Humans need better ways to interact with computers in three dimensions. Now computer scientists think they’ve come up with one.
The way in which humans interact with computers has been dominated by the mouse since it was invented in the 1960s by Doug Engelbert. A mouse uses a flat two-dimensional surface as a proxy for a computer screen. Any movements of the mouse over the surface are then translated into movements on the screen. These days, a mouse also has a number of buttons, and often scroll wheel, that allow interaction with on-screen objects.
