New Firmware with QT4.6
 
The new Firmware will be with QT4.6 which means multi touch and now days touch screen resistive have the ability to be multi touch

Slap this in the face of all the idiots asking blindly for the next N900 to be capacitive!

Very very nice! Resistive rules.

Re: New Firmware with QT4.6
 
The demo is awesome - multi-touch and stylus input at the same time.
(The demonstrator even used a brush on the screen!)

This is exactly what was needed.

QT 4.6 for Maemo 5

QT 4.6 is scheduled for official release in PR 1.2.

Re: New Firmware with QT4.6
 
I take it there is a hardware element to this rather than just the firmware? A hardware element that isn't yet implemented on the nokia phones

Re: New Firmware with QT4.6
 
There can be no multi touch on the N900. It's possible to simulate it with clever software that can recognise gestures - but it's not true multi touch like a capacitive screen.

Re: New Firmware with QT4.6
 
Very interesting.

If Multi-Touch is something that can come to the N900 then it looks much better for the likelihood of Meego.

depu 2010-02-17 09:49

Re: New Firmware with QT4.6
 
The OP comment is misleading. QT 4.6 has support for multi touch. However, since the N900 is lacking the hardware to implement multi touch the firmware having QT 4.6 is not going to make the N900 register multitouch events.

So,
QT 4.6 in new firmware------------> yes
Multitouch on N900 with new firmware--------> no

TFT LCD panel is a Sony ACX565AKM with Texas Instrument TSC2005 as touch screen controller and it supports Multi Touch technology. Kindly clarify if it cannot support please

The difference between Iphone 3GS and Nokia N900 is the screens one used capacitative and other uses resistive and Same CPU, Same GPU.

Looking for more information for it and will be back with more details

Stantum multi touch just barely made it into a production screen like a month or so ago so how can N900 have stantums tech?

Stantum's technology is a software-based refinement to resistive touchscreens that allows for accuracy beyond the pixel density of the display, a complete lack of touchscreen "jitters" and some fairly incredible input methods. So it Nokia N900 has the hardware (Which I think it has) then a software update can load Stantum into is as well.


Correct me if I am wrong

There are working implementations of multi-touch by Gary Birkett
http://liqbase.net/liqbase_classic.html (see title multitouch simulation)

works with n800 etc but I'd say that the demo video requires more from resistive touchscreen that any maemo device has packed in.

Neither of those supports multi touch. Where did you get that particular piece of info?
The TSC2005 is a *resistive* 4wire configuration controller.

PS: the touchscreen itself is a KIA-V12F KIAV12H according to this LCD replacement website . However, there is not a single hit on Google for this or similar article numbers.

Hardware Specs is what i refer to. From the looks of the name KIA-V12F KIAV12H it might be a internal part reference number, but i am not sure of that.

Sorry again, but we seem to end up on opposite sides :)
Stantum's technology sounds more like a hardware based touchscreen implementation since Stantum manufactures multi-touch touch screens.
From their site
Quote:

Here is how Stantum-type touch-panels are manufactured:

1. Two thin and transparent (glass or plastic) overlays are covered with conductive material
2. The material is patterned in rows on one side and columns on the other, transforming the layers into a matrix of conductive tracks.
3. The two layers are assembled superposed, the conductive sides facing each other and separated by a spacing material (transparent dots, air, etc.).

I'm not sure - Stantum's original technology was a new design for resistive touch screens which allowed them to handle multi-touch. According to the comments on this article which shows a demo of the current Stantum multi-touch, there's still a hardware component to their technology. This would rule it out for the N900.

And he is still correct. The video shows it working on a new type of resistive screen, one that has been been designed by Stantum and is not used in any production device.

To implement that on the N900 you would need to upgrade the touch screen lcd, the contoller chip, the device kernels and god knows what else. Not exactly possible as a firmware upgrade :)

Those Stantum resistive touchscreens are different from other resistive touchscreens. The fact that they support multitouch doesn't mean that every resistive screen supports it and chances are the N900 has just a regular resistive screen.

He says at the end of the video

"..you cannot adapt our technology to existing phones.."

2:20 of the video. This after he says that they're working with major manufacturers and the screens are ready.I took to mean that existing screens cannot make use of their tech.

Re: New Firmware with QT4.6
 
I don't think the current implementations using 4 wires can ever be converted to multitouch. Since we are only getting the resistance between X, Y I can't imagine a possibility to actually identify multiple inputs without a major hardware change. I believe the basic working principle of the current touchscreen is that you read the X and Y resistance quite similar to two variable resistors and you get a coordinate on the screen. Min and Max can be determined using the calibration and pre-programmed in the factory. No amount of software will make it multitouch since it won't have the necessary data to work with.

I think like MMS - Mutltitouch is just overrated.

I don't miss MSS - And I use a stylus a lot when surfing so how do you multitouch with a stylus in one hand?

Just my 2 cent on this

I rather have a scrollbar:Please vote. Details below.

Re: New Firmware with QT4.6
 
@marktold, I have to disagree with you regarding MMS being overrated. It's pretty common in the Asian countries and it's usually free to receive an MMS. As for multitouch yes, it's a bit hyped up. Then again there are some advantages of having multiple inputs specially when you need to zoom, resize and provide more intuitive widget controls to the user. Multitouch is not a deal breaker as some point out, but it definitely is a bonus which I personally don't want if it means sacrificing accuracy over for.
As for the Qt having multitouch support, it's a must in any modern GUI framework and I love the pace and quality Qt is going forward.
