Evolution in IT has resulted in significant changes
in our everyday life. Information has become ubiquitous,
can be accessed almost anywhere and anytime
and be leveraged to deal with our tasks more efficiently.
Moreover, we now have access to new kinds
of information previously unavailable. One such kind
of information that can have a major impact is an
overview of our everyday physical activity. Having
this information is a basic prerequisite if we want to
tackle one of the biggest problems of our society – the
lack of physical activity, overweight and obesity.
This information can be captured and interpreted
by an intelligent wearable device. However, the requirement
to wear an additional measuring device is a
key barrier to achieving long-term sustainability (Fujiki,
2008). It is therefore preferable to rely on a device
people already carry, i.e. a smartphone.
Currently available solutions track users’ movement
“on-demand”, mainly using GPS sensors. However,
they are mainly used by already rather physically
active people, while most of the people who
need to become more physically active are unaware
of such solutions or are not motivated to use them
as they do not exercise regularly. We focus on such
people who require additional motivation in order to
become more physically active.
