Multitouch

Hey,
I'm having a tought here...
On a dual, if you press on the touchscreen with two fingers (on on each side of the screen) the touchscreen recognizes both and thinks you pressed between the two spots (sorry, might be a little confusing added pic for understanding)
Many pda's cant handle a second press on the touchscreen, so i was wondering: if a dual can handle 2 simultaneous inputs, can multitouch be able to work (like typing 2 letters or use gestures like zooming on an iphone OR, scroll with 2 fingers like the mousepad on a macbook and select things with a single finger)
Is it even possible to get it working in windows mobile?? Or has it nothing to do with the touchscreen and is it just the os your using?

I guess not, because multitouch technology uses infrared (warmth detection).
I'm guessing that the touch dual is using resistive touch technology, which captures your position using x- and y-axis coordinates.
Than puts them together.
When you touch multiple places, the microcontroller makes an average of the two coordinates.
That function is also needed for thumb control, cause your thumb obviously has a bigger contact area than 1 pixel.
When you use your thumb to push a button the chip calculates the center of the pressure, so it will only give one coordinate.
Sorry for my somewhat hard to read (cause i'm not WWE) explanation, but I really think you shouldn't hope for it.
Edit: And the OS isn't made for multitouch usage. Try using two mouses on your windows pc, you won't see two cursors which is somewhat a non-argument ofcourse, but multitouch has to be programmed in the OS.

actually multitouch has nothing to do with the TYPE of touch pad... furthermore, if you're referring to the iPhone - it's capacitive... i.e. it uses the human body's ability to store electricity to sense the point of touch. The touch screens on most phones are resistive in that they press two plates together to create a resistance in the electrical flow.
As far as multitouch itself - that's mainly an OS thing.

You're right here is info about the iPhone's touchscreen: http://www.ipodobserver.com/story/31942
Near-infrared is used in the Microsoft Surface tables http://arstechnica.com/news.ars/pos...w-microsofts-surface-a-qa-with-microsoft.html
More info about (other kinds of) touch types: http://en.wikipedia.org/wiki/Touchscreen
But believe me when I say that resistive touch technology doesn't support multi-touch though.

hi
http://www.flicksoftware.com/research/index_files/Page375.htm
the bad thing is it wasnt realeased yet but theres a video.
i dont think this is like iphones technology but it is multitouch

Hahaha! Okay, i'll shut up then

[REQ]Virtual Hardware G buttons

I was thinking about, as the subject, to an app who allow to map the g-sensor as an hardware button.
In some games, for example, where you can assign an action to a button, would great to incline the diamond and assign the action you need (L,R, Up & Down)
I don't know about how work has to be done, but imagine isn't too easy.

the problem is that the Diamond only has one button for personalize: large press in call botton
but other option is use a sensible area of screen how the squares touch pad in notebooks

It would just be a matter of a background process watching the G-Sensor and sending keystrokes via the keybd_event function to the foreground window/focused control. Good idea, and would be pretty easy, but I'm too busy.

I hardly doubt, that you can play with such controller
Like, stressing phone, and screaming at it, as you cannot progress the game
The most suitable is the semi-transparent on-screen controller, like in NES emulator

But withvirtual pad you can't push "Up+A" (per exemple) because WM dont accept "Dual Touch"
Sorry 4 my English...

I think that the game is playable... just find a GOOD algorithm to balance the sensitivity (not too inclined for a direction) and the directions (up, up-right, right, etc)
This is the usually iphone example
BTW think how many game with the emulators and, why not, at the "never seen touchxperience rom"... sending keystrokes (up, down, left, right) in the today screen, album.... to the ACTIVE WINDOW

Please find the time, I think a lot of people would be most appreciative, you've already done so much for the diamond community, c'mon Koush blag a day off work and sort it out! It would almost give us vuflo!

Ok I have began writing this application like an hour ago.
I will keep you updated as soon as I have something usable. (the program works already, but I have to create some windows so you can configure it)

Awesome, can't wait to try this out, thanks for taking this on.

WoW Great NEWS! but all those g-sens related apps can goes in conflict... make in mind to consider a function that auto-rotate the screen (and also the G-gestures)... two control panels like the "Brins0net ScreenRotator" to exclude the rotation of the screen & G-gestures, and the possibility to add windows in execution would be GREAT
...maybe now i'm asking too much BTW it will be THE ONLY NECESSARY G-app in background, for all diamond users.
(hemm should be considered also a screen lock, but is not too necessary)

I'm still working on about all those things...
Now is cup of coffee time
I will first of all end up the "VueFlo"-side of the app and make a first release, then I'll see for other functions like AutoRotation and the interaction between that and "VueFlo".
Just wait a little, I'm almost done with first release

[CLOSED/G2] Soft Touch Keys are all different!

