Heterogeneity of Event-Related Potentials in a Screen-Free Brain-Computer Interface

Interacting with the environment using a brain-computer interface involves mapping a decoded user command to a desired real-world action, which is typically achieved using screen-based user interfaces. This indirection can increase cognitive workload …

Influence of User Tasks on EEG-Based Classification Performance in a Hazard Detection Paradigm

Attention-based brain-computer interface (BCI) paradigms offer a way to exert control, but also to provide insight into a user's perception and judgment of the environment. For a sufficient classification performance, user engagement and motivation …

Mining Within-Trial Oscillatory Brain Dynamics to Address the Variability of Optimized Spatial Filters

Data-driven spatial filtering algorithms optimize scores, such as the contrast between two conditions to extract oscillatory brain signal components. Most machine learning approaches for the filter estimation, however, disregard within-trial temporal …

Guess What I Attend: Interface-Free Object Selection Using Brain Signals

Interpreting the brain activity to identify user goals or to ground a robot's hypotheses about them is a promising direction for non-intrusive and intuitive communication. Such a capability can be of particular relevance in the context of human-robot …
