Causal Perception in Virtual Reality and its Implications for Presence Factors

Marc Cavazza, Jean-Luc Lugrin, Marc Buehner
2007 Presence - Teleoperators and Virtual Environments  
In this paper, we describe the development of a virtual environment supporting experiments with causal perception.  ...  Yet, while many psychological phenomena have been studied in their relation to virtual reality (VR), very little work has been dedicated specifically to causal perception, despite its potential relevance  ...  Acknowledgments This work has been funded in part by the European Commission, through the ALTERNE Project (IST-38575).  ...

Causality and virtual reality art

Marc Cavazza, Jean-Luc Lugrin, Sean Crooks, Alok Nandi, Mark Palmer, Marc Le Renard
2005 Proceedings of the 5th conference on Creativity & cognition - C&C '05  
We have developed a VR platform using cognitive data on causal perception to create artificial event co-occurrences in virtual worlds, which can be perceived as possible outcomes for user actions.  ...  We describe the technical approach behind the elicitation of causal perception in virtual reality, and illustrate its use through the two artistic installations being developed with this new VR platform  ...  Marc Buehner is thanked for his advice on psychological aspects of causal perception. Jeffrey Jacobson is thanked for his help in porting CaveUT™ to the SAS Cube™.  ...

Pedestrian In The Loop: An Approach Using Virtual Reality

Michael Hartmann, Marco Viehweger, Wim Desmet, Michael Stolz, Daniel Watzenig
2017 Zenodo  
It is proposed to use Virtual Reality techniques. This method can be seen as a new Pedestrian in the Loop testing procedure.  ...  Examples are the change of pedestrian behaviour caused by interaction, environmental influences and personal aspects, which cannot be tested in real environments.  ...  In complex situations there are a lot more concepts necessary for safety of autonomous vehicles in environments with pedestrians. Urban environments have a very complex causal structure.  ...

The Virtual and the Real

David J. Chalmers
2017 Disputatio  
I also argue that perception in virtual reality need not be illusory, and that life in virtual worlds can have roughly the same sort of value as life in non-virtual worlds.  ...  In particular, I argue for virtual digitalism, on which virtual objects are real digital objects, and against virtual fictionalism, on which virtual objects are fictional objects.  ...  In some cases of hallucination, there is a causal basis for the perception: for example, a chair in the environment might trigger an auditory hallucination of a voice, but one does not hear the chair.  ...

New ways of worldmaking

Marc Cavazza, Jean-Luc Lugrin, Simon Hartley, Paolo Libardi, Matthew J. Barnes, Mikael Le Bras, Marc Le Renard, Louis Bec, Alok Nandi
2004 Proceedings of the 12th annual ACM international conference on Multimedia - MULTIMEDIA '04  
Besides the redefinition of physical laws, we have developed mechanisms for eliciting causal relations between events, as causality plays an important part in users' perception of virtual worlds.  ...  To implement this concept of "Alternative Reality", we have used Artificial Intelligence techniques to support the definition of the virtual environment behaviour, an approach inspired by Qualitative Reasoning  ...  Jeffrey Jacobson developed the original CaveUT2003™ system and is thanked for his assistance in adapting it to the SAS-Cube™.  ...

A deep active inference model of the rubber-hand illusion [article]

Thomas Rood and Marcel van Gerven and Pablo Lanillos
2020 arXiv   pre-print
Here, we describe a deep active inference agent in a virtual environment, which we subjected to the RHI, that is able to account for these results.  ...  Understanding how perception and action deal with sensorimotor conflicts, such as the rubber-hand illusion (RHI), is essential to understand how the body adapts to uncertain situations.  ...  Experimental setup We modelled the RHI in a virtual environment created in Unity, as depicted in Fig. 2 .  ...

Critical causal order of events in distributed virtual environments

Suiping Zhou, Wentong Cai, Stephen J. Turner, Bu-Sung Lee, Junhu Wei
2007 ACM Transactions on Multimedia Computing, Communications, and Applications (TOMCCAP)  
We investigate the causal order of events in distributed virtual environments (DVEs). We first define the critical causal order relation among the events.  ...  Experimental results show that the middleware performs well in reducing the critical causality violations in simulation and incurs little processing overhead.  ...  One important issue in DVEs is causality. As a fundamental concept, causality plays an important role in people's perception and knowledge of their living environment and the world.  ...

Intelligent virtual environments for virtual reality art

Marc Cavazza, Jean-Luc Lugrin, Simon Hartley, Marc Le Renard, Alok Nandi, Jeffrey Jacobson, Sean Crooks
2005 Computers & graphics  
We illustrate this research through the development of a fully implemented artistic brief which explores the notion of causality in a virtual environment.  ...  After describing the hardware architecture supporting immersive visualisation we show how causality can be redefined using Artificial Intelligence technologies inspired from action representation in planning  ...  Acknowledgements This research has been funded in part by the European Commission through the ALTERNE project, IST-38575.  ...

Integrating pedagogical capabilities in a virtual environment agent

Jeff Rickel, W. Lewis Johnson
1997 Proceedings of the first international conference on Autonomous agents - AGENTS '97  
Virtual environments are a promising milieu for education and training, because they allow students to practice their skills in 3D simulations of work settings.  ...  Steve employs a combination of intelligent capabilities in his interactions with students and the environment: plan revision and execution, explanation, and student monitoring.  ...  Autonomous, virtual agents can play several valuable roles in these virtual environments.  ...

Embodied Presence in Virtual Environments [chapter]

Thomas Schubert, Frank Friedmann, Holger Regenbrecht
1999 Visual Representations and Interpretations  
Presence, the sense of being in a virtual environment (VE), is analysed in an embodied cognition framework.  ...  A path analysis shows that spatial presence is mostly determined by sources of meshed patterns of actions: interaction with the VE, understanding of dynamics, and perception of dramatic meaning.  ...  The role of psycholog y in virtual environments When we use virtual environments (VEs), we often experience presence, the subjective sense of being in the virtual place.  ...

, which cannot be distinguished from veridical perception, or a virtual reality as in the film Matrix (1999).  ...  Yet, it will be argued in this paper that the interaction between the subject and the environment forms a system of causal relations, so we can theoretically interfere in the causal chains and create hallucinations  ...  If we take for granted that this is a system of causal relations, we could theoretically interfere in the causal chains and create a virtual reality as in the film The Matrix (1999) or hallucinations which  ...

The sense of body ownership relaxes temporal constraints for multisensory integration

Antonella Maselli, Konstantina Kilteni, Joan López-Moliner, Mel Slater
2016 Scientific Reports  
Crucially, the temporal window for visuotactile integration was positively correlated with participants' scores rating the illusory experience of owning the virtual body and touching the object seen in  ...  This work highlighted how own-body perception relies on a plastic brain representation emerging from multisensory integration.  ...  The influence of causal binding on temporal aspects of multisensory perception has been previously reported.  ...
