A method for monitoring an individual in a dwelling so as to know when such individual falls or indicates the need of assistance. A plurality of 3D motion and sound sensors are located in the dwelling and provide data to a computerized monitoring system. The sensors are configured to recognize one or more biometric identifiers of the individual being monitored, which are used to track the individual's movement. When the monitoring system detects that the individual has fallen or gestured for assistance, a computerized communication system alerts the individual, a caregiver, or other designated person.
