research mission

Developing human-machine systems that fully exploit the information content available in non-verbal human behaviour is challenging, particularly in unconstrained daily life settings. Key challenges are 1) to develop sensing systems that robustly and accurately capture non-verbal human behaviour in these settings, 2) to develop computational methods for automatic analysis and modelling that cope with the variability and subtleness in human behaviour, and 3) to develop novel human-machine systems that exploit non-verbal behavioural cues to enable collaborative or even symbiotic interactions. To this end, our group works at the interface of ubiquitous computing, human-computer interaction, computer vision, and machine learning. We develop novel computational methods as well as ambient and on-body systems to sense non-verbal human behaviour. We specifically focus on visual and physical behaviour as well as brain activity as these modalities are most promising for developing interfaces that offer human-like perceptual and interactive capabilities.
