Interactive Moving Surface for a Circus Performance

Context

Gamgie, a creative technologist and artist, collaborated with the contemporary circus company La Tournoyante during the research phase of an interactive stage show. The team explored the use of the Augmenta tracking system on a unique mobile and magnetic surface, designed to create a captivating experience where visual media reacts in real time to performers’ movements.

This project sits at the crossroads of circus performance, interactive visuals, and dynamic scenography.

Artistic & Technical Challenge

The stage for this project wasn’t a typical flat floor. It was a 6-meter by 4-meter metallic plate, mounted on hydraulic actuators. It could tilt anywhere between horizontal and vertical, offering a dynamic surface in constant motion. Performers, wearing magnetic shoes, moved fluidly across this terrain — climbing, sliding, and suspending themselves midair.

But such a surface comes with unique technical challenges. Traditional camera-based tracking systems require static environments or frequent recalibration. In this case, the interactive surface itself was never in the same orientation twice.

“The challenge wasn’t just about tracking people, it was about tracking their feet on a surface that never stayed still,” explains Gamgie. “Most camera setups break as soon as the environment changes shape. We needed something more robust — and simple.”

The Augmenta Solution: Embedded Tracking for Mobile Surfaces

To meet these demands, Gamgie deployed Augmenta’s Pro tracking software system paired with a SICK LiDAR sensor. Unlike traditional systems, Augmenta offers markerless tracking with no wearables, enabling full-body detection using a single, high-precision LiDAR sensor and an intuitive calibration interface.

The installation process was designed for efficiency:

• A SICK LiDAR sensor was mounted directly onto the moving surface
• A single RJ45 cable carried both power and data via PoE
• Augmenta’s quick-clamp mounting arm made hardware positioning effortless
• Calibration was completed directly in the Augmenta interface
• One sensor to start with so the Augmenta Pro software version was used instead of the traditional powerful servers

“The brilliance of Augmenta is in its versatility,” Gamgie shares. “Usually I work with lots of sensors and the Augmenta servers. This time I needed a something simple and lightweight, a sensor, and the software — it was all I needed. I could be up and running and calibrate in minutes. That’s exactly what this kind of project demands.”

Because the sensor was physically attached to the platform, it moved in perfect sync with it — maintaining spatial consistency without the need for recalibration, even as the stage rotated or vibrated during rehearsals.

Calibration & Implementation

Over several days of show development, the Augmenta system demonstrated exceptional performance:

• Multi-point detection enabled rich, simultaneous interaction from multiple performers
• Robust stability ensured reliable tracking, even during high-vibration movements
• Fast setup and minimal gear made the system ideal for touring shows and mobile installations
• Flexible detection tuning allowed Gamgie to configure the system for complex props, like chairs or groupings

Even in moments of occlusion — where objects or performers briefly blocked the sensor — Augmenta’s tracking held up remarkably well. A second sensor could be added in future setups to extend the coverage zone for even more resilience.

“This was immersive tech at its best — lightweight, responsive, and powerful,” Gamgie reflects. “I was able to build an interactive space that responded to movement without compromising the artistic vision.”

This collaboration didn’t just solve a technical challenge, it opened new creative doors.

The ability to track movement on a dynamic, gravity-shifting surface allowed for truly responsive scenography, where the visuals became part of the choreography. Vortex-like motion trails, dynamic projection mapping, and performer-driven animations were all made possible — thanks to Augmenta saving time on the tracking and tech calibration.

The system’s modular setup, portable design, and rock-solid calibration make it ideal not only for circus, but for any live performance, museum, or event space looking to introduce real-time interactivity with minimal infrastructure.

Conclusion

Through this innovative use of Augmenta’s tracking system, a complex and mobile circus stage was transformed into a fully interactive performance environment in just a few days.

The system’s robust design, ease of use, and adaptability make it an ideal solution for creators working in non-traditional spaces. It enables artists to embed responsive visuals directly into the choreography and scenography, without compromising fluidity or creative intent.

This project illustrates how cutting-edge tracking technology can be an invisible ally in the world of contemporary circus, enriching narrative and movement while adapting to the unpredictability of live performance.
