„Wie Vertrauen entsteht, in welchen Fällen wir KI-Agenten unser Vertrauen (unbewusst) schenken und wie diese Erkenntnisse das autonome Fahren unterstützen, behandelt Maximilian Wächter vom Institut für Kognitionswissenschaft in seinem Vortrag am Donnerstag, 23. September, ab 19 Uhr. Der Online-Vortrag wird im Rahmen der Veranstaltungsreihe "Wissenschaft trifft Wirtschaft - MeetUp" organisiert. Vorherige...

Neuroimage 237:118179

This paper was also published as a preprint on bioRxiv in 2020: https://doi.org/10.1101/2020.10.16.342105

09. August 2021 : A novel approach for training artificial neural networks

Clay V, König P, Kühnberger KU and Pipa G (2021).
Fast concept mapping: The emergence of human abilities in artificial neural networks when learning embodied and self-supervised.
https://arxiv.org/abs/2102.02153 arXiv:2102.02153

Science has proved that humans perceive the world and gradually understand and learn about its underlying concepts by self-supervised interaction and embodiment. By contrast, most artificial neural networks used for object detection and recognition are trained in a...

30. July 2021 : Investigating potential differences in the interaction between humans and humans vs. humans and robots

Czeszumski A, Gert AL, Keshava A, Ghadirzadeh A, Kalthoff T, Ehinger BV, Tiessen M, Björkman M, Kragic D and König P (2021)
Coordinating with a robot partner affects action monitoring related neural processing.
DOI: https://doi.org/10.1101/2021.03.26.437133
bioRxiv

Robots play an increasing role in multiple areas of our social life, and coordinated interaction between humans and robots will become more and more important.
In our study we aimed at understanding obvious behavioural differences in...

21. July 2021 : New publication on ergonomic risk assessment in VR:

Vox JP, Weber A, Wolf KI, Izdebski K, Schüler T, König P, Wallhoff F and Friemert D (2021). An evaluation of motion trackers with virtual reality sensor technology in comparison to a marker-based motion capture system based on joint angles for ergonomic risk assessment. https://doi.org/10.3390/s21093145 Sensors 21:3145

Measurement of body postures and kinematics in VR is a promising tool for ergonomic assessments. Here we compare an HTC Vive tracker combined with an inverse kinematic model...

11. June 2021 : CogSci Startup LobVR könnte die Psychotherapie revolutionieren; die Aloys & Brigitte Coppenrath Stiftung und ein EXIST Stipendium ermöglichen weiteres Wachstum im Bereich FuE

Ende 2019 hatten wir bereits über das damals noch junge Startup LobVR berichtet. Damals hatten die Gründer Sumin Kim, Imke Mayer, Alexander Palatnik, Marc Viladrich und Timon Jäger einen Platz im Seedhouse accelerator program gewonnen.

Seitdem ist viel passiert, und LobVR ist auf dem besten Wege, sich als Firma zu etablieren. Das Potential für die weitere Forschung und Entwicklung ist enorm. Und mit großzügiger finanzieller Unterstützung durch die Aloys & Brigitte Coppenrath Stiftung und ein EX...

31. May 2021 : New publication on mood primed perception of our world:

Czeszumski A, Albers F, Walter S and König P (2021). Let me make you happy, and I'll tell you how you look around: Using an approach-avoidance task as an embodied emotion prime in a free-viewing task.
https://doi.org/10.3389/fpsyg.2021.604393. Front Psychol 12:604393

Although emotional priming has been an important topic in research on top-down influences in overt attention, in particular regarding external and internal affective influences, there is little research using embodied primes.

In...

28. May 2021 : Investigating gaze guidance behavior under VR conditions

Keshava A, Nezami FN, Neumann H, Izdebski K, Schüler T and König P (2021).
Just-in-time: Gaze guidance behavior while action planning and execution in VR.
DOI: https://doi.org/10.1101/2021.01.29.428782. bioRxiv

Eye movements in the natural environment have primarily been studied for common and repetitive tasks that require little attention once learnt. It is, however, unclear whether the same strategy is also applied, when the task is novel and involving a sequence of actions.
Here, we present...

31. March 2021 : An open access toolkit for studies of traffic and automated driving in VR

Nosrat Nezami F, Wächter MA, Maleki N, Spaniol P, Kühne LM, Haas A, Pingel JM, Tiemann L, Nienhaus F, Keller L, König SU, König P and Pipa G (2021)
Westdrive X LoopAR: An open-access virtual reality project in Unity for evaluating user interaction methods during take-over requests
https://doi.org/10.3390/s21051879

With the further development of highly automated vehicles, drivers will engage in non-related tasks while being driven.
To investigate the crucial question of how...

24. March 2021 : New publication on embodied learning research. Training an agent in VR by deep reinforcement learning.

Clay V, König P, Kühnberger KU and Pipa G (2020)
Learning sparse and meaningful representations through embodiment
DOI: https://doi.org/10.1016/j.neunet.20202.11.004
Neural Netw 134:23-41

How do humans acquire a meaningful understanding of the world with little to no supervision or semantic labels provided by the environment?

To answer this question, we investigated the influence of embodiment by means of a deep reinforcement learning agent that was trained before in a 3D environment with...
