Abstract
From the past few decades entire world is witnessing the phenomenon of population ageing as a result of life longevity and declining birth rate of modern society. India is also not immune to this demographic change and will have major socio-economic consequences over the period of time. Information and Communication Technologies (ICT) will make the targeted interventions to provide assistance to the older adults to improve their quality of life, stay healthier and live independently for a time. Active and Assisted Living (AAL) is one such innovative targeted technology to provide quality healthcare and rehabilitation services to the impaired seniors. In this paper we present comprehensive survey to monitor the recent trends in the realm of AAL. First we discuss about the generic overview of AAL and Ambient Intelligence (AmI). Next, we highlight the relevance of enabling technologies for AAL. Then we review the various trending scenarios of AAL and major research projects being carried out across the world. Finally, we conclude by proposing some possible directions for the future work in the area of AAL.
Highlights
According to WHO reports [3], developing countries are witnessing the variation in the pattern of their population attaining the older age structures with number of people aged 65 or older is projected to grow from an estimated 524 million in 2010 to approximately around 1.5 billion in 2050
2) Activity recognition based on ambient sensors Even though wearable sensor based approaches can obtain satisfactory performance, it is difficult for them to be widely applied in AAL environment because this kind of method requires users to wear or carry corresponding sensors all the time which may intrusive in nature while performing the daily activities and in some scenarios system may encounter with the task of recognizing the complex activities which may involve group of individuals engaged together to accomplish some task
In prevailing scenario there is no free flow or exchange of data among the heterogeneous entities which has constrained our efforts in expanding the horizon of AAL solutions and has led to the creation of data silos
Summary
The dwindling birth and mortality rate among the human population has led to the global phenomenon of population ageing This demographic transition will be more severe and will have a consequential impact on our society in years to come. According to WHO reports [3], developing countries are witnessing the variation in the pattern of their population attaining the older age structures with number of people aged 65 or older is projected to grow from an estimated 524 million in 2010 to approximately around 1.5 billion in 2050. As per the demographic reports [4] , there are nearly 104 million people aged 60 or above in India which comprises the 8.6% of total population which has increased over time from 5.6% in 1961 and it is projected that aged population will grow to 20% (i.e. around 324 million)by 2050.
