    Phoronix: Kinect With Qt Makes Cursor Out Of Your Hand

    Microsoft's Kinect paired with the Qt tool-kit can allow using your hand as an input device, or what the developers are calling an "air cursor" for this open-source project...

      Wow, it suddenly seems applicable. It will be interesting to see how touch screens and motion sensors will play together in the near-future.

        Yawn.
        Hasn't this already been done, and much better?

            Air cursors I love it!
            Makes everything easier to work with each other.

            Want this on all mobile phones and devices with touchscreen.

                Anyone can use The Leap to interact with Windows 7/8 or Mac OS X by clicking, grabbing, scrolling and using familiar gestures like pinch to zoom in 3D space.
                further down
                How about Linux?

                Linux support is on the agenda.
                This looks really cool

                    you can do this with a standard webcam. the "click" feature would be a lot more difficult to accomplish but you can at the very least effortlessly control a mouse pointer using any webcam or really any object you want; i've seen it done with a ~400 line python script

                      If this is true, then where's the distro with builtin support, loudly drumming that? "We have Minority Report UI!!11"

                        ...distro? who says you need an entire distro for something like this? that's like saying in order to play a DVD you must buy the DVD player, TV, speaker system, and couch all in 1 purchase. This is an optional feature that any OS could handle. I didn't look into this Qt based program but considering that it is Qt, it wouldn't surprise me if even Windows or Mac could run this with the proper drivers.

                        This sort of thing is pretty gimicky anyway, much like touchscreens. It has SOME practical purposes (like touchscreens) but overall it's an inefficient, high latency, processor demanding feature that limits your computing experience. I admit it is pretty nifty, but this isn't something to "drum" about.

                          If it worked well enough to show off, I'd expect someone to have made a demo livecd, just like the early compiz ones.

                            No, its just a simple program that controls the mouse pointer by using openCV to identify a moving object in a webcam display. There's no reason to have an entire demo OS of it - all you need is to install python, opencv libraries for python, and v4l. since most linux setups include python and v4l, all you need is opencv, which is a small install.

                            Aside from this 1 script I'm referring to, the situation shouldn't change for something like this kinect Qt thing. I didn't look into this but I doubt you need an entire live CD for it you just need a few libraries. Compiz needed a demo CD because it replaced window managers and altered your DE, this is just an extension.

                              No.

                              Dependencies
                              OpenCV - computer vision library
                              OpenNI - natural interaction library
                              PrimeSense NITE - gesture and skeleton tracking for OpenNI, free for commercial usage but requires an EULA
                              PrimeSense Kinect Sensor - Kinect drivers for OpenNI
                              That OpenNI/NITE stuff needs java...
