The client is a power wheelchair user who wishes to go out on his own but is unable to grasp and use a mobile ‘phone to call his wife if he needs assistance.
A GPS tracker which sends a text message containing a link to an on-screen map showing the tracker’s location to a chosen mobile ‘phone number was obtained. The tracker was modified by connecting wiring to its emergency call button. A small push button box with a neck band was made so that the client can operate the button by moving his chin down.
The client can now alert his wife while he is out on his own, if he needs help.
