It´s a little wish for live usability: To use a tablet PC as a controller besides a laptop. Metasurface could be controlled with gestures on a bigger, additional screen. On your laptop you could see the reactions on audiomulch of all the controllers and have more power.
Gestures look better than a mouse- no double click is necessary to touch a point( not drawing a mouse or arrow). With a wipe it could be react like I-Phones that the movement doesn´t stop immediatetly but float from the touching point to a point of the direction. Maybe this could be another modus than for mouse. This was a discussion in the forum, but I didn´t find it . PS WLan or Lan+ little program
