MIT makes new experimental tactile user interface
This electromagnetic interface (called ZeroN) allows people to place objects in 3-d space, and the interface can remember where things have been placed in the past (a sort of version control).
Researcher Jinha Lee:
This reminded me of the rant by UX specialist Bret Victor about how we are tactile creatures and we work best with tactile feedback when manipulating things. This ZeroN could be a start in that direction.
