From Wikipedia, the free encyclopedia
In the Star Trek fictional universe, LCARS (an acronym for Library Computer Access/Retrieval System, pronounced /ˈɛlkɑrz/) is a fictional computer operating system depicted in the Star Trek television series and motion pictures. Within Star Trek chronology, the term was first used in Star Trek: The Next Generation and in subsequent shows. In a real-world context, "LCARS" is frequently used to describe the style of the computer displays of the LCARS system, especially the screens from The Next Generation. The design is popular among Star Trek fansites.[original research?]
[edit] Production
The LCARS graphical user interface was designed by scenic art supervisor and technical consultant Michael Okuda. The original design concept was influenced by a request from Gene Roddenberry that the instrument panels not have a great deal of activity on them. This minimalized look was designed to give a sense that the technology was much more advanced than in the original Star Trek.[2] The early display panels were made out of colored Plexiglas with light behind them, a technique that can produce complex-looking displays cheaply. As the show progressed, use of animations increased. Most were displayed on video equipment built into the sets.[citation needed]
On Star Trek: The Next Generation, many of the buttons were labeled with the initials of members of the production crew.[1]
