Problem

Transit environments are high-stress, high-motion, and multilingual. Riders and operators need information that's immediately legible and behaviorally consistent, especially during disruptions.

Goal

Build a system that doesn't just standardize UI—it calmly guides people through complex environments and makes advanced autonomy easier to understand across product, operations, and storytelling.

Core Thesis

Glydways vehicles run with no driver and no staff, so the interface has to do their job. Lumasis is the design system that makes that possible: one set of values the rider, the operator and the vehicle all read the same way.

Perception

The vehicles don't see the world the way people do — they see sensor data. The visual system is built from that machine perception, not layered on top of it afterward.

Over two years, that perception became one tokenized foundation — color, light, glass, depth, type, icons, messaging and accessibility defaults — shared by every surface a rider or operator touches.

Six views of the Lumasis system — the guideway track and Build control, the Blue Haven to Nova Purple light ramp, a live route comparison against ride share and bus, the vehicle software mark, the cabin mood and climate controls under construction in Figma, and an arrival Live Activity on iPhone.

Principles

The principles keep that machine-built language human. It grows from how the vehicles see, sense and decide, but it is built for the people who rely on them.

Human

Rounded shapes, conversational micro-copy and organic motion instead of abrupt transitions.

Oasis

Deep negative space and blur keep attention on what matters right now.

Flow

Components morph and adapt, taking the rider from booking to boarding without jarring context switches.

Forward

Predictive states surface actions, like opening doors or adjusting climate, exactly when the rider needs them.

Parameters

Type and pictograms come from Metro and stay fixed on every surface. Color is different: with no driver on board, it carries what a driver would otherwise say — which line, what's next, what needs attention. So color is the one parameter built to adapt, and light, glass and depth all derive from it. Pick a color, a glass and a depth below to watch the whole stack follow.

Color

Glass

Depth

Read from the bottom. Color is the value Metro hands down; light is that color once the glass sits over it, which on a dark surface lands darker — hence the negative delta. Every parameter is picked rather than dragged: nine families, four grounds, five depths, and nothing in between any two of them. The grounds are ordered by density rather than by name — .045, .20, .30, .44 — so both material rows run the same direction and the surface gets heavier toward the right. Only Tinted takes its cast from the family; the other three are fixed materials, so stepping the color moves one ground and leaves the rest where they are. Every value shown is a shipped token.

Token Architecture

The vehicles already speak in data, so the tokens had to as well. Every name is derived from its value — family from the HSL hue, step from the HSL lightness — so the token file reads the same to a designer, an engineer and a model. AI did the translation work: it turned the parameters into tokens and mapped them against ADA and WCAG requirements.

Color & Light

One family read at two levels. Color is the flat, brightest shade the Metro standard hands down; light is that same color through glass at 34% — subtractive, so on a dark surface it lands darker.

Rejected

A parallel palette for dark surfaces. Doubles the token count and lets the two drift apart.

Consequence

ΔL is the number the pair is checked on: 18 to 30 points in every family, which is also the band that clears AA.

Depth

Screens stack — a sheet over a panel over the ground — and something has to say which one is nearer. Here that is a single number: opacity, five steps, .05 → .40. The blur behind it never changes.

Rejected

A parallel blur ladder stepping down as priority rises. Two properties expressing one idea, disagreeing at the edges.

Consequence

Depth is a single number an engineer can read off a token, and blur became a function of velocity rather than a decoration.

Nomenclature

Token names come from the value itself — the family from where the hue sits, the step from the lightness. Two designers naming the same swatch independently arrive at --lum-blue-52.

Rejected

A curated semantic vocabulary. Readable on day one, contested by month three.

Consequence

Naming stops being a review topic. The token is checkable against its own value.

Token names are derived, not assigned. The stem is the family and the step is the HSL lightness, so --lum-blue-52 states its own value and two designers naming the same swatch independently arrive at the same token. The swatch is the stack from the diagram above, seen edge-on and in the same order: 01 color at the base, 02 light, 03 the glass ground, 04 depth. Color is the flat, brightest shade the Metro standard hands down; light is that color seen through refractive glass at 34%. Bands 02 and 03 carry no visible seam because they are one value reached two ways — 02 painted from the stored hex, 03 composited live in the browser — and that agreement is the premise, drawn rather than asserted. The application is subtractive: the surface is dark, so glass takes lightness away and the delta runs negative. ΔL is the number the pair is checked on, 18 to 30 points in every family, and that band is also what clears AA. Depth is carried by opacity alone — .05 · .11 · .19 · .28 · .40, against a blur that does not change. Every translucent value here composites over the page ground, #0E0E0E, and never over the plate it sits on, so a token reads the same here as it does in the figure. Blur belongs to motion, where it measures the gap between a moving object and the trail it leaves.

Accessibility

With no staff on board, nobody is there to help a rider who can't read a screen, so accessibility has to live in the interface itself.

Contrast

A dark theme with glowing accents has to clear WCAG AA[1] on every primary text and control; each applied value sits 18 to 30 points of lightness above its core.

Glass

Frosted, Dark, Tinted and Prismatic all carry text at the same light values, so contrast doesn't reset depending on which surface a control lands on.

Material : Glass

Glass is the one material Lumasis does not define on its own terms. It is authored as a Figma tool built on Apple’s Human Interface Guidelines[2], with refraction, depth, dispersion, frost and splay carried as named values rather than approximated by eye, so a designer specifies glass the way the platform specifies it. That is what lets the same pill render on the Dynamic Island and the Lock Screen without being rebuilt for either.

Live Activities

Everything to this point holds on screens Glydways controls. The arrival follows the rider across the Dynamic Island, the Lock Screen, and StandBy[2], so one activity has to hold from a compact pill to a full screen. The track, the position on it, and the time never drop, and the route’s gradient carries the line identity at every size. That is one rider reading one vehicle; the control room reads two hundred at once.

Operations Command & Control

The control room is where the autonomy is supervised. An operator watches two hundred vehicles move across three circuit maps; the map carries position and nothing else, and everything a vehicle reports — and everything the system infers about it — opens in a window when the operator selects a dot. Status built into the dots was rejected: legible at five vehicles, unreadable at two hundred.

Components

The Outcome

A rider on a platform can tell what the vehicle is about to do, and an operator watching two hundred in motion can tell which one needs attention. Both are reading the same tokens at the same lightness thresholds. Nothing was translated for either of them, which is the whole of it — a value that names itself does not need an interpreter on the way to a screen.

With no one on board, the interface is what explains the vehicle. A rider on a platform can tell what it is about to do, and an operator watching two hundred in motion can tell which one needs attention — both reading the same tokens, with nothing translated in between.

A living system where light flows through — a refuge of clarity in complexity, over an image of an autonomous transit vehicle in a neon-lit tunnel
