    MPX is multi-point, not multi-touch.

    They're not the same, but it's a very broad category. Apple seems to like throwing out these very broad patents on very obvious technologies.

    Windows 7 has multi-touch. I'm hoping, if Apple does hold such a patent, that it'll try to enforce it against Microsoft. They can handle it and let everyone enjoy

      MPX - yes it's multi pointer - but what are they doing?
      TOUCHING THE SCREEN!!

      Go look up the information before blindly replying!

      Linux had TRUE multi-user, multi-touch screens ages ago.
      Funny how Windows and Apple are just cottoning on and actually using all this publicity to push something that was seen and proven years ago...

      Almost like they were waiting for the GPL guys to iron out all the bugs (and the tech price to come down of course).

      Now we're getting proper touch-screens (resistive layer/whatever) then I see it becoming more prevalent, and the image of Linux being that of the runner-up still being true.

        That video does not show multi-touch.

        Multi-point + touch != multi-touch.

        In multi-point touch, each touch is treated as a separate pointer. That's what you see in that video. Multi-touch treats separate touches together as gestures. You know how on a MacBook, you can pinch your fingers together/apart to zoom, running two-fingers across the pad will scroll, three will navigate, etc. With multi-point touch, swiping two fingers down would move two cursors down on the screen, not scroll.

        Multi-point touch is undoubtedly awesome, but it's not multi-touch.

          Quite true, I stand corrected.

          I thought I remembered that vid having multi-touch on the map, but it doesn't.

          I was also thinking about the Jefferson Han stuff - back in 2006.
          Of course that is just an SDK which looks like it actually runs on Windows (Perceptive Pixel) - but I wouldn't be 100% sure.
          Half of the earlier FTIR was on Linux, while the other half was done in Flash IIRC.

          I also think the progression from resizing a window (as shown in the video) is not such a big leap away from "guestures".

          I think that a patent for multi-touch on a specific device (which I'm thinking Apple/MS would do) is totally idiotic.
          Multi touch on a wall, is the same as multi-touch on a floor, is the same as multi-touch in your pocket (ignoring the fact you'd have to group the 'multi-touch'es in different sized circles in each).

          .. Sorry, I ramble..

            I do not really like touching the display all the time. Maybe usefull for little devices. Or do displays clear now themself from fingertips

              But that's just 1 way of inputting multitouch commands, and quite frankly, I think the one they had available.
              What do you think about Apple's (and some netbooks', these days) multi-touchpads?

                Multi-touch is also incredibly useful for trackpads ^_^

                I see someone else commented on that before me. Whoops!

                Yeah, the MacBook's multi-touch is incredible, although a little too prone to error (particularly trying to right-click with two fingers).

                  I just want to say that mac is not the first multitouch pad and the only one touchpad proposing this feature.

                  I'm on a asus laptop and here is the default multitouche :
                  3 thingers mean right click
                  2 thingers mean middle click (or scroll if you slide)
                  1 = select or clic
                  etc... with of course the default scroll on right side and bottom etc.

                  In my school class, half of the users using linux have this feature enabled. (I want to precise is not the case under windows...) "driver missing feature perhaps...

                    This actually works out-of-the-box with linux? Sweet.
                    How about pinching your fingers and stuff like that? I guess it doesn't work with any apps by default, but does it at least create some kind of key-event or similar?

                      Yes it works by default.

                      Didn't tried as you said there's no apps using it.
                      But I think everything is possible since it can detect 3 thingers to do right clic and 2 thingers scrolling...
