Conclusion: There IS Accelerometer, only they call it G-Sensor, thanks for all the feedback!
Dear fellows,
I was unpleasantly surprised to find that Touch HD does NOT have an accelerometer, rather only a G-Sensor. (Some more detail: Accelerometer is supposed to sense "acceleration," typically in all three dimensions x,y and z. With software support, orientation sensing can be done as one usage. G-Sensor is an inferior sensor that only gives information about orientation, no velocity/acceleration sensing). Although it can be argued that most typical uses are covered by G-Sensor (like screen orientation), but the key word is "most" Accelerometer is definitively more useful in gaming, and potentially other applications. I searched several other threads and found many people equating G-Sensor with accelerometer. I hope this thread can add some clarification.
To me it looks like another effort by HTC to cut on a few bucks. Anyway I still consider it as a minor setback to me in my overall enthusiasm for Touh HD Just missing one good argument to an iphone user (no iphone debate wars intended here )
Best regards.

another victim fallen to the marketing gimmick of a "buzz word", accelerometer, despite its name doesn't necessary mean it must detect acceleration, iphone's accelerometer doesn't do that. none on the market do that. if in the future there's a similar device that can detect acceleration, then it may fall into the "accelerometer" category, or market people will create a new buzz word to highlight its features.
but g senor, motion sensor and accelerometer are the same thing as the market/technology stands now. i made the same mistake and was corrected as well:

Thanks. Well if this is indeed true (that iphone and others also only have a G-Sensor) I dont think I can call it marketing gimik. It is plain dishonesty. An accelerometer is a well understood term, misusing it is... well!
But have you checked that for iphone. I will check that tomorrow with one colleague who has one. Wikipedia gives different info here, I quote:
"For example, Apple uses an LIS302DL accelerometer in the iPhone, iPod Touch and the 4th generation iPod Nano allowing the device to know when it is tilted on its side."
LIS302DL is indeed a full blown accelerometer, not just g-sensor! So lets recheck and compare our notes. Thanks for the feedback!
I think the proof is in the fact that you cant do anything with the Iphone's "accelerometer" that you cant also do with the HTC "g-sensor" If there was a fundamental difference in their capability it would have been exploited by now.

Wake up ppl, all these applications discussed above are using GPS signal in conjunction with G-sensing. So this discussion is not relevant to this topic!!
Doing some more digging here and the source code shows my first post is accurate. There IS a FULL LIS302DL accelerometer in iphone, and we are stuck with G-Sensor of HD.... means we cant "shake things around" literally.

No they don't use GPS for Accel, it is impossible to measure short time Accell with GPS accuracy.
G-Sensor is just another Name for Accelerometer. Both Sensors (IPhone and HD) have nearly the same accuracy in there API, so if you look to the source of the IPhone you should also look at the Sensor-API of the HTC's ;_)).
So HD/Diamond/Raphael has not only a "Tilt-On/Off"-Sensor as you try to explain, it is indeed a "full"-Accelerometer. You could just install one of the mentioned Programs to prove that the indeed are measuring acceleration .
And if you are really interested you should look at: http://www.koushikdutta.com/2008/07/using-htc-touch-diamond-sensor-sdk-from.html
to learn how to program the Accelerometer.
BTW Gyroscope-Sensors are brand new, and no phone to date has one , the should be cheaper and more accurate as the today build in Sensors.
Rivendel is absolutely right. The applications wouldn't work without a proper accelerometer.
Originally, micromachined accelerometers would have been very expensive, but now there is so much demand for them that they can be bought for about a dollar in large quantity.

OK, yes I guess you are right too; Pocket GForce register lots of Gs just moving the device sideways without tilting it much, so some measurement of acceleration is there. Then may be, HTC ppl should upgrade and call it accelerometer!

Well G-Sensor does allude to acceleration if you take name to mean a sensor which measures G-Force....
G sensors and accelerometers are exactly the same thing.the former is more of layman and commercial term while the later is the more appropriate technical term.what it does is measure acceleration as its name suggest.this device can be position in any axis(x,y,z).a complete system should consist of 3 accelerometers in exact tangent to each other in those 3 axis so that it can sense vertical,horizontal and lateral accelerations.since acceleration is measured in "meters/seconds squared"the value of acceleration when integrated once will give u distance and when integrated twice will give u time.this is the basis of any stand alone navigation or guidance systems but it must be coupled with a 3 axis gyroscopic system to give attitude information.in the phone,the accelerometers measure the gravity force which has an acceleration of approx 10 m/s squared.the resultant output will determine the phone's orientation
it has an acceltomater, with diamonds vr hologram, if you lay it on a flat surface, and push it artound, it wil stil move

Some Nokia phones have had Gyroscope-Sensor for over year by now, it rotates the map in the navigating software real time when u spin around, its very handy when navigating by walking.
I think that's a digital compass in the Nokia phones. A lot of the recent ones don't have the compass though (N95, etc.)

