There was once a
time when humans couldn’t interact with computers except via punch cards. Since
then we’ve upgraded to flashing green cursors demanding lines of code, then to
the point-and-click graphical user interface pioneered by Xerox, and finally to
the touchscreens of tablets and smartphones. Each step of the way computers
have become more intuitive and more focused on natural human gestures.
Leap
Motion takes this evolution to its logical end, enabling people
to interact with computers using hand gestures alone. The $80 sensor tracks the
movements of all ten fingers down to one hundredth of a millimeter and expands
the largely 2D interaction of touchscreens to account for a third
dimension–depth. The result is an interface straight out of science fiction. [Forbes]
