Recent advances in medical sciences along with the declining birth rate in the developed world is projected to exacerbate the phenomenon of population aging in the coming years. This effect is expected to challenge the viability of health and welfare systems, requiring substantial public and private financial funding for the maintenance of institutions and infrastructure such as health and elderly care centers or nursing homes. It is, therefore, urgent to investigate solutions that will prolong the independent living of elderly people at home, deferring their moving to care centers as long as possible. These solutions should take into account factors that compromise the level of safe living of senior citizens. Such factors include sudden ailments and falls, which commonly cause injuries or loss of consciousness, making it impossible for elderly who live alone to call for help.
