Human Perception, Cognition & Action
The World in our Heads
The department is concerned with the fundamental processes of human perception. The primary focus is how the information from different sense organs is integrated to create a consistent representation of the “world in our heads”.
Traditional psychophysics methods are combined with the most up-to-date computer graphics and Virtual Reality systems to understand the “algorithms of perception”. Psychophysics addresses the mathematical description of associations between physical stimuli and the perceptions they trigger in humans. The use of computer simulations and realistic virtual environments to carry out psychophysical experiments maximizes the possibility of dynamic feedback and interactivity. At the same time, this approach allows complete control over all the aspects of the simulation to reach accurate conclusions about human perception.
The research focuses on the integration of information from the visual, haptic and balance senses and on the development of efficient algorithms for building assistant systems to help the aging society to cope with the challenges of the decline with age in perceptual and cognitive capabilities.

Former Research groups
We investigate how humans process information, relevant for the effective control of machine systems, such as vehicles. Machines extend our physical capacity to sense and interact with our environments. For example, collision avoidance systems in an aircraft allow the pilot to be aware of fast moving traffic before they are even within range of human sight. Meanwhile, the pilot selectively relies on information provided by the system, to determine and execute the appropriate combination of actions, necessary for effectively maneuvering of the aircraft.
Interaction with the social and spatial environment are fundamental components of daily life. Previous research mainly examined both domains separately. However, social and spatial processes interact. For example, joint actions happen within space and social factors such as personal distance are expressed spatially. The goal of this group is to examine social and spatial cognition and importantly the relation between both. Specifically, we investigate representations underlying navigation, action perception and execution, and the representational overlap between human bodies, social properties, and space.
We aim to study novel algorithm for autonomous machines (robots) that are able to sense the environment, reason about it, and take actions to perform tasks in cooperation with humans. The driving vision behind our research is to allow in the future robots to aid humans, for example to reduce physical effort and risks in industrial environment, help prevention and reaction in emergency situations as natural disasters, and in general simplify tasks of everyday life.
The Cognitive Engineering group developed applications based on Computer-Vision, Computer-Graphics and Machine-Learning in combination with methods that analyse Human cognitive processes.
In this research group, the aim was to investigate human behavior, perception and cognition using ecologically valid and immersive virtual environments.
