Emergency alarm: An emergency alarm is normally a device which contains buttons that is pressed when a user is in a dangerous or emergency situation and requires immediate help as illustrated in Figure 3. When a button is pressed, the device is automatically sent an emergency message to a designated person or organisations such as family, doctors, polices and etc. The device can be programmed to assign
different button to each contact, for example button A for ambulance. The emergency alarm is also equipped with a location sensing sensor such as Global Positioning System (GPS) allowing location information to be sent with the emergency message resulting in quick response to the incident.
