Touchscreen accuracy - Touch Pro, Fuze General

Hello.
I want to ask,if is possible to decrease touchscreen accuracy to be sensible as QVGA?
Explanation:
I think,that the digitizer wants to recognize exactly the current pixel from small VGA screen. The problem is,that when you touch the pixel,it is necessary to release the display at the same pixel for confirming your action. If you move to neighbour pixel,the action isn't confirmed often. Unfortunately the screen is very small and this is very difficult to perform with the fingers. On old QVGA PPC's is not so sensitive,so I will be happy,if we can be able this pixel recognize as a 2x2pix.area. The main problem is when you try to tap small icon,where on the QVGA 2.8" screen you do it without problem,VGA 2.8" makes it quite impossible.
Any ideas?

display sensitivity

Is there in WM6 a registry entry to increase the sensitivity of the touchscreen, because the touch function works quite poor.
thx
have you tried to clean or change the protector of that screen. I had the same problem before, and after remove the protector and clean very well the screen, that doesn't repete.
Just don't expect the same sensitivity that you see on a lot of the newer phones. They use capacitive touch screens where as the wizard is a resistive touch screen.

Software idea for increasing touch usability

Something along these lines may have already been created, but I havent been able to find it. Shell software, and touch flo is all very good for using our phones without a stylus, but we all know that at some point we are going to have to use a piece of wm software, and out the stylus comes.
What I am proposing is a virtual mouse cursor. I came across Innovisoft Virtuamouse, which is controled by the d-pad, but why not have a cursor about 50*50 pixels, which can be moved by finger.
In my paint mockup picture, the red circle would be where you touch to drag the cursor, and the tip is the active point where the stylus would tap. It would be moved by dragging, and a stylus tap would be signified by removing and replacing the finger within 200ms, like a laptop touchpad.
This cursor would probably be turned on and off by a hardware button.
Unfortunately I am not a developer, so this would have to be a project for someone else, but I'm sure people would be willing to contribute.
Since the Diamond having multi-touch seems to be comfirmed (link below), I would bet that one of the first things we see from deevelopers is just this idea. Using the touch-sensitive part of the area around the action button as a trackpad and clicking with a button press.

Seems like a good idea, but I do have to question this a bit. You want to use a touch controlled mouse to tap a button? It seems like a bit more work to do. Also, your picture is a smartphone....
The idea is to use the mouse to press the odd, fiddely button, not for constant use.
As for that being a smartphone screen, that was an overlook on my part - I just grabbed the first screen capture off google images.
I think it would be useful for web browsing.

Touch Screen Problem

I just bought the Fuze. The screen looks awesome. However I am having a problem where the touch screen is very unresponsive. I find myself having to tap the screen two or three times to get it to react. For example, I have to tap the Windows icon a few times before the menu opens. I also find that pressing harder on the screen with my finger or stylus makes it react a bit better as well. I shouldn't have to press that hard however. I never had an issue like that on my Kaiser.
Was wondering if anyone else has this problem. Could it be an unoptimized OS or video driver? Any way to adjust the sensitivity of the touch screen? Basically, I want to know if this might be an OS issue vs. a hardware issue.
I hate to return such a nice phone because of how unrepsonsive it is.
BTW, I am using ROMeOS v1.4.
Thanks for any inputs.
Its probably not defective in anyway. The fuze screen is a resistive screen, not a capacitive screen (the iPhone), so you do need to press a little harder. You can install the advanced config app and/or the TF3D customizer app to change the screen sensitivity. I have it on my fuze and it does make quite a difference.
FYI you need .NET compact framework 3.5 in order for advanced config to work

Thanks for the reply. What setting did you use?
I just use the TF3D config with performance setting #4, which is the screen sensitivity one, I believe. I find that to be the best setting. The other thing you might wanna try, even though it may seem obvious, is realign the screen. that could cause some problems.
Screen Not Responsive
my screen has become unresponsive over 75% of the time. same w/stylus or finger. already adjusted sensitvity through Advanced config tool, and Diamond tweak. try to re-align screen, and most of the time, screen does not even recognize the taps. This happened on previous one I exchanged. HELP ! !
Do you have a screen protector on your device?
I noticed that my Touch Pro was very unresponsive until I got rid of the stock screen protector and used it bare-screen
Try the second cab in this post
http://forum.xda-developers.com/showthread.php?t=469865
It drastically increases sensitivity for our pleasure--i felt that it does a better job than TF3D and Advanced Config. There may be an issue with your ROM--my old Tilt would lag on me dependent on the ROM even when the programs installed were identical. Currently using NATF's.
Screen Not Responsive - fixed
Wow ! !, I never would have thought it was the screen protector. I took it off, and it works great. thank you to TehPenguin. maybe it needs to be changed more often, or use a different brand.
That, was my second guess...but seriously, try the cab...
If you're using a snap=on case that can also cause the screen to stop responding. I was using a very cool looking red snap-on case I got from ebay. I got home from work today pulled out my phone to do something and it was completely unresponsive. I finally took off the case and it worked fine.

Multitouch on a single touch screen.

