Tomorrow’s cities: Sensor networks for the elderly | BBC News
Helge and Kari Farsund, who live in Oslo, Norway, have been a couple for 50 years. Mr Farsund worked as an engineer, while his wife was an intensive-care nurse, at one point serving with the Red Cross in Rwanda, helping victims of the violent war in that country.
Three years ago, a more personal tragedy struck, when Mrs Farsund was diagnosed with Alzheimer’s.
As the condition deteriorated, Mr Farsund began looking for a system that could help both of them live as normal a life as possible.
