If a fall is detected, there are three possibilities, depending
on the action of the patient. First, if there is no fall (false
alarm), the patient uses the cancel button to stop the alarm and
inform the software of the false alarm. Second, if the patient
falls, but needs no help, another button is pressed to stop the
alarm and inform the software, which is then notifies the doctor
and carer. Finally, if the patient is unable to use button (this
means a fall), an alarm is sent to the doctor and carers.
Meanwhile, in all cases, the watch alarm is set off.
