IM HERE: Interaction Model for Human Effort Based Robot Engagement
Dominykas Strazdas, Magnus Jung, Jan Marquenie +2
The effectiveness of human-robot interaction often hinges on the ability to cultivate engagement - a dynamic process of cognitive involvement that supports meaningful exchanges. Ma…
NITEC: Versatile Hand-Annotated Eye Contact Dataset for Ego-Vision Interaction
Thorsten Hempel, Magnus Jung, Ahmed A. Abdelrahman +1
Eye contact is a crucial non-verbal interaction modality and plays an important role in our everyday social life. While humans are very sensitive to eye contact, the capabilities o…
Towards Robust and Unconstrained Full Range of Rotation Head Pose Estimation
Thorsten Hempel, Ahmed A. Abdelrahman, Ayoub Al-Hamadi
Estimating the head pose of a person is a crucial problem for numerous applications that is yet mainly addressed as a subtask of frontal pose prediction. We present a novel method…
Automated Deception Detection from Videos: Using End-to-End Learning Based High-Level Features and Classification Approaches
Laslo Dinges, Marc-André Fiedler, Ayoub Al-Hamadi +4
Deception detection is an interdisciplinary field attracting researchers from psychology, criminology, computer science, and economics. We propose a multimodal approach combining d…
Sentiment-based Engagement Strategies for intuitive Human-Robot Interaction
Thorsten Hempel, Laslo Dinges, Ayoub Al-Hamadi
Emotion expressions serve as important communicative signals and are crucial cues in intuitive interactions between humans. Hence, it is essential to include these fundamentals in…
Semantic-Aware Environment Perception for Mobile Human-Robot Interaction
