CREATIVE TECHNOLOGIST — HCI × BIOSIGNALS × PLAY
Julien Quenneville
I read muscles, motion & brainwaves, and turn them into interfaces driven by the human body.

ONNX RuntimeProjects
A dedicated page for each project. GitHub icon when a repository is available.
2D-EMG-GAME
From muscle to screen. A game controller made of surface EMG: contraction strength is split into four bands, each band becomes an input, and Steam Input carries it into real games. Shown at the Festival of Learning.
Body Shape Control Suit
An adaptable, modular posture-analysis system. An e-textile suit reading trapezius EMG, Rokoko motion capture, and an AI biofeedback model trained on Z-Anatomy. My Master's thesis project.
IFTendo-Battleship
A two-player Battleship on a home-made Game Boy. One console hosts a Wi-Fi access point, the other joins as a client. Written in C++ with the Arduino IDE, on a custom PCB with an OLED screen and eight buttons.
Thoughts in Motion
An open-source platform for getting biosignals into interactive applications: EEG and EMG streamed over LSL, processed and classified in Python, then pushed into Unity or a 3D scene. Hugo Devoille's Master's thesis project, at the De Vinci Innovation Center.
EEG Rugby Helmet
A rugby helmet that measures the hits it takes. At Brain Shell I designed the new ESP32-C3 acquisition board and led the software side of the touchline dashboard, from Flutter to Tauri/Rust.
3D Room Portfolio
My previous portfolio, in two halves. An interactive 3D room you explore, and a classic portfolio site rendered live inside its screens. React Three Fiber and Blender, two repos, two deployments.
HoloExplorer
A top-down exploration game inspired by Hololive, built to learn Entity Component System architecture. Explore biomes, collect items, uncover secrets.
Hololive EN — AI Text RPG
My first in-browser LLM project. An interactive-fiction RPG with Hololive EN characters, where the story is generated on-device by WebLLM. No backend, no API calls.
Chat-Room-API
My first real-time messaging system. A React front-end and a FastAPI WebSocket back-end broadcasting to every connected client, containerized with Docker.
TRON — Network Game
My first networked game, coded on Linux. A multiplayer TRON light-cycle game for up to 4 players over a local network, in Python and Pygame.
Travel and music first: the person behind
The concerts I flew to Japan for, and the music I keep on loop.
Now playing
No setlist for this one — it was an exhibition, not a concert.
