Research Interests

  • Brain-Machine Interfaces
  • Human-Robot Interaction
  • Brain State Decoding

I am interested in decoding users' brain states in human-robot interaction scenarios and utilize this information to adapt and improve robots. The user should be able to influence both what the robot does and how these actions are performed. The use of brain signals from electroencephalography (EEG) introduces a feedback modality that is non-intrusive and can also be used by impaired users who have problems communicating through other channels.

In order to control the robot, our work on screen-free object selection using brain signals introduces a novel intuitive way to communicate user intent using in-the-scene highlighting of candidates. While this online setup avoids the need for screen-based interfaces as an indirection step, the object-specific differences in signal distributions pose an interesting challenge from a machine learning perspective.

In pursuance of human-compliant robots, the user's judgment of the environment as well as the robot's actions is critical for improving robotic policies. In the context of autonomous driving, our work on decoding the perceived hazardousness in traffic scenarios from EEG offers a step towards augmenting traditional scene perception with high-level human feedback. Considering robotic assistants in manipulation tasks, EEG-based feedback can be utilized to infer trajectory preferences of the user.
