Claudine TiercelinMétaphysique et philosophie de la connaissanceAnnée 2022-2023Colloque - Virtual and Augmented Realities: Epistemological and Metaphysical Issues : Eye Movements and the Feeling of PresenceIntervenant(s)Bence Nanay, University of AntwerpRésuméEmpirical studies show great variation in the smoothness of tracking eye movements in various perceptual situations. In this talk, I examine the relation between the smoothness of tracking eye movements and the feeling of presence in the case of perception, dreaming, visualising, stereograms and virtual reality and argue for a very minimalist and mechanistic explanation of the feeling of presence. 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
