A lightweight mobile demo application that visualizes focus level in real time using simulated earEEG signals. The app is a prototype for future integration with real hardware.
We chose to build this demo because earEEG technology allows convenient and mobile recording of brain activity. Unlike traditional EEG, it can be worn daily and unobtrusively, making it an excellent tool for studying focus during real-world tasks (e.g., reading, listening, working).

Details of the project (with app examples) are available here
The prototype already includes:
- 📱 User Interface (UI) – visualization of focus level with simple charts and feedback
- 🗄️ SQLite integration – automatic creation of required tables for storing data
- 🧠 Biofeedback & recommendations – app reacts to focus level and suggests micro-actions
Next development steps:
- ☁️ Enable secure cloud storage of data (Supabase or other)
- ⚡ Simulates earEEG input for testing without real hardware
- 📦 Create infrastructure for chunked data processing
- 🔗 Connect with real earEEG hardware
- 📊 Improve signal processing (FFT, band power analysis, entropy measures)
- 📱 Extend the mobile UI with recommendations & history view
- 🐧 Linux (tested on Linux Mint 21/22)
- 📱 SDK emulator for mobile builds (Android)
- 💻 Desktop build & run via Qt Creator
- 🎨 QML – modern, declarative UI
- 💻 C++ – backend logic, data streams, signal processing
- 🏗️ CMake – build system configuration
- 🗄️ SQLite – lightweight local database for persistent storage
Download files from GitHub and open the project in Qt Creator
git clone https://github.com/humanplusplus/EarEEG_DemoApp
This is just the beginning. We’re taking this project further — until January 2026, backed by the University of Warsaw Incubator (Laboratorium Pomysłów).
Next step: real ear-EEG data and the first hardware prototype. ⚡🧠
