Faculty 3 - Mathematics and Computer Science: Cognitive Systems Lab

Welcome to the Cognitive Systems Lab!

At the Cognitive Systems Lab (CSL, group of Prof. Tanja Schultz) we focus on human-centered technologies and applications based on biosignals, such as capturing, recognizing, and interpreting speech, muscle, and brain activity.

In the area of speech processing we perform research on algorithms and tools to rapidly adapt speech and language processing systems to new domains and languages.

Furthermore we investigate the interpretation of biosignals for the purpose of intuitive and efficient human-machine interfaces. Currently we develop a variety of interfaces and applications based on electromyographic, electroencephalic and biomechanic signals.
