  Sleep deprivation is a public health issue. Awareness of sleep deprivation
has not been widely investigated in workplace-based wellness programmes. This
study adopted a three-stage design process with nine participants from a local
manufacturing company to help raise awareness of sleep deprivation. The common
causes of sleep deprivation were identified through the deployment of
technology probes and participant interviews. The study contributes smart
Internet of things(IoT) workplace-based design concepts for activity tracking
that may aid sleep and explore ways of sharing personal sleep data within the
workplace. Through the use of co-design methods, the study also highlights
prominent privacy concerns relating to use of personal data from different
stakeholders' perspectives, including the unexpected use of sleep data by
organisations for fatigue risk management and the evaluation of employee
performance. The Actigrahy and sleep diary data can be accessed online through
