In this chapter we will discuss the concepts of “presence” (Inner Presence) and “social presence” (Co-presence) within a cognitive and ecological perspective. Specifically, we claim that the concepts of “presence” and “social presence” are the possible links between self, action, communication and culture. In the first section we will provide a capsule view of Heidegger’s work by examining the two main features of the Heideggerian concept of “being”: spatiality and “being with”. We argue that different visions from social and cognitive (...) sciences – Situated Cognition, Embodied Cognition, Enactive Approach, Situated Simulation, Covert Imitation - and discoveries from neuroscience – Mirror and Canonical Neurons - have many contact points with this view. In particular, these data suggest that our conceptual system dynamically produces contextualized representations (simulations) that support grounded action in different situations. This is allowed by a common coding – the motor code – shared by perception, action and concepts. This common coding also allows the subject for natively recognizing actions done by other selves within the phenomenological contents. In this picture we argue that the role of presence and social presence is to allow the process of self-identification through the separation between “self” and “other,” and between “internal” and “external”. Finally, implications of this position for communication and media studies are discussed by way of conclusion. (shrink)

This thesis discusses the potential consequences of applying the philosophy of Mark C. Taylor to the field of Human-Computer Interaction. The first part of the thesis comprises a study focusing on two discursive trends in contemporary HCI, materiality and the self, and how these discourses describe interaction. Through a qualitative, inductive content analysis of 171 HCI research articles, a number of themes are identified in the literature and, it is argued, construct a dominant perspective of materiality, the self, and interaction. (...) Examples that differ from the dominant discourse are also discussed as alternative perspectives for each of the three focal areas. The second part of the thesis comprises an analysis of Mark C. Taylor’s philosophical project which enables a number of philosophical positions on materiality, the self, and interaction to be identified. These positions are suggested to be variations and rereadings of themes found in Friedrich Nietzsche’s philosophy. These variations emerge as Taylor approaches Nietzsche through poststructuralism and complexity theory, and it is argued that the apparent heterogeneity of Taylor’s project can be understood as a more coherent position when interpreted in relation to Nietzsche’s philosophy. Based on the findings of the two literature studies, the thesis then discusses the possible consequences for HCI, if Taylor’s philosophy were to be applied as a theoretical framework. The thesis argues that Taylor’s philosophy describes the interaction between humans and computers as an existential process, which contrasts with the dominant HCI discourse; that this view can be related to and provide a theoretical foundation for the alternative discourses in HCI; and that it can contribute to developing HCI.
