Bridging e-Health and the Internet of Things: The SPHERE Project
Ni Zhu,Tom Diethe,Massimo Camplani,Lili Tao,Alison Burrows,Niall Twomey,Dritan Kaleshi,Majid Mirmehdi,Peter A. Flach,Ian J Craddock +9 more
TL;DR: An overview of this rapidly growing body of work on sensing systems in the home, as well as the implications for machine learning are presented, with an aim of uncovering the gap between the state of the art and the broad needs of healthcare services in ambient assisted living.
Journal ArticleDOI
A Comprehensive Study of Activity Recognition using Accelerometers
Niall Twomey,Tom Diethe,Xenofon Fafoutis,Atis Elsts,Ryan McConville,Peter A. Flach,Ian J Craddock +6 more
TL;DR: This paper serves as a survey and empirical evaluation of the state-of-the-art in activity recognition methods using accelerometers, particularly focused on long-term activity recognition in real-world settings.
Book ChapterDOI
SPHERE: A sensor platform for healthcare in a residential environment
Pete Woznowski,Alison Burrows,Tom Diethe,Xenofon Fafoutis,Jake Hall,Sion Hannuna,Massimo Camplani,Niall Twomey,Michal Kozlowski,Bo Tan,Ni Zhu,Atis Elsts,Antonis Vafeas,Adeline Paiement,Lili Tao,Majid Mirmehdi,Tilo Burghardt,Dima Damen,Peter A. Flach,Robert J. Piechocki,Ian J Craddock,George Oikonomou +21 more
TL;DR: The home possesses unique characteristics that must be considered in order to develop effective smart home systems that are adopted in the real world and broadly underpinned by shared goals of sustainable development, inclusive user engagement and improved service delivery.

The SPHERE Challenge Activity Recognition with Multimodal Sensor Data
Niall Twomey,Tom Diethe,Meelis Kull,Hao Song,Massimo Camplani,Sion Hannuna,Xenofon Fafoutis,Ni Zhu,Pete Woznowski,Peter A. Flach,Ian J Craddock +10 more
TL;DR: The SPHERE challenge is an activity recognition competition where predictions are made from video, accelerometer and environmental sensors and prizes will be awarded to the top three entrants.
Journal ArticleDOI
Unsupervised learning of sensor topologies for improving activity recognition in smart environments
TL;DR: The hypothesis is that learning patterns based on combinations of sensors will be more powerful than single sensors alone and this work shows that through the application of signal processing and information-theoretic techniques it can achieve classification performance better than that of the exhaustive approach, whilst only incurring a small cost in terms of computational resources.
