[Q] >2 Multitouch points? - Gen8, Gen9, Gen10 Q&A, Help & Troubleshooting

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

Multi-touch problem, maybe the driver causes.

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.

Multi touch capabilities?

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.

[Q] multi touch on X10, more than 2 points?

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

[Q] 10" Android tablet with >=10 touch points?

Hi everyone,
for a project, I need to get a 10" Android tablet and the only real requirement is that it has to have at least 10 simultaneous multi touch points.
Unfortunately, it seems like this little details doesn't pop up in almost all of the specification listings on websites
So, do any of you know of a tablet that has a guaranteed number of 10 or more multi touch points?
Goddchen
Many (most) modern touch screens have exactly 10 touch points. I believe it's the industry standard for now. If not specified, probably almost every tablet will be fine for your needs.
okay, I see. Thank you.

Lenovo Yoga Book vs Chuwi HiBook Pro

Hey guys, I'm looking for a new tablet but I'm not sure how much I want to spend. I've seen this comparison around and I was wondering what's your opinion?
It's the just released Lenovo Yoga Book vs the latest Chuwi HiBook Pro.
Similar specs but different prices. Is it worth spending so much more for a slightly better processor? The HiBook Pro has a much sharper screen (2560 x 1600) and it's a lot cheaper.
I have a chuwi hibook 10.1 and it's pretty nice, esp given the price vs other windows 10 tab and Ultrabooks. Plus it has the dual boot option of Android 5.1. The tablet itself is a good value.
The keyboard docks on these chuwi tabs, and many other cheap Chinese tabs from what I've gathered, is also pretty nice, given one glaring oversight. The touchpad. It ships with no special touchpad driver, instead using the generic MS HID Mouse driver. The problem is that there are no touchpad options.. no sensitivity settings, no swipe or gesture settings. It does support 2 finger scrolling and tapping, so it does work, but it is super sensitive. the bigger problem is that Win10 has all these mouse gestures built in, so when using it, you are always activating mouse gestures, which makes it almost useless. For example, if you move your finger from top edge in downward direction, it triggers the Windows+D hotkey (show/hide desktop). This happens all the time, as does other window key shortcuts.
Chuwi says they don't build the keyboard, and have no idea who's touchpad hardware is used. So far no real solution has been offered to make the pad register as a specific device, or even utilize the ms precision touchpad driver (which would enable options for some adjustments in Windows).
So basically, if you're planning to use the tablet as a tablet, it's fine. If you plan to use a mouse all the time it's fine. But if you plan to use the integrated touchpad, you might want to consider something else. It's my understanding that many other cheap tablets are using the same keyboard, more or less, and have the same touchpad issues. My best advice is to do lots of research before you buy if this is a concern to you.

Thanks for the feedback! Really helpful.
I guess I'll go with Chuwi then, also because they're running this promotion: promotion.chuwi. com/chuwi-12th-anniversary-celebration/
So I could even get it for free! Win/Win.
