Emergency detection systems for senior citizens: "IESE scientists are working on an unobtrusive system that provides constant 'companionship' to elderly people living in single households or in retirement facilities. Multisensory nodes mounted to the ceiling of a room register an individual's movements.
'Our system records how long a person spends in what part of the home,' notes Holger Storf, a scientist at IESE. A radio signal transmits the data to a computer. Software documents the individual's daily activities, constantly learning the person's 'normal behavior.' The analytical software compares the resident's current activity with the model that has been generated."
