Human cognition as a foundation for the emerging egocentric interaction paradigm

Abstract

This chapter presents an "egocentric interaction paradigm" (EIP) centered on human agents rather than on the notion of user. More specifically, this paradigm is based on perception, action, intention and attention capabilities and limitations of human agents. Traditional and emerging interaction paradigms are typically related to a specific computing environment, devices or human capabilities. The novelty of the proposed approach stems from aiming at developing a comprehensive and integrated theoretical approach, centered on individual human agent. Development in Human-Computer Interaction (HCI) has been closely related to the understanding and utilization of natural human skills and abilities. This work attempts to understand and model a human agent, and in particular their cognitive capabilities in facilitating HCI. The EIP is based on principles like situatedness and embodiment, the physical-virtual equity principle, and the proximity principle. A situative space model built upon our understanding of human cognition is described in detail, followed by our experience in exploring the egocentric interaction paradigm in the easy ADL home. © 2012 Springer Berlin Heidelberg.
