I've already started thinking about some gestures that could be used for this, but I'm wondering, how hard it's going to be on the hand(s)? I mean with the mouse and keyboard (supposing PC gaming) the hands are resting on the table 90% of the time, with this the hand(s) will be up in the air.
...unless someone puts a nice glass table on top of that thing so that my hands could rest... could this work?
