i remember reading in one of the hardware tear down threads that the touch controller is capable of more then just 2 touch like it is now. is this a froyo limitation? i was hoping we could unlock the multi touch capability if its not controller firmware related.
Not a froyo limit. My galaxy s running.! 2.2.1 has 6 input multi touch

Hero support up to 2 points, and the performance seems not so smooth as iphone, and the focus will shift!
Everyone could test your screen with Multi-touch Vis Test that download from market.
i9000 support up to 5 points!
who can solve this problem?
I'm going to assume it's a hardware limitation, which will never be fixed. Multi-touch on my Hero is and has always been weird.
thanks.````````````````````
Hardware limitation. It's not proper multi touch - it's a form of dual touch, but it only recognises the first finger position and the distance of the two fingers, as opposed to proper co-ordinates.
Moved to Q&A
On the Evo, some revs of the touch sensor support 5-point multi-touch, but it took a custom kernel to make this available to apps.
Does anybody know if the hardware on the Gen8 tablets (in particular the 101) is limited to 2 points, or if it could possibly do more with a custom kernel?
It would be cool to do things like piano chords with so much space available.
I don't think its possible - if you touch with > 2 fingers it looses all touch points...
the build-in touchscreen controller does only support dual touch (like the joojoo, wetab, hanvon b10 and so on)... a better one would be more expensive.
just 2 points for the gen 8
Can someone tell me what is the multitouch capability of the G Tablet? I'm thinking of buying it as it is the cheapest Tegra 2 tablet, but I'm not so sure about the multitouch. Is it 2-point multitouch or 5 point? If someone with the tablet would be so kind to just download like Multitouch Test from the Market and see how many fingers the tablet supports.
2-point.....

Is this a hardware or software limitation?
Thanks!
Just so your aware. On my gtab multitouch is only reliable when the two points are not on the same x or y axis. When zooming in for example it is necessary to pinch diagonally or else nothing happens. Other have claimed this is not an issue on their gtabs, but this has been an issue for across several roms.

Difficult to say. The kernel only gets the data for 2 (simultaneous) touchpoints from the ATmega168 microcontroller that the actual touchscreen sensors (2 Pixcir Tango 32C sensor chips) are connected to.
Can the ATmega168 uC be reprogrammed to send more than 2 simultaneous touches to the kernel? Can't say.
Do the Pixcir Tango 32C sensor chips register more than 2 fingers at the same time. Yes, very probably.
Whatever the case, you'll need a ATmega168 programmer and all the chip-specific datasheets to make it happen.
I know dual touch has been enabled on the x10. But, just out of curiosity, is there a way to get more than 2 points to pick up on the x10?

No, sadly we cannot have more than 2 points. The x10's screen is hardware capable of maximum 2 points, that's why it's called dual touch, and we have pinch to zoom because it requires only 2 fingers. 3 or more points mess up the axis. Practically X10 doesn't have multi touch, but dual touch. And it will never have more than dual touch, it's not because of the rom, or version of android, it's because it's hardware limited.
Hope i explained you ok.
It's the digitizer on the x10 it can only recognize two points simultaneously, and even with only two it's glitchy....
I thought that was the case just wondering, cause a lot of people say its " multi touch " when actually its just dual

I have a couple of tablets but my primary is my Xoom. I'd like to use the HDMI output and the USB to connect to a multitouch screen that I have. I've seen some older hacks that are resistance hardware touch screens that are more hardware. I'm wondering if this is remotely possible in the newer version of android like ICS on the Xoom.
Thanks
