Motif vs Terminal UI
モチーフ / ターミナルUI
Motif comes from Platform Screen Languages and Terminal UI from UI Expression. Both are read here as style. They are reached for with some of the same intent, which is where they get confused.
Motif
Motif is the interface language of UNIX workstations, maintained by The Open Group, standardized as IEEE 1295 and shipped on more than two hundred platforms. Its own data sheet calls the look a distinctive 3D beveled appearance, meaning every part sits on a gray face edged with one light line and one dark line.
Terminal UI
The terminal look: monospaced phosphor characters on black. The VT100's green afterglow became the primal image of the computer's face, repeated from hacker cinema to modern CLI tools.
| Motif | Terminal UI | |
|---|---|---|
| Era | 1989– | 1970s– |
| Family | Platform Screen Languages | UI Expression |
| Kind | Style | Style |
| Cues | A gray face lit along its top and left edges and darkened along its bottom and right, so every part appears raised / While a control is held down the two edge colors swap and the part sinks / A thin rectangular ring is drawn around whichever control currently takes keyboard input / Scroll bars are square cornered rectangles with a triangular arrow button at each end | Single phosphor color on black / The monospace grid / A blinking cursor / Scanlines and glow |
| Best used for | Rebuilding a UNIX workstation era application for an exhibit or a technical write up · Building instrument or CAD controls where pressable and unpressable must read as relief rather than color | Developer tools packing state and next steps into one monospaced screen · Staging technical hardness or secrecy as the look of an interface |
| Type | A small sans at one fixed size, labels held to a single line, no letterspacing and no ornament inside the text. | One monospaced face where emphasis comes from weight and inversion alone |
| Composition | Windows are cut into beveled rectangles and controls are packed a few pixels apart; there is almost no breathing room, the screen is filled with operable parts. | Everything on the column and row grid, blocks separated by blank lines |
| Material | Pick one face color, derive a light edge and a dark edge from it, and paint them on opposite sides; swap the two while pressed, and never round a corner. | One phosphor hue on black with scanlines and bloom added sparingly |
| Caution | Replacing the two hard edge colors with a soft drop shadow kills the flip that signals a press, leaving decoration that merely looks raised. | Heavy scanlines and flicker cost legibility and the atmosphere ends up beating the speed that made the tool worth using. |
