In the Star Trek fictional universe, LCARS (//; an acronym for Library Computer Access/Retrieval System) is a computer operating system. Within Star Trek chronology, the term was first used in the Star Trek: The Next Generation series.
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.
The LCARS interface is often seen used on a PADD (Personal Access Display Device), a hand-held computer.
At seven-inch (180 mm), similarly sized modern tablet computers such as the Nexus 7, Amazon Fire, BlackBerry PlayBook, and iPad Mini have been compared with the PADD. Several mobile apps were created which offered an LCARS-style interface.
CBS Television Studios claims to hold the copyright on LCARS. Google was sent a DMCA letter to remove the Android app called Tricorder since its use of the LCARS interface was un-licensed. The application was later re-uploaded under a different title, but it was removed again.
