Abstract
This century has witness a substantial increase in elderly population. Health
issues like depression and dementia are more prominent in these elderly populations
which demand Assisted Living environment. The engagement of technology is seen as
a solution for the Assisted Living environment. With the help of technology, Ambient
Assisted Living (AAL) has become a field of research. As AAL strives to seamlessly
connect information technology with people's daily lives, the buzz word called Internet
of Things (IoT) exhibits significant promise for developing technical solutions in this
field. Geo-fencing is one such location sensing tool that uses IOT and GPS for defining
geographical boundaries and is used for putting e-fences to the needy people in their
ambiances. This article aims to provide a safe tracker environment that allows the
elderly people to continue with their daily activities. In this article, application built for
elderly people is explained. Through this application, the person gets the direction to
reach back home or the alert message is sent to the family member or the caretaker.
The alert message is sent while the person is out of the fencing area to himself or to the
care takers and the location of the person can be tracked. This app can also be modified
for different users like person with disability, game like pub-G players etc. for the
situations where the device sense that the person is in a danger zone or out of the geo-fencing.
