Microsoft's Linux MPX VS Surface
A distinctive feature of MPX or Multi-Pointer X is the ability to use multiple input devices at the same time. Having a regular computer and any number of mice and keyboards connected to the system, any number of users with one or several applications can work on it simultaneously. In addition, according to Wearables.unisa.edu.au, when you connect MPX Linux to the Mitsubishi DiamondTouch display table, it all turns into a multi-user surface that can recognize not only touches, but also gestures. The main difference between such a system from Surface from Microsoft is that MPX in combination with DiamondTouch can identify up to four different users, while Surface from Microsoft does not have such capabilities.
In the video below you can see this alternative multi-touch surface.
Thanks to all.
