Computing systems that sense, model, and adapt to their users’ cognitive states.
In today’s information society, knowledge is created at an ever-increasing pace. As a result, most of us face constant pressure to consume information and acquire new knowledge. But information gain and learning require time and mental resources. While the proliferation of ubiquitous computing devices, such as smartphones, enables us to consume information anytime and anywhere, technologies are often disruptive rather than sensitive to the current user context.
For example, mobile applications trigger a plethora of notifications throughout the day, which often causes interruptions and breaks users’ concentration. In addition, people exhibit different levels of concentration and cognitive capacity over the course of the day. During phases of low performance, the ability to concentrate is very limited, which negatively affects the effectiveness of information intake. Mobile applications do not take these variations in performance into account and often overburden the user with information or cause boredom due to a lack of stimulation.
Cognition-aware systems sense, model, and adapt to users’ current cognitive states and systematic fluctuations, including varying states of alertness, fatigue, and general receptivity. In our research, we create tools and applications that use mobile and stationary sensors to monitor attention and reconstruct circadian rhythms of alertness and homeostasis. Technologies aware of our fluctuating cognitive capacities enable the development of interfaces that consider our attentional limitations and boost our focus and productivity.
We are actively collaborating with researchers from Osaka Prefecture University in Japan and the German Research Center for Artificial Intelligence in Kaiserslautern, Germany.
