The BCI That Started It All: Christoph Guger’s First Brain-Computer Interface

In this video, Christoph Guger takes you back to the origins of modern Brain-Computer Interface (BCI) technology and introduces the very first BCI system he developed in 1997.

At a time when EEG amplifiers were closed systems designed only for offline recordings, Christoph set out to solve a fundamental problem: accessing brain signals in real time. Using an 8-channel EEG amplifier, a National Instruments data acquisition board, and a custom MATLAB-based software interface, he developed one of the first real-time BCI systems capable of streaming EEG data sample by sample.

This breakthrough laid the foundation for the first biosignal APIs, real-time neurotechnology applications, and many of the BCI systems used in research today.

The video also showcases the fully portable BCI prototype developed in 1998, where a custom EEG amplifier was integrated directly into a Compaq Armada laptop. The system enabled real-time brain signal acquisition and control of external devices long before wearable neurotechnology became mainstream.

More than a piece of engineering history, this prototype represents the beginning of a vision that would later become g.tec: providing researchers with direct access to biosignal data, enabling real-time Brain-Computer Interfaces, and creating an open ecosystem for neuroscience innovation.

From an 8-channel EEG system to today's high-density Brain-Computer Interfaces, this is where the journey began.
