This is a powerful vision, and your team executed it brilliantly! Moving beyond gameplay to a Gamified Neural-Rehabilitation Platform is exactly how we close the gap between therapy and patient engagement. Your architecture, especially the mental reset via focus monitoring, shows a deep understanding of how neuroplasticity works. We are proud that BR41N.IO could serve as the stress-test for such impactful work. Excellent job to the whole team!

How exciting! What a beautiful idea.

Acknowledged by Hackathon Leaders & Industry Experts

The project received overwhelming positive feedback from neuroscience researchers, medical engineers, and fellow hackathon participants. The concept of merging gamification with neural-rehabilitation resonated deeply with the global BCI community, earning the Crowd Favourite nomination at the BR41N.IO Global Hackathon.

The Challenge

Developed during the 48-hour BR41N.IO Global Neuroscience Hackathon, the challenge was to create a Brain-Computer Interface application that could make a real impact in medical rehabilitation. Our team aimed to build something that goes beyond a proof-of-concept, a functional platform that could genuinely help stroke and physical trauma patients rebuild neural pathways through gamified motor imagery exercises.

Development Process

Key Challenges

Building a reliable Python/Node.js bridge to stream real-time EEG data from the BCI headset into Unity3D with minimal latency

Accurately mapping Motor Imagery signals (Left/Right Leg intents for movement, Arm intent for interaction) to in-game character controls

Architecture & Design

Custom dual-bridge architecture: Python handles raw EEG signal acquisition and preprocessing from the g.tec BCI headset, Node.js manages the real-time WebSocket streaming layer, and Unity3D receives the processed intent data to drive player movement and environmental interaction. Live cognitive focus monitoring runs in parallel, directly influencing gameplay.

Core Systems

Real-time Motor Imagery mapping with Left/Right Leg intent classification for character movement

Cognitive focus biofeedback loop, if patient focus drops below threshold, the character collapses, enforcing a mental reset

The Result

Final Product

A gamified Neural-Rehabilitation Platform engineered during the 48-hour BR41N.IO Global BCI Hackathon. Uses real-time Motor Imagery to help stroke and trauma patients rebuild neural pathways through intentional movement in a Unity3D environment. Nominated Crowd Favourite.

Key Features

Gamified neural-rehabilitation environment built in Unity3D

Real-time Motor Imagery control via BCI headset with Python signal processing

Live cognitive focus monitoring that directly impacts gameplay progression

Intentional motor imagery exercises designed for stroke and trauma recovery

Biofeedback-driven gameplay loop reinforcing sustained mental engagement

I am incredibly proud of what our team, achieved this weekend at the BR41N.IO BCI Hackathon. We didn't just build a game, we engineered a Gamified Neural-Rehabilitation Platform designed to help patients recovering from stroke or physical trauma rebuild neural pathways through intentional motor imagery. The Tech Stack: • Architecture: A custom Python/Node.js bridge to Unity. • Control: Real-time Motor Imagery mapping (Left/Right Leg intents for movement, Arm intent for environmental interaction). • Biofeedback: Live cognitive focus monitoring, if the patient’s focus drops, the character collapses, forcing a mental reset. Every successful step taken on this screen represents a rebuilt connection in the human brain. This is more than gameplay, it’s a tool for reclaiming bodily control. Massive thanks to g.tec medical engineering g.tec medical engineering g.tec medical engineering GmbH - NEVER STOP RECORDING and Dr. Christoph Guger for the opportunity to stress-test our architecture. A huge shoutout to my specialized team: tamaz skangeli, Sandro Jangidze, Giorgi Piranishvili The journey of BCI in rehabilitation is just beginning. We’re ready for what’s next. #BCI #Neurotechnology #MedTech #Unity3D #Innovation #Engineering #Rehabilitation #BR41NIO
