It is our great pleasure to welcome you to The 5th ACM Workshop on Wearable Systems and Applications -- WearSys 2019. The WearSys workshop is inspired by the fact that wearables are spearheading advancements in technology through inter-disciplinary research among a broad spectrum of disciplines such as mobile health, fashion, energy, just to name a few. The 5th ACM Workshop on wearable systems and applications, WearSys 2019, is focused on how wearable technologies can shape mobile computing, systems and applications research. The goal of this workshop is to provide a forum to bring together researchers and design experts to discuss how wearable technologies have, and can, complement mobile systems research, and vice-versa. It also aims to provide a launchpad for bold and visionary ideas for wearable systems research. The call for papers attracted a number of high-quality submissions from all over the world. The program committee reviewed and accepted 10 full papers and 3 position papers. Besides these contributions, the WearSys 2019 program includes two fantastic keynotes from Prof. Steve Mann and Prof. Josiah Hester. Putting together WearSys 2019 was a team effort. We first thank the authors for providing the content of the program. We are grateful to the program committee who worked very hard in reviewing papers and providing feedback for authors. We thank the MobiSys 2019 workshop |
