  abstract  = {Plenty of theories, models, measures, and investigations target the understanding of virtual presence, i.e., the sense of presence in immersive Virtual Reality (VR). Other varieties of the so-called eXtended Realities (XR), e.g., Augmented and Mixed Reality (AR and MR) incorporate immersive features to a lesser degree and continuously combine spatial cues from the real physical space and the simulated virtual space. This blurred separation questions the applicability of the accumulated knowledge about the similarities of virtual presence and presence occurring in other varieties of XR, and corresponding outcomes. The present work bridges this gap by analyzing the construct of presence in mixed realities (MR). To achieve this, the following presents (1) a short review of definitions, dimensions, and measurements of presence in VR, and (2) the state of the art views on MR. Additionally, we (3) derived a working definition of MR, extending the Milgram continuum. This definition is based on entities reaching from real to virtual manifestations at one time point. Entities possess different degrees of referential power, determining the selection of the frame of reference. Furthermore, we (4) identified three research desiderata, including research questions about the frame of reference, the corresponding dimension of transportation, and the dimension of realism in MR. Mainly the relationship between the main aspects of virtual presence of immersive VR, i.e., the place-illusion, and the plausibility-illusion, and of the referential power of MR entities are discussed regarding the concept, measures, and design of presence in MR. Finally, (5) we suggested an experimental setup to reveal the research heuristic behind experiments investigating presence in MR. The present work contributes to the theories and the meaning of and approaches to simulate and measure presence in MR. We hypothesize that research about essential underlying factors determining user experience (UX) in MR simulations and experiences is still in its infancy and hopes this article provides an encouraging starting point to tackle related questions.},

  abstract  = {We are witnessing a return of the real which philosophy seems illequipped to handle. I argue (1) that this return of the real must be read as a rejection of those philosophical tendencies which were prevalent in the past decades and which I call philosophies of mediation: They supplanted all references to something real by the sole reference to those processes in which reality was supposed to be given or shaped (in interpretations, linguistic structures, historical or social conditions, media…). The current urgency of the question of the real indicates that those philosophies have lost credibility. On the other hand (2), the contemporary attempts to resuscitate philosophical realism cannot be considered satisfactory either. It is curiously the real itself they fail to fully appreciate. All in all (3), the return of the real has to be interpreted as the effect of an event that has little to do with philosophy, namely the return of politics.},
