Prototype 2: Monitoring Health & Providing Safety

The idea is similar to the one below. However the watch would have no interface apart from one button situated at the side of the watch. The main function of the watch would be to just tell the time (whilst in the background monitor certain health conditions).

The side button would communicate with a security system placed around the house. When a elderly user leaves the home, they can press this button to alarm their property or deactivate the alarm when they re-enter. PIR Sensors would do the job of monitoring unauthorized movement within the house and send a silent alarm off to security centre. They will also have the job of monitoring the 'elderly watch-user' - if no movement is detected for a prolonged period of time and the watch has detected a health anomaly - then the emergency services will the notified.

Finally there would be a need for a device to set the system up and also to view statistics stored from the watch. I propose a touchscreen/graphics pad for this job - large icons can be displayed that the user can easily see. Also rather than typing any setting - a graphics pen can be used to write them in (most elderly can still write).

Each device will communicate with each other through Bluetooth technology and powered by rechargeable batteries.
