This UnMouse pad being shown at the Microsoft Research Summit looks pretty freaking awesome. It’s a super-thin, pressure-sensitive little pad that can take just about as many inputs as you care to give it — and each input contains analog pressure info. Microsoft is working with NYU to put it out there; it’s apparently cheap to make and is almost certainly able to be made in many sizes.
Trouble is it probably can’t be transparent, so it can’t be used in touchscreens. But something like this could be great for putting in cheaper devices that can’t include tech like that. I’m thinking tiny laptops!
