Alcatel is also working on monitoring for aged care. While this device looks like a panic button, it links via a mobile phone network to a call centre when pressed. The elderly person can then talk to the call centre about their problem, or if they don't speak after pressing the button, an emergency call is made.
It can also be set to monitor when the person steps out of set boundaries, which is especially useful for patients with dementia. The mobile device is also in a bracelet form.
If the patient feels the need for some one-on-one chat, software installed on a set-top box enables video calls to the call centre and to other people such as their children.
Other forms of aged care monitoring do not require the elderly person to carry anything around with them. QuietCare monitors people in their home via five to eight of these sensors (left) placed around the house. They measure elements such as motion in rooms, or room temperature. The information is sent to a home base station (right) which every few hours passes information on to a centre. Algorithms work out if the person is doing anything out of the ordinary.
