Abstract
Mobile and wearable sensors are increasingly becoming our
everyday life in monitoring and controlling
health, well-being and security. Our work presents the
technological enablers and requirements for
building a complete end-to-end energy-efficient system
for improving and controlling safety issues for
children in day-care centers and schools. We designed a
proof-of-concept for a wearable sensor vest
with integrated wireless charging that takes place in the
ordinary repository for the vests, such as in a
wardrobe or a coat rack, without requiring any specific
actions from the user. The developed sensor vest
provides information about the location and well-being of
children, based on received signal strength
indication (RSSI), global positioning system (GPS),
accelerometer, and temperature sensors. Teachers and
parents are able to receive alerts and notifications,
e.g., when a child moves across a certain restricted
outdoor or indoor area, through gateways that have
connectivity to a server or cloud. Piloting and
technological implementations are based on a
participatory study conducted among children, teachers,
and parents, to gain important knowledge and
understanding about the real user needs and service
system usability requirements. The vest is part of a
larger framework to provide digital safety applications
and services through various sensor devices.
