Method for determining whether an individual enters a prescribed virtual zone using skeletal tracking and 3D blob detection
First Claim
1. A method for detecting when a monitored individual or any part of the monitored individual has crossed over a designated electronic perimeter, said method comprising the steps of:
- (a) electronically receiving data by a computerized monitoring system from one or more 3D Camera, Motion and Sound sensors located in the room;
(b) tracking a monitored individual using skeletal tracking if a skeleton is detected;
(c) tracking the monitored individual using virtual blob detection if a skeleton is not detected; and
(d) electronically determining by the computerized monitoring system that the monitored individual has crossed a predetermined designated electronic perimeter by either electronic skeletal tracking of the monitored individual or by virtual blob detection.

Abstract
A method and system that allows healthcare providers, hospitals, skilled nursing facilities and other persons to monitor disabled, elderly or other high-risk individuals to prevent or reduce falls and/or mitigate the impact of a fall by delivering automated notification of “at risk” behavior and falls by such an individual being monitored where assistance is required. Two systems are used to identify patients, a skeletal tracking system, which identifies patients by biometric indicators, and a virtual blob detection system. In the virtual blob system, the monitored individual is virtually represented as a blob object of at least a specific size by a computerized monitoring system and such system detects and alerts when the blob object enters or crosses into a virtually defined or designated blob detection zone and remains in the zone for at least a predetermined period of time. These systems may be used concurrently, or one system may be used primarily, with the other system acting as a failsafe.

11. A method for electronically monitoring for when an individual or any part of the individual crosses over a designated electronic perimeter, said method comprising the steps of:
-
(a) electronically receiving data by a computerized monitoring system from one or more 3D Camera, Motion and Sound sensors located in a room; (b) tracking an individual using skeletal tracking if a skeleton is detected; (c) tracking the individual using virtual blob detection if a skeleton is not detected; and (d) electronically monitoring the room by the computerized monitoring system for a crossing of a designated electronic perimeter by the individual based on the data electronically received from the one or more 3D Camera, Motion and Sound sensors by either electronic skeletal tracking of the individual or by virtual blob detection. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A method for electronically monitoring of when an individual or any part of the individual crosses over a designated electronic perimeter, said method comprising the steps of:
-
(a) electronically receiving data by a computerized monitoring system from one or more 3D Camera, Motion and Sound sensors located in a room; and (b) electronically monitoring the room by the computerized monitoring system for a crossing of a designated electronic perimeter by the individual based on the data electronically received from the one or more 3D Camera, Motion and Sound sensors, simultaneously using skeletal tracking monitoring based on skeletal points for the individual and virtual blob detection monitoring by the computerized monitoring system for detecting a perimeter crossing by the individual.
