Abstract

In one embodiment, a device obtains sensor data captured by one or more sensors deployed in a washroom, the sensor data comprising audio signals. The device identifies, using the sensor data as input to one or more machine learning-based classifiers, one or more events associated with a user of the washroom. The device makes a decision as whether the one or more events comply with a hand hygiene protocol. The device provides data indicative of the decision for presentation to the user.

Claims (44)

1. A method comprising:

obtaining, by a device, sensor data captured by one or more sensors deployed in a washroom, the sensor data comprising audio signals;

identifying, by the device and using the sensor data as input to one or more machine learning-based classifiers, one or more events associated with a user of the washroom;

identifying, by the device and based on the sensor data, a maintenance issue associated with the washroom;

modifying, by the device and based on the sensor data and on the identified maintenance issue, one or more steps of a hand hygiene protocol;

after modifying the one or more steps of the hand hygiene protocol, making, by the device, a decision as to whether the one or more events comply with the hand hygiene protocol; and

providing, by the device, data indicative of the decision for presentation to the user.

2. The method as in claim 1 , wherein the sensor data further comprises motion signals indicative of movements by the user.

3. The method as in claim 2 , wherein the one or more machine learning-based classifiers comprises a motion classifier.

4. The method as in claim 1 , wherein providing the data indicative of the decision for presentation to the user comprises:

customizing the data indicative of the decision based in part on a history of compliance with the hand hygiene protocol by the user.

5. The method as in claim 1 , wherein the data indicative of the decision further indicates a comparison between the decision and other decisions made regarding compliance with the hand hygiene protocol by others.

6. The method as in claim 1 , further comprising:

sending, by the device, an alert regarding the identified maintenance issue.

7. The method as in claim 1 , wherein the identified maintenance issue is selected from a group consisting of: no soap, no paper towels, a broken towel dispenser, a broken soap dispenser, a dirty washroom, and a dirty sink.

8. The method as in claim 1 , wherein the sensor data comprises voice recognition data, and the maintenance issue is identified based on the voice recognition data.

9. The method as in claim 1 , wherein the one or more sensors comprises a Radio Frequency Identification (RFID) reader.

10. The method as in claim 1 , wherein identifying the one or more events associated with the user comprises:

obfuscating, by the device, personally identifiable information of the user that is present in the sensor data.

11. The method as in claim 1 , further comprising:

providing, by the device, data indicative of a step of the hand hygiene protocol for presentation to the user, prior to identifying the one or more events.

12. The method as in claim 1 , wherein the audio signals are indicative of running water or of use of soap by the user.

13. The method as in claim 1 , wherein the data indicative of the decision comprises an instruction to perform a particular step of the hand hygiene protocol.

14. The method as in claim 1 , further comprising:

outputting, by the device, music via an audio output device for a period during which one or more steps of the hand hygiene protocol are to be completed.

15. The method as in claim 1 , wherein the provided data comprises display data for presentation by an electronic display, the display data comprising a time counting element alongside a graphical indication of a step of the hand hygiene protocol.

16. The method as in claim 1 , wherein the one or more sensors deployed to the washroom comprises a thermal sensor.

17. An apparatus comprising:

one or more interfaces;

a microprocessor coupled to the one or more interfaces; and

a memory storing instructions that, when executed by the microprocessor, are configured to:

obtain sensor data captured by one or more sensors deployed in a washroom, the sensor data comprising audio signals;

identify, using the sensor data as input to one or more machine learning-based classifiers, one or more events associated with a user of the washroom;

identify, based on the sensor data, a maintenance issue associated with the washroom;

modify, based on the sensor data and on the identified maintenance issue, one or more steps of a hand hygiene protocol;

after modifying the one or more steps of the hand hygiene protocol, make a decision as to whether the one or more events comply with the hand hygiene protocol; and

provide data indicative of the decision for presentation to the user.

18. A tangible, non-transitory, computer-readable medium storing program instructions that cause a device to execute a process comprising:

obtaining, by the device, sensor data captured by one or more sensors deployed in a washroom, the sensor data comprising audio signals;

identifying, by the device and using the sensor data as input to one or more machine learning-based classifiers, one or more events associated with a user of the washroom;

identifying, by the device and based on the sensor data, a maintenance issue associated with the washroom;

modifying, by the device and based on the sensor data and on the identified maintenance issue, one or more steps of a hand hygiene protocol;

after modifying the one or more steps of the hand hygiene protocol, making, by the device, a decision as to whether the one or more events comply with the hand hygiene protocol; and

providing, by the device, data indicative of the decision for presentation to the user.
