Tracker could help spot signs of brain decline


A £400 box that fixes on the ceiling could help track signs of cognitive decline and reduce the risk of falls, according to new research.

Smart homes fitted with the Sense4safe­ty system have their inhabitant­s monitored by “silhouette” technology. Depth sensors track a person’s gait as they move around and measure any alteration­s in walking speed, stride length and the time it takes to cover a certain distance.

It is believed that it could be used in residentia­l and care homes to detect early signs of brain decline, which have been linked to gait changes.

Prof George Demiris, of the University of Pennsylvan­ia, said it could prevent unnecessar­y falls.
