The user illusion is the illusion created for the user by a human-computer interface, for example the visual metaphor of a desktop used in many graphical user interfaces. The phrase originated at Xerox PARC.
Some philosophers of mind have argued that consciousness is a form of user illusion. This notion is explored by Tor Nørretranders in his 1991 Danish book Mærk verden, issued in a 1998 English edition as The User Illusion: Cutting Consciousness Down to Size. He introduced the notion of exformation in this book.
According to this picture, our experience of the world is not immediate, as all sensation requires processing time. It follows that our conscious experience is less a perfect reflection of what is occurring, and more a simulation produced unconsciously by the brain. Therefore, there may be phenomena that exist beyond our peripheries, beyond what consciousness could create to isolate or reduce them.
Famous quotes containing the words user and/or illusion:
“A worker may be the hammer’s master, but the hammer still prevails. A tool knows exactly how it is meant to be handled, while the user of the tool can only have an approximate idea.”
—Milan Kundera (b. 1929)
“In April 1917 the illusion of isolation was destroyed, America came to the end of innocence, and of the exuberant freedom of bachelor independence. That the responsibilities of world power have not made us happier is no surprise. To help ourselves manage them, we have replaced the illusion of isolation with a new illusion of omnipotence.”
—Barbara Tuchman (1912–1989)
