That's an excellent point, Helge. I just tried it, and it works quite well.
The cursor doesn't go exactly to the midpoint, but I would say it's
definitely usable data. It moves almost exactly as expected.

Testing is easy - no expertice needed.
Edit /etc/X11/Xserver
You'll find the parameter list for the xserver under a GTA02 (or GT

This has been discussed multiple times since last ~15months.
The basic assumption a "middle-point" when touching with 2 fingers might be
anyway exactly in the middle is incorrect. It depends on pressure of each
touchpoint.
There have been many different opinions about feasibility of this approach

I think the jitter you should see with multitouch should be quite
different from finger moves: much hi

FWIW, there's another source of info that might be used: jitter.
When you have two fingers pressed, not only the reported position is
more-or-less the middle point, but it's also jittery.
So you could detect such jitter as a tell-tale of "multitouch" and then
use the jitter itself (orientation and
that is why may be 2nd way (raising 1st finger up after 2nd reached the
screen, so there are 2 jumps in coordinates: d/2, and d/2 in a single
direction) might be preferable way -- then you drive your 'multitouch'
mode with any gesture you like while assuming that 'other' finger is
still in the orig
Ahh, right, of course. You just have to remember to keep one finger still.

you can do rotation as well -- just a little bit of 'logic' to decide
either it is a linear or circular motion (of 2nd finger in respect to
the 1st one)

I have wondered if this was possible before, and I don't see why it can't be
implemented, but it is limited as the only motion it could really detect (I
would think) is moving the fingers closer or further, and if you move both
fingers apart at the same rate, the midpoint doesn't move, so you have
