Matrix

Light that follows an object.

An LED matrix, a diffuser and Hall effect sensors turn a moving magnet into a physical interface for light.

Prototype in development.

A hand moves a magnet above the Matrix prototype while the light responds beneath it

02 / The principle

From soft field to precise response.

Bring the magnet close and the diffused light resolves into a ring. Move it across the surface and the light follows, making a digital system feel physical, tactile and calm.

03 / Current direction

An open-ended physical interface.

The prototype explores how a moving physical object can shape light in real time. Its final use and form remain deliberately open while the interaction, sensing and diffusion are refined.

04 / Construction

Built as a layered prototype.

The current prototype combines a P3 64 × 64 LED matrix with an ESP32 and TMAG Hall-effect sensors. A 1.2 mm translucent milky polycarbonate sheet diffuses the individual pixels, while a 3D-printed holder keeps the layers aligned.

The polycarbonate sheet turns individual pixels into a continuous field of light.

The sensed magnet position can resolve the light into a small, local response.
