First International Workshop on Ubiquitous Human-Computer Interaction (UbiHCI 2011) encourages full papers and notes that reflect the breadth and scope of UbiHCI on Ubiquitous research, including conceptual development, empirical investigations, technological advances, user experiences, and more. All papers should clearly compare and contrast how the work relates to previous research or experience, what aspects of the work are new, and the major contributions it makes. Although it is expected that papers will focus on one or a small number of the aforementioned areas, authors should write for the broader UbiHCI audience, and make clear how the work contributes to the UbiHCI field as a whole.

We solicit original research and technical papers not published elsewhere focusing on the following topics (but not limited to):

1. Theory and Architecture

Ubiquitous and pervasive computing
Human-computer interaction in ubiquitous computing environments

Ubiquitous user-generated content
Visualization techniques for the mobile context
Group interaction and mobility
Multimodal interaction (including audio and speech)
Multi-cultural interaction
Context-aware systems
Extending awareness, contextualization and collaboration
Education about HCI
Human-work interaction design
Computer supported cooperative work
Artificial intelligence and agents
