Star Trek LCARS

LCARS — the Library Computer Access and Retrieval System — is the touchscreen interface Michael Okuda designed for Star Trek: The Next Generation in 1987. Built from softly-rounded color blocks and sweeping curved "elbow" frames, it reads from a pure-black backlit console: warm orange and tan capsules glowing beside cool violet and blue ones, with thin colored rails and right-aligned numeric tags threading between them.

The system is resolutely flat — no gradients, no bevels, no skeuomorphic chrome. Its identity lives in the geometry: pill-shaped Okudagram buttons, generous black negative space, and the iconic elbow that bends a header bar down into a sidebar in one continuous radius. It is a fictional UI that became one of the most recognizable graphic languages in television.

LCARS（图书馆计算机访问与检索系统）是 Michael Okuda 在 1987 年为《星际迷航： 下一代》设计的触控界面。整套语言由柔和的圆角色块与大弧度的「弯肘」框架构成， 从一块纯黑的背光控制台读起：暖橙与沙色的胶囊按钮和冷紫、冷蓝的色块并排发光， 细细的彩色分隔轨与右对齐的数字标签在其间穿行。

它彻底是平面的——没有渐变，没有斜面，没有拟物质感的光泽。它的辨识度全在几何： 药丸形的 Okuda 色块、慷慨的黑色留白，以及那条标志性的「弯肘」——把顶部横条用 一段连续半径折下来接到侧栏。它是一套虚构的界面，却成了电视史上最易辨认的图形 语言之一。
