Dr. Lukas Mecke

Forschungsinteressen

In meiner Forschung beschäftige ich mich mit Verhaltensbiometrie und ihrem Nutzen für die Mensch-Maschiene Interaktion. Genauer geht es darum Systeme anhand des Verhaltens ihrer Benutzer zu adaptieren. Ein weiterer Teilaspekt ist es, Sicherheitskonzepte durch Nutzung von Biometrie benutzbarer zu gestalten.

Darüber hinaus verfolge ich Nebenprojekte aus den Bereichen maschinelles Lernen, Bildverarbeitung und Eye-Tracking.
