One room becomes many, the moment a wall moves

Dynamic Space Partitioning lets a single ballroom split into eight independently-lit rooms, and merge back, as operable walls open and close. I designed the system that models those moving walls, sub-areas, and devices into one configuration any installer can run.

The Brief

Software for a room that won't hold still

Lighting platforms assume a fixed floor plan. Partitioning breaks that assumption: the operable walls move, so the relationship between rooms, zones, and devices is fluid. A single venue can host one 400-person gala in the morning and five breakout sessions in the afternoon.

As lead designer I framed the partitioned-area concept, pitched it at the 2023 User Advisory Group, iterated the information architecture through three major versions, and delivered the configuration flow across mobile, tablet, and desktop.

Challenge

A physical system, made legible

Three forces shaped every screen, each a constraint the system had to honor, not a feature to bolt on.

01
Walls aren't fixtures
A wall is a relationship between two rooms, not a device. No object in the platform modelled "these two sub-areas merge when this wall opens."
02
Merge & split, automatically
When a wall opens mid-event the lighting must unify instantly, and re-separate when it closes, without staff recalling scenes by hand.
03
Configure once, correctly
Sub-areas, walls, joins, devices and contact inputs are a lot to set up. One wrong mapping lights the wrong rooms, so the flow had to be guided and hard to get wrong.
What It Is

A space that changes shape during the day

Partitioning divides large rooms into smaller areas with operable walls, so each room is lit on its own when closed and unified when open. It lives in hotel conference rooms, ballrooms, school cafeterias, and gymnasiums.

Approach

Rooms first, walls as relationships

The design bet was to model the space the way the people running it think about it, not the way the hardware is wired. Get the mental model right and the contact-closure plumbing disappears behind a floor plan anyone can read.

01
Sub-areas as the primary object
Each sub-area owns its own zones, devices, and occupancy; a venue manager describes the room this way, so the IA matches their mental model.
02
Walls demoted to a join
A wall is modelled as a relationship that says which sub-areas merge when it opens, not as another device to manage in a flat list.
03
Live state from contact inputs
Each wall is wired to a CCI / IRTR contact-closure input, so the Wall Status board reads each wall's real-time open or closed state, with manual override.
04
Guided once, runs itself
A 3-step wizard, sub-area names → wall configuration → devices, removes ambiguity at setup; after that the room re-lights itself as walls move.
Design Iterations

Three versions to one mental model

The IA converged left to right: from a technically-correct walls-first V1 users couldn't reason about, to a sub-areas-first hierarchy, to a consolidated wizard with live wall status.

Version 1, walls listed as the primary object, later abandoned

Version 2A, sub-areas promoted to the primary list

The Configuration Flow

Five guided steps, then it runs itself

The shipped desktop wizard takes a room from "Partitioned" to fully wall-aware, defining sub-areas, the walls between them, and the contact input that senses each one.

01
Create the Area
Tap + to add a new area, the entry point for any space being commissioned.
02
Define the Partitioned Area
Set the Partitioned type, then the wall and sub-area counts that describe the room.
03
Update Sub-Area Names
Name each room for the application so the floor plan reads in the venue's own language.
04
Define Each Wall's Joins
Pick the sub-areas each wall separates, the relationship that drives merge and split.
05
Assign the Wall Input
Map each wall to a CCI / IRTR contact input so its open / closed state is sensed live.

The Payoff, Floor Plan

Open a wall. The rooms merge.

On tablet the shipped plan maps every chandelier, cove and zone to its sub-area, assign by tapping the floor. When walls open, their devices fall under one zone's control; scenes, occupancy and daylight all follow.

Every Surface

Commission on a phone, operate on the wall

An installer configures partitions on a phone at the panel; a venue manager runs the room from a wall-mounted tablet or the web. The same three-step model, sub-areas → walls → devices, scales to each screen.

The breakthrough wasn't a screen, it was deciding that rooms, not walls, should be the primary object, and letting the wall hardware fall behind a floor plan anyone can read.
