Welcome Message from the General Chairs

Thanks to the ubiquity of smart devices, wearables, and IoT devices, users are adopting the trend of using more than one device at the time to support their activities in everyday live. Despite multiple devices being carried by users and being available on their vicinity, devices operate in a very isolated manner. Indeed, devices have a limited view of their surrounding, and struggle to operate continuously in the wild due to their constrained resources.

Transforming the view of a device from a single egocentric one, to a collaborative multi-device view is of high relevance for releasing devices from resource constrained limitations and improving the perception of users through better quality of service and experience. The importance of multi-device computing can be envisioned in many applications in everyday settings, for which they were not initially conceived, such as continuous and adaptive multi-device interfaces for users, formation of proximal multi-device computing infrastructure at the Edge network, multi-device remote control systems, multi-device sensing data fusion and multi-device autonomous interactions, among others.

However, self-organization of devices into multi-device schemes for collaboration is far from straightforward as it requires a deep understanding on the context of each device. Indeed, context of a device is understood to depict the characteristics of its resources as well as its runtime configuration in the wild. Thus, understanding the multi-device context is critical to engage into device to device collaborations. The goal of the 2nd IEEE International Workshop on Context-Awareness for Multi-Device Pervasive and Mobile Computing (PerCrowd 2019) is to provide a forum that brings together researchers from academia as well as practitioners from industry, standardisation bodies and governments to meet and exchange ideas on recent and future directions for multi-device systems and applications.

In this second year, PerCrowd includes 1 keynote talk, a panel discussion with experts on the field as well as 8 papers on topics of multi-device sensing, computing and interfaces. Papers to be presented in the workshop have been rigorously reviewed and carefully selected based on their relevance, technical depth and novelty by an international technical programme committee. We are very grateful to the technical programme committee for their hard work, and we would also like to thank all the authors for choosing PerCrowd as an avenue to present their work.

Welcome to PerCrowd 2019!

We hope you'll enjoy the workshop.
