Kooperationen

Im Rahmen der Bremen Big Data Challenge 2024 arbeitet die BBDC mit dem Human Centered Systems Lab (H-Lab) des Karlsruher Instituts für Technologie (KIT) zusammen. Diese Kooperation ermöglicht es uns, hochwertige Daten für die Aufgabenstellung der Multi-Klassen Klassifikation bereitzustellen.

Die Aufgabe der Challenge besteht darin, anhand von Biosignalen Emotionen und Kontext-Informationen vorherzusagen. Diese Daten wurden auf vier Jobmessen mit Smartwatches von 54 Proband:innen erfasst. Die Smartwatches zeichneten kontinuierlich Bewegungsdaten über Beschleunigungssensoren auf und erfassten Photo-Plethysmographie (PPG) Daten, aus denen die Herzrate und die „inter beat intervals“ (Ibi) berechnet wurden. Während des Messebesuchs wurden die Proband:innen zudem regelmäßig nach ihren Emotionen und dem entsprechenden Kontext gefragt.
