The Cognitive Systems group at Reutlingen University develops trustworthy, human-centered AI systems that combine machine learning, computer vision, multimodal sensing, and cognitive modeling. Our research focuses on robust perception, uncertainty-aware decision-making, and adaptive human–machine interaction, supported by immersive experimental environments and real-world sensor platforms.
We translate methodological advances in interactive learning and multimodal system modeling into impactful applications — from autonomous mobility and inclusive assistive technologies to movement science, life sciences, and environmental monitoring.
Our mission is to design intelligent systems that are not only technically advanced, but also reliable, transparent, and beneficial to society.
The Cognitive Systems group develops trustworthy, human-centered AI systems with a strong methodological foundation:
Trustworthy AI & Uncertainty Quantification
Robust perception and decision-making under ambiguity, including AI-based sensor degradation estimation and safety-aware validation.Human-Centered AI & Cognitive Modeling
Computational modeling of perception and behavior, human-in-the-loop systems, and ethically responsible AI design.Human–Machine Interaction (HMI)
Adaptive, multimodal interfaces and real-time user-state estimation, validated in immersive and sensor-rich environments.Interactive & Continual Learning
Learning from human feedback, data-efficient adaptation, and cross-domain transfer learning.Multimodal Perception & Sensor Fusion
Vision-based tracking, movement and behavior analysis, and real-time fusion of heterogeneous sensor systems.
These methods are supported by advanced experimental infrastructures enabling realistic yet controlled system validation.
The methodological expertise translates into several high-impact domains:
Autonomous Systems & Mobility
Autonomous driving, perception assistance systems, adaptive HMIs, and inclusive mobility solutions.Inclusive & Assistive Technologies
AI for accessibility, human-aware automation, and participation-enhancing systems.Movement Science & Health
Multimodal motion capture for sports, rehabilitation, ergonomics, and diagnostic support.Life Sciences & Environmental Monitoring
AI-based biological data analysis, intelligent monitoring systems, and biodiversity observation.
The group’s core strength lies in methodological excellence with strong transferability, enabling impactful applications across mobility, health, inclusion, and environmental sustainability.
