What are the factors determine our ability to remain focused on a task and not reorient our limEvent-related potentials to auditory notifications depending on their perceived task relevance (Scheer, Bütlhoff, Chuang, 2018)ited mental resources elsewhere? Our research uses a combination of psychophysics and psychophysiological methods to understand the mechanisms that underlie sustained attention and its interruption. In particular, we are interested in the phenomenon of ,,inattentional deafness", whereby individuals do not notice the occurrence of seemingly task-irrelevant events that may turn out to be important later on. We have investigated this phenomenon in the context of continuous motor control, allowing for generalizations to vehicle control. This line of research has implications for the design of notification displays and working practices.

The miniaturization of electronics combined with cloud computing means that we are able to outsource cognitive processes to wearable devices, such as a smartwatch that monitors our fitness levels. We research the implications of this for augmenting the native intelligence of human users across novel systems. For instance, using computer vision on smartphones to support foreign language learning.

Human-Machine Interfaces tend to be designed for uni-directional communications. Even with intuitive input In situ display system that provides just-in-time instructions to place bricks in an assembly system, which reduces mental workload.channels, such as gestures, a machine typically operates on the explicit instructions provided by human users. Our research informs the design of bi-directional interfaces that enable machines to adapt themselves to the changing requirements of human users as well as to provide human users oversight of the "reasoning" processes that underlie decision making in automated machine systems. This involves understanding how humans adapt their behavior and levels of acceptance according to the perceived reliability of machine systems as co-workers. In one project (right), we determined how just-in-time instructions for assembling an object could reduce perceived mental workload, which is reflected in EEG activity. Ongoing research is interested in ensuring that reducing mental workload does not result in boredom or task disengagement.

Advances in displays has allowed us to create synthetic experiences for our sensory modalities. Thus, our perception of physical reality can be mediated by technology and auxiliary information. This poses several challenges. First, in negotiating the smooth interactions of all actors who inhabit the same physical space. Second, in ensuring that auxiliary information complement rather than conflict with information from physical reality.  Third, in designing the presentation of auxiliary and novel information to be compatible with our sensory abilities.
