Abstract

Systems and methods are provided that allow caregivers, central monitoring services, and other persons to monitor whether a monitored individual'"'"'s hands have entered into an area in which the hands are prohibited, such as areas in which the monitored individual may remove or disturb a piece of medical equipment. When the monitored individual'"'"'s hands do enter the restricted area that is represented by an electronic virtual safety zone, an alert is generated and transmitted to a designated recipient.

Claims

1. A computerized method for detecting when a monitored individual has moved one or both of his or her hands within a virtual safety zone, the method executed by one or more processors and comprising:

receiving video data from one or more 3D motion sensors capturing live video data of an individual to be monitored within a monitored area;

defining a virtual safety zone representing an area in which the individual should not place his or her hands, the virtual safety zone encompassing at least part of the individual'"'"'s face;

determining that one or more hands of the individual are within the virtual safety zone based on at least a partially lost or obscured facial tracking signal; and

upon determining that the one or more hands of the individual are within the virtual safety zone, electronically transmitting an alert to at least one designated recipient.

2. The computerized method of claim 1 further comprising determining whether one or more hands of the individual remain within the virtual safety zone for at least a predetermined period of time.

3. The computerized method of claim 2, wherein the alert is electronically transmitted only upon determining one or more hands of the individual remained within the virtual safety zone for at least the predetermined period of time.

4. The computerized method of claim 2 further comprising continuously displaying a live video feed of the virtual safety zone received from the one or more 3D motion sensors on a centralized monitoring alert display after it has been determined that one or more hands of the individual remained within the virtual safety zone for at least the predetermined period of time.

5. The computerized method of claim 1 further comprising continuously displaying a live video feed of the virtual safety zone received from the one or more 3D motion sensors on a centralized monitoring primary display that is remotely located from the monitored area.

6. The computerized method of claim 5 further comprising continuously displaying a live video feed of the monitored area received from the one or more 3D motion sensors on a centralized monitoring alert display after it has been determined that one or more hands of the individual are within the virtual safety zone, wherein the centralized monitoring alert display is a separate display from the centralized monitoring primary display.

7. The computerized method of claim 1 further comprising updating a database regarding the determination that one or more hands of the individual was within the virtual safety zone.

8. The computerized method of claim 1, wherein the designated recipient includes one or more of the individual, a caregiver, an alternate caregiver, and a supervisor.

9. The method of claim 1, wherein the virtual safety zone is defined using at least facial tracking to recognize the individual'"'"'s face.

10. A system for determining whether a monitored individual has placed one or both hands in a virtual safety zone, the system comprising:

one or more 3D motion sensors capturing live video data of an individual to be monitored;

a computerized monitoring system, the computerized monitoring system configured to;

receive video data from the one or more 3D motion sensors;

define a virtual safety zone representing an area in which the individual should not place his or her hands, the virtual safety zone encompassing at least part of the individual'"'"'s face;

determine that one or more hands of the individual are within the virtual safety zone based on at least a partially lost or obscured facial tracking signal; and

upon determining that the one or more hands of the individual are within the virtual safety zone, electronically transmit an alert to at least one designated recipient.

11. The system of claim 10 further comprising:

a computerized communication system configured to receive from the computerized monitoring system a determination that one or more hands of the individual entered the virtual safety zone.

12. The system of claim 11, wherein the computerized monitoring system is further configured to actuate a timer upon determining that one or more hands of the individual entered a virtual safety zone.

13. The system of claim 12, wherein the computerized monitoring system sends to the computerized communication system the determination that one or more hands of the individual entered a virtual safety zone only if the one or more hands remain in the virtual safety zone for at least a predetermined period of time.

14. The system of claim 10, wherein the designated recipient includes one or more of the individual, a caregiver, an alternate caregiver, and a supervisor.

15. The system of claim 10, wherein the alert comprises an audible instruction to the monitored individual.

16. The system of claim 10 further comprising a database for logging events related to the one or more hands of the individual entering the virtual safety zone.

17. The system of claim 10, wherein the virtual safety zone is defined using at least facial tracking to recognize the individual'"'"'s face.

18. Non-transitory computer-readable storage media having stored thereon executable instructions that, when executed by a computer, cause the computer to:

receive video data from one or more 3D motion sensors capturing live video data of an individual to be monitored;

define a virtual safety zone representing an area in which the individual should not place his or her hands, the virtual safety zone encompassing at least part of the individual'"'"'s face;

determine that one or more hands of the individual are within the virtual safety zone based on at least a partially lost or obscured facial tracking signal; and

upon determining that the one or more hands of the individual are within the virtual safety zone, electronically transmit an alert to at least one designated recipient.

19. The media of claim 18, wherein the virtual safety zone is defined using at least user input.

20. The media of claim 18, wherein the instructions further cause the computer to log the alert in a database.
