POSCO Park1538 Exhibition Hall — Civilization of Iron

Civilization of Iron
Light following visitors

Park1538 Exhibition Hall, 1F, Pohang, Gyeongsangbuk-do
Opened to the public April 12, 2021

In POSCO Park1538's circular Civilization of Iron gallery, we tracked visitors' movements so light could follow their feet. Motion-recognition software connected to moving lights creates real-time interaction responding to walking direction and position.

A circular hall filled with wireframe gears. Each visitor has a white circle of light beneath their feet.

Born of water, fire, wind and earth,
iron, the flower of civilization

In an 11-meter-high circular hall, 360° imagery wraps the walls and floor to tell the story of iron. Within media content by d'strict and GIANTSTEP, responsive floor spotlights add an experience of walking through the space.

With every step,
light finds you

As visitors move through the hall, motion-recognition software reads their changing positions. Ceiling-mounted moving lights turn toward them, casting circles at their feet. Even with several people moving together, each light follows its own visitor.

  1. Visitors entering a broad circular floor beneath unlit ceiling fixtures
    Enter the hall

    The software reads visitors' positions as they enter the circular floor.

  2. One ceiling light tilts to cast a circle at a visitor's feet
    Light beneath your feet

    The ceiling moving light turns to place a circle of light beneath the visitor.

  3. Three people walking in different directions, each with a light at their feet
    Light follows as you walk

    The light follows each step, with one light assigned to each person.

From reading a position
to directing light

We operated motion-recognition software and linked changing visitor positions to moving-light direction. Before installation, simulations tested multiple moving targets; on site, walk-through tests aligned the visitors' movement with the light at their feet.

  1. Read positions

    Track where visitors move in real time.

  2. Control light direction

    Change the moving lights' aim to match the detected positions.

  3. Respond with light

    The light beneath each visitor moves with their steps.
