Ubiquitous Interaction studies the design, development and evaluation of interactivity with users in ubiquitous and mobile computing systems. The research is carried out coupling in-depth user studies with design in the area of novel interfaces. The goal is to contribute to technology development efforts by deepening understanding of human and design perspectives. Currently, research is conducted in different areas: multitouch displays, adaptivite and affective interfaces, multimodal interaction, exploratory search and social computing. Application areas range from sustainability and environmental awareness, home computing, walk-up-and-use display, information exploration, art and culture, scientific and knowledge work.
