Ubiquitous Computing: Defining an HCI Research - Agenda for an Emerging Interaction Paradigm

<E-213> Ubiquitous computing (ubicomp) is an emerging paradigm for interaction between people and computers. A<E-443> guiding principle of ubicomp is to break away from desktop computing to provide computational services<E-419> to a user when and where required. Although there has been a lot of experimental work in ubicomp, there<E-431> has been little effort to define an agenda in ubicomp for HCI researchers. In this paper, we attempt to<E-442> remedy that problem by defining the space of ubicomp applications in terms of the level of user mobility<E-415> and transparency of interaction. Increases in user mobility will come with technological advances, but<E-437> increased interaction transparency will come only with breakthroughs in HCI research. We conclude the<E-438> paper with a discussion of two functional themes that we have found important across a number of ubicomp<E-416> systems ---context-awareness and automated capture, integration and access. Each of these themes raises<E-..
