AI in healthcare: Fascinating tech, but is it actually saving lives?

In an unassuming two-storey Victorian town house in Bristol, the occupants are being filmed, monitored, and tracked by invisible sensors as they go about their business, 24 hours a day. What they lose in privacy could be our gain in life expectancy, if the long-term data bears out. Pivotal to the 15-million Sensor Platform for Healthcare in a Residential Environment (SPHERE) project, the house has been invisibly fitted with dozens of cameras and sensors while its occupants are asked to don wearable devices. The aim is to reveal how health is related to everyday lifestyle and living conditions over time. The smart home observes how long the occupants slouch in front of the TV as opposed to sitting or walking or exercising.
