to the screen and touch issues that we have been seeing with the HD2:
http://androidandme.com/2010/03/news/is-multitouch-broken-on-the-nexus-one/
Looks like it's down to the quality of the sensor that HTC have used on their devices and I doubt that they did anything different with the HD2. The larger screen may have just made the problem more apparent.
EDIT: Added links to the two main threads on the HD2 Screen problems below.

Yup looks messed upto me on the Nexus, the Driod has a better screen or something according to Google (well worded differently ;p) maybe thats why theres confusion about the HD2 geting a WP7S upgrade as it requires a 4 point mutlitouch screen or something.

4point multitouch screen is a software support not hardware

This looks like driver issue. Bad code. No faulty hardware as it is in case of HD2. I bet it would affect all Nexuses .. unlike on HD2 (for example mine is perfect).
Multitouch sensor can detect if any point on the screen is touched or not (with some resolution, rather poor actually).
The driver must find 'islands' of touched points of some minimal size, then compute center of that 'island' and that is the 'touched point'. Problem is there is a lot of noise coming from all the sensor, and lot of averaging and smoothing comes into play. On droid you can see how the points merge a bit earlier then you would expect, that is because of this. Also it is understandable that the sensor can't distinguish which point was which after the merge.
On Nexus there is clearly some rather more simple implementation of these algorithms, or they contain serious bug. Good think is that I believe it is totally fixable on the software side.

but does the hd2 has proper drivers ,and another question (does the shaking screen when zooming is hardware isse )

Im not sure its real multitouch on the HD2 rather pinch to zoom, seems to be implemented the same way on the Nexus

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...

Out of curiosity where do we find this skin? all I can find is that youtube video. At the moment I'm getting a little bored with my current ROM and right now am looking for a new replacement look on my vogue.

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.

specially for hd which has almost no hardware buttons multitouch would be a nice feature videogame-wise... like shooting while running or steering while accelerating...
btw check out the blackstone rom development forum a custom rom with winmo6.5 beta has been released already. Just for testing purposes only though.

Imagine a perfect device...

What kind of device would it take to make you leave touch HD and switch to something new?
I've been looking at some of the latest generation devices popping out (from various manufacturers) and I have to say I have not been not one bit tempted to make the switch.
So, for some future imaginary HTC device, here's what I'd like to see addressed:
Hardware related:
1. Illuminated hardware touch sensitive keys. I really hate this isn't present on Touch HD. A tinly LED would solve this and make the device much more usable in the dark.
2. More hardware keys. Perhaps a camera button, or simply few "blank" buttons that users can customize. A scroll wheel would be awesome.
3. A better visual indicator of received / missed calls and messages. That tiny LED on power button is hardly noticeable. They should've placed it on front side.
4. More easier way to soft-reset and swap memory cards. Perhaps dual memory card slots.
5. Make the device slightly more responsive, either by increasing memory / processor speed, or optimizing the bundled software. If ROM chefs can do it, I guess HTC can too.
6. FLASHLIGHT LED (This should've been the first on the list )
7. Add multi-touch.
8. Video output would be nice.
9. Make an accessory that would serve as a small portable and detachable Bluetooth keyboard. I can't figure out why HTC doesn't offer this. Is it so hard to rip out the keyboard from say new Touch Pro 2 and put a battery and Bluetooth chip inside that would work as a HID interface device?
SOFTWARE RELATED
1. Proper drivers that support hardware video acceleration.
2. Complete overhaul of Touch Flo 3D. Make it skinnable, make it highly user-configurable, integrate it even deeper over ugly WinMo.
3. Fix the annoying bugs.
4. Add default Divx and Xvid support. For a device with word "HD" in it's name, and such a big screen, this really should've been done long ago.
I'll leave other ideas to you
I like where you are going with this. However we all know that the "perfect" device will never be made due to the fact that people will then have no reason to purchase anything new unless hardware tech increases.
They aren't going to bundle everything you have said in there due to the compromise they would have to make between power/battery life/useability.
However I'd almost like to see a cut down version of this...iPhone like I suppose. Only offer 10 features or so (good overlay of SMS, Email, web browsing layers) but do it almost seamlessly without the need for using WinMo standards (such as SMS etc..). Get those right and provide a sleek, slim, portable, and cheaper device.
The one thing I hate is the fact that I have a front camera on the touch hd but hardly any software to take advantage of it in terms of video calling....renders it useless.

