Smart postural monitor for elderly people

Efficient, low cost and easily deployable elderly people monitoring systems are becoming every day more important due to the always increasing average age of the populations all over the world. For elderly people, wrong postural behaviors can indicate a main and preliminary marker of malaise. It is possible to be made aware of this kind of problems developing smart home monitoring technologies: the body posture can be modeled using information resulting from specific low cost sensors built-in a bed or an armchair. This paper presents a low cost smartphone application for such application, able to transform a bed or an armchair into an intelligent device. A friendly interface has been defined in order to make this application also suitable for unskilled users.
