Device 01 — in development since 9 December 2023

Step in place. Move in game.

VIZIR COLIBRI is a two-sensor VR runner. No treadmill, no faked keyboard input — the device registers in SteamVR as a real controller.

The signal path — from leg to game

2 × M5Stick S3 → firmware → server → calibration → steamvr → unreal → polish → app

4 of 7 modules done · release — January 2027

Modules

Each module is one link in the chain. The signal travels exactly as far as the chain is built.

ESP32 firmware
done

Streams raw and angular data as UDP packets over Wi-Fi.
- No more WASD keyboard emulation — movement is no longer reduced to key presses.
- Transmission runs over Wi-Fi, no cable to the PC.
Processing server
done

Receives packets, processes them and packs them for the other modules.
- A single entry point: everything downstream works with prepared data.
Calibration
done

Separates a step from everything else the legs do.
- Crouching, jumping, picking something off the floor, scratching one leg with the other or stretching are no longer read as forward motion.
SteamVR driver
done

A custom driver: the system sees the device as a real VR controller.
- The game needs to know nothing about VIZIR — it receives an ordinary controller.
- Motion is generated from walking in place through the processing server.
Unreal Engine plugin
in progress

The backend is done. Debugging and field testing are underway.
- Direct integration for developers for whom the plain-controller mode is not enough.
Module polishing
planned

Bring firmware, server, driver and plugin to a state fit for other people’s hands.
Desktop app
planned

The last module: flash the device, calibrate, pick a platform and a game — in one window.
- Device flashing
- Calibration
- Platform and game selection

VR gloves with haptic feedback

The lab’s next project. Details after Colibri ships.

One person builds this device. Support speeds up the release directly.
