That's not really, what I'm referring to, though. I'm more interested in the "palette-style" interaction - say your left hand opens a menu or selects an object while your right hand can perform "manipulations" on that menu. I guess a really interesting modern spin on that would be the combination of pen and the dial wheel that come with the new Surface Studio from Microsoft. Game controllers, while also an interesting study, emerge from a totally different approach and seem to be mostly "figured out" nowadays, although even so now and then there's a different take on controller usage (e.g. the controls of Brothers: A Tale of two Sons).
