Gloucester Smart House - help for dementia sufferers
From: Tech Eye for the Older Guy and Gal - 12/31/2007

Engineers from the Bath Institute of Medical Engineering have designed
special sensors that can wirelessly ‘talk’ to devices in response to the
behavior of the resident. The smart house uses a series of sensors to
monitor the occupant's behaviour and responds to problem situations by
activating a series of support devices, such as automatic lighting. The
system is able to respond to many different situations without having to
contact care staff, often just using simple voice prompts. The hope is that
everyday tasks would almost take care of themselves, allowing dementia
patients to continue with their lives as normally as possible.
