TL;DR: It is indicated that on-device sensor and sensor handling heterogeneities impair HAR performances significantly and a novel clustering-based mitigation technique suitable for large-scale deployment of HAR is proposed, where heterogeneity of devices and their usage scenarios are intrinsic.

TL;DR: Analysis methods to extract knowledge from large sets of network collected WiFi traces to better inform facility management and planning in large building complexes and spatio-temporal visualization tools built on top of these methods enable planners to inspect and explore extracted information to inform facility-planning activities.

TL;DR: This work analyzes and proposes several techniques to improve the robustness of a Human Activity Recognition (HAR) system that uses accelerometer signals from different smartwatches and smartphones.

TL;DR: A set of cross-boundary (spatial and organizational) information-sharing breakdowns and the challenges of orderlies in maintaining local and global coordination are highlighted and design recommendations for future design of coordination tools to support orderlies' work practices are presented.
