For a current project I need to simulate Multitouch screen input on a Xubuntu machine.
I have a Linux application with multiple buttons on the UI and I want to trigger them by pressing physical buttons connected to the Arduino. Because of its multitouch nature, it should be possible to press multiple buttons at once, each triggering a "touch down/up" event on the screen.
Arduino has HID mouse capability, but I need to support multiple events at once (multitouch is usually up to 10)
Certainly. Just explain how you would use a physical mouse to press 10 buttons AT THE SAME TIME. Then, we can explain how to make the Arduino-as-mouse do the same thing.

I might have expressed myself differently but the same thought was in my mind.
Teensy 3 (not sure about Teensy 2) can emulate a USB touch device. In the USB Type menu, there is "Keyboard + Mouse + Touchscreen". One of the examples is named TenFingerCircle. You can install the teensyduino code without a Teensy and browse the examples and options.
