the n900 can't have multitouch due to hardware limitation .
however , fake multitouch is possible , you touch the screen at one point and then touch it at another point , the position of the second point can be calculated , given the first point remains staitionary .
example : for pinch zoom , you keep one finger stationary and move the other finger away from it , but if you move both fingers , nothing will be detected , the screen reports the average position of all points it's touched at , so moving 2 fingers away , the screen will return the same point (no motion detected)
anyways , this fake multitouch isn't used in any applications on the n900 , except maybe a demo of the idea on youtube.

Resistive touchscreens doesnt support multitouch by hardware for now. But, software multitouch could be created which doesnt work as good as hardward support.
Check this link that shows a multi touch game for the resitive sceen on the Nokia 5800.

Would that be able to be implemented as a background process on the Maemo OS do you think?

lcuk did implement fake multitouch in liqbase a long time ago: liqbase fake multitouch
There was also another multi-touch game post (fake multitouch, by having stationary buttons and calculate the button presses based on the position of the "combined" point) on Planet Maemo some months ago, but I can't find the link right now.

Yes, a background process certainly could assume all presses are in 4 carefully-selected (to remove ambiguity) positions and resolve them accordingly -- but why in the world you would want that I don't know. It's clever, to be sure, but it's not general-purpose.
How hard is it to understand that the single pressure-weighted average of n touch locations (exactly what a standard resistive screen measures) contains less information than a list of each position? You can't just summon the missing data from nowhere!

Getting back on track now.

Another interesting question would be is. How would the phone react to tapping multipul thing's at the same time, it's just like having 2 mice plugged into the the same desktop. Surely the'd be fighting eatch other the way they do now? Sometime when you need to take down a not quickly or using the uKeyboard you kind of double tap and then the phone spazs out. I beleive that could sort that problem.

Would be nice. Hugging(multitouch) is always better than slapping(singletouch)..Isnt it?

I was wandering if anyone else thinks that a Multitouch Touch Screen would be a good feature of the N900. If anyone could create it or implement it into thier kernels with out upsetting any apps etc..?
I'd be happy to do some testing, I know it's probably not a wide used feature in a lot of App's/Games atm but that's only because we haven't got it to use it if you get what I mean.
Think about it for a second, 4 home screens sliding x <-- --> x
What about pulling them apart as a feature and the new screen pops up behined it. I.e take a snapshot then tear image then produce new home screen. I just think there are loads of cool things we could do with it. I have more Ideas too. Another one would be to use in game for the palm pre and android etc. We are reduced to what we can some with some of the thing's other phones can do.
No biggy. I suppose I'll see how this goes and if it's just me that thinks of this or others too
