MPX already supported multiple input devices. Which blows pretty much all assumptions in user interfaces (input) out of the water. Now I’ve gone one step further and added support for multi-touch displays. Have a look at this video: http://www.youtube.com/watch?v=olWjnfBoY8E Upfront: I did not build some kind of touchscreen or tracking system. I did not build some kind of gesture recognition system. I built the stuff in between.A while ago I started thinking about how multi-touch and gesture support could look like. Looking around on the web and in the research literature, I found that all the multitouch systems are a hack (I’m talking about software integration here, not the hardware!). Multi-touch support needs to be in the windowing system. Any client-side approach is wrong. (Feel

The Multi-Pointer X Server (MPX) is a modification of the X Server. A standard X Server only provides one mouse cursor (pointer) and one keyboard focus, regardless of the number of input devices connected. MPX provides the user with multiple mouse cursors and multiple keyboard foci. Multicursor applications have been developed in the past but MPX is the first implementation of a multicursor windowing system (or a multicursor X server).MPX devices are independent. Each cursor is a true system cursor and different pointers can operate in multiple applications simultaneously. This allows for two-handed interaction and/or collaboration on a single display. MPX is compatible to legacy applications such as the GIMP, the Firefox web browser and numerous other applications. Keyboards provide multiple keyboard foci. So you
