Brief

A waiting room that says what the organisation does

A corridor where people queue with nothing on the walls, and a brief set in 2050. So: not a light fitting, but a piece of wall that grows as the network does.

InteractivityProximity changes the light, so the wall answers the visitor
IdentityBlue and yellow, the colours already on every NHMP vehicle
RestraintLED strips only, idle most of the day, bright only when read

Research

Understanding a force we had never designed for

Six methods, one week, three findings that survived.

Findings

Three that reached the wall

01Expansion is the story, so the piece has to grow, and spill past its frame.
02The DLA office is where citizens meet the force. Cheapest place to shift perception.
03They already lead on technology, so a sensor-driven wall reads in character.

Two journeys through the same corridor

Renewals and first tests split at the token desk. Both spend their longest stretch waiting.

Site

The building already tries to tell this story

The corridor already had framed motorway photographs, and a scale road model sat near the lobby. People stop at the model, not the frames.

So: the wall between them, movement as the difference. Neon marks where it went.

Utilisation of spaceIntegrating into the existing circulation, rather than adding furniture, was the cheapest way to change the wait.

Concept

The network, abstracted

Pakistan is etched once, as a thin outline. Everything that glows sits inside it: spheres for cities, rods for the motorways between them, sphere size following the weight of the city. The network keeps growing, so the composition spills past the border on the left.

How it started

Four light studies before any hardware

Five words, then flat digital maps: how much has to glow before the shape reads as Pakistan, how little before it reads as growth.

Study 01Every node dark; only the network geometry, to check the map still reads
Study 02Two cities lit, blue and yellow, enough to suggest movement
Study 03Weighting by city size, the biggest node pulling the eye north
Study 04The pathway lit end to end, the state we kept for engagement
04
Form

Flat from the front, a relief from the side

The nodes sit at four depths off the face. Head on, it reads as a map; from down the corridor it becomes a lattice standing off the wall. That is what catches people from the doorway. Three materials do the whole job: a plywood frame painted NHMP blue, polycarbonate pipes for the motorways, and illuminating spheres for the cities, 54 by 54 inches, only two inches deep.

Light states

Three states, one sensor

An Arduino drives the strips; an ultrasonic sensor reads how far away the nearest person is. Nothing else is needed to make the piece feel alive.

Interaction

Storyboarded from the doorway in

My group member, Hafsa, drew the storyboard before modelling anything: a visitor catches the glow at the edge of vision, walks over, and the piece switches from blinking to a continuous white run, close enough to trace a route with a finger. Six scenes and a transition loop were storyboarded in total, so the light never has to be explained to anyone waiting.

Scenario boardOne approach, six scenes

Nothing here is ambient. Every change of light is triggered by where the nearest person is standing, and every state means something: dark is daytime, blue and yellow is the force at rest, white is the network being read.

Daylight, offNothing draws attention. The relief still holds the map on shadow alone, so the wall never reads as a dead screen.
City spheres blinking blue and yellowScene 02
Idle, blue and yellowWith the corridor empty, cities pulse one at a time in NHMP colours, a slow heartbeat, under two watts of visible change.
Two visitors noticing the piece from a distanceScene 03
Noticed at three metresThe blink is what catches people mid-queue. The sensor has them, but the piece holds back until they commit.

Engaged, white runInside a metre the whole network runs white, city to city, at reading brightness, close enough to trace a route with a finger.
The lit installation seen from the seatingScene 05
Held while readThe white state stays as long as someone is there. From the seating it reads as a lit relief standing off the wall.
The installation settling back to idleScene 06
Released, back to idleFour seconds after the last person leaves it fades back to the blink. No switch, no staff, no attention needed.
Transition loopIdle and engaged are the only two loops on the board. The transition between them is a two-second ramp, so the wall never flickers or startles anyone waiting.

Build

Eleven parts, one wall fixing

A back box takes the electronics; the front panel is drilled for every node so the rods locate themselves. Four sphere diameters, a handful of rod lengths, the whole network is a kit of repeated parts.

Making it

Built at full size, node by node

Panel painted, every node drilled and labelled, strips threaded from the back. The whole network is a kit of repeated parts, so it went up in the order the map is read.