Anybody else notice that on the soft touch keys, the ones at the bottom of the screen on the g2, the home and the back keys are swapped places from a N1...Just thought I would point that out! Sorry I have a Nexus one and was surprised....but now after checking out all the other phones all of them have different layouts, even the droid x, droid incredible and the droid are all different layouts!!
Take a look for yourself....

It would probably take me quite some time to get used to that from my nexus...i think this is an odd thing to do personally, but it does match the g1 good

Similar positioning to the G1. The keys on the G1 from left to right are [Call] [Home] [Menu] [Back] [End]. I'm not so happy that those are soft keys, and Call and End are no where to be found.

Trust me, doesnt take that long. Change android phones thrice, all with different combinations.
Haha, theres what, 4(square) = 16 possible combinations and I guess manufacturers are out to use them all!
TBH, I much prefer this to Windows Pho 7's three button combination. SOme of those designs look a world of tacky.

Yeah this is current line up of almost all newer android phones. The two softkeys next to the app drawer are best used for call button and you can end call the call directly from notification bar no matter your location on the screen. It takes some getting used to (my current phone, the MTS is just like this in terms of set up) but is just as comfortable after a while.

keys are just like the mytouch also. my search button also pulls up quick response

Just to be pedantic, it's not 4^2, but rather 4!, or 24, combinations of four buttons in four possible spaces.

I stand corrected . Should freshen up my probability and stats!

I do infact miss the G1 Keyboard layout, so far I enjoyed a dedicated button for numbers. So far I havent seen it and many people complained about it, oh well. I cant wait for this phone to come out just to root this.

its super annoying! but after a day or 2 you will get used to it; i have atleast..

it seems a lil out of place but can tell till i get the phone and mess with it.
but couldnt the buttons also be remapped with software then re icon with a skin/screen cover

[Q] see this touch screen behavior? Co-linear touch points cause lost of location

Has anyone used the multi touch app to test their touch screen? It looks like this picture. The program projects a vertical and horizontal line across the screen where your finger is. I've noticed that with two fingers, sometimes one of the finger points "disappear" from the screen when it lines up with the other finger - that is, when the horizontal lines from the two points line up.
This happens sometimes when using two fingers, and all the time when using 3 or 4 fingers and making the horizontal lines of all 4 fingers to line up. Since the program uses pure sensor data, without much manipulation from the OS, I think this means the capacitive grid is actually losing the touch location (not seeing the finger that disappears).
I was wondering if it's only on my unit or if anyone else sees that?
I've tested with my finger far apart and close together when lining up the cross hair lines. The disappearing finger location isn't caused by the fingers being too close. It's definitely disappears when the lines fall on the same "grid" line. It happens on the horizontal as well as vertical grid lines.
Thanks.
Here's the app:

I cannot replicate this behaviour either horizontally or vertically either in your suggested app, or another similar app by jpjoyjp called Multitouch Test. In either case, aligning two or more fingers from either hand on the exact same horizontal or vertical grid line doesn't cause any touch points to stop registering.
For reference, I'm on a 32GB stock Transformer with 3.1 US installed.

Using Yet another MultiTouch tester I can't duplicate that behaviour.
It tracks all ten of my fingers splendidly well and I can't get them close enough to make them confused - well, I get confused though and often lift my fingers from the surface when trying to get close

Works fine here. Btw, the limit seems to be 10 fingers. Had to ask someone to help me with experiment. xD

Wait I think I see what you mean now. When you hold one finger and quickly tap with the second one, it doesn't detect that the second finger is not longer there. The key is to hold first finger in the exact same coordinates.
Hehe or not.. I didn't read your description carefully.

Thanks for trying it everyone. Well, I tried again just now, but couldn't reproduce it. Weird. Don't know...seems ok now.

Screen sensitivity issue - does not detect touches at a specific location

I guess I'm just unlucky.
A certain part of my screen does not register touches anymore. When I open up the keyboard and slide across the top row of alphabets, the area around the 'i' alphabet doesn't register the touch - the screen will register my touch on the alphabets 't' 'y' 'u' 'o' 'p' but not the 'i'. Same with the alphabet 'n'. This makes typing really, really hard - I have to retype the 'i' and 'n' at least 3 times to get the right alphabet, normally it will come up as a combination of the letters at the side.
Sometimes when I do up/down swiping gestures around that area, the screen will not register the touch too.
And my warranty expired last month. Great phone yeah. (But I've unlocked the bootloader ages ago so oh well)

I had the same problem, but I sent it for repairs, but 1 month later, the same **** started happening. Turns out if you use the slider too much, the screen just sort of stops working according to a guy at the shop I sent for repairs too. That or he was doing a **** job.

WHILE THERE ARE BETTER SCREENS (AMOLED, IPS, CRT... etc)?

Had the same problem, just replace the digitizer and it'll be as good as new. :good:

Use a t9 keyboard! It's a workaround, yeah, but it's worth it.

Use the service menu to test the affected area of touchscreen

Happened to mine after 1 year, had the digitizer replaced.