I agree with you in some aspects. Yes their will never be a perfect phone as everyone has different opinions on what the perfect phone is. So what may be perfect to you, may be no where near perfect for me etc. Thats why there will always be a wide variety of phones.
I disagree with you on manufacturers bundling everything into phones as that is what is currently being implemented by all manufacturers. Phones nowadays aren't just a phone they have cameras, radios, mp3 players, navigational apps like tomtom, tv tuners, personal organisers etc. Why have one of each when you can have one in all. This is what the customer wants and the manufacturers are realising this and are already producing devices with this already built in. With time the quality of these devices will improve.....but there will always be room for improvement. This is why we will never be happy IMO. For example. If you go out and buy a 50 inch plasma tv. Next year a better model will e available and you will want it instead etc etc etc.
Thats my 2 cents anyhow!!
Happy to say that people share the same thought. at least it is one step closer to be perfect.

I'm not sure a "perfect" device will never be made. There were some in the past that would pretty much fit into "perfect" category, based on their market position and "features vs. price vs. usability".
Also, I do not advocate putting everything into every device, but as you know, Touch HD is sitting pretty much at the top of the food chain when it comes to Windows Mobile devices. So, it's logical that it's feature pack will be bigger then the devices placed lower. I don't even want to throw in the average mobile phones in here.
My ideas are mostly very easy to implement / improve. For example, lets take a look at the Touch HD camera. They packed inside a 5 megapixel camera that takes rather ****ty photos even in perfect conditions, and they left out a LED flashlight. Wouldn't you rather have a LED flash and 3 megapixel camera that takes decent photos? Not to mention that the flashlight can also be used as a torch light in everyday situations.
Battery life on Touch HD is actually best out of all 2008. touch screen devices. Believe it or not, but you'll actually squeeze 30 minutes more battery out of Touch HD then out of famous iPhone, and the rest of the touchscreen gang isn't even close! I would gladly give up 10-15% battery life for an illuminated hardware keys and a flashlight and pay equally bigger end price.

Agree with you there mate, though I don't think a compromise on camera i.e. 3 MP with flashlight is the way forward. Look at Samsung for instance. They are able to provide 8MP cameras with autofocus and flashlight. Why can't HTC follow suit? Instead they keep throwing out 3.2MP with flashlight. I heard there next release is still only 5MP. Why not try and leap infront of their competitors? Its this kind of thing which irritates me

Ah, well, the reason for Samsung offering some pretty damn good phone cameras is simple: they already have a strong photo / video department within their company. Heck, they even have an SLR photo cameras, not to mention quite decent compact cameras.
So, with that technology already being developed and implemented within the house, it's much more simpler for them to throw out devices with 8 megapixel cameras and autofocus and xeon flashlight.
HTC is (s)lacking in this area.

Yes to some extent, but I think thats to easy an excuse personally. The technology is out there and easily copied between manufactuers and competitors. All you would need to do is go out and buy some camera, take it apart and learn how it worked. How long have cameras been around, and HTC is japanese. Aren't they supposed to be the best at compact electronics??
2 Years ago when I got my Prophet I thought about the same topic.
At that time I wanted a bigger screen with a higher resolution, a 3,5mm audio jack and a faster processor. When the HD came I thought it would be the perfect device for me but now I want other things.
The most annoying thing of the HD is the lack of Hardware keys and D-PAD.
I used them all the time with my Prophet and many programs need them or are much more usable with D-PAD and real hardware buttons. I've always asked myself why HTC gave the HD only 2 Hardware Keys. It may have the touch keys but they aren't usable when the screen is off and you press them sometimes by mistake and they aren't really usable at night.
They could just take a look at some old devices and see what they did better with them. For example the reset key. On my Prophet it was easy accessible without the need to remove the cover. The same with the SD card.
One good thing is that you can change the SIM while the device is running. It isn't easy because there is a pin that should prevent it but with some force you can take out the SIM without taking out the battery. So why can't they make the SIM easy changeable if possible even without the need of removing the cover.
The camera is bad but I haven't seen a really good camera from HTC yet. The only thing it can better than most other camera phones is taking videos because it doesn't use 3gp but that is everything good there is to the camera of the HD. And they could make the camera much better only by putting in a flash because without much light the camera of the HD isn't usable.

