In this talk, I argue that this is not the most obvious way, and I oppose it with a (pseudo-)dualistic conception of VR, combining reality and fiction. To do this, I will draw on Walton's analysis of fictions and on Wollheim's conception of what it is to see-in a pictorial work. It seems that we can understand our interactions in virtual worlds not as a radical rupture, but as an extension of our usual ways of seeing object representations. The proposed conception taking its start in a logical analysis of the statements produced during our interactions in virtual worlds, it also relies on a formal background, based on an extension of first-order modal logic, which will be briefly evoked.PrésentationVirtual Reality technology affords its users a strongly immersive and interactive experience of computer-generated environments, through a dedicated headset. With Augmented Reality devices, 3D computer-generated imagery is projected onto physical space, thereby "augmenting" the user's surroundings with an overlay of virtual entities. These "Extended Reality" (XR) technologies are likely to become a part of our everyday life in the near future. They also raise a host of fascinating issues, which have increasingly been discussed in the recent philosophical literature. This international conference will investigate the metaphysical and epistemological questions raised by XR technologies.Le colloque est intégralement en anglais et a eu lieu les 5 et 6 juin au Collège de France
