Years before personal computers and desktop
information processing became commonplace or even more
practicable, Douglas Engelbart had just invented a number
of interactive, user-friendly information access the systems
that we take for granted today: as the computer mouse,
windows, shared-screen teleconferencing, hypermedia,
groupware, and more.
Engelbart’s inventions were well ahead of their time,
but have been integrated into mainstream computing as
industry and capabilities have increased. It was not until
1984 that the Apple Macintosh had popularized the mouse;
but today it is difficult to us imagine a personal computer
without one. And the huge success of Microsoft’s
Windows95 proves that the Engelbart’s original windows
concept has also to become a virtual necessity.
Engelbart now works out of the Bootstrap Institute,
which one he founded, where he is an inventor and a
consultant in multiple-user business computing. His current
focus is on a such type of groupware called an “open hyper
document system,” which may one day to replace paper
record keeping entirely.
