A.1 Accelerometers

In the last decade, the usage of accelerometers for elderly people has been very successful. Elderly people are expected to live longer and they have a choice to live at the place they prefer, while ensured a high quality of life, autonomy and security as well as simultaneously reducing their expenditures on in-patient care, which will have tremendous impacts in the very near future. This also includes assistance to carry out daily activities enhancing safety and security as well as getting access to social, medical and emergency systems. Receiving social and medical support in various innovative ways contributes to independent living and quality of life for many elderly and disabled people. All this can be summarised in the Ambient Assisted Living (AAL), being monitored as a patient for any vital signs of difficulty can be gathered which consequently can help and supervise from clinical data, such as health status, falling risk and, of course, the efficiency of rehabilitation. To this effect we look at (Dinh et al., 2009) new design work. They consider using accelerometers and sensors for medical applications. Those sensors have significant advantages, for example when used with micro- electro-mechanical system (MEMS) accelerometers one can monitor the movement of the subject while simultaneously not interrupting his or her daily routines. Also, more functional, lighter, more reliable optical tracking ...
