Cyberpunk vs Diegetic UI
サイバーパンク / ダイエジェティックUI
Cyberpunk comes from Visions of the Future and Diegetic UI from UI Expression. One is style and the other technique. They are reached for with some of the same intent, which is where they get confused.
Cyberpunk
Advanced technology and ruined daily life share the same frame, so the future arrives as promise and as threat.
Diegetic UI
A name for the corner of game interface design where an element belongs both to the fiction and to the three dimensional world. A 2009 master's thesis at Chalmers University of Technology, written with EA DICE, mapped game UI on those two axes and reserved the word for that corner. Health glowing on the hero's own suit is the type case.
| Cyberpunk | Diegetic UI | |
|---|---|---|
| Era | 1980s– | 2009– |
| Family | Visions of the Future | UI Expression |
| Kind | Style | Technique |
| Cues | Rainy nights / Multilingual neon / Dense cabling / Dark cities | Health or ammunition shown on the protagonist's own equipment instead of in a corner of the screen / A map the character holds up and reads while still walking, rather than a paused overlay / Panels of information projected into the air that tilt with the camera because they occupy the space / Directions given by the color of a signpost standing in the world itself |
| Best used for | Speaking of technology's light and shadow together · Thick world-building for games and film | Moving health and ammunition out of the corners of a first person game and into the world itself · Placing information in VR or in a vehicle as an object in space rather than a layer stuck to the view |
| Type | Angular sans, monospace, multiple scripts | Treat every character as printed or projected onto something in the world, so it skews with the camera. Some angles will be unreadable, so carry the same meaning in shape and color too. |
| Composition | Stack information densely on dark planes | Leave the four corners of the screen empty. Distribute information across the body, the held device, and the environment, and keep those roles fixed. |
| Material | Black, teal, red neon, raindrops | Use only materials the fiction can account for, such as a lit tube or a projected plane. The style collapses when the material stops being explainable, so settle the world first. |
| Caution | Don't use Asian cities as a symbol of otherness. Make the fictional social order concrete. | Building an object into the world and then printing controller button names on it mixes fiction with rules, and that is exactly where the thesis's own focus group reported the illusion breaking. |