This guy made it on a nokia...
http://30dbs.blogspot.com/2009/03/experimental-multi-touch-on-nokia-5800.html
i dont think this is real multitouch- just seems to remember the first pressed location and notices when pressure is gone
its not really multitouch.
i worked on a simular project (not a game, just tried to do something like virtual multitouch)
and its just like that.
example:
you press on the left and on the right side of our screen, wm thinks you were pressing just in the middle of both sides.
like this (X is your finger, O is the position where windows mobil thinks where your finger really is)
X-----O-----X
or
X----------
-----O-----
----------X
so i think this guy just made "invisible buttons" which you click when you press und 2 of his buttons at the same time.
of course this is just speculation because i cant test it, but that would be the easiest way.
Yep I think it's how it works... But it's not a dumb idea at all, and could be used in the dev of apps

I agree with you.
This "trick" can simulate a multitouch but only with single clicks. I'm afraid that you can't simulate gestures such as the "iPhone-like" zoom.

Yeah, I realize it isn’t "real" multitouch to, but I also think this could be useful for a lot of cool apps on WM.
I was making some experiments and I noticed that it is really hard, if not impossible, to make it work with 3 simultaneous pressures.
Like freaksey said, pressing in 2 different points of the screen will make the OS think we are pressing in a point in the middle. But introducing a third point will not be detected if the point is in the same line.
Here is what I mean:
X----X----X (3 points)
X---------X (2 points)
X----O----X (What the OS thinks in both situations)
So I'm afraid that we can't make applications like "piano".

Indeed, not like a piano, but for tiny games (like the nokia guy made) it could be fun

I reckon u could simulate multitouch for zooming. And here is how i suggest to do it (im not a programmer, so someone come use it (Y)!)
When using a transitional touch screen, a user either presses a button and then releases it (taps it), and then taps another, or drags a stylus across the screen. When a user taps, there is a space of a few milliseconds of no input between the taps, so is recognisable.
When a user drags a stylus, the change in location is continuous (i.e. the point of contact moves to an adjacent sensor), so is recognisable.
If a user were to touch 2 points, the point of contact would appear to move straight to another point (not adjacent) immediately. This would then be recognisable as 2 points of contact, rather than just 2 taps.
This would allow 2 fingered gestures, even if the system wouldn't know the exact location of the 2 points of contact.
try this... here can you see where your phone thinks your finger is.
(to go into "singlepoint mode" draw at least 1 point on your screen and then you can change into it)
just copy to phone and run it
I am not a hardware engineer by any stretch of the imagination, but I feel this is more of a software limitation than anything else.
The fact that windows mobile can take two points of pressure and use the middle of the area as the true touch point, tells me that the hardware is understanding both touch points.
I believe the issue lies in Windows for not understanding two inputs at the same time. This is the same case with Windows PC's, as multi-touch is not possible on Vista or XP, but instead is being developed specifically for Window 7. Same thing with Windows Mobile, multi-touch is being developed (on a software level) only with WM 7.
Correct me if I am wrong, but the Android powered HTC phone has similar touch screen hardware as most current HTC devices, but a developer was able to (with some changes to the OS) allow for true multi touch recognition.
You are right, viridescent_zeal.
But I already tried what you are saying and if you press 2 point "at the same time" the hardware will immediatly get the point in the middle. It will not move immediatly but it will immediatly result as the point in the middle.
I'm afraid that it is an hardware limitation. If you want to realize the behaviour you are talking about, you have to press the two points with a little delay. This will cause the immediate movement and you can make a software believe you have touched two points in the screen.

It isn't a software limitation. This is just how resistive digitisers work.
here's two artciles from the last 24 hours showing multitouch in action:
http://www.fuzemobility.com/multitouch-exists-now-without-new-hardware-or-software/
http://www.fuzemobility.com/multitouch-in-action/
it can be implemented for games in a butchered form...it's not real multitouch but virtual key presses can work for games.
Very true. Still, be able to do that is better than nothing- if done right it could simulate multi-touch gestures providing we put 1 finger down first!

MultiTouch exists right now - no new hardware needed (with video)

Take a look: http://www.fuzemobility.com/multitouch-exists-now-without-new-hardware-or-software/
On a Windows device pressing two points leads to a key press of a point in between those points. That means for games you can create a virtual key in between the two points that is mapped as pressing both buttons. It works right now on your device. Just press down with a sharp object (like two styluses) on two points and the point in the middle will be 'pressed'. It's not very easy to do consistently but it does work.
This means games can be created for multitouch as long as virtual keys are mapped for dual key presses.
Not really multitouch though...you couldn't draw two lines at once or use it to drag-rotate/resize an object. Still, might be useful for games in certain circumstances if you could work out a way to do it reliably...

you can get Guitar Hero to play just like they did on the Nokia... it can be done but I agree that you can't use this to 'pinch' items for example...
thats not really multi touch with most any touch screen display that isnt multitouch capable if you touch the screen at 2 different points the screen will think your touching the middle of the 2 points you actually touched same thing happens on my hp pavillion tx2000 laptop and that doesnt have a multitouch screen
Where can I download the game he is playing? Or any form of ddr/guitar hero/etc?