HTC aren't Japanese as far as I'm aware. They're Taiwanese, and generally they're best @ mass producing stuff and not exactly classy innovation (just look at ASUS, Gigabyte and all the other Taiwanese PC co's....).
Anyways, my wishlist for a "perfect" device with (hopefully!) near-future avaliability (some of these may have been mentioned already):
Hardware:
1. MultiTouch. Apparently with some new software even resistive screens can be as nice as responsive as capacitive ones.
2. 3.7" WVGA screen. Yeah I know smaller than the current 3.8" on the HD, but a slightly smaller screen = better handling when only using one hand, v. important for a mobile device imho. And @ that size, it's still possible to read (just) webpages without zooming in massive amounts (unlike the X1 / Diamond2)
3. Dual-LED Flash (at least!) w/ Auto-Flash. If SE can get Auto-Flash working on the X1, so can HTC!
4. SonyEriccson W950-style backlit buttons instead of the capacitive ones they have right now. It's annoying since I sometimes accidentally press those without meaning to.
5. Lanyard hook / hole. WTH they didn't include it before, I dunno.
6. (Optional) Slide-out landscape keyboard w/ dpad (kinda like the N97, but no silly angled slide)... always nice to have a proper keyboard when typing long emails
7. 1Ghz Snapdragon or some other sort of beefy processor so we can enjoy games and other stuff @ WVGA res without slowing down!
8. At least 512mb RAM. I want to be able to do TRUE multitasking and not have to shutdown apps just because Opera is starting up. And I wanna stop getting those annoying "out of memory errors" from NFS:U!
Software:
1. More stable OS. I don't wanna have to soft-reset the device every couple of days! If my previous Symbian-based UIQ3 SE W960 could work for weeks on end without having to reset it, WinMo should be able to do the same.
+ What Rozenthal said
So many people share the thoughts on the obvious defects in HD.
Was wondering whether I should return it. But which one else could be the good substituion?
In another word, HD is the perfect device til now?

If you're going for Windows Mobile, I don't think you'll find a better device available at this moment. I would not go as far to say that it's "perfect" - as any high-tech device, it has it's downsides and annoying moments, but it is the best you can get.
Also, biggest change for me since getting my Touch HD was flashing a custom made ROM. That felt pretty much like getting a new device.

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?

Does the HD2 have true multitouch?

One thing that worries me about the HD2 is the touchscreen sensors. If it's just the same ones as the Nexus One, Synaptics CP2000 with faulty multitouch, I might have to reconsider my options.
It does have true multitouch. Youtube it there are a bunch of videos out there.
After seeing YT videos, it looks like the same wonky multitouch in Nexus One. I'm disappointed
What is it you find "wonky" about it
No it's not. Some of the first run HD2s had some bad sensors, but we don't have any trouble crossing streams or whatever you N1 kids call it nowadays.
Like in this video
http://www.youtube.com/watch?v=tTqh6u2OUFU
Sometimes it jumps all over the place.
And in here
http://www.youtube.com/watch?v=Hgrsq2-Vy7Q&feature=channel
It sometimes sticks when you're near the same axis.
The sticking is an auto-align in the driver.
Is there a way to turn that off? Does it support more than 2 fingers?
The limitation is currently the way the HTC code sends the data to other applications. It may be possible to get more points with a lower level hook, though I haven't yet gone that far as I want to investigate what can be done so far

Back in Nov, guess they got lazy
Not sure about turning it off.
HD2 has multitouch, but can only recognize 2 touch points.
(WP7S min requirement is 4 touch points)
As you can see here:
http://www.youtube.com/watch?v=qzhUzq6bTPg&feature=player_embedded
The N1 multi-touch issue is very pronounced and extremely different.
I just grabbed both Scilor and |3v5y apps for multitouch.
In the Scilor app (with two circles) you can see a clear snap when you are on the same x or y axis, but again this is driver behavior. Nothing unusual besides that.
In the |3v5y app, the x axis doesn't show any snapping, but crossing on the y axis (possibly a coding error?) swaps the 'paint stream' under the fingers, but still keeps with original positions.
This is similar to the droid on the youtube video above, where the blue and red dot might flip, but it doesn't lose track of what is being touched. Thus, not the same problem as the N1. Not the same sensor. Hurray, hurrah.

Not true. HD2 2-point multitouch is a driver (soft) limitation, if you read what I just quoted.
On that note does anyone know what sensor HD2 uses?

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

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.
the touch panel is capable of it.... just bad drivers.... htc is known for f*cking good hardware with ****ty drivers

i see, hope there will be a fix in the future, because HD2 is one of the most capable smartphone ever... kind of unfortunate when the software cant utilize its full potential!
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 :/

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
