The concept of presence can be understood as a synthesis of interrelated psychophysical ingredients where multiple
perceptual dimensions intervene. A better understanding on how specific aspects, such as plausibility (the illusion that
virtual events are really happening), co-presence (the illusion of being with others), or place illusion (the feeling of being
there) impact XR experiences is key to improve their quality. The availability and performance of current technologies
do not reach high levels of presence in XR, which is essential to get us closer than ever to the perennial VR dream:
to be anywhere, doing anything, together with others, from any place. PRESENCE will impact multiple dimensions of
presence in physical-digital worlds, addressing three main challenges: i) how to create realistic visual interactions among
remote humans, delivering high-end holoportation based on live volumetric capturing, compression and optimization
techniques, under heterogeneous computation and network conditions; ii) how to provide realistic touch among remote
users and synthetic objects, developing novel haptic systems and enabling spatial multi device synchronisation in multi
user scenarios; iii) how to produce realistic social interactions among avatars and agents, generating AI virtual humans,
representing actual users or AI agents. PRESENCE will ensure the future uptake of research results following a threefold
evaluation method: 1) each technology will be independently evaluated to understand its impact on the illusion of
presence; 2) each component will be evaluated by the integration team, providing scientific and technical feedback in
order to facilitate their use in each project iteration as well as beyond the project scope, towards technology transfer
and exploitation; 3) all components will be integrated in two demonstrators (professional and social setups), following
a human-centred design approach and ultimately evaluating the user experience.
