Tools like Resolume Arena, MadMapper, or built-in calibration tools in TouchDesigner ensure the projected image aligns perfectly with the physical space and tracking bounds. Step-by-Step Installation Guide Step 1: Site Survey and Calibration Planning
Map the thermal camera’s pixel coordinates to the projector's output coordinates. This ensures that when a participant steps on a specific physical spot, the digital effect appears precisely under their feet.

Convert the thermal grayscale feed into a binary black-and-white image. Set the lower threshold boundary to approximately 30°C (86°F) to filter out cold ground surfaces while keeping warm human profiles stark white. A successful digital playground keeps users engaged by
Launch the software and enter your activation key to register the installation. 3. Calibration and Configuration
The projector and the thermal camera must share the same field of view. Developers use a calibration grid to map the pixels of the thermal sensor directly to the pixels of the projector. When a user steps on a spot, the system knows exactly where to project the response. If you share with third parties, their policies apply
Mount thermal cameras overhead at a 45-degree to 90-degree nadir angle. Lenses with a wide FOV (90°–120°) reduce the number of cameras needed to cover the playground footprint.
Interactive digital playgrounds are transforming public spaces, museums, and educational environments. By combining motion tracking, thermal imaging, and projection mapping, these installations create immersive environments that respond directly to human presence. Setting up a "digital playground" based on body heat involves integrating specialized hardware and software to map physical warmth into real-time digital art.
