But this approach didn’t work—the brain is too dynamic, and models trained without real-time adaptation failed in practical applications.
Christoph took a completely different approach. Instead of long training phases, he focused on a real-time system that could adapt quickly. He designed a process where the BCI would train for just five minutes and then immediately provide feedback. This instant reinforcement allowed users to learn and improve their brain control within a short timeframe. The results were groundbreaking, proving that real-time adaptation was the key to successful BCI applications.
The biggest challenge for Christoph was convincing the scientific community that real-time BCIs were not just possible but necessary for practical applications. Many researchers were deeply invested in their offline models. However, by demonstrating real-time control in communication, motor rehabilitation, and cognitive assessments, he proved the effectiveness of real-time BCI. Today, this approach is standard practice in the field, and it laid the foundation for the high-performance BCI systems g.tec develops today.