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:

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.
Hi to all of those Leo owners.
Is it true that there is no stylus with the Leo?
I have large fingers and the built in stylus (eg like that of the Diamond2) is a must.
And there is no second camera for video calling?
I also use this feature and it is not on this phone.
I know many are saying the Leo is a great phone but without these 2 features it seems sadly lacking.
It would be nice if it also came with an 8 megapixel or more camera.
What do you guys think?
Aussie
just shut up, and don`t buy it, and never ever visit this part of xda ok?
Hey,
jep thats correct ... no stylus and no second video cam for conference calls.
but there was a link for an stylus on the web, that can used with the capacitive screen.
regards
I don't care about video calls and I WANT device with capacitive (and large) screen. So HD2 is simply exactly what I want. If it is not for you, I agree with previous poster, even if I don't approve on his style.

There is no use for a stylus with a capacitive screen. The only thing that you are really giving up is the ability to use notepad, which I use quite a bit.

Thanks for the feedback
Hi again
Thanks for the constructive feedback. The other feedback just shows how anal some of you are.
Some sellers in my country sell the Leo with a stylus. But the specs and reviews say there is none. Scouring the net shows a few expressing their disappointment with the lack of stylus which helps with apps that require precision tapping or touching (eg Spreadsheets, games etc) or for those who just have large fingers.
Perhaps those who have told me to just "shut up" and not to "visit xda" should follow their own advice if they have nothing constructive to add.
Dont forget to burp your Leo.
Cheers

I don't have an iPhone so it's hard to compare. I do have an iPod which I have used an awesome 3 times. Compared to what I remember, it's control is a bit better. The Leo screen is very sensitive. Looking at it almost makes stuff happen There's a fix that lowers the sensitivity around here though, but I have not tried that out yet. As it is, without fix, typing accurately is a real pain. I would have much prefered if it had came with a capacitive stylus, as HTC does make those...

Someone should really make a thought control program for the HD2 then there would be no need for fingers or styluses at all
The capacative styluses on ebay are very competant especially for hand written notes or navigating around windows explorers. I wouldnt advise trimming them down though as I decided to do one night to see if a more precise point could be made, I guess the styluses need a certain surface area making contact with the screen which is probably why they are made like that HAHA.
Ohh well at least I have 1 left which works well on my ipod touch so it should be fine with my HD2.. IF IT EVER ARRIVES!!

that control program is allready made, you can enable pinch to zoom in every application, so if you have problems tapping on some small button, you can zoom in... it is pretty usefull, but i never used it for example in explorer... i don`t have any problems clicking anywhere
The lack of stylus is a bit of a problem (Especially considering the fact I use many spreadsheet files).
The more problematic thing is that HTC has developed a stylus for capacitive screens,
but do not include it with the device that should be their Flag-Ship device.
The lack of stylus results the keyboard size to be huge eating up a lot of screen space,
instead of including a stylus and letting the user choose wheter to use it or not,
and allowing the user to set the keyboard size to his pereferenced size.
Now - there are several "capacitive screen" styli out there that might work just fine
so there is a solution - but - I would have expected that HTC would supply a stylus,
especially when thay have already designed one.

It would be interesting to see how the future goes with the competition between Capacitive and Resistive screens. Software developers either code them all under one roof (I'm not a developer, so I'm not sure how hard!!!) or have different versions (meaning more works and costly). Because the new WM 6.5.x are very Capacitive screen friendly. M$ did a good job on the cosmetics and it's functions!

FWIW anyone that is willing to part with £500 for a phone or anything else should be thoroughly researching every aspect of what they are buying including the company that is making it. If anything, researching the company is more important than all else as it gives insight as to build quality, customer support, future updates and fixes for what you are buying.
Even though HTC has many failings with regards to drivers and customer support I am still more than excited to get the HD2 as soon as I can, not just because the Hardware spec is the best available in todays phones but mainly because I know the dedicated members of xda-developers (which I am proud to be a part of) wont rest until the HTC HD2's full potential is unocked for the benefit of everyone.

I believe the future of Mobile Phones is capacitive screens whether people like it or not. All the major manufactures will start phasing out resistive screens in favour of capacitive technology due to the faster and more responsive feel of it. Styluses will also be phased out as Windows Mobile 7 and other 3rd party apps will have larger and more finger friendly buttons and menus.
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?
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 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 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".

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.
