In this paper, we introduce a virtual reality system which can elicit causal perception. ...
We present results from a user experiment, which confirm a high level of causal perception in subjects having used the system. ...

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. ...

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. ...

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 ...

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 . ...

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. ...
