Proceedings of the 1st Workshop on Large-scale and Model-based Interactive Systems: Approaches and Challenges (LMIS 2015)

Pervasive and ubiquitous computing introduce a new quality of interaction both into our lives and into software engineering. This has led into an unprecedented interest in implying the full potential of the human body’s sensory and motor systems for multi-modal interactivity, manifested by new market initiatives for motion gestures, brain-computer interfaces, multi-touch devices, etc. Whilst this new Post-WIMP interaction paradigm provides rich interaction possibilities and fertile ground for innovation, its increasing popularity imposes new critical challenges for the adoption of interaction techniques in realworld ambient spaces. Software becomes increasingly dynamic, requiring frequent changes to system structures, distribution and behaviour. The aforementioned needs and challenges are mainly caused by increased user mobility, increased heterogeneity of available interaction resources, and increased diversity of physical abilities (i.e., diversity of user population). This workshop discusses various approaches to handle these challenges to support flexible, context-aware and interactive spaces. We put special focus on promising approaches for coping with dynamics and uncertainties inherent to interactive ubiquitous systems, particularly model-based interaction at runtime and large-scale interaction ensembles (i.e., combining and adapting multiple interactions at runtime). The workshop was held as a full day workshop and aimed to provide a forum for discussing new ideas, issues and approaches. It included a keynote speech, presentation of participants’ contributions and various forms of interactive discussions concerning the presented topics.
