What is the Avatar? Fiction and Embodiment in Avatar-Based Singleplayer Computer Games: Revised and Commented Edition

What are the characteristic features of avatar-based singleplayer videogames, from Super Mario Bros. to Grand Theft Auto? The author examines this question with a particular focus on issues of fictionality and realism, and their relation to cinema and Virtual Reality. Through close-up analysis and philosophical discussion, the author argues that avatar-based gaming is a distinctive and dominant form of virtual self-embodiment in digital culture. This book is a revised edition of Rune Klevjer's pioneering work from 2007, featuring a new introduction by the author and afterword by Stephan Günzel, Jörg Sternagel, and Dieter Mersch

A Seeing Place – Connecting Physical and Virtual Spaces

In the experience and design of spaces today, we meet both reality and virtuality. But how is the relation between real and virtual construed? How can we as researchers and designers contribute to resolving the physical-virtual divide regarding spaces? This thesis explores the relations between the physical and the virtual and investigates ways of connecting physical and virtual space, both in theory and practice.\ua0The basic concepts of the thesis are Space, Place, and Stage. The central idea is that the stage is a strong conceptual metaphor that has the capacity to work as a unifying concept relating physical and virtual spaces and forming a place for attention, agreements, and experience – A Seeing Place. The concept of seeing place comes from the Greek word theatre, meaning a “place for seeing”, both in the sense of looking at and understanding.\ua0In certain situations, the relations between physical and virtual spaces become important for users’ experience and understanding of these situations. This thesis presents seven cases of physical-virtual spaces, in the field of architectural and exhibition design. The method of these studies is research by design. The discussion then focuses on how each setting works as a stage, and how conceptual metaphors can contribute to the connection between physical and virtual spaces.\ua0Building upon the explorations and experiments in different domains, the thesis contains a collection of seven papers concerning the relations between physical and virtual space in different contexts outside the world of theatre. These papers range from more technical about Virtual Reality (design of networked collaborative spaces) to more conceptual about staging (methods in interaction design) and virtual space (using a transdisciplinary approach).\ua0The results of those studies suggest that the Stage metaphor of a physical-virtual space can contribute to the elucidating of relations between physical and virtual spaces in number of ways. Conceptually, the stage metaphor links together the semiotic and the hermeneutic views of space and place. And, from a practice-based perspective, A Seeing Place view opens up the way to creating contemporary spaces and resolving the physical-virtual divide

Plasticity and neuromodulation of the extended recurrent visual network

The extended visual network, which includes occipital, temporal and parietal posterior cortices, is a system characterized by an intrinsic connectivity consisting of bidirectional projections. This network is composed of feedforward and feedback projections, some hierarchically arranged and others bypassing intermediate areas, allowing direct communication across early and late stages of processing. Notably, the early visual cortex (EVC) receives considerably more feedback and lateral inputs than feedforward thalamic afferents, placing it at the receiving end of a complex cortical processing cascade, rather than just being the entrance stage of cortical processing of retinal input. The critical role of back-projections to visual cortices has been related to perceptual awareness, amplification of neural activity in lower order areas and improvement of stimulus processing. Recently, significant results have shown behavioural evidence suggesting the importance of reentrant projections in the human visual system, and demonstrated the feasibility of inducing their reversible modulation through a transcranial magnetic stimulation (TMS) paradigm named cortico-cortical paired associative stimulation (ccPAS). Here, a novel research line for the study of recurrent connectivity and its plasticity in the perceptual domain was put forward. In the present thesis, we used ccPAS with the aim of empowering the synaptic efficacy, and thus the connectivity, between the nodes of the visuocognitive system to evaluate the impact on behaviour. We focused on driving plasticity in specific networks entailing the elaboration of relevant social features of human faces (Chapters I & II), alongside the investigation of targeted pathways of sensory decisions (Chapter III). This allowed us to characterize perceptual outcomes which endorse the prominent role of the EVC in visual awareness, fulfilled by the activity of back-projections originating from distributed functional nodes
