Framing the context of use for Mobile HcI

The need to better understand the role of context has emerged after the revolution of mobile computing, as such devices are used in heterogeneous circumstances. However, it is difficult to say what context of use in mobile human-computer interaction actually means. This study summarises past research in mobile contexts of use and not only provides a deeper understanding of the characteristics associated with it, but also indicates a path for future research. This article presents an extensive and systematic literature review of more than 100 papers published in five high-quality journals and one main conference in the field of HCI during the years 2000-2007. The authors' results show that context of use is still explored as a relatively static phenomenon in mobile HCI. Its most commonly mentioned characteristics are linked to social, physical, and technical components, while transitions between the contexts were rarely listed. Based on this review, a descriptive model of context of use for mobile HCI (CoU-HMCI) summarising five components, their subcomponents and descriptive properties is presented. The model can help both practitioners and academics to identify broadly relevant contextual factors when designing, experimenting with, and evaluating, mobile contexts of use.
